Hi Don et al. Yes indeed the stability is the issue. Tweaking the frequency is a piece of cake.

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. 73, Don W3FPR Bo, OZ2M wrote: > Hi all > > During the Christmas holidays I finally decided to assemble my XV144, and > XV432 too.
