Doug, Although I have never seen one, I do know that Motorola made some full-duplex Mitrek radios- but a Mitrek repeater is a new one on me. Is this unit actually a repeater, that is, does it retransmit any signal it receives? Or is it simply able to receive on one frequency while transmitting on another? If the latter, it is not a repeater per se, but simply a full-duplex radio used in a public-safety application with a handset.
One method I often use to track down a service manual for oddball equipment like this, is to look at the channel elements to learn what frequencies were used. I then contact the seller to learn the history of the radio, and perhaps where in the country it was used. A search of the FCC Land Mobile Radio database sometimes reveals what licensee(s) used those frequencies in that area. Finally, if I'm lucky so far, I can sometimes contact the radio shop for that entity and talk them out of the service manual that might still be on a shelf or filed away. I always offer to send a check up front, for more than the cost of postage, to make it worthwhile to unload a manual that is no longer needed. Even if the shop won't part with the manual, just knowing the complete part number of the document is important information. Above all, I never ask anyone to "just make a copy" of a manual, because that might tie someone up at a copier or scanner for an hour or more, and the pages that result are often difficult to make any sense of unless they are taped together. Maybe if it only is a few pages, but anything over that goes to a graphics shop for scanning or copying. Although the result is a complete and high-quality reproduction, the total cost (including two round trips to the graphics shop) might be three or four times the cost of an original manual- which sometimes is still available! But, I digress... I looked up the your model number in my cross-reference manual, without finding a listing. Perhaps one of the list's Mitrek specialists can provide some insight into this unusual radio...? 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of n3dab Sent: Saturday, March 25, 2006 8:46 AM To: [email protected] Subject: [Repeater-Builder] Info wanted on Mitrek VHF rptr. 73's to the Group The following info appears on a MITREK VHF Mobile repeater. This is a factory (Motorola) built product, NOT an after market modified mobile radio. Can anyone provide any information or documentation on this repeater ? Local searches thru Motorola shops have produced nothing. On the ID plate: Prim. Pwr. 12v Motorola Canada Ltd. Doc. No. 109191038X MITREK Type JJA Watt 2-10 Mod. No. MX23JJA1106BAZ Ser. No. 533PKN1018 Motorola Inc. Made in USA On chasis behind handle: HUD1052CPR On the PC bd. near Rcvr.elements: HLD4082BPR On frame near Tx elements: HLD1002BPR On Controller/PL bd.: TKN9539BAZ On PA bd.: HLD4124APR and TLD5591BAZ Label on top cover reads: " Mobile Communications" and has a "AGT" logo. Probably installed by the service shop. The Rcvr is fed thru the SO239 on the front of the Chasis, the Xmtr is fed out a SO239 on the left rear of the heat sink casting and the recess for it was part of the casting process. This repeater appears to function with the standard control head and cable, though I don't have the original but have had it bench tested for operation. TIA for any and all help Doug N3DAB Yahoo!
