Transatlantic on 136 KHz
Sun, 26 Apr 1998 20:19:21 -0700
I will be listening. No frequency seems very clear here. I have
interference from my computer connected to the DSP engine. I have
intereference from my wife's computer and my daughter's computer (we are a
very computation intensive home), but I am working on it. I am practicing
on beacons. I will try to hear you, but I think I will have to do much
better on my antenna before I really get in the running. Anyway, keep
transmitting, we really care over here, but we have a long way to
go...david,k8mmo (Oakton, VA, USA).
