[Elecraft] [Elecraft_K3] Who said anything about removing diversity? That would *never* happen...

[Wayne Burdick]

In diversity mode, the main and sub RX synthesizers are guaranteed to be phase-locked to each other if the crystal filters selected for main and sub both have exactly the same frequency offset. The offset for all 8-pole filters is 0.00. The offset for 5-pole filters varies, and can be ordered in matched sets for main/sub.

There's a lot of confusion out there regarding linking and diversity and the advantage of diversity and the importance of the two receivers to be phase locked and not a hz apart or even a half hz apart. Some think just because the two VFO's show the same readout they are in diversity.
