Got a hackrf. Sqeet.

hackrf_transfer -c 127 -f 100000000





hackrf_transfer -r /dev/null -s 20000000

Made  quick little fm transmitter.

Only goes a couple feet, so should be okay wherever you do it.

Also doing it on our ham freqeuncies, so doubly so

fm_transmit.grc

Audio source comes in from the microphone

Gotta resample

Should resample before fm-mod?

When I did, the signal looked better, but deviation from central frequency was way too high. Could low pass, but probably not the way to go

More to come probably
