Can you tell me what tone mode is programmed into memory 1 according to the radio (or other software)?

Okay, I'm guessing maybe it is "EPCS" mode, based on the manual. Chirp can't really support that properly without a lot of work, but mapping it to "TSQL" mode makes sense I think. Here's an updated module for you to test. See LoadingTestModules for details.

In case it wasn't clear, I was hoping for an acknowledgement of the tone mode and testing of the module, if possible. I'm holding up merging this into a release in hopes we can get that ack :)

Hi Dan, sorry for the delayed response. I had tried to just reply to the email alert and that bounced. on membor 1 it is 145.15 using DTCS tone with value 664

Hmm, okay that is not what I expected. Can you configure a DTCS channel in chirp and see what mode the radio thinks it's in?

I can try for the VX-170. If i don't get to it by tomorrow night, I'll be out of town and won't be able to get to this until 4/8.

I also have a Yaesu FT2D with this same channel configured in slot 1 which works just fine

Yeah, it's definitely something with the VX-170. It has DTCS as tone mode 4, your image has tone mode 5 in that slot. So either the driver is wrong about mode 4, or mode 5 is "dtcs plus something else" or something.

I'll hold off until you can confirm, thanks!

hi Dan,
performed the upload of the freq with DCS 664 and radio set the mode to TSQL

...Okay, does that mean TSQL mode doesn't work? It would be very strange to have two values in memory to indicate TSQL mode... Is there another TSQL-like mode in the radio? Perhaps it actually selected TSQL-R (Yaesu calls this REV-TN mode). Or perhaps when you select TSQL in chirp, you get REV-TN on the radio?
