[Elecraft] K3 as WSPR transmitter

[Bill Frantz]

I have run FT8, PSK31, and RTTY a lot on my K3. Even before I 
installed the 100W amp card. I have never had any problem with 
the low power amplifier (LPA) with those modes. I have also run 
those modes at 100W with the KPA3 with no problems. I don't 
think you'll have any problems with the 110.6 second WSPR 
transmit sequence.
