There you go Joe! The man with all the answers! That sounds like the exact situation you have!
Good work on that info! Now I'll have to go back and see what the deal was with the duplexer we had here!

This section was not included in the original -O release of the manual but is definitely in newer manuals such as the -C version. The MSR2000 duplexer family consists of several 2 and 4 cavity models covering the frequency range from 406-520 MHz. The same TRN9041A cavities are used in all of the models, thus the mechanical construction of the cavities should not be a factor in your issue. Different antenna and interconnect cable sets are used for each of the three frequency ranges: 406-430 MHz, 430-470 MHz, and 470-520 MHz. The 4 cavity T4085A models operate at T-R spacings of greater than 3 MHz whereas the T5002A models are configured for separations between 2 and 3 MHz. These use a different set of coupling loops than the T4085A. The maximum input power specification for these duplexers is 250 Watts. ---------------------------------------------------------- --- In Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com, "Joe Burkleo" <joeburk...@...> wrote: "I have a Motorola 4 can duplexer out of a UHF MSR2000 series radio that is the pass/notch style. ...
