Another ham friend and me both have 100 w slugs for 100-250 Mhz. (100c).
Both are bad. Tests were made on three different Bird meters and a 3rd
slug known to be good.

On all 3 meters inputting 100 w, the good slug showed 100 watts while
the two bad ones showed 70 w and 60 w respectively. Pretty high odds
that we both would have faulty slugs eh?

So the questions a what happened to make them go bad, and can they
be reasonably repaired by the Bird Corporation? Although we will
be calling Bird personnel next week I thought I would throw out the
question here.

Last but not least, any good 100w 100-250 Mhz slugs out there for sale?

You did test them into a good dummy load ? Anyway if you peel back the
label there is an adjusting screw. YOu may be able to adjust that to match
the known good slug. That adjustment is a small pot.

Thanks, did not know about that.

Harrrray for curiosity!!!!
Just a FYI you might check out the Directional coupler project from ARRL
Handbook 1974 page 636.
This is the homebrew version of the Brand Name Bird. But it can give a good
understanding of what's happening.
If you have time and a friend to help calibrate your project. Works great.
Lasts long time.

After you build one.... it's just like most other electronic gear... Buying
one made for how ever much money is
just convenience. Well I retired now... more time than money hi hi
