Dear Yuri,
I noticed also earlier that sometimes some callsigns are not recognized and spotted by the CW skimmer.
It was difficult to catch an adequate example, but now I could.
Now G5O was not written into the SDC Skimmer band map at 7018.4 kHz and neither spotted to the radio, nor to N1MM.
But the callsign was recognized and highlighted in the decode window multiple times, actually more than 20 times.
I don't understand, why it was not sent to the radio/skimmer band map. My skimmer settings are also shown in the video.
See the video here:
