Picked up a home built linear with 2 of the above pills. It doesn't work
and I've replaced both pills. Obviously its hard to troubleshoot it
without a schematic but just on the off chance someone may have
experience with something akin to this what else should i look for?
ground appears ok as well as ant center conductor isn't shorted to ground.

Any relays in it?

Can you draw a schematic and try to go from there?

Those are VHF rated transistors. Does it have the traditional
BB matching xformers or is it TRF circuits?

no xformers on the board. Excuse my ignorance but what is a TRF circuit?

Yeah there is a relay. I thought about that but there isn't any
identifying marks to tell me what it is. I cant come up with a schematic
but when i get my Sony Mavica working I will post a pic on my web site.
Sorry to be so oblique but this thing is a mystery.
BTW what is the Jets priority in the draft? Trade down and get more picks?

Tuned Radio Frequency.

The input and output circuits are fixed in one small range.
Capacitors and inductors only have certain values at certain
frequencies. At others, the match is very poor.

Maybe the amp is designed for another frequency.

Amps with broadband matching transformers will work over
serveral decades of range. Most active devices will output
more at lower frequencies.

It was designed for 11 meters as I have used it with great success. It
would xmit the roger beep but no audio.

If they can't get Bush, trade down. I would dump Abraham for more picks. And get

If it transmits the roger beep then its not the amp. Sounds like the radio
has a modulation problem.

Go hump your crackhead slut, druggie boy. All that needs to be done to

fine...it proves that you are a tard.

yep, praying that he dies, like with moparholick. Much more likely with

was kicked out of his parents' home. An overdose or a drug induced
shooting or accident would be neat to hear about, I think. Gotta get
place of burial so I can take a video of me ****ing on the grave and
put it on a web page.

The radio works fine. In fact one of the frequent posters on this ng
(other than myself obviously) now uses it. Its definitely the amp.

JJ said he was intruiged by the Jets, right before he took the Fish job. Woody
is not concerned about the team. He just wants a stadium.

Since Walt Michaels was coach, the Jets have only hired one established head
coach, which was Parcells. Every other coach was a damn assistant, usually an
unproven one.

This team needs great talent evaluators, like JJ or Vermiel. We have a ****
scouting system.

Belichick was an assistant at the time, and a failure in Cleveland. He was a

All Brady. I have not seen a poised QB like that since Montana. Not flashy, but
just poised. Ice water in his veins. If not for him, they win none of the 3 SB.
