AetherSDR and SDC

[Jim Selmi]

Hi Yuri,

Are you familiar with AetherSDR for the Flex radios? It's an amazing Ai app.

I'm using the current v0.8.5. I submitted a bug report, because their TCI server was unable to connect to WSJT via TCI. They pushed out an update this morning and it seems to be working with WSJT, although the developer is seeing some audio issues and is still working on it.

I was able to make a couple of WSJT FT8 QSO's this morning connected via TCI connectivity

I didn't notice audio issues, but I just confirmed connectivity and made a couple quick FT8 QSO's.

TCI CW Skimmers in the SDC v19.06x64 app still doesn't work via TCI. I am able to get CW skimmers to work in SDC using SmartSDR API connectivity.

Have you tried to connect via SDC TCI to AetherSDR TCI?

Thanks for developing SDC. I've been using it for contesting the last few contests and

really like it.

Hi Jim

At the moment, I don't see any signs that IQ stream transmission via TCI is working in AetherSDR.

Be sure you have PC Audio selected in the AetherSDR client.  If you are listening to the radio output audio, there is no stream via TCI.

Thank you Chuck. )))

Audio data is now being received, and there seems to be some kind of transmission as well. However, the sound is distorted, as it appears that AetherSDR is only operating at a 48,000 Hz sampling rate and is not switching to 24,000 Hz, even though it receives the command to do so.

But I haven't been able to get the IQ stream yet. It accepts commands but does not execute them.

I've noticed some improvements in how the TCI-Audio system works. The sampling rate is now correct. However, I'm only receiving data for one slice.

There is also an issue with the consistency of the stream. Delays can reach up to 100 ms.
The SDC stream still isn't receiving the IQ data.
