Any input on whether CTCSS or CDCSS/DCS is better for high noise/RFI environments? I was thinking that CTCSS may work slightly better in this situation since it is not a digital format.
I am assisting a client in cleaning up a mess where another vendor installed a VHF Conventional Analog Repeater in a networking closet of a school that is producing a significant amount of noise/RFI in the immediate area of the repeater. I have cleaned it up a little bit with better double shielded coax running between the duplexer and the receiver. However it still isn't performing to the standard I believe it should be. I believe the receiver is partially deaf due to the noise/RFI in the immediate area. The other part to this equation is that the previous vendor used LMR400 as the feed line from the duplexer to the antenna.
The organization didn't anticipate or budget for a really expensive or costly system so I am doing what I can to try and get the repeater to operate at satisfactory performance without starting all over from scratch.
Thoughts/Suggestions/Ideas?
