[Elecraft] XTAL FILTERS

Perry,

One clarification - the BFO used for transmit is always the one associated
with FL1 for whatever mode you are set for - and on SSB the OPx filter is
in-line for transmit (to do its sideband 'stripping task'), so for proper
SSB operation, you must have the SSB FL1 set to OPx.  On CW, the transmit
signal does not pass through any of the filters, but the BFO frequency
setting for the FL1 CW filter determines the actual signal frequency.
