Ive been dabbling with sdr sharp for a month or so now using an RTL2832U R820T2 TCXO+BIAS T+HF v3. Ive had good success with picking up local broadcast such as police, fire, air and such, so i know that its set up and working properly. I have been trying to pick up ham, and have been able to receive one local qso, but thats it so far. I assume I have not heard any other distant ham transmissions for lack of a proper antenna, but anyway my question is, when i try to use ( Q branch) all I ever pick up is am radio broadcast (local) on any given freq, some stations are fro 60 miles away or better, so I dont think the signal is so strong that they over power any other type of reception. Is there a reasoning behind this? perhaps the wrong settings? thanks for any responses.
