So what do you do to Q12 on a TRC-422A?
Q20 on a TRC-428?

Lil'Yeshua · Aug 21, 2013

Does anybody know what to do with Q20 on a Realistic TRC-428?

VaHam · Feb 24, 2018

TRC-483 modulation increase; cut R57. No pots to adjust. Should end up with PEP of 12-15 watts.

Josh380 · Feb 1, 2020

What to do with adjustments for trc-482?
Realistic TRC482: {L304, L305, L306, L307, Q201}

I know you can also cut d208(audio limiter)

Cutlass327 · Apr 23, 2020

Realistic TRC465: {L26, VR5-AMC, VR6-ALC, VR10-AM PWR}

What is the difference between AMC and ALC?

Low_Boy · Apr 23, 2020

AMC AM modulation.
ALC is for SSB.

Cutlass327 · Apr 23, 2020

Thank you.

That says L26, but is is beside the finals and filled with wax. Is it part of the TVI/harmonics filtering that gives ghost watts or is it a legit adjustment?

9C1Driver · Apr 23, 2020

The ALC and AMC are legit adjustments. What ever part is the TVI trap stay off that.

Cutlass327 · Apr 23, 2020

Yeah, I wasn't sure if that is part of the trap it not. It's a plastic piece with wire wound around, and a ferrite screw inside for
adjustment. Being waxed like a couple cans and the trap "bare wire" windings people love to spread, I figure is is part of the trap.

What is the difference between AMC and ALC?

AMC = Automatic Modulation Control (adjust to no more than 100% modulation). Most radios power supplies and mod transformers can not even hit 100% well without severe distortion, ie splatter.
ALC = Automatic Level Control (You need a scope to adjust properly on SSB)
Note: Simple power meters are totally insufficient for ANY adjustments, including RF power out/dead carrier.

Cutlass327 · Apr 24, 2020

Yeah, I have to drag out my scope... It got put away for lack of space, but I'm going to need it again now.
