The SL-30 has an internal diplexer, and the 430 does not. I am thinking of using a Mini Circuits ZFSC-2-1 splitter (5-500 MHz), available on eBay, to split the signal. One output would go to the SL-30. The other would go to a diplexer and into the VOR and GS inputs of the 430. Does anyone have a better way of doing this? Thanks for the help.
