Hello,

I would like to use SKM with SDR Console, using CW Skimmer setup on SDR Console for QO-100 Satellite activities (Contest / Daily).
How is it possible to have SKM compatible with 10 Ghz frequencies?

Example : SDR Console is tuned on 10.489.515.000 Hz.
I haven't found the way get this frequency on SKM.

Any idea?

No reply ?

The issue seems SKM need one more digit (to get 10 Ghz capabilities) 
My Bandplan is updated.
If you play out of band on lower frequencies, no problem…

I hope to get a fix…

I see a problem with RigSync for frequencies above 10 GHz. Wait for an update.

Results of test version v17.3402:
It's starting to work. In the SDR Console to RigSync direction, there are no problems; the correct frequency is read. Between RigSync and SKM Server, the correct frequency appears in the bandmap. So, in RX only, everything is fine.
Now the problem is in the other direction, in the bandmap direction from SKM Server to SDR Console. If you click on the bandmap, the frequency sent to SDR Console is incorrect. In fact, it seems to be the base frequency (or similar) that doesn't take into account the offset entered in SDR Console.
Example: If I click on the bandmap frequency 10489516, the SDR Console changes to 1,899,581,433 Hz (1.899 GHz) instead of 10,489,516,000, which is an offset of approximately 8,589,935 kHz (approximately at the click in the bandmap).
If it helps, in "Converter Definitions" of SDR Console, my RX Offset = 9,749,982,400 and my TX Offset = 8,089,503,600, and in SKM Server, my IQ Offset = -6600 Hz so that the frequency displayed in SDR Console is equal to the frequency in the bandmap.
That's all.

Damien, I fixed the problem and updated the installation file on the website. Please download and install version 17.3402 again.
