Long range TETRA DMO-R links. Issues, tips and tricks.

Dear Gabor,

Could you please tell me how are you using Motorola MTH/MTP with 1B mode repeater? There are no such setting in Motorola terminals (at least I can't find it in a regular CPS).

Or information about repeater is transmitted over the air, including duplex shift? And Motorola radio does everything automatically? This is just my assumption.

I have 8 MTH-800 (FW 8661) and 2 MTP-850S (FW MR14 and FW 8465) radios.
Sipmle: the terminals getting all the information about repeater mode (1A or 1B, shift direction, duplex difference) through the repeater control signal.
No special setting is needed in the CPS Plus.
(Sepura, EADS-Cassidian and all other rerminals do that too).

All information about the DMO and DMO-repeater mode here:

Great to know. Thanks a lot for the info.

There is one important column (in the DMO chanel settings)
Communication type:
Direct: only MS-MS
Repeater: if there is any repeater: automatic connection, if not: MS-MS (no repeater found: you got blinking green triangle in the right upper corner on your terminals display, connected to repeater: constant green triangle). - i'm using this setting.
Repeater + Gateway if there is any repeater or gateway: automatic connection, if not: MS-MS

Yes, this is very known setting.
