  1. Not one of your tasty pasty clipart mods eh Hans?

    Saying all that I feel this is the year of the mass produced DMR handheld, and if it comes at us at the right price the end could soon be nigh for Death Star!

    • Let’s see what the quality is like, Steve.

      What I’ve seen and touched so far in the low budget DMR section must still bow to the Connect Systems C700.

  2. It works fine, I tested with Motorola radios. Similar programming, soft
    is very good. Quality product.

  3. the antenna is GPS & radio 2 in 1 design, does it build in GPS function ? And does it can talk with other band DMR repeater just like the CS700 ?

    • For the first question you have to contact the manufacturer. Sometimes specs on paper seem to promise more than you really get. The radio will function on any DRM network.
