USB OK, LSB narrow/pinched TX audio

[email protected] All Messages By This Member #406 Good evening! I have an FT-847 that I have had a good while and only used it on VHF (6 and 2 meters mostly, some satellite). The transmit audio sounds FB on upper sideband, but on lower, (75 meters) it sounds terrible.? I have tried to see how to validate the carrier frequency for LSB, but not finding a setting or trimmer that affects the frequency in any way on either sideband. Any suggestions? Thanks Victor

Andrew Lenton All Messages By This Member #410 开云体育 OK The SSB part and FM Path are completely different, There are two PLL’s for upper and low side band, I suspect you LSB PLL is off frequency or out of lock, they both go off to the Balanced modulator: ? The technical supplement will tell you how to check it ? 73 ? Andrew ? ? ? toggle quoted message Show quoted text From: [email protected] [mailto:[email protected]] On Behalf Of vstockma@...
