Using SDC contest module with a non TCI Transceiver

[roger dixon]

I appreciate that this isn't documented, searches have not revealed any solutions, and that it may be impossible!!

However, I have managed by using the RadioSync module from ExpertSDR3 as a CAT->TCI converter and Thetis as a headless TCI Server to get frequency and mode synchronisation between my transceiver and the SDC contest module.

But, I really wanted to use this setup for digital modes.  Using the setup described above, I have taken the receive audio from the transceiver through Audio Repeater and a VAC channel and fed it into RadioSync to combine it into the TCI "stream".  When I start a digital modem in SDC it goes "Wait TCI" and connects and then hangs at "Wait Start".  Searches imply that this "could" be due to a lack of audio?

I'm now stuck at the brick wall!!

I'd be interested in any ideas.  Even a confirmation of "no it can't be done" would move me away from the brick wall!

Thetis only supports part of the TCI protocol. This is sufficient for SDC-Skimmers, but not for SDC-DIGI.

Hi Yuri

Thanks for the prompt response - that explains why I'm failing!

As a long shot, I guess that you are not aware of a fully fledged headless TCI server that would work in this role?
