General troubleshooting for receiving HF signals

Post by ajforrest » Sat Nov 21, 2020 3:00 am

I'm looking for advice on how to go about troubleshooting a reception challenge I'm experiencing in the 3-5 MHz range.

I have the V3 dongle with a dipole antenna and I'm using GQRX on Mac to run it. The dongle works fine in the usual frequency range and I'm able to find, tune and demodulate FM radio let's say but when I switch to HF (hence the dipole) and direct sampling I'm unable to find the signal I want (just noise). This is despite having a known working low-power beacon transmitter in the same room.

How can I improve my chances of finding this signal?

Can you try receive broadcast AM? Please upload a screenshot of your settings, and what you see on the screen when tuned to the beacon frequency.
