I may have had the same issue as you. Elecraft instructed me to listen
to my SSB signal via the monitor, start at 10watts and as you speak
start increasing the power. When you reach 12-15 watts I bet you will
hear your audio become distorted, sounds sort of like RF on your audio.
If not then you have a different issue.
You may want to try that test. For me it require a trip to the factory
for repair.

Elecrafters,
i have 2 K3's, #8862 and #2878.
Listeners using Panorama adapter gear like P3 or sdr radios report
unwanted strong sidebands when #8862 i bought from a friend is in use.
All is fine when #2878 is in use with same settings, power, external
amp, antenna and same mic.
The signal itself inside the ~3khz passband is fine, both K3's sound
about the same , all ok.
One listener said, the problem vanishes, when power is below 12W (only
low power stage in use).
I build a K2 (#2706) and the K3 #2878 myself, so i'm not scared to
take #8862 apart to find the cause.
Where to begin?
TNX.
