[Elecraft] KAT500 operation?

[Phil Hystad]

Have you verified that this automatic feature is enabled in your K3?

Here is what you need to do on the K3:

To enable automatic KAT500 VFO tracking:
      - Locate the K3's CONFIG:KAT3 menu entry,
      - Tap '1' until you see "KAT500Y". (The other selection is "KAT500N", the default, which turns VFO tracking off.)
