400 Mhz Motorola trunking questions
Hi All,
Long time scanner............., trunking virgin. Using Uniden BC785D without the digital card and am using ARC250pro and IDtracker software for computer control. I have done a normal search and logged the repeater frequencies in the designated trunking band for my area for two days and have come up with 10 frequencies including a couple of "birdie" channels (control?) that seem to be used. Sometimes I hear both sides of a conversation, other times just one. I'm struggling to get these to trunk in my scanner. I have chosen "Motorola type II uhf" as the system for the bank I am having difficulty trying to figure out the "base frequency" (lowest logged?), and the offset. (I know the step is 12.5khz) I have loaded them into bank 1, and set the band & frequencies as "trunk", but when I push scan I hear nothing, when I switch over to search there is activity) Also, how do I figure out the ID's ? (Id tracker just comes up with the frequencies) Any "un-gobbledeegook" advice appreciated. Also....Any New Zealand scanners lurking here?? -- Cheers Southern Kiwi Word of wisdom from high in the mountains....you know...like a Guru...but not as old....or mystic......or wise....or high... |

You will have difficulty decoding these trunking systems on 400MHz in New Zealand because the trunking system used is MPT1327. Because this system is not extensively used in the USA, there has been no commercial imperative to develop or build scanning receivers capable of decoding this trunking system. There are a limited number of EDACS systems in main centres in the 800MHz band but they do not have the same saturation as the MPT1327 trunking system which is marketed by the radio telephone outlet of our favourite telephone company. |

Only one required with Trunksniffer and also ftrunk has one scanner option
