[Elecraft] Linked VFO's -- usage?

[Wayne Burdick]

Hi Dave,

You don't need to use linked VFOs for this purpose. If you've set up a repeater offset on the current band, and have selected +/- rather than simplex (using the ALT switch in FM mode), then transmit will automatically be offset that amount from VFO A no matter where you tune in the band. 

For this reason, you don't need to use VFO B at all when using FM and repeaters with the K3, K3S, or KX3. Hence no need to use VFO linking, SPLIT mode, etc.

73,
