Hi Eric, Thanks for the info! I have converted a number of micors over the year and this DVP unit seems interesting. Luckily I have all the modules, but no channel elements, (based on the fed agency, I can see why)... While visiting the Hara Arena this weekend, I'll be looking for some CE's around the 164-166 range for testing. BTW does a DVP unit still take K1005, K1007 elements? I HAVE NOT TAKEN THE GOLDEN SCREWDRIVER TO IT!! Not even to peer inside, what will I find, PL or DPL? Thanks again!

I acquired several Micor DVP (Digital Voice Protection) stations that were removed from Government service, and have some experience converting them to clear voice operation. The primary problem to confront is that the backplane and the station control module are different from the unencrypted Micor stations. A DVP station will have a TLN5979 backplane interconnect board, while a normal station uses a TLN5644 backplane. The DVP station control module (SCM) is a TLN5970, which will not work with the TLN5644 backplane. The normal Micor SCM is a TLN4635, which will not work with the TLN5979 backplane. The bottom line here is that you must use the proper SCM with the backplane you have installed in the station. If you intend to control your Micor station with an aftermarket controller, you probably can make the appropriate connections to the backplane and do without the majority of the plug-in modules. Just be aware that the audio path is different between the DVP and non-DVP backplanes, so the jumpers will be different. The manual you need for your station is 6881036E40 which, unfortunately, is no longer available from Motorola. However, I have a virgin copy of that manual, and am in the process of scanning it into PDF for posting on the RBTIP site. There is already a wealth of information about converting a commercial-split Micor repeater to the 2m band, on the Repeater-Builder site. I am cross-posting this response on that list so that others can help you with the conversion. 73, Eric Lemmon WB6FLY ************************************** See what's free at http://www.aol.com.
