SDRAngel
Posted: Wed Sep 11, 2019 7:22 pm
Hello,
I am new to the forum and ATV; I have a Portsdown RPi and a LimeSDR mini so far. I am using SDRAngel and an Airspy mini for rxing.
Days have been spent trying to get to the bottom of the problem
; that's not a complaint, in fact I have learned a lot more that I would have.
Anyway, I have a simple " fix " for my problem and have attached a screenshot.
The only way I can get a decode is to manually adjust the centre frequency by a few Khz then return it to the original.
Would anyone like to hazard a suggestion on the cause of the " problem " ?
RX PC info - maybe a little old ?
