[Elecraft] Now that we've covered roofing filters, a Q on sub-receivers

[John Harper]

Imagine my dismay as a submarine veteran at learning that the K3's 
sub-receiver has nothing to do with an AN/WSC-5  ;-)

As I understand it, the main purpose of a sub-rx is to allow diversity 
reception based on the fact that this 2nd receiver would be using a 
different antenna than the main rx, correct? I'm not sure if there are other 
advantages and am curious if that is the case as I ponder which config of a 
K3 to eventually order. If that is the only advantage, I doubt it would be 
necessary or useful for me...if I need that much finessing to copy a 
station, I'll never work him with 100 watts and any antenna I can put up.

I'll probably get a 2nd round of whatever version of K3 I decide on as I am 
(finally! after 23 years) getting transferred back to 5-Land soon. In the 
meantime, it sure is educational reading the posts of some of you who can 
translate and "analogize" some of the options I've never had reason to 
consider before.

Thanks and 73,
