How accurate are these SWR/Power/Modulation meters for modulation? I am
restoring an old TRC-455. I want to get to 100% or just under. I do have a

I think a lot has to do with the cost of the meter.
Some of the cheapo ones may be as bad as 25% tolerance... while some
of the better ones may be 15% tolerance.
The scope is a much better tool... and easy to visually see 100%. The
scope would probably be more like 2-3% accuracy.

Do I inject a 1 KHz tone right into the mic plug, or do I have to go thru the
mic?
