[TenTec] [connect toa "AL 811 Amp."

[Rick - DJ0IP / NJ0IP]

Clarity:  In the paragraph where I wrote, "if you don't hear it clicking,
that's a good indication"...
I meant that it is a good indication that SOMETHING IS WRONG IN THE CORSAIR.

Sri, that bit wasn't clear, first pass.

Hal,

Do you plan to run CW or SSB or both?

The AMP Key line from the linear should connect to the EXT T/R Jack on the
Corsair.
With the radio connected to the amp (coax and all), and with the amp in
operate position, without keying the transmitter, remove the cable from the
EXT T/R jack and tap the center pin against the chassis of the Corsair.
This should cause the amp to key up and you will clearly hear the amp's T/R
relay click.

If it is not doing this, then you have a bad cable or there is something
wrong with the amp.

If it does key, then maybe the transceiver's Amp keying relay is not keying.
There could be a blown transistor (Q10), which is the open collector
transistor that keys the Corsair's relay, but it could also be something
else.

Sometimes people who do not run an amp are disturbed by the clicking of this
relay so they go inside the radio, onto the control board and open up a wire
to disable it.  If you are running barefoot, this causes no problem.  But if
you want to run an amp, then you must re-connect whatever they disconnected.

Maybe the previous owner intentionally disabled this relay because he ran
barefoot and did not like the noise.
You'll have to check that.  If you don't hear it clicking, that's a good
indication.  But to be sure, you need to check for continuity between the
center pin of the EXT T/R jack and ground.

Do this with an Ohm meter, but BEFORE doing anything, turn the RF Power and
MIC gain all the way down.
Then connect an ohm meter and without speaking into the mic, simply key the
mic.  This should cause the relay to switch and the center contact of EXT
T/R to short to ground.  If it is not doing this, something is wrong in the
relay circuit on the control board.

Gud luk and let us know what you find.

I have a corsair and a paragon xceivers.
I want to connect it to the amp. I tried the ways suggested in the manuals,
but no go.
Has anyone done this and can tell me how?


loop forward to your experience.

I tried to contact Jerry directly but the email bounced. 
Rather than sending snail-mail, does anyone have this fore-mentioned doc
(word file) they can send me directly? 
The last item is available on the web, but I can't find the first two.

Please contact me at  my call  @ hotmail.com

I have a recently acquired 540 I'd like to restore.

Thanks,

Bill W1PA
