Jeff,

I just looked at the instruction manual for the IC-7300 and it seems to confirm your observations. To be clear, I do not own a IC-7300.

I also don’t see anyway to get to a wide bandwidth IQ data stream. If someone who actual owns one finds otherwise, I would like to know about it.

Sounds interesting! A tech night might be a nice place to discuss/build the mini beam.

I’ll kick this off with a comment and question about using the IC-7300 with WSJT-X.

The IC-7300 doesn’t work smoothly with WSJT-X and maybe someone know how to make it better.

1. How to set the digital mode bandwidth to 3 KHz or more.
2. How switch the Tx audio source from internal USB sound card to Microphone more quickly

The IC-7300 has a data mode, but it is not compatible with WSJT-X because it only support a maximum of 1200 Hz of bandwidth.  WSJT-X needs 2700 Hz for JT-65A and about 4 KHz to include the JT-9 modes. That means the radio has to use the regular SSB modes with the filter set to 3 KHz when running with WSJT-X.

The IC-7300 has a menu to select the source of TX audio for “data” mode or for “data off” mode.  But, since the data mode doesn’t work with WSJT-X, the user has to switch between taking TX audio from the internal USB sound card and the microphone.

Can anyone think of a way to improve this operation?
