Hi Phil, I do not know why it takes too long to repopulate. Sorry, I had no idea the Colibri was so different from the other EE products.

GM Erik, yesterday evening I have had a help-video-session with Enzo IW7DMH.
There were not much differencies in the settings of my CNano and his rig.
The only parameter changed has been the Skimmer-Samplerate from mine 48000 AUTO to MANUAL 96000 and the PANORAMA
has become filled with all audible Callsigns and the cw-decoder has began to write rows of readable messages.
So guess that the SKIMMER-SAMPLERATE should be put more in evidence in the help files.
Now am just waiting for the CQWPX CW to test my brain's skills and the artificial intelligence of the CNano rig.
tnx agn fer help es 73

OK Phil, thank you for the update. I will emphasise sample rate in the UMA, in a future update, in relation to the Colibri.

Hi,
in the mean time I asked Yuri some clarifications about the counters that are shown in the Skimmer Window.
I sent him the first picture you can see below.
His answer is very clear and can answer some of Phil questions.

...
646 - the number of spots sent.
104 - is the number of decoders.
77 - is active decoders. The remaining 104-77 = 27 are in standby mode. Perhaps station again nachet work at this frequency.
...


In addition, I would suggest to give a look at the IQ control panel. When I started the Remote Desktop session with Phil, the panel was showing a undefined CW region, as you can see in the second picture. I just moved the panadapter background (dragging it with the right button mouse) and it started showing the correct region.
Maybe there is something different in the Colibri nano IQ data stream, but I can't say more about it.

GE Enzo,Erik et All. I come back at the radio-pc-desk tonight, after an afternoon retuning my HF2 vertical for the CQWPX, up&down many times from the roof....
now it PLAYs good music.
About the ColibriNano, switched ON again after the remotesession with Enzo and again no stations , ok on 20mt there were just few ones.
The sample-rates were same as yesterday.
Then moving around the MANUAL\AUTO setting in the SKIMMER_Setup now seems going again. The SETUP likes much the MANUAL setting.
One thing is not clear to me: the IQ\CW window(the one with red&white bars) vs Skimmer-samplerate vs Colibri-samplerate.
More : why a Callsign well strong is decoded in the VFO-A text window but does not compare in the skimmer horizontal running and hence not even in the panorama ?
But comes out in the panorama from the web-cluster telnet ? ...
That's for tonight.

Something is wrong. I have never seen a station decoded in the VFO-A text window that does not come to the panorama - provided that its callsign is decoded the required number of times set. It might not come on the first decode if its not matched in the DTA but on the second decode it surely must. Or else the Colibri is a strange beast that I understand nothing about. Over to you Enzo......

GM Erik, rereading my last post and also yesterday seamed strange to me , but it was so.
My brain + CWGet + SDC-skimmer decoded the callsign (it compared RED in the row, but nothing appeared either in the horizontalpart nor in the PANORAMA.
Anyway I have to do more experience with the ColibriNano+SDC combo + IC8POF's brain ;-))) .
What a best occasion if not a super_field_test than the next CQWPX_CW.
CU ON_AIR next weekend.

Nothing to add Erik. Once the Colibri starts working as expected SDC is the same like the Pro2.
From my experience SDC works very well, and during the contest, I found myself clearing many times the spots in the panadapter simply beacuse they are too much.
Also, in contest like CQ-WW or CQ-WPX and some others I prefer to disable external spotters like dxfun and reversebeacon, simply because "too much informations" ==> "no informations".
