Just got back from retuning the cans at the 146.850 machine in muncie. Very interesting. The machine has been pretty limited in range for years, and I expected that the cans would be off, but never how FAR they were off.. If the pass and notch weren't so flat and ragged, I would have though

The phenomenon you are seeing is because the 1/4 wave size at VHF is 3/4 wave at UHF. I believe the hybrid duplexer design uses 2 or 4 notch only cavities. If you haven't drilled holes in the side 2 of the band pass cavitiys I believe they can be converted to notch only by simply removing the 2n

If they are piston trimmers, grab a ICOM for a GE MASTR-II, as long as it is not a low band version. This is a cheap and readily avalible source. But you may have to solder the trimmer in place as I don't think the outer ring on the capacitor is threaded. On 4/12/05, Tom Tishken KD4WOV(laptop

The T-1504 works very well if clean. The notches are difficult to tune perfectly if the inside of the cavity has been exposed to moisture. I have opened up cavities and cleaned with steel wool and coated with light grease and they tune much better. I am not sure if anyone else has had this
