After a long hiatus I am revisiting this concept. Turns out wefax reception is very poor when you live in a wooded area so I moved to an area with clear sky. I've been able to record and decode transmissions on my laptop using gqrx and fldigi.
I have been far less successful on openplotter using the same antenna and sdr. The reception is just so much worse! It helped to move the sdr from a usb hub to a directly into the pi. I've also tried using a 3 or so foot dongle cable to get a little distance. I can receive images but they are very poor.
I have yet to get the opencpn plugin to receive anything(by that I mean it returns a lightly staticed white image). I added the direct sample flag to the rtl_fm command under the scheduler tab and set the upconverter offset to 0 since I'm using a v3 rtl-sdr. Is there something else I'm missing?
Thanks!
Perhaps it would help to turn off the ais sdr on the moitessier hat while receiving?
