I am using the following system: openplotter on Raspi 3B with Noelec NESDR receiver and a generic bluetooth gps receiver, opencpn 5.2. Problem is gps signal getting lost when i have sdr vhf activated, or ot seems so.
After initial setup, i added first bluetooth gps dongle via blueman applet and create connection in signal k. In opencpn all ok, gps signal is stable for days. But soon as i add sdr service in signal k connection, gps signal is lost in opencpn, sometimes within minutes. There is nothing wrong with hardware, same works fine under windows, and raspi has enough power. Ais signal is fine, targets are showing, but gps signal dies imediately.
I tried feeding gps signal directly to opencpn via serial connnection, same issue. I had the same somwhow freezing of nmea imput whe monitoring in gpsmon. I did two clean reinstalls, same issue.
