I think I am safe with my 3mW erp.... at least it reaches
Biggleswade.

Incidentally after we worked yesterday Dave G3WCB sent me a wav
recording of the QSO and an Argo screen shot. Our signals sounded
very similar with him and it was nice to listen to my keying at a
distance. As Dave commented to me the Argo shot shows that my VXO tx
is stable apart from a very slow, hardly visible, drift. Your TX has
a noticeable downward drift of around 5Hz at the start of each over.
I think you use a VFO?

I can send you these (converted to a .mp3 and much smaller) if you
are interested Chris.
