[Elecraft] K3

[Lyle Johnson]

> If using an external receiver with K3 is the RX ANT OUT the correct connection to get signal to the external RX?

Yes.

> I see a PHONES connector on rear panel.  If used how does one switch between speaker and headphones?   I like the idea to get MIC and HEADPHONES off the front panel.

Plug in headphones to either the front or rear phones jack and the 
speaker is muted.

> Is the PA circuit breaker readily available if needed?

Yes, it is on the rear panel, part of the fan assembly.

> Can ANT1 and ANT2 be set and stored by band? 

Yes.
