[Elecraft] Using the k3 for WSPR

[EricJ]

Yea, it's not relevant to WSPR. The WSPR modes are just USB SSB 
modulated by audio tones. By convention, the VFO frequency is set to the 
bottom edge of the WSPR subband, and your transmit frequency is set by 
the frequency of the audio tone. So everyone is tuned to the same 
frequency and occupy a portion of the same 2 khz upper sideband.

BTW, WSPR is the only mode I have ever used where I was able to work the 
inventor! I kind of missed out on Mr. Vail and Mr. Morse, and doubt they 
every were on the air at all. Likewise, Inever met the inventors of AM 
or SSB. But K1JT appears relatively often on 20m JT65 and JT9.
