John:
I noticed the same thing and tried encapsulating the relay with that
material that's like Coax Seal. It quieted the relay completely, but I
noticed that when I ran in CW contests, after a few hours the relay would
stick for a second in the TX position, so I changed out the relay with a new
one from TT, but this time I left the leads on it an didn't press it all the
way down into the circuit board. I can still hear it, but it's not as loud
as when the radio was new.
Hope that helps!

Subject: [TenTec] Orion II T/R Relay Noise Reduction Ideas?
Hi Folks....
No, my relay noise is NOT loud......at all.
But, I'm spoiled. My first original Orion was perfectly quiet in QSK
mode. I could place my ear on the top cover and nothing, nada.
I have had two Orion II's and both have an audible relay click when using
QSK. It is not annoying or loud, but I'd like to improve on it, if
reasonably possible.
The same T/R relay has been used in both Orion models. It is made
exclusively for TT by US Relays and Technology Inc. It is tubular and
hard wired to the rear PCB. TT claims no change has been made in the
relay or mounting method.
Has anyone played with this, and been successful? If so, please share
your method.
Thanks, and 73..........John W4II
