[Elecraft] XV144 LO frequency

[Don Wilhelm]

Bo,

You certainly are welcome to try pulling the crystal frequency with a 
small parallel or series capacitor, but the stability may suffer - I 
have not tried it, this is a theoretical guess.
Remember the crystal in all except the XV50 are overtone crystals - the 
XV50 uses a fundamental mode crystal and can be pulled using normal VXO 
oscillator techniques.
