S-Meter is now working better and RX sensitivity is better after poking and
tighting. I think the relay or fuse lamp socket was not making good
contact. Tightened a bunch of screws.
S-Meter only goes to half scale in XMIT. I found this problem on and R4b
and found what I did on it a few years

Nope! Entirely different circuit. The S-Meter in the T-R4C is also the ALC (transmit AVC)
indicator. It will read 'upscale' in transmit showing the ALC is operating. Adjust GAIN control
while speaking until meter kicks up slightly for maximum output.
