Update..

Replaced L16 with one out of a parts board. Exact same result in the position of the slug. Shows max at rim level. Instead of using a trimming cap can I use a fixed value cap say 10pf and then tune the slug again?

Found bad AM-VR and replaced it. I now have an adjustable dead key. I set it at 4w and now it swings up to 6-8w with modulation. Able to achieve 80-100% modulation on external meter. AM TX has been resolved.

So for now here is the current status...

AM - RX is good, TX is good. Still no S meter reading on incoming signal. Meter does work. When I key up the internal RF meter shows 7 when I turn the VR to match the external meter nothing happens, like there is a constant voltage on key up.

SSB - receive is better than before after switching out L16 but still no S meter reading on incoming signal.
TX - Still very little power on SSB like 0.5w and only able to achieve 30-40% modulation which is better than when I first started.

I checked all the voltages on the RX to the meter and voltages all match.

I was hoping that with this updated info maybe it would help narrow down the issue. Thank you for the continued help.
