A while ago I replaced my SDRv3 with a RSPdx and boy it was a big win. I'm in Shoreline WA about 13 miles north of Downtown Seattle, I'm presently receiving KAWS CSN International on 89.1 Mhz from Boise Idaho 494 miles. I've got longer DX's before but only with Sporadic E skip. There is some slow moderate fading but not bad. It's noisy but intelligable. Given there is a mountain range inbetween this is quite a catch. The mountains make troppo unlikely, the lack of serious fading makes sporadic E unlikely. So I have no idea what mode of propagation this is.
@spacedream can only transmit to people if they have a receiver on the same frequency/technology.
here was an interesting piece about radio hacking:

(no actual hacks in there, but a report about it)
then time will come people will figured out, surely. no need even talk about.
but yeh, maybe its time to diy sky scaner to get sats and freqs for sky wifi from ilon(/etc). something inside me telling me its can be used legally even without pay.

read that, and get back to us when you've digested it.
@Robert Dinse, sure. i understand.
but soon we will be using complete new technologies, quantum ones. imagine quantum dirac radio communications ;) no matter of distance always with no delay. we got already access to neutrino. anyone can play with it now as diy at home. you sure you still want spend time to fix your old dial-up modem?
