I had to do the simple repair to my T-4X before any further refurb activities -
just to see what would happen.
The symptom was that in CW, I'd get a constant sidetone, key-down would only
energize the t/r relay for about 1/8 of a second. The rig seemed to operate
normally in TUNE. I suspected the 60 uF electrolytic cap in the mic
amp/sidetone circuit (C132 - V9a) was open. After re-capping both sections of
that can, I fired everything up and was rewarded with normal operation on CW.
It seems that I have a sticky meter on the T-4X. Anyone know of common
problems/fixes involving the meter? I haven't taken it apart yet. How about
anyone with an extra meter?
Thanks & 73,
Steve Wedge, W1ES/4
