[Elecraft] XV-144 -> redesign = XV-144-2

[Don Wilhelm]

Ron and all,

The XV144 will not tune high enough in the 2m band to send FM.  The 
28MHz IF strip is not wide enough to do that with one Local Oscillator 
crystal.

The K144XV switches crystals to allow the upper half of the 144 MHz band 
to be tuned.

While it is true that the XV144 *could* transmit FM in the lower part of 
the band, that mode is not allowed (at least in the US) on the lower 
portion of the band, so DTMF tones would not be of use.

73,
Don W3FPR
