[Elecraft] [K3] factory upgrade to K3(s)

[Dave Cole (NK7Z)]

With all the talk about the old and new synthesizers, I dug out my old 
screen captures of some tests I did showing P3 captures as the 
synthesizers were changed from old to new, in two radios, one looking at 
the P3 for changes.  See:

The images are of my P3, showing another radio with both with the old 
synthesizer, then with one radio upgraded, then both radios upgraded. 
There is a very visible change for the better using the new synthesizers.

73s and thanks,
Dave
