Re: RD16HHF1 in the uBITX #ubitx

Re: ubitx receive audio troubleshooting
If using an external speaker, make sure it has a stereo plug (not a mono one). I mistakenly plugged a mono plug external speaker in and it squealed.

I tried 7222 and it sounded like there was a station way down in the mud. I also tried to listen for myself on a number of SDR radios around the country and nothing. I will try back later. Ed W0OIC
