[Elecraft] IF Out tap and sub RX

[Bill W5WVO]

Clarify for me how the IF Out tap point works with respect to the Main vs. Sub receiver. Is it always connected to the Main receiver? I'm thinking about how it would be to have a panadapter monitoring 6M for Es openings while working, say, 20M CW. If the IF Out tap is only on the Main receiver, then I would have to use the Sub receiver for the ongoing HF work, I guess. This should be no problem, as they are identical... Can you clarify how this actually works? Maybe there are menu configuration settings I don't know about.

Also, please clarify again how the two antenna connectors work with the Main and Sub RX. Can each connector be assigned in the menu to (a) a particular frequency band, and/or (b) a particular RX?
