???? A K3 is a digital radio. There is no balanced modulator for SSB with a balance adjustment. The SSB envelope is directly created (without any carrier or opposite sideband, only digital artifacts) in number stream form by digital programs in firmware. The SSB envelope first emerges, fully formed, at the TX IF, formed from the number stream that is input to the TX Digital to Analog Converter. This is clear in the schematics on the web page.
The closest "carrier" that could have a vestigial output would be the 8 meg conversion frequency that is used to convert the signal from 15 kHz up to the 8 meg filter frequencies. That would be 15 kHz away and suppressed by the ultimate rejection loss of the roofing filter used for TX SSB. It would not be mistaken as an unsupressed carrier, even if it could be heard. What is more likely, is that a 120 Hz or 60 Hz hum is on the audio and getting through. Deadkey SSB, one of these could be mistaken for "unsuppressed carrier". That will require cleaning up the audio wiring or power supply, taking care of pin 1 problems, etc. 73, Guy.
