Hello,
during the ARRL CW Contest I found that SDC Skimmer can't decode any station.
I am using the same setup as the PRO2 but SDC isn't decoding anything.
The Nano samplerate is fixed at 48KHz and SDC IQ samplerate is 48KHz as well. IQ stream is coming from "TCI Only".
Can you confirm it?

Hi Enzo
I had this problem this afternoon with sdc and Sunsdr2 Pro. No decoding but for CW stations which were outside the band plan. For the others no problem?

Hi Jean-Marie,

thank you very much for your kind reply. Please can you post your samplerate settings with I/Q control picture?
Anyway I was in the usual Region 2 CW bandplan, i can't explay this issue.

Guys, I wonder if it works for you.

We installed Colibri and SDC for a friend, and SDC Skimmer is not copying anything from the Colibri Nano. Visually we can see morse code on the screen, and see some garbage text appearing in SDC Skimmer, but pure garbage, it will not copy callsigns... It has nothing to do with frequency, station we try to decode are in the CW portion of the band.

I had a similar issue a year or so ago, then I had to go back to an ancient version of SDC to get skimmer work again. I am not sure if it would work now as my station is now disassembled.

Hi,
Unfortunately it's a known issue, by both our programmer and Yuri Pavlov.
We don't know the source of the issue, code base is the same for all devices, but we'll definitely find it and fix it.

Hello,

I suspect it is a Windows firewall problem. I found that if you have installed two different versions of EESDR on the same PC, they are both referenced as ExpertSDR2 in the "Incoming rules" panel.
Sometimes, deleting all the ExpertSDR2 and restarting the program, can solve the problem. Of course, when Windows firewall asks for EESDR permissions, give it them all.

Thanks Roman. The more I think about it the more I have the recollection that I had to roll back the ExpertSDR version not SDC. Dont you happen to know what the last version supporting SDC Skimmer was?
