The CASE
// Reused old Pelican rugged case, used while ago for environmental monitoring project. Case is adapted with 10mm okume lacked plywood. (salvaged after the kitchen reconstruction) Construction consist of base on the bottom of the case, fit with velcro strips prepared for custom configuration of used parts and equipment. Extension top "table" now used for optional notebook PC, can be set in at last 3 fixed positons. (see pictures)
At the moment within the case:
HARDWARE
-SDR LimeNET micro / RPI CM3 8MB
// procured for another project within initial campaign on Crowd Supply
-ICOM PCR-1000 modified for 10,7 IF out working like pre-selector for Lime
// one of first useful general coverage receiver with PC user interface only, was reviewed in the July 1998 issue of QST magazine. RS232 to USB interface must be used
-moRFeus mixer & signal generator
// mixing 85-10,7 =>74,3 MHz to get better signal, LimeNET RX have significant
drop in sensitivity bellow 30 MHz. Spec. of mixer within moRFreus are from 30 MHz and up, but on 10 MHz results are still good enough. In future, this component may be replaced with new made of some DBM like SRA-1 and 50 MHz osc.
-Siemens SX763 LAN/WAN WiFi working like DHCP server and LAN
// old house ADSL WAN router with WiFi AP, still useful for this project.
-AC/DC Power supply for each unit + (soon) internal 24 V DC supply.
