Andy C, and others, Thanks. I am using networks for imaging the interior of the earth, the atmosphere and ocean currents, the electron density. So yes you can use electromagnetic and gravitational fields to find your lost golf ball - one day.![]()
@W4KRL I will be on a show showing off some of the newer things ham radio can do, well beyond sitting at home having a rag-chew (informal chit-chat)![]()
Josh and all, I think that where we get the most traction with attracting interest and retaining interest is with anything that is activity based: SOTA, T-hunts, race comm, building antennas, projects, etc. HF keeps me interested in amateur radio, especially contesting. I operate the California QSO Party yearly and have gone on several county expeditions... a sort of SOTA on steroids. Over 40 groups went out on county expeditions last year. http://cqp.org/ BTW Josh, thanks for participating last year. You're in the results.![]()
@W4KRL - I'm not young. I resemble that "beginner rig" remark well. ;) I do come from a different network world, but I remember dialup (I actually miss it) and being in disaster volunteering now - I see how important legacy slow data exchange will be neccessary.![]()
@KI6NAZ Josh then you know more than I (which is nothing), but it certainly seemed weird, and if there were conflicts, shouldn't that have already been known /beforehand/? but thanks for your insight.![]()
How can we learn more about the people who do SOTA and invite them to join other groups for county expeditions?![]()
@Dean Yeah! That was a lot of fun!![]()
@ziggurat29 yes, in the end it was his responsibility to cut ties and he might now have.![]()
It was a great time![]()
So in a way I fell in love with HAM because I wanted to re-live the old FIDO net data days. I do miss the sound of that 300 baud handshake. ;)![]()
This was my new favorite ham meeting!![]()
@Dean Hop on the SOTA reflector and post there.![]()
@Andy C It turns ME off to attend a ham club! First, everyone is 110 years old and the main topic of discussion is health-related. And I hate to bring this up but I get really turned off by teh political discussions. I think it should not be part of the meeting topic but I guess it is hard for people to compartmentalise.![]()
Thanks![]()
Thanks to the hosts and the presenters for the convo and forum!![]()
LOL![]()
Its been fun! Feel free to email me or comment on YouTube. Hoshnasi@gmail.com![]()
@Dan Twedt join the HRCC discord. There are a lot of people like this there![]()
Super interesting discussion everyone, but our hour is up and Josh probably has to get back to the real world. I really want to thank him for spending his lunch hour with us, and to everyone for the great discussion. Feel free to stay on the channel and keep the conversation going.![]()
Would love to keep this discussion going. Thanks to all.![]()
Anyone have any luck with in recruiting storm spotters/ storm chaser to amateur radio? Storm spotter training season. is upon us. N0LKK![]()

Thanks all! Keep spreading the love of radio!![]()
I had an idea for a QSO party.. perhaps next year, people in the two states who have teams in the superbowl could contest to talk make contacts. Then the score of the game could be a multipier. What do you think?![]()
And don't forget next week we'll turn out antennas to the skies with DIY Radio Telescopes:![]()

@Dan Maloney well, you can't encrypt the transport of data, and that makes folks jittery. but I understand that runs against the openness of ham. In truth, we /can/ do a little encryption...we are allowed to use encryption for the purpose of authentication.
![]()
Can we have a predictably spread spectrum?![]()
I think you mean PACTOR![]()
if we had more ARRL clout and younger hams who can make a case to them and thus the FCC, we could make that change for the better, but until them we can only use encryption on Part 15 ISM bands, or very carefully walk around the "obscuring the message" wording of the regulations![]()
Sure, PACTOR as used for Winlink among other modes.![]()
You can't "obscure the message" according to US rules, you can still use encryption for authentication purposes.![]()
so we can make some sort of ham-radio-enabled-garage-door-opener that the commands are visible, but that the authentication to issue3 the commands use encryption to prevent unauthorized use. so we at least have that level of encryption.![]()
The problem I see with allowing encryption is I could see the drug traffickers jumping on the bandwagon and making a bad name for HAM they way they have done for bitcoin.![]()
Interesting idea @ziggurat29![]()
Esperanto used to be an official language of ham. That's almost encryption lol.![]()
My personal experience: an RTL-SDR got me interested a few years ago. I got my technician and general, bought a radio, did some 20m, FT8 especially, but then lost interest and sold my radio. Just seemed like not that much was going on. The technical aspects of it are definitely more interesting to me than making connections, but once the thrill of getting an FT8 contact from another continent wears off it's pretty boring. Add to that, I don't like heights or have a lot of space so big HF antennas are out for me.![]()
I work with people building sensitive gravity transmitters and receivers for testing speed of gravity. If you switch to gravity signals, you would not need much encryption. It is at the same level that spark transmitters were a hundred or more years ago. But improving quickly.![]()
what's RTL-SRD?![]()
gravity mode...genius wow!![]()
@J.B. Langston satellites can be really fun.![]()
Try JS8CALL if you have the hang of FT8 and routing contacts through other stations. Also, I still find AX25 packet to be an a great time.![]()
However, I wqould rather that there be some licensing rules changed that you are permitted to (and I'm making it up rigbh now) that you are permitted to use a certain bandwidth on a band for a certain duty cycle to transmit arbitrary encrypted data.So you are still polite with respect to everyone elses use of the bandwidth, but you are free to do your 'whatever' experiments.
![]()
RTL-SDR is a cheap USB software defined radio. cost like $20. it was meant to be a DVB tuner but got hacked to access a wide swath of spectrum.![]()
@Andy C RTL (Realtek) SDR (Software Defined Radio). There's a cheap DVB-T receiver chip from Realtek that's a base of a lot of SDR USB dongles![]()
@Andy C Its a Software Defined Radio receiver. Cheap off Amazon![]()
@Andy C https://www.rtl-sdr.com/about-rtl-sdr/![]()
@Andy C - SDR == Software Defined Radio. RTL-SDR is a brand of SDRs based on digital TV USB dongles.![]()
Josh the encoding that allow compresion on PBBS networks, sent the call signs of participating stations in the clear, the same could be done with encryption.![]()
This is true!![]()
Im very new, gifted a Galaxy V radio by KIOOT.. Have not turned it on 1) No License 2) no antennae.. Working on #1 ... and #2 Have 35 ft tower with noting on it.![]()
Rtlsdr got me back into Ham Radio after a 20 year lag. Great tool for awaking engineering spirits![]()
A tower with nothing on it? Horrors!![]()
my question is what should go on it.![]()
@KI6NAZ Josh your point about 'how do we know' is well taken; however, how do we know now? I could simply go on the air and claim to be KI6NAZ and there it is? There is no cryptographic security in the medium to begin with. If I were a bad actor, that's just what I would do anyway.![]()
PBBS packet stations are interesting because they get around the line of sight nature of VHF, by routing messages through distant stations. You can tunnel through and make some impressive comms with that.![]()
I have an amp that’s not hooked up.![]()
What are the status of HSMM broadband hamnets in most cities?![]()
@ziggurat29 true enough, I am not defending their position, just stating what I think the concern is.![]()
@Matt Quince that should be illegal lol![]()
@brianmhff661 whatever you want, I'd start out with a simple HF inverted V + some VHF/UHF antennas. Then see which part of the hobby is most fun for you.![]()
We used to have an HSMM net in Omaha, but I think it slowly fizzled away due to lack on interest![]()
@GusGorman Hit and miss. In SoCal mesh networking is pretty popular. Ubiquity gear is well priced and some have some impressive nets setup.![]()
Back to the "connecting people" part, I'm on Zello via the app on my android phone. There are many open groups there, where people love to chat and build strong friendships even (stronger than many I might have with someone I exchange a signal report with). So, I would love to talk to a phychologist about what's going on there. What's the attraction to connect with total strangers? One idea I have is, these quick qso's are very low on the drama scale. We get to chat with someone and see how far our antenna got, but the emotional baggage is almost nil. I think that fills a void for some... they have a feeling of connecting without having to go too deep. (no politics, religion etc).![]()
@Andy C i see this in our discord.![]()
@KI6NAZ Josh fair enough; the topic was 'keeping ham fresh in the 21st century' and I personally have a strong opinion on digital and encryption aspects, so that's why I'm arguing them! lol!![]()
@Andy C I see that same thing on our local repeaters. People become friends never seeing the other person, as we do on the internet today.![]()
makdaam thanks for feed back![]()
Is ham radio a global thing? Do all countries have hams?![]()
BTW We have high speed ham internet blanketing the Conejo Valley here in Ventura County thanks to some dedicated CVARC members.![]()
@RichardCollins yes. most.![]()
@RichardCollins - Yep, except maybe North Korea. I might be wrong about that though![]()
@RichardCollins more or less. Some states are more restricted. North Korea has very few if any hams.![]()
@Richard Hogben no hams are US specific, but other countries have amateur radio operators :P![]()
Personally, I sort of like the public service aspect too. If my ham club is supporting a bike race where cell towers can't reach, it actually serves a real purpose. We've had cases of getting messages to EMS that otherwise would have been very hard to do.![]()
To try and pull it back a bit into “keeping ham radio relevant”. I would remind people that radio is adaptable. Licensed hams have the ability to adapt some for of radio into most of their projects or interests, we just need to leverage it appropriately. As I mentioned earlier, raspberry pi, SDRs and new data modes can all be used.![]()
@GusGorman @KI6NAZ not much mesh here. I've got a bunch of ubiquity gear here, but working on connecting them to someone. So far not many people in Forest Grove, ORyet.
![]()
in all seriousness though all democratic countries that I know issue licenses, and some not so democratic too![]()
^ one of the reasons I want to get licensed, I've seen a couple bad accidents back country mountain biking![]()
CERT classes should all have a ham visit.![]()
For those going outdoors, I’d take a look at APRS enabled radios. I use one in the field. They work well to keep people updated on your status.![]()
Josh apparently hams in the USA are HAM(S) ;)![]()
I am CERT in Cerritos Ca. I agree, they need WAY more comms.![]()
I’m a ham HAM![]()
:D![]()
@KI6NAZ Josh - But, there's a lot of headwind with the older crowd to these new technologies. I was at an ARES meeting where a guy was showing off a Pi-based Winlink gateway he built, and nobody there grokked it. At all. Felt bad for the guy, really.![]()
I see the opposite.![]()
At least here in sw Fl.![]()
The hobby has room for the whole spectrum!![]()
I've tried to pass a few messages recently through RadioGrams. Total fail both times. If we still want to be seen as a communication when all else fails, we need to actually pass messages when asked to. (stepping down from soap box). :-)![]()
Winlink isn't really new. I would gather the interest level is empowered by the relevance to the location. If your only ARES activations are for for those parades, walk-a-thons, and 10ks, you're not going to get interest.![]()
@Dan Maloney I highly recommend people start to compartmentalize ham radio. You can be a member of a traditional club, but don’t expect they’ll “get” the new stuff. With that said, there are LOTS of ham radio communities online. Our HRCC discord in particular is a great place for those interested in newer tech to get support/community.![]()
One of my favorite clubs is the Long Island CW club, they only meet on Zoom and its great.![]()
deffinitely![]()
Definitely. Good community![]()
Radiograms are great. Earthquake Lady Dr. Kate Hutton is the guru there too!![]()
ty @Matt Quince![]()
It does vary from group to group, the worst part is that I think most of us don't advertise the diversity of clubs.![]()
Is there something equivalent to email through ham bands? Where you message someone and they can hear it later and respond? Is that the networks you were talking about? It is the "is there anyone there?" part of ham that was always offputting to me. Is that a radiogram?![]()
That's a good point. And really, the ARES people are already invested, so it's not going to further the mission of bringing in new hams![]()
@Dan Maloney You hit the nail on the head. A lot of older hams are Luddites and a real turn off for younger people who may be interested.![]()
@Makdaam yes, this will have to change in the future. By the nature of hams getting older and new generations becoming interesed it has already started.![]()
So this is kinda a niche question but I believe could really aid an often overlooked group. As a falconer I know of atleast 8 birds that were lost during flights. How hard would it be to break out a yogi and try to find a signal in the 216 mhz . Some of these birds are worth a small fortune and carry multiple beacon trackers on them. Most in the 216 and 434 range. Going to a local falconry club may be a way to get some folks into ham and notify of an available resource to help track lost birds. Just a thought.![]()
If you want to totally kill the interest in ham radio for someone in my area, bring them to our club meeting.![]()
I think the Radiogram System is mostly for Health and Welfare related message traffic.![]()
@RichardCollins JS8CALL will store messages you receive while away. Many use it similar to packet stations over HF.![]()
I use ham radio to recover high power rockets.![]()
@W4KRL - When I shared this discussion with PNW groups. The "ludite" claim came up from younger HAMs. Of course there were replies to the instant gratification of phone app HAM users too by the legacy operators.![]()
You might broaden the community, if you can tone down the abbreviations and jargon. I like that comment about falcons, that is real. How the communication gets done on what frequency, not so much.![]()
@KI6NAZ Josh it has started, but it's a bottom up movement. Which is not bad by itself. But at the same time I can see the younger generation isolated from all the IARU business because they're not a part of the old club, the external politics are also important.![]()
@makdamm look at the new ARRL magazine On The Air. The see the changing winds.![]()
good for you :) I'm mostly thinking about my local area in DL/SP![]()
@Makdaam *ding* politics. old and new![]()
Radiograms are a way to pass a message, in theory with no use of the internet end to end. WINLINK is a ham based email system that can be used to send an email when you don't have internet. You're computer contects to your radio and you send it to a receiving station than can then forward it via the regular internet. pretty cool.![]()
Hamfests in the SW US are a pretty gray crowd, but I see more young people there as time goes on.![]()
Understood. Smaller groups may still have a hive mind appearance when it comes to things. Thankfully we’re an online people now.![]()
WinLink is used by a lot of CERT groups when training and operating the emergency stations at Fire and other EMS locations as it supports document exchange over HAM easily.![]()
Could I use Ham Radio to find my lost golf ball? LOL![]()
ARRL funny origin story: Hiram Maxim was too cheap to telegram for a tube he needed from Connecticut.![]()
unpleasant topic, but maybe relevant: the ARRL is our lobbying organization. our hobby lobby. so, they fired the CEO recently. WTF?![]()
The good news about all this information being online is that you don’t have to be beholden to what the local club find interesting. Feel free to research your own projects and fail as many times as you need to to make it work. I know I do :D![]()
@eric.j.brewer Too often the media (if it notices us at all) play up the obsolete communications aspect of amateur radio like Morse and AM. We have to counter that image. Another aspect is equipment snobbery. Older hams have built up stations over decades and scoff at kids with entry-level rigs. That does no good to attract new hams.![]()
@ziggurat29 This is likely due to his not relinquishing his ties to his other businesses.![]()
A local group in my area has been pushing really hard to have an annual showing at our State Fair. To raise interest in the gen.pub.![]()
Scenario might play out. Falconer notifies group of loss of bird and what area. Local Ham group notified of signal tracker freq. and can notify falconry group if the signal pops up. The comms between hams would be between them however they want.![]()
Andy C, and others, Thanks. I am using networks for imaging the interior of the earth, the atmosphere and ocean currents, the e -
Hack Chat Transcript, Part 2
02/05/2020 at 21:03 • 0 comments![]()
@Martin Mortensen There are many texting type of modes in ham radio, both VHF/UHF like we get access as technicians and HF where we can make longer distances contacts. One that comes to mind is APRS. Which can send multiple types of data.![]()
@ashok das - Absolutely. CW punches through like nothing else. Requires almost no bandwidth.![]()
The 'trouble' I see in FT8 is that it is not conversational -- it is transactional. Which is fine if your goal is log contacts, but not particularly interesting in you want to engage. Speaking personally, if I just want to see my signal propagation, I have WSPR, and I don't have to worry about whether the other party chooses to engage.![]()
@Ashok CW “goes further” because it takes up less bandwidth than voice. Further, its not as complex to hear, Dits or Dahs can be picked out of the noise by the human ear easier than the nuances of voice.![]()
Ham radio used to require some technical interest (engineering, electronics) as you might need to build your own radio or repair it. So it would attract those sorts of folks. But then there's still something innately interesting to me at least about making contacts. There's something about Ham that's different than just calling up a friend to chat. The fact that both parties, by virtue of being "on the air" are saying they are open to making a new contact is what seems to draw me to it. I've been thinking a lot about why I find Ham Radio interesting. It doesn't make a ton on sense to a lot of my friends. So there's something deeper.![]()
@ziggurat29 Look into JS8CALL, its conversational FT8 basically.![]()
CW Ops is a tremendous organization to learn CW and link up with mentors and a training method. https://cwops.org/![]()
@KI6NAZ Josh thanks I will![]()
I was just getting ready to say that, JS8Call looks like the best of both worlds![]()
Then there's the experimenting with antennas, and modes to see how far you can get a signal to reach. (back to the science stuff, vs personal relationship stuff).![]()
This week I've shared the article and HackChat link to:FB: "Team Rubicon Pacific Northwest (WA & OR)"
FB: "Team Rubicon Amateur Radio Operators"
FB: "King County C.E.R.T"
FB: "Pacific Northwest CERT"
FB: "PSRG Puget Sound Repeater Group"
FB: "Puget Sound Mike and Key"
Overall the biggest interest was in creating some joint "outreach" to schools and groups that is ACTIVE? One of the ways to keep such things active and mobile would be your local schools could write off a couple old buses for use as mobile ham training rigs that could visit schools on schedule to get the SCIENCE of radio and electronics back into the education system for early starters?!
![]()
(our U.S. Navy needs to go back to teaching CW and celestial nav to sailors too)![]()
@Andy C The cool part about radio is that you can do any and all of that. Building rigs or antennas. Or just making contacts. I really like to build antennas and that has given me a lot of joy.![]()
Despite all the people who say CW is "dead" it is amazing how often it pops up in non-ham places (e.g. TV programs, movies, commercials).![]()
@eric.j.brewer I’ve found that for most people showing live demonstration is what makes radio real. If you bring an experiment or something someone can go hands on with, its really becomes sticky to them and builds interest.![]()
Here's the thing, though - are we going the wrong way by trying to concentrate on "texting you can do on ham radio"? I think so - they've already got a texting platform. Maybe we should concentrate on the non-conversational aspects - just the coolness factor of being able to put together a transmitter from a few parts and make a contact.![]()
RTL-SDR workshops help get kids involved too. They might not be interested in HAM at first, but learning to hack keyfobs and do bug detection, that sparks their interest![]()
exactly- and seeing what @Kevin said backs up - you still see it on things like NCIS and such on TV. But where do people FEEL the hobby? Local county fair if lucky?![]()
@Dan Maloney I would agree. I like to sell it as Self-Supported communication. No one can take away what you know and how you operate. If its voice, or data, you’re in control and that brings some pride to it in seeing it all work.![]()
@KI6NAZ Josh - My dad and I are both hams. I once told him that they should call it Amateur Antenna, not Amateur Radio.![]()
I was just talking to James Aguirre, who is going to do Hack Chat soon on radio telescopes.Are hams involved in monitoring electromagnetic interference? The radio telescopes have to monitor from their sites, but need local verification of some transmitters. Ditto on SDR.
![]()
@Dan Maloney ++, amateur radio shouldn't be advertised as a communication medium, there's better ways to reach your friends, coolness factor is much more important![]()
@eric.j.brewer Ham radio got used in an episode of NCIS but they almost totally messed it up as they were mixing in aspects of CB radio with ham radio.![]()
@GusGorman I agree, SDR receivers play a big role in demonstrating radio. They are cheap and give visual evidence that it is working. I have used SDR to display the waterfall of incoming SSTV images in classrooms and it makes real.![]()
There's been several in the cryptocurrency community that have taken an interest in HAM for off-grid transactions![]()
Hi Hosh![]()
@Kevin - I know I wince at many NCIS things they portray on TV. (To which I often wonder if they mislead by purpose?)![]()
Josh, I'm interested in hearing more details about your opinion from the promo to this chat - that EMCOMM perhaps is not the savior of amateur radio and that potential hams could be more interested in joining amateur radio through things like SOTA. Could you please expand?![]()
@RichardCollins i used to work at the VLA (which employed tons of hams too). Many hams will use RDF to locate interference, especially when it impacts their repeaters.![]()
@RichardCollins I made a video recently on tracking down RFI at home. Hams are innately interested in tracking down interference whenever possible.![]()
solarcoin should be the unofficial digital exchange of ham radio!![]()
Using radio to make crypto transactions, I've had a few kids think that was cool![]()
@dean - to be clear, that was my position, not necessarily Josh's![]()
ah, thanks Dan![]()
I have to disagree somewhat that using the medium as a text-based mechanism is a distraction from the fundamental intent of ham. Ham is about communications, and whether that information is analog (phone) or numeric (digital) is orthogonal to the details of the art.![]()
@Dan Maloney It is useful to point out that amateur radio operators can communicate with people that can't be reached by that thing they usually carry around in their pocket, or by regular landline telephone. Isolated islands or the ISS are a couple of examples.![]()
I recently 3D printed a crude acoustic coupler for use with minimodem too. 3D modeling for antenna design too is also fun.![]()
Also useful to point out its use in emergency situations.![]()
@GusGorman the whole "pecuniary interest" rule is a huge grey area on using ham radio to transmit cryptocoins, and the FCC is slow to catch up on stuff like that![]()
@GusGorman Transactions via ham may not be legal...![]()
@Sterling Hughes Jr. good advice![]()
@Kevin - absolutely agree, but try to sell that to a kid who has never "suffered" from a day with Internet in his or her life. They won't believe something like that is even possible.![]()
I wonder if a copper water heating coil for a concrete rocket stove could function as an ultra low tech inductor in a 3rd world CW rig.![]()
Nobody is making a profit off the transactions. You're basically sending a message, but it's digitally signed![]()
@Dean Yes, EMCOMM was kind of pushed out to all as a big enticer to bring people in. It’s interesting, but with first responders communication methods today it is less powerful than it used to be. In general, following the “self-supported” communication push I have been going on giving people the knowledge to do this on their own I feel has better capability to sticking with the newcomer. That is why I like events like Summits on The Air and Parks on The Air. Also, I find make a distribution between EMCOMM and Radio Prepping is important too.
![]()
@Dan Twedt you said 'coil', so I think 'yes'; lol![]()
@KI6NAZ Josh - I think I found a "solution" to helping with the RF Problem, but don't want to promote it here in this chat. Could I email you later? I'd love your thoughts.![]()

I'm going old school lol![]()

@Andy C yes absolutely hoshnasi@gmail.com![]()
Hi Josh![]()
Crude but effective. I get 300bps on it![]()
Hi!![]()
separate acoustic cups are good too--radio shack used to sell.![]()
And so pastel...![]()
EMCOMM Case in point: The wife was deployed to South Dakota with Team Rubicon to a large native reservation trying to inventory for flood control and repair. The systems they brought with were limited due to the CLOUD nature of the "Disaster Application" used (Palantir). When I read over the stuff included in these applications, it s the same stuff we use in WinLink for document sharing during quarterly disaster drills. Re-invent the wheel, but expect the wheel to have access to network full time? It's irritating to me - seeing how reliant local emergency services are on digital solutions and collapse when the power goes out. -_- This is actually why I got into HAM so I could at least fall back to something before being forced to use smoke signals. ;)![]()
To go back to SDR a bit. Here was the byproduct of a 3d printed antenna I made and some copper plumbing last night.![]()
![]()
![]()
i wish ham radio organizations would market the phrase "volunteer communications" instead of "public service" because we also do things like supporting bike races, parades, auto rallys, etc.![]()
@GusGorman - I love the coupler!![]()
300 baud is real time readable... I like.![]()
@Sterling Mann yes![]()
I made a "BBS server" using Asterisk, PJSIP client, and minimodem![]()
Is that NOAA? or maybe METEOR?![]()
NOAA![]()
damN! I wish I could get that good of quality out of my SatNOGs![]()
APT?![]()
Nice grab from the WX Sat! - AD7C![]()
I should point out that leveraging the Raspberry Pi into ham radio has been awesome. My current VHF packet radio station is using a Pi 4 and its awesome.![]()
err, not APT?![]()
KI6NAZ I don't remember how to reply just to you. Can you send me a note about the video? I do not know what VLA is. Thanks I am interested in building a global map of the electromagnetic field potential. It would cover roughly from microHertz to MegaHertz for the slowly varying parts of the field, and then all the individual frequency power variations. Only been looking at groups since last summer.
![]()
Been wanting to try Wx sat image grabs for a while now.![]()
@RichardCollins That might be a bit beyond me. My tracking of RFI has been mainly to find find nasty RFI generators and kill them :D![]()
The Russian periodically send slow scan still images from the ISS. It is good fun to capture them![]()
KM4ACK has a good series on YouTube about Raspberry Pi for ham radio![]()
@KI6NAZ Josh can you please say something about the RPiTX. I think it is a viable method if used properly.![]()
morgan! still having issues?? :(![]()
There's also Chinese cubesats sending lowres pictures from the orbit![]()
KM4ACK is the ham radio Raspberry Pi Guru![]()
Tracking radiosondes, scavenger hunt style. That might get kids involved![]()
Yes we don't like RFI it's the enemy![]()
@Corey Shields Not so much, but I have yet to pull an image like above![]()
I can reliably pull APT though![]()
Coming from a digital attitude (and in keeping with the topic of 'making ham relevant now'), I think the restrictions on encryption are hobbling. I do very much appreciate that the essence of ham is open-ness, and that encryption seems to run against that openness, but I think that these restrictions should be relaxed in some way. I think such relaxation will get a lot more folks interested in being able to set up interesting and novel hardware/software.![]()
Eric and Josh, thanks for sharing your EMCOMM thoughts![]()
these days the issues are power/network up the tower![]()
Much of our local community is very vocally up in arms about 5G cell antenna rollouts... Could be another ham opening somehow.![]()
I will say with the changing interests of people, the sake of doing ham radio to make contacts has dwindled some. It more or less seems that people are looking to ham radio to solve logistics problems with the projects. Like longer comms over that of license free modes like FRS, etc. If you can adapt ham radio into what people are interested in, it seems to do very well.![]()
@ziggurat29 - Just curious, where do you see the rules against encryption hindering?![]()
I think the real problem with encryptiong is verifying if an encrypted transmission on amateur radio is actually following the rules.![]()
Encryption works against Spread Spectrum for example.![]()
the problem @ziggurat29 is that how do we know who is transmitting is a licensed ham if its encrypted?![]()
@Sterling Mann indeed!![]()
you cant tell if it's a business stealing the spectrum, or a ham opening a ham radio forum webpage over AREDN![]()
I think that the prohibition on encryption is part of the reason that countries all over the world allow amatuer radio. No secret messages![]()
That is one of the issue Winlink is facing. It’s great for transmitting data, but due to encoding, its hard to be considered “in the open”Hack Chat Transcript, Part 1 02/05/2020 at 21:03 • 0 comments

@Lazer.Coh3n Even a simple scope is a big improvement over no scope, but get the best you can afford and keep it a long time.![]()
Hello alll! Kc2frm here, from forest grove, or.![]()
Will the chat and earlier comments be archived? I'm new to the chat but didn't see a way to upvote/react to the many amazing observations.![]()

Tell her I am sorry! 😅![]()
I wonder how many hams are on hackaday and what % of accounts they are.![]()
you should have your wife meet his wife!![]()
Hi everyone, welcome to the Hack Chat! Looks like we've got quite a lot of interest in our topic today, Keeping Ham Radio Relevant. Let's welcome @KI6NAZ Josh to the Chat and get started!![]()
Hi all!![]()
Josh, can you tell a little about your background and maybe your ham journey too?![]()
Welcome, @KI6NAZ Josh . Thank you for all you do for.![]()
Sure, I’m a SW engineering in SoCal. As part of a project I was on my first Elmer recommended I get my license back in 07’. Which got me started. Before that I was introduced to ham radio via the Boy Scouts.![]()
Since then I have basically just kept learning about radio following what interested me in the hobby. There is a lot to learn out there in radio.![]()
Boy Scouts used to be a great feeder for ham. I hope they still do it.![]()
Um, still is.![]()
https://www.scouting.org/jota/ ^![]()
It is my understanding the merit badge for radio has changed a lot. I will be learning more as my son just started in scouting.![]()
Awesome, good to know![]()
I assume the "J" in "JOTA" stands for jamborees?![]()
yes![]()
Jamborees On The Air![]()
Yes, the yearly scouting campout event.![]()
Correct, it's the "travel free jamboree"![]()
heh cool, is that like 'calling into' a jamboree?![]()
Speaking of camping out, liked the SOTA campout from November on your channel, @KI6NAZ Josh![]()
Yes, one of the big things that pushed me to go from Technician to General was access to the HF bands to work Summits On The Air. A radio event where we hike to the top of mountains and make contents for points. I held an overnight campout on a summit last November.![]()
it was fun and refreshing! I'm glad i got to go![]()
(Speaking of Elmers...IMHO "Elmer-ing" is going to be #1 for keeping ham relevant!)![]()
What antennas and mode do most SOTA participants use?![]()
We had about ten people camp out with us and all those wanted to got on the air. Hi Sterling! Sterling was one of the out of towners that joined us.![]()
contents = contacts![]()
I know some are concerned that amateur radio isn't attracting a lot of youth. Are there some other events that are youth focused other than scouting?![]()
@Dan Twedt however a lot of people have been turned off even at the word "elmer" in favor of "mentor" since times have changed![]()
YOTA, School Club Roundup, etc![]()
Generally, people use 20 meter and 40 meter dipoles. But End-Fed Half Wave antennas are also very popular.![]()
STEM is youth-focused.![]()
That video came out just before Supercon in Pasadena. I'm sure it was actually some time before, but when I first saw it I felt like I missed the chance since I was right there.![]()
@cqw4olv https://ham-yota.com, https://youthontheair.org, https://yarc.world, http://yacht.younghams.org/ are some youth orgs![]()
Thank you Sterling![]()
I'll have to check my kids school and see if they bring anyone in for the ham side of STEM![]()
Boys and Girls clubs are usually open to adults presenting educational stuff. (Mentor is a better word than Elmer, agree)![]()
Here in my part of the USA, there are so many interests for scout to be involve in, electronics and amateur radio, are pretty low on the totem pole. The local ham club I belong to has several log time scouting leadh Hopefully this chay profuces great suggestions![]()
The nice thing about the campout is that the camp site is on the summit.![]()
The worldwide December YOTA event seemed very successful: https://events.ham-yota.com/![]()
Hey all![]()
Decades ago I was an urban 4H member of the Electric Club. It may be useful to reach out to rural clubs as those youth may not have the Internet as a distraction.![]()
Thanks Josh. Do SOTA ops tend to be on SSB or FT8 or CW?![]()
SSB/CW most often due to weight of a laptop is a bit much![]()
I’ve noticed that younger people and those new to radio find it interesting to build tape measure yagi antennas and learn the process of direction finding. It’s a good small group activity. Beacons can be purchased cheaply, or just have a ham in a bunch calling out to test the antennas.![]()
@Dean It seems a lot of SOTA activators use CW (Morse code). However, most of the Youtubers that do SOTA vids are on phone (ssb). Digital modes like FT8 are beginning to see some use.![]()
CW is great since it “goes further” than voice on our lower powered QRP radios that are easy to hike with.![]()
for communication it's hard to compete with cell phones. Youth are always texting now days is there a ham alternative that would have any advantage.![]()
I am really interested in CW. Is it really true that can reach long distance with CW ?![]()
(Those tape measure yagis ... great display of imagination-capturing upcycling)![]()
I'm finding it's a lot easier to learn CW than i thought before I started. two weeks on https://lcwo.net/ and I have almost all the characters learned.About Us Contact Hackaday.io Give Feedback Terms of Use Privacy Policy Hackaday API
