Yes, WSPR-15 is possible with the U3. I may have to add a fan to the 
PA, though, as I have never run a 15 minute continuous transmission 
at full power before.

The U3 is an amazing and cheap piece of kit but it will take me some 
time to build - it took me a whole afternoon just to read the 
instructions. I really hate construction (love operating, antennas 
and propagation instead), so it will have to be divided into many 
small tasks while I calm down in between! 

A bonus is that I have bought the GPS unit that goes with it, so I 
will have a source of 1PPS for future EbNaut reception.

I will announce when the WSPR is working.
