The FM station is like 96.4, the repeater is 146.700 and the packet station is yet to be determined, but somewhere in the packet sub band 144.9 - 145.9. Thanks for all the information. I'll start looking in the archives.

You'll only need one bandpass cavity. You don't need a circulator on the packet radio. Unless you worried about it causing an earmod mix to interfere with the repeater. What frequencies are exactly involved?

If you look in the archives of this site there have been discussions on how to build them in the past. I believe the repeater builder site may have documentation as well.?

I have some bandpass cavities that will be tuned to the packet frequency, this FM Broadcast site is a 100kW site. What's involved with the tuned stub ? Can you direct me at some reading ? Much appreciated

Mod the radio so you can put one on the TX section. Depending on where antenna is you may get RX overload and may need to put a tuned stub on the RX side to notch out the FM station.?

Hey Folks, Long time listener first time poster. I have a situation where I would like to install a Packet station at a repeater site that is also an FM broadcast site. The repeater has an RF circulator with dummy load installed to keep FM Broadcast out of the TX side of the repeater. Is there anything that I can do to protect the packet radio ? Thanks for any and all suggestions and direction.
