[Drake] 2NT with a VFO??

[Dave Edwards]

Ed....do you have the link for the kit website...and what model you use?

I may play around again today with multiple VFO's and verify that I can 
reproduce the problem. If I encounter drifting, perhaps I'll look at  the 
VFO output with a counter and see if it drifts while sitting there not 
connected to the 2NT
Thanks....Dave
