Jim,
I did the same thing years ago. I modified an old B & W antenna switch,
added a 12 volt relay triggered from the amp out jack.
Even without the switch, 3 panel mount SO-239s, a relay and an enclosure
would be a minimal investment.

Traditionally a "T/R switch" means a switch to be used the other way, to
allow you to move a single antenna between your separate transmitter and
receiver. Ironic that here we are in the 21st century and some of use an
external box to do the reverse function!
To switch between transmit and receive antennas on my rig, I use a small
12V relay keyed via my Ten-Tec Eagle's "amp key" output when I'm on 160.
Every transceiver made in the past 50 years has an amp key line of some
kind. On the Jupiter it's a phono jack labeled "EXT T/R".

Have my vertical working great and have a small Delta-loop low band
receive antenna BUT the Ten Tec Jupiter doesn't have a separate receive
antenna like a K2, for instance (I borrowed a K2 to try out but the
buttons/controls are to small for me to operate as I have a severe case of
peripheral neuropathy, courtesy of Agent Orange).So, I am up and running
and will be in the CQ 160 contest at the end of January but have no means,
currently, of switching rapidly 'tween the top loaded vertical and loop. A
T/R switch won't "do it" for me....so looking at a DX Engineering RTR-1A
but sure don't like the
price!!http://www.dxengineering.com/parts/dxe-rtr-1a
Anyone have an RTR-1 or 1A that is excess to their needs and willing to
sell OR have another idea of how I can employ a separate receive antenna
when I have one antenna port?
Thank you, in advance, for any replies....off line replies work for me.
