[Elecraft] KAT500/K3 VFO tracking

[Wayne Burdick]

Hi all,

At Dayton I spoke to a few KAT500 owners who were not aware of the latest KAT500-related firmware change to the K3, so I thought I'd mention it again. The new VFO tracking feature allows the KAT500's L-network to be updated as you tune the K3's VFO. We handle this through the control cable (the "auxBus" line, specifically).

This feature is in the current K3 production firmware release, rev. 4.83.
