Rob,

I re-read the french regulations. They say: under 28 MHz: 500w pep; 28 
to 29.7 MHz: 250w pep; 144 MHz and up: 120w pep whichever mode you are 
using. Many are outlaw. To be closer to legallity we can use AMC 
(Amplitude Modulation Compending) as used in broadcast transmitters here 
in France.

I don't know about DL land but I never heard a german network, I often 
hear G stations around 3615 kHz.
