Hi Joe, Paul,

> the frequency offset is a show= stopper

maybe not. Joe how exactly are you generating the signal, 1= 0 MHz OCXO (with or without GPS?) and a binary-counting DDS? Theoretically.=  

10M / (2^32) * 3551941 =3D 8270.0070925057..

so a= bout 92 uHz high.

73, Markus

Noise is coming f= rom the south west, Joe is on bearing
280. I shifted the beam north to = 310 to reduce the
noise quite a lot (and the signal a bit too) -

= Now in 39.7 uHz

Intrig= uing, but the frequency offset is a show stopper.
