New open-source project transforms Android phones into ham radio transceivers
Homebrew
I’m doing a bit of experimenting…
with cubesat and a homebrew circular polarised antenna.
I’ll let you know how I get on.
Baluns !
I do like an end fed long wire !

I have it on good authority that if you connect a piece of wire to pin 4 of the gpio connector (length of wire determined by frequency of course) your Pi can transmit.
This Github link will take you to the software and the video in the previous post shows you how to install and run it on a Raspberry Pi
Have fun !
