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".

Subject: Topband: Single antenna port xcvr but want to employ separate receive
antenna
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.
