I read somewhere that the 20 MHz xtal could be changed to 19.6608 MHz to move more channels into the ham band and avoid interference with shared "channels".

I only see two xtals on the circuit board: 25.000 and 48.000 MHz.

I have not removed the shield cover.  Is it under the shield?

Any info you can provide on this mod will be appreciated.
