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
