In light of the fact that his power supply might have been capable of
remote sensing and in view of your statement: "I thought the OP would
like a solution utilizing what he mentioned he had on hand." It seems
to me that your "familiarity" with remote sensing supplies would, at
the very least, brought forth the question of his power supply having
that capability and, if it did, a suggestion to use that capability.
I figured if he had a variable supply, he would not be
so concerned about voltage drop. I tend to assume,
until shown otherwise, that people have a modicum of
intelligence and initiative. So it would not occur to me
to ask if he thought of turning his supply up, although
I gave him a subtle hint that such might be possible.
As for the OP's possible possession of a supply with
remote sensing, I tried to concentrate on what he
claimed to have and give him a workable method
within that constraint. A long list of questions about
what else he might have did not seem time effective
for him or me. I spent a short time considering what
supply he had and decided it was likely something
simple, probably hobbiest grade, since he could
not trust its current meter. Then I decided not to
worry about it and take its output as fixed.
If you want to label those judgements as "ignorance",
"lack of familiarity", "rush to judgement", or anything
else from your panoply, be my guest and I hope you
get as much out of it as I do.
In context, my "knew of" clearly refers to my
knowledge or alleged lack thereof. This last
point is getting to be a real sidetrack.
You, though, knowing that such an option might
have been available didn't bring it up either.
That's right, for reasons stated.

He probably shouldn't, but that's not what you advised him to do, you
sent him on some wild goose chase to measure this and that and
calculate this and that, when all you had to tell him was to monitor
the voltage at the input of the radio and crank the supply up to make
that voltage go to 7.5V when he was transmitting, LOL!
HaHa. What makes you so sure he had a variable
supply? And that it could be set higher than he had
already set it? The guy comes here wondering what
to do about a few 100mV of supply drop, knows
enough electronics to recognize some issues that
concern him, and I should start asking him if he has
thought about doing the most obvious things that
anybody with the sense he already exhibits would
not need to come here for? LOL indeed! Thanks,
but no thanks. I'll leave the insulting in the capable
hands of you, Fred, and all your invisible friends.
You also wrote:
"You could also put a lower shunt resistor across
your ammeter and calibrate the combination."
which is one of the stupidest things I've ever read. Do you know why
or would you like me to explain it to you while typing through fits of
laughter?
Ok, I'll bite. (But I must say, your stupidity guage
has some strange attributes given our recent chat! ;^)
Be sure you do not let any lack of imagination affect
your notion of how stupid that idea actually is.

That may well be true for your stuff. It just goes
to show that your experience, or anybody's, is
limited and does not constrain reality. Maybe,
since those resistors (when they exist) are inside
the supply, you just never noticed them.

"Chicanery" is a little much, John. Nobody was
hurt or even sorry it happened. I am sorry that
this is not obvious to you, and that you have to
leap to that kind of unwarranted conclusion.
I should caw here about how few seconds that would
take to find on your own, (assuming you could remember
how to spell my name for a few moments), but seeing as
how you've been such a helper with Google: US 4656416
