I've rebuilt a pile of those duplexers, it is just bench work to disassemble them, clean them and reassemble. Most of my rack mounted stuff is black, and I like that, so I usually spray paint the components of the cans when I have them apart with black gloss spray paint, taping up the holes so no paint gets inside the can. Then I buff and clean the inside of the cans as I reassemble them. I've not ever noticed any change in response after rattle can painting the outside of the cans.
On the same product, does anyone know the specific difference in the 5 mHz spread and the 3 mHz spread versions of these duplexers? I picked one up and the notch appears to be only tunable about 3 megs from the pass frequency, is this a simple change in the notch loop or something? I'd like to use it on a 5 mHz split. 73 N7HQR > So I have been trying to put together and rebuild a bunch of equipment > for the hilltops. Just got another set of Moto T1504 UHF cans.
