Nice and quiet here in SoFl, I require permission to keep it that way. any licensed users welcome, but let me add your information and call sign to my log first. Simple as that.

My mentality has been changed over the last 6 months or so. I went from having private portable GMRS repeaters to not having any as I really no longer have the need for the service on a family basis (now it is simply another go to and talk service for me) as I've been moving everything family/business related over to VHF P25 primary and DMR UHF secondary. So now if I'm going to put up a GMRS repeater...I'll put up an open repeater and just leave it as is. Scott, nice to see the Saber love (even this morning on Ops Who Use). For those who don't know, Scott is a Saber whore who has probably forgotten more about the Saber than most of us will ever know.

I usually utilize a UHF, rf generating device

I seem to recall that T1504 was a four bandpass/reject cavity duplex filter. It may have been sold as a kit of parts. But in any event depending upon the frequency band you got a set of critical length interconnect cables and a "T" connector. The duplexer is band pass with reject notch filters. The band pass is wider than the reject notch so after first tuning band pass, then tuning reject, you could fine tune the reject with the pass knobs. That is how I did it and they worked well. The trick was that the screws on the slotted reject loop had to be almost tight so they made reliable connection and then I would "rap" the screws one direction or the other in the slot to tune the notch. A couple Excelite nut drivers were the ideal tools to move the knurled nut. Use one as a "hammer" and the other as a "chisel" and tap their plastic heads together to move the nut just enough. Then hand tighten,
