I would like to publicly thank

ldn0l

for sharing information I was not aware of. Apparently you can already transmit on the raspberry pi without using an external module. (source) http://www.rtl-sdr.com/transmitting-fm-am-ssb-sstv-and-fsq-with-just-a-raspberry-pi/

This will come in handy once I decide to make an all-in-one encasement for the project.

Thank you!
