[Elecraft] Filters OP1,OP2,etc.

[Wayne Burdick]

Hi Alex,

"OP1" means "optional crystal filter #1." While we can imagine multiple
optional filters being installed in a K2, as of now, the only optional
filter is the one on the SSB adapter, so that's what you get with any of
the "OPx" filter selections.

The K2 manual provides suggested SSB and CW filter bandwidths and BFO
frequencies. More detail is provided in the KSB2 manual--use that if you
have the SSB adapter installed.
