K3 and Ten Tec Titain 465 hook up

[John McBee-2]

I have just purchased an Ten Tec Titan 425 amplifier and was wondering
the best way to hook it to my K3?  I would like to be able to use QSK
with the amp too.  Just don't want to mess anything up, so thought I
would ask here first.

Thanks in advanced for any suggestions..

I have it working using non-qsk, using key out of k3 to key in on titan
amp.  My question still is how to hook up for qsk operation with k3?


Tnx

John

I've been using Titans with my K3s for years. Works great. The Titan is
a nice amp.

All it needs is an RCA-RCA cable from the K3 amp key out to the PTT in
of the Titan. QSK works fine, but if you work a LOT of CW, it's possible
to wear out the main T/R relay. No problem, they're easy to find,
reasonably priced, and not difficult to change. I've done it a couple of
times in ten years. It's a vacuum relay, mounted on a small board right
behind the output coax connector. The stock relay is a Kilovac or
Jennings; most of us use exact replacements by Gigavac. They have a
special discount for hams.

Schematics are on my website. Scroll down.  k9yc.com/publish.htm
