After analysis of Czech active hams on CW, I got idea to modify script and do world wide overview. I have still data downloaded from RBN.

During first run, I got a lot of bogus callsigns processing raw data. Skimmer is not 100% technology. In example: many KD2xxx were detected as D2xxx, as first letter was lost. I assumed, those errors are usually made when skimmer decoding weak signal.

So, I applied simple filtering, at least 10 readings with signal strength 10+ dB is needed. Number of stations look much real then. Of course, there are still errors, one way could be compare them against QRZ,HAMQTH, etc database, but I think it is waste of resources due low effect.. Another approach is deep checking call / time period / frequency.

In bellow listing:

• counts of unique callsign
• grabbed via RBN in period 10-12/2014
• stations calling CQ on CW
• stations grabbed 10+ with strength 10+ dB
• shown entities are DXCC+WAE
• rows with zeros remained after filtering
• result is indicative!
