Having used my Elecraft K3 on WSPR for 6 months I decided I needed something cheaper.
I got a PIC-EL and got it going but was frustrated by a lack of an output when its transmitting a signal (needed to key a PA) and the DDS60 drift.
I have written up my solutions at http://g4fre.com/wspr.htm.
It includes details of how to GPS lock a DDS60
