With the repeater tx at 444.975, the second receiver would only be 25 khz away from the repeater transmit frequency! The duplexer wouldn't pass anything to the receiver at 444.950.

I have a UHF Master 2 repeater (run 30 watts) and a spare UHF receiver. I plan to have one receiver tuned to 449.975, the second to 444.950. I also have a high Q bandpass filter. If I was to run after the duplexor the bandpass filter tuned to 449.9625, (then a low gain preamp) then a tee then 1/4 wave of feedline (take in account velocity factor) to each receiver would this work? Is there a better way to do this? The site is at a commercial broadcast site, antenna is at 300 feet (2 bay folded dipole) and is replacing an exec 2 repeater at the same site, which works quite well. Any ideas or suggestions?
