[Elecraft] [K3] AM-S VFO Tracking

[Pierfrancesco Caci]

It looks like the VFO tracking function for synchronous AM is not
described in either the K3 Owner's manual or Cady's book. Or at least
I couldn't find it when searching the PDF files for "track" and "spot".

For those wondering, there's a description about it in the firmware
release notes (hfwnotes.rtf), look for the notes about "MCU 3.57 / DSP
2.45, 11-7-2009" in that file.
