Re: Convince me to stay with SDRPlay (or the opposite)

Suggestion: you can do the comparison by yourself using a "spyserver" (see AirSpy website for reference and guidance). (be patient, sometimes those devices are off line, unreachable etc. etc. but worth while a try...) I gave it a try. Do not expect miracles. I'm a proud owner of a "vi...

Re: simple but good wire antenna

tuning shift (save)

When I start a listening session I click on the waterfall some ten kHz away from the center (L.O.)
in order to avoid the well known central spike.
Unfortunately I have to do this each time I run SDRuno. Is it possible to save this displacement from run to run?
Thank you in advance.

Re: Antenna feed line length question

I live on the second floor of a five floors concrete building. Antennas are on the roof and I have no less than 30 meters of RG6-like coax from the local tv/sat shop. I have a lot of fun from 77 k (time signal) to 260 M (milsat pirates) With this kind of rig sensitivity is not an issue. The problem ...
