Hi Bill and all,

Thanks for sharing this, Bill! It gave me the inspiration for a "week-end
project"!

I have done a wspr beacon with Xylo (you remember Xylo :) ?) followed by a DDS
60.

It's working nicely on a dummy load for the moment, waiting to add a small amp.
before going on the air!

The bad thing, is that I cannot use the boot-prom on Xylo to make a stand-alone
beacon, the PC must always be there and running :((.

It was really fun to discover wspr, thanks!

73,
Roland, F8CHK
