[Elecraft] CW reception with 3 peaks on PX3

[Fred Jensen]

A distinct possibility.  For those that have a P3/PX3/SDR Panadapter and 
can hear WWV on several of its frequencies, compare the spectra of the 
2.5 and 20 MHz transmissions with those of the 5, 10, and 15 MHz ones. 
The 2.5 and 20 MHz transmitters are low level modulated followed by 
linear amplifier chains.  The others are plate modulated Class C.  The 
difference is striking.
