[Elecraft] K3 Filter Gain question.

[John Ronan]

Hi,

#2184 was recently fitted with a sub receiver (very nice). It occured  
to me that I never sat down to figure out how best to set the gain  
figures for the filters. I have
Main:
KFL3B-FM
KFL3A-6K
KFL3A-2.7K (-77)
KFL3A-500 (-73)

Sub:
KFL3A-2.7K (-76)
KFL3A-500 (-75)

The handbook suggests 1-2db for 500Hz, and I've seen posts warning  
against using excessive gain. Any suggestions?

Also, using diversity receive on the same antenna, the signal seems  
to 'move' slightly more than once per second between my headphones.   
I assume this is a feature of diversity and the different signal  
paths through the radio, as I've never had a radio with diversity  
receive before.

Regards
de John
