[TenTec] Omni 6+ mute?

[Rick - DJ0IP / NJ0IP]

Barry, I was thinking about this some more.

I don't have the schematic here (ok, I could download it I guess).
Anyway, once you determine "where" the "T" and "R" signals are generated, either on a Control Board like in the old days, or on the CPU board, what you can do is interrupt the "T" signal where it exits this board. This will prevent the OM6 from going into TX mode. 

Then you can place the rig in TX as you have already tried and you "should not" get any of the side affects you were experiencing.

If you need to mute the RX too, then you will have to tie the TX line of the transceiver doing the transmitting into the R line of the OM6.  Specifically have the TX line of the transmitting rig key an external relay that disables the RX line of the Omni VI, while having the TX line of the OM6 permanently disabled as described above.  In any case you're going to need a shovel to get in there and dig.

Hope to wrk U in the contest anyway.

I'm only on with the Eagle Barefoot and a dipole this year.
I'm still searching for my darn CPU (parallel port) to rig connection for keying the CW.
Haven't seen it since 2 years ago back in Oklahoma!
I may end up keying the contest by hand.
Well I guess I could wire up another cable in a pinch.

Rick, DJ0IP

Thanks but have you actually tried it?

My mute jack does NOT mute the receiver when grounded.

Thanks for all the responses.  Like Rick suggests, I'm going to have
to tear into things which isn't going to happen before this weekend's
contest.
