Receive Antenna Interface- DXE-RTR-1 from DX Engineering - http://www.dxengineering.com/pdf/RTR-1-Rev3.pdf
Ameritron AMR-ARB-704 - http://www.ameritron.com/man/pdf/ARB-704.pdf
I also have the AMR-PNP-8M (arb-704 interface cable)
various RCA and stereo and RCA to stero cables.
The ARB-pnp-8m goes from my radio to the 704, easy enough.
Next i think i need to connect the "transmit ground from my radio to the transmit ground of the dxe-rtr-1?
