MTH300

This is the oldest model of Tetra terminal that I own, but it is probably the most enjoyable.

It does all the things that come with TETRA standard terminals, such as group and private calling, text messaging etc. Mine is 1W output power and covers 410-430 MHz.

Non colour dot matrix screen (so no pictures) but CAN work in DMO mode as well as TMO. I never have managed to get this to work with a duplex DMO repeater (Cleartone CM9000).

There was another version of this radio designated d700 when in use on the Dolphin network, and although I haven't actually used one of the ex-Dolphin units, other Tetra terminals destined for this use were somewhat "custom" and refused to accept DMO talkgroups. 

The programming kit for the MTP300 is CRAZY expensive see here, so don't be offended when people refuse to "share" something that it took 6 months to save for!

The audio quality from these is exactly the same as from a brand new MTH800 (fantastic) and the battery life (with extended battery) is phenomenal (around 20 hours with light use)
