K3 Main and Sub BFO's

Roger Crofts
Following the recent discissions of optimum CW pitch, I wondered if the brain might be better able to discriminate the wanted signal from close-in QRM by inverting the sideband to one ear. Only the wanted signal would have the same pitch in both ears.
I set-up the main and sub receivers to a separation of double the pitch frequency and then linked the VFOs. So far so good. Then I inverted the sideband on the sub receiver. But alas, the sideband on the main receiver inverted at the same time. Even using "b Set" I could not get the BFOs on the main and sub to operate independently. They do operate independently in SSB, but not apparently in CW. Am I missing something?

Only one CW normal/reverse indication is saved for both main and sub, on the theory that for a given band, the operator is probably going to want one or the other but not both. Still, if this particular part of the Twilight Zone is of further interest, I'll put it on the wish-list. But it's a complex change, unfortunately.
