[Hackrf-dev] phantom broadcasts.... help!

In SDR# this is what everyone sees.

After you click on the play/start button in SDR#  then click on the gear
wheel (the configuration button) and increase your LNA gain to
16/24/32dB and your VGA gain to 16-40dB (only adjustable when active).
Since you live near some very strong RF sources you probably should
never enable the all frequency pre-"Amp" (unless you want to do some
soldering). (see:

If the sample rate is set to 16 then 106.1 shows again at 122.1. Still have not been able to receive anything but broadcast fm. But I have found repeating "noise" throughout all bands again repeating based on sample rate
