BFDX MT-7250 DMR Mobile

BFDXDoor Hans PD0AC, Ham Radio Blog PD0AC
We knew BFDX already as a manufacturer of affordable DMR hand helds, and now a 30 Watt mobile radio popped up on the screen: the BFDX MT-7250. Grapevine Ham Radio sells this model for $329.99.

I find the number of channels/zones (160/50) a bit disappointing, but the price is right.
