I finally found my old relay box used for keying my amp. I did not find the
paper sheet that came with it showing the connections. Three connections
must be made, but there are five ports. I have hooked it up in what I
consider to be the logical way, but my radio immediately returns to receive
when keyed. I seem to remember a trick (alternate hook up) but do not wish
to damage the radio via experimenting. I'm kind of goofy these days due to
medications, so I don't trust myself to make the connections by intuition.
I'm using an Ameritron AL-80A amplifier and a Yaesu FT-890/AT rig.

If someone could make a .jpg of this manual and email it to me via
, I would appreciate it very, very much. Thanks.

Or you can follow this?
Relay box marked "TX" goes to amp relay terminal that keys the amp.
Relay box "red" cable connects to 13.8vdc on rig, "Blue" cable
connects to PPT line on rig.
Hope this helps?

That is how I have it hooked up and is what isn't working. Thanks.

Some radios like the FT-757GX have a "Linear switch" on the back that
needs to be OFF on a non qsk amp.
It is really a simple device, it needs 13.8 volts to activate the
relay, a ptt line sends this 13.8vdc to that internal relay, causing
it to close thus closing the relay line to the amp.
If these situations are satisfied, it should work unless a wire is
open, relay coil bad, etc!
Does the amp key up if you short out the relay line terminal on the
back of
the amp? I had a small microswitch in a cassette box with a wire
coming out. This wire had a RCA male plug & I used it to test all my
amps without even connecting it to a transceiver.

You might be on to something, Rich. I'll check for the switch on the back of
the rig.

Ed, NM2K

If I remember correctly the switch on the FT 890 is internal. Do you have
your Manual? Look through the manual it will tell you where the switch is.

The manual is here "somewhere". I haven't seen it since we moved from NJ to
GA over ten years ago, though I do not doubt that it made it here with us.

I was running this combo a few years ago and I do not remember resetting a
switch inside of the rig.

Since your post, I have received a jpg of the original manual for the
FRB-757 and that has irrefutably answered all my questions. Thanks to
everyone for your help. This has been a very pleasant exchange/experience.
