Thetis & SDC, does not Tx

[Roberto Bracconi]

Good morning everyone,
I have both Sunsdr2 pro and Hermes, I would like to use the "contest" function with both.
Obviously everything is perfect with Sun, with Hermes I receive perfectly, I have a working skimmer, but when I try to go to TX it doesn't transmit anything, in fact, it doesn't even switch to transmission.
I'm using the TCI protocol, while for the Skimmer I'm using Audio Iq+Tci.
I'm definitely doing something wrong or forgetting something.
Has anyone solved the problem?
Thank you

Thetis TCI doesn't support Audio only rig control 

You have to use vac for thetis audio.

Ritchie hasn't ever applied the audio porting of TCI.

I   know this, in fact I use audio iq+tci  for the skimmer and, as written, everything works well.
I use Vb Cable as a vac
When in the contest function I try to "answer" it does not switch to TX, I have no output power and the radio remains in rx

Only the skimmer part of the TCI protocol is implemented in Thetis. This is not sufficient for SDC-Contest operation.

Thanks Juri. 

Do you have any ideas or suggestions that would allow me to use SDC also with Hermes and Thetis?
Thank you

Roberto,
There is a useful video you can follow from  MW0LGE where he goes through setting up SDC with HL2 & Thetis

Thanks David,
I had seen these instructions before, but they are for receiving only.
I'm looking for a way to use the beautiful SDC also in broadcast, especially during contests, with the specific tab made by Yuri which is fantastic with the sunsdr I have.
Thanks anyway for your interest.
