[Elecraft] SSB at something more then 2.2kHz?

[Don Wilhelm]

Frank,

Do you have the KSB2 option installed in that K2?
If so, the SSB FL1 filter should be set to "OP1" instead of "2.2".

If you do have the KSB2 option, look at the board.  First check the 
markings on the crystals
If they are 4913-S you have the new crystals on that board.
Then see if there are capacitors in the CB and CN locations.  If not, 
the width is the newer 2.4kHz, but if you do not have capacitors there, 
you can order the K2SSBCAPKT and change the width to 2.4kHz (or even 
2.6kHz if your BFO range is sufficient).  You must have the 4913-S 
crystals installed to take advantage of that increased filter width.
New KSB2 options come with capacitors for the 2.4kHz width.

73,
Don W3FPR
