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.
