Time for another radio post. Yesterday me and SA2KNG made an attempt at holding a conversation (QSO) on the 23cm band. The plan was to use HackRF to do narrowband FM modulation/demodulation on my end, with KNG using proven equipment on his end. We only got as far as him possibly detecting a carrier from my location, which might have been the HackRF’s local oscillator. Future attempts may yield more success..
