Hello = Markus and=20 Paul,

There is much jubilation at this QTH thanks to your = spectra,=20 reports and

Advancing the phase by 16pi was to no = avail,=20 but an XOR between the

I think 4 seconds will be good for symbol length until I = can sync=20 the

A new and better aerial was raised today so things are = looking=20 up.

Thanks to the EbNaut Experts!
