Sounds like time to clean connectors. This generally applies to all
radios which are 10+ years old. Never spray anything into the radio!!!
Using a cotton swab such as a Q-Tip, apply contact cleaner to the cotton
swab, unplug one cable, and wipe the male pin(s). The plug in the cable
and unplug it a couple of times to provide wiping action of the female
contacts. Usually this corrects 90% or more of all issues and the radio
is good for another 10+ years.

Hi all... Fault symptom as follows:-
At switch on Omni VI "motor-boating" before locking in then operates normally. Later it
emitted a "drift-like" sound as if going out of lock and again returned to normal.
Some days later after similar to above it drifted off completely then emitted a
permanent low frequency buzzing noise in the LS which remained even when the
Tune button was pressed.
All this time the O6 TX appeared to key and output normally but there was no
sidetone only this buzzing from the LS..
Now all has returned to normal and I cannot pursue but would appreciate
anyone's thoughts or who maybe has experienced same fault condx.
