I have WSJTX working, and I can see decoded messages. What I don't see on my 6400M is the bandwidth the radio uses on WSPR mode. What should I have it set to?

    Thank you, Mike. I was overthinking it. Everything is working.

    Can you explain more. Are you asking internet bandwidth, receive bandwidth or transmit bandwidth?

    I'm sorry. I meant the RX bandwidth. As far as I can tell, the WSJTX application does not set the RX bandwidth. Being narrow-banded, would you want the DSP RX filters set to 100 to 300 Hz? I am new to the WSJTX application and WSPR modes.

    Just leave the radio at 3000 Hz since the WSPR transmissions vary all around that normal RX bandwidth. The audio filters in WSPR are very very tight and they will take care of the rest.
