In its current configuration my kit only pumps out 200mW and I left it running while i went out to a party with the family. On my return I was staggered by the reach on the little kit. The longest distance it was heard was a staggering 6408Km ! all that way with just 200mW of RF..
Here is a map I've downloaded of the plots :
and a list of the stations that heard it. You will notice some frequency fluctuation. I have to box the kit up and think about some stabilisation on the DDS. but hey for its first outing - I'm very happy !
