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

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.

Hi Ed --
I was surprised to see the entry here on RadioBanter showing some of the info from my website on repairing Bird slugs. I just wanted to mention that my website is not at all defunct but is still very active at:

www.hayseed.net/~jpk5lad/

and that particular part quoted was from:

http://www.hayseed.net/~jpk5lad/BIRD.../birdslug1.htm

If anyone is interested there's a good bit more info on links off the same URL as above. They've come from others who know a lot more than me who have seen my article and sent me the additional good stuff. I've reproduced it on my website with their permission.

I'm glad this information is of some value to others. That makes it all worthwhile.

Do a Google search on the subject. You will find plenty of
information on this if you use the right search words. I suspect the
resistor or diode in the slugs are bad. Here is one ham's (now defunct)
website info I got off a Google cache:

Inside Those Bird Slugs

Did you ever end up with or do you now have a dead Bird slug? No, not
the kind you have in your shotgun but the kind which fits inside the Bird
Wattmeter series which makes them so valuable. Have you ever wondered
what was inside them? Well, I had one which I purchased at a hamfest
("Is it working OK?" "Sure, it is. I used it right before I headed
down here to the hamfest.") I foolishly believed the seller but once I
tested it at home, I realized that I had a dead slug. I have since found
a way to test them before paying the money and I'll be glad to share that
info later.

buncha other stuff.....................

Had I been able to verify the contents and inner make-up of the Bird slug
earlier, that is, if I could have read what you just read, I would have
started the repairs much sooner. It may be that I was just lucky and
attempting this project again on a different dud slug would have resulted
in a much different outcome. I was, however, very pleased with the final
result on this particular attempt. If you attempt the same, I hope you
have similar success because, as we all know, "A Bird in the hand
is............ oh, never mind....." ----- K5LAD

your web pages on Bird Slugs. I have re-bookmarked them.

OK Ed --
Boy, I'm slow at answering things, aren't I? Glad you found it again.
