[TenTec] Orion's break in

[Ron Castro]

I have experienced the same problem on my Orion II, and it's definitely the
T/R relay.  I got a new one from TT and installed it a fraction of an inch
above the circuit board and wrapped it in silicone sealing material and it
quieted down, but later started to exhibit some 'squirrelly' problems during
contests where it appeared to stick for second or so when going from
transmit to receive.  I went back to the old relay, but I think the problem
is that some of the relays TT used made noise and some didn't.  The problem
I had during contests may have been due to the relay heating up because the
silicone material kept the heat in.

In my case, I am absolutely positive.  We're splitting hairs here as to what
to call the noise.  It's a mechanical noise and as N4UC said, the noise is
heard on the relay break, not the make.  I can prove that by tuning the
external keyer speed way down and sending a single long dash.  And it IS
annoying.  I've owned dozens of rigs capable of QSK and non-QSK operation
and while some of the others showed relay noise like this in QSK mode, NONE
made any noise in non-QSK mode except at the beginning and end of a
transmission.  This sounds exacly like the noise one would hear from a
larger reed relay that is not mechanically isolated from a circuit board.

As time allows, I'll dig into my Orion II and solve this.

operates with every character, is so noisy I can hear it in the next room
when the sidetone is turned off. I wouldn't characterize it as "clacking"
though, more like chirping. And it makes the noise when the relay relaxes,
not on the make. VERY annoying! I'll bet that's what he's talking about.
