[Elecraft] K3EXREF and Trimble Thunderbolts

[Wayne Burdick]

No -- Installing a K3EXREF has no impact on VFO use (at any tuning  
rate).

If you adjust REF CAL manually (i.e., with no K3EXREF unit installed),  
you can move the reference in 1-Hz steps, but as Leigh pointed out,  
the steps may not be exactly 1 Hz. This is due to DDS granularity.
