This won't work on Orion.
Switching from UCW to LCW will not make any
difference in attenuation of unwanted signals.
Only the audio frequencies will change.
Page 15 of the Orion 565 manual contains an incorrect statement:
"...operator chooses whether the BFO is above
or below the target frequency to minimize QRM..."
The truth is that the BFO will be placed in a different position
(relative to the target and QRM frequencies), which is irrelevant,
but the receiver passband will still be in the same position.
