This is not a complete technical reference. W2GLDFeb 5, udplexer There was some problem connecting to server. It is important to verify that any unit has the proper length harness cables for the frequencies to which it will be tuned, as most duplexers will not meet their published specifications with the wrong cables or the wrong length cables. Doing so involves a fair amount of time and work, including total overhaul of each cavity, custom manufacturing of the correct length loops, capacitor duplwxer, and the building of a new frame for the expanded 6-cavity set, not to mention final tuning and performance testing.

The tower owner could tell that the site and utility right-of-way had just been cut, and he and the deputy finally made contact with the equipment operator who admitted he had struck the guy hardware, causing the tower collapse. This capacitor had failed, causing the set set to be taken out of service. All sales are final. Please contact Rodney Renwich at After disassembly of the old cavities, one of the many steps in the overhaul and conversion process involves getting the tuning plungers back in good.

Interested parties, please email me directly at: Well worth the investment of time, money, and energy. This unit was sent to EMR Corp in November and checked out top to bottom, factory tuned to my frequency, paperwork will be provided to the purchaser.

Depending on your budget, location, skills, and available resources, the following options are available for converting a set to a -B model: Herein lies the catch: This guide will be updated periodically as additional information becomes available.

However, it is always advisable to check the unit’s specifications for more information. Models that appear to be suitable for operation on amateur radio frequencies and at typical “ham split” frequency seperation are identified in the list below by HAM after the model number. It is also bowing and leaning very badly. This really is an excellent duplexer for a CM repeater.

We have been monitoring the status of a tower in a community south of Opelika which was supposed to have been taken down a while back. Basic specifications are given for each unit. If anyone has a translation list or chart even just a celwxve model numbers we’d love to offer it here.

Note that we highly emphasize the soldering skills issue, here, because the precision trimmer capacitors used in these duplexers are extremely sensitive to heat — including too much heat during soldering.
