Roger,

I have copied CW signals from the UK in the 1mW range.
So 500+ km sould be possible in CW.

73, Rik  ON7YD - OR7T

Quoting Roger Lapthorn <[email protected]>:

In the evenings I'm surprised just how good my reports are from F6CNI some 418kms away near Paris. Last night my 1mW ERP was being received at 0dB S/N on WSPR and already he's given me -3dB again tonight.

If signals are this strong by sky wave, how much further could I reasonably expect to get? SM6BHZ and GM4SLV have heard me (850-950kms), but can I (reasonably) expect much further? What is the typical attenuation on each ground reflection for multiple hops over water and over land?

BTW, still not on 136kHz yet.

73s
Roger G3XBM
