  The DXE RTR-1 is superb in performance, design and construction.  I have in the past built a relay driven unit derive with a Darlington 2N2222 from the H send output on the radio.  i have even in a pinch used the MFJ-1026 Noise and Phasing unit which has a built in relay circuit for power through.  This way I put the RX antenna(s) bank on the "noise antenna" input and turn down the main antenna pot.  This way I also have use of the onboard pre-amp if i need it and noise phasing against the TX antenna.
