I tried this afternoon, the first identifiable Amateur radio signal comes from DI2AM, a museum ship in Rostock. The signal has a nice S/N of about 20dB, and given the distance of somewhere between 150 and 200km it is not very surprising to receive it.
Not bad for a very portable setup : EeePC, Sony SW-100 RX and a wire of about 20m length.
Just tested with the built-in ferrite antenna of the RX : The signal is now just visible and barely readable. The wire antenna does its work. Back to the wire antenna.
The Very Experimental Portable Grabber has been om 600m.
Tests with frame antennas and external ferrite antennas could become interesting.
