Was just curious as to if folks have gotten Notch cavities to work ok with a 600khz split. Have 4 in Rx leg & 4 in TX leg. According to the analyzer, each bank has a >90dB notch. Double shielded cable throughout (RG-9).
Just about pulled all my hair out over the last couple of weeks, and still have desense issues. Even tried another repeater, just to see if it was still there, & yep it is. (was actually a bit worse than the Quantar, but it uses cheesy cables for RX (TKR-720)). Did find something interesting inside the Quantar tho, the RX cable that screws into the RX filter housing had a problem. They use a crimped Mini-UHF, and the section that got crimped actually rotated freely around the piece that has the center conductor in it. Nice rotatable cable, but don't think that it was intended to do that! Soldered the two together. Thanks, Tim W5FN
