Hi Markus

Never mind these comments form "Mr. G"

I've been away from the MF for some time, but will start up again now=
.
I've got me a small X1M radio. It has an output of about 4.5 W from
100KHz to 30MHz. I will build me a power (15W-20W) and will try to be
operating in a short while.

 It is a different approach (coherent correlation) to achieve differe=
nt aims. There are benefits (like good detection sensitivity, open so=
urce code), and disadvantages (like no decoding of a-priori unknown s=
equences).
