Don,
Does that do pep?
Can you warm something up on the thermocouple?
No, it reads RMS feedline current in amps. Working into a dummy load of
known resistance, watts output can be calculated by Ohm's law. On the real
antenna, I just use it to ind

I just bought a Heathkit SA-2060A tuner, with meters built in, at a
recent hamfest.
I currently use a Heathkit SA-2060 tuner, on my 75m full-wave loop, fed
with 450-ohm ladder line.

What if they come around and say they are sure you had a few peaks over
1600 watts?
Have you EVER heard of a ham getting a citation over the p.e.p. rule, in all
the years since Johnny Johnston and his henchmen ramrodded that rule into
Part 97?

The Best measurement I ever got was using a dummy load of know resistive
accuracy. I used a new "Cantenna" from heath kit. I said "new" because if
over heated once they can change resistance. The older one seemed to be
better.

There may be a manual on BAMA. If not, quite likely you can locate a
schematic indicating the part numbers you need. I feel sure you'd be
safe with just about any diode in the 1N60/1N34 category.

No one has said anything to me running 100w, and 4:1 asymetrical
positive-to-negative ratio peaks in the last 4 years.
I am sure they are just waiting

If I could find out the diode type, I could replace them,
the inductor looks to be a match with another one
(forward/reflected?).
It's a small potted thing, almost looks like a cross
between a resistor and a small electrolytic cap.
I don't know how you would calibrate it for average and pep,

I use a scope, plate current and plate voltage meters.
Final efficiency is typically 75% - so, 1500v @ 200mA = 300w DC input is
close to 225w carrier output.
If you don't use a tuner, and know that your antenna is resonant
This is just a guess, but a lot of older watt meters used 1N60 diodes.
The inductor is most likely in the 250 - 275 uh range.

It is not a true peak meter but there is a formula that derives it in the
