Wow! The windfall makes your club the envy of Hams, worldwide. Congratulations on your enormous collection!
Before the Repeater-Builder crowd can answer some of your questions, perhaps it would be a good idea to ask a few: 1. What are the complete model numbers of your radios, from the label under the battery? 2. What frequencies will you use for a portable repeater? More to the point, what is the separation between TX and RX (which dictates the type of duplexer you can use)? 3. Do you have the detailed service manuals for this equipment? 4. Do you have the software, RIB, and cables to program these radios? Connecting the PTT to the transmit radio is easy, and you can use a cable from a remote speaker-mike to handle that chore. Finding a signal in a portable radio that follows a valid receive signal is more of a challenge, and really requires having a copy of the detailed service manual. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of pe1pme Sent: Sunday, June 14, 2009 3:13 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] building a repeater out of two MTS2000 hand helds Just a week ago the provincial policeforce handed over to our DARES unit (Dutch Amateur Radio Emergency Service)their whole old analog radiosystem, consisting of about 630 Motorola MX 2000 and MT(S)2000 handhelds!!! That was realy fun to receive as you can imagine. Now we like to build, for emergency purposes, some portable repeaters out of two MTS 2000 handhelds. Things like duplexfilters and some kind of repeaterlogic is no problem but connecting them together is something else!! On Batlabs I found the pinout diagram of the accessory cable but I can't figure it out how the handhelds are switched from rx to tx. I even disassembled an NMN6191C telemike unit but that is far to complex to understand (at least for me....)Can someone help me with this and explain to me how these handhelds are switched via the accessoryconnector or mayby someone has allready build a repeater with it....... Your help is much appreciated! 73' Wim, PE1PME
