Amazing ears…

Just spotted this on 10m:

 2011-12-15 13:24 VU2SWS 28.126033 -13 0 MK68gn 0.005  PE4BAS JO33jk 6762  322

That’s amazing this 5mW signal has go into my antenna over a distance of 6762 Km with a again amazing signal of -13dB. It’s hard to believe as I didn’t see my own 0,1W signal spotted by her station, but that can be a lack of internetconnection of course. That brings me to another puzzle at the radiohobby. Signals or propagation seem not always be reciproke. At least not at my station. Overall I receive more then I can transmit even with 100W. This is the case especially on 10m. It happened to me again last ARRL 10m contest. I knew some amateurs (PD1RP) were on a little DXpedition on Texel Isl. using a 2 element moxon in the contest. I could clearly copy them over a distance I think from about 100km. But whatever I tried, they could not hear me. This happens to me once and a while and I don’t know who to blame? Have they got a bad receiver, attenuation on, QRM or QRN? It’s hard to believe but I sometimes think I must have a exceptional quiet QTH as I do not have any QRN/QRM on 10m and a very low noise floor. On the Icom I always have the preamplifier on at this band as I can pull out a lot more stations that way.
