Yeasu FT920 Digirig and FlRig

,
1

Howdy,

I have a Digirig RS-232 and new cables for the FT-920 and it works great with WSJT-X when used directly!

Baud rate 4800, Data Bits and Stop Bits default, no handshake, PTT Method of RTS, Mode Data/Pkt, and Split Operation Fake It.

I am having trouble with FlRig.

PTT button initiates transmit, but does not terminate transmit when unselected (turns yellow only for a moment).

Using WSJT-X with FlRig as the radio obtains CAT control, but PTT function and frequency changes result in aberrant frequencies; they may be multiplied or divided by 10.

I want to be able to use FlRig for other purposes such as Winlink, FlDigi, etc, where FlRig cat control and PTT function make it much easier.

Attached are the FlRig configs.

PTT lockup may be a sign of Radio Frequency Interference (RFI.) Please look at the section in the Guide Troubleshooting Digital Modes – digirig .

I have the Yeasu FT-920 HF radio. Can you please provide all the settings you are inputting into WSJT-X to get your radio and digirig to work.

Also Are you using VSPE to share the com port for CAT control and Serial communication? If so what settings do you have on the digirig com port?

Thank you

See the second paragraph in my post for WSJTX Settings. Never heard of VSPE.

Wouldn’t this happen in other apps too? I’m now able to use WSJTX as well as FlDigi directly with no issues. I’m thinking it’s an issue in FlRig settings somewhere?

I was able to get my FT-920 setup with the digirig. I appreciate your help with the settings. I have CAT control and PTT working on DATA mode. WSJT-X FT8 works well.

I have having a difficult time getting WSJT-X WSPR mode to work. If you have any helpful information that would be great.

Thank you
