While I do not have the answer to your question, I would like to take it farther.? If I understand the 920 manual, the YF-116A/INRAD #710 filter is required for AM transmission.? So if you put a SSB filter in the second filter position do you sacrifice the ability to transmit on AM?? Will a SSB filter work in the second position?? If you look at Menu number U-69 (CW) and U-70 (AM) they seem pretty specific.? I.E. CW and AM.? Is this indicating that there is no additional post manufacturing SSB filtering available?? Looking at the circuit diagram it lists the CW and AM filter slots.? I am far from knowledgeable on the Yaesu filter schemes.? I know my FT-1000 Mk V has five filter slots.? I believe the FTdx-3000 only has one slot for a CW filter.? I only say this, because I've always been a bit confused on Yaesu's filter options.? I'd love to hear from anyone on the subject.
Take care.? 73 Harrison N1FAM
