Hans Summers has a new beacon kit that allows full "stand alone" (no PC needed) WSPR beaconing. It is available for just £17.50 with a low pass filter for any particular band plus £14 for the high sensitivity GPS module and patch antenna. I believe power out is around 150mW but this can be increased. As I understand it, it means, for example, a 10m WSPR TX beacon that does NOT need a PC can be made for under £40 even building a separate PA and putting it into a nice box. The unit also does other modes like QRSS and HELL.

I shall have to build one to free up the FT817.
