This is a manufacturer that got a foot in the door sometime back however they have been quiet for some time.
Recently, they have started promoting the CDR-300UV “mini” mobile dual band DMR / analogue radio. The unit is a little narrower than the Anytone AT-D578UV, around the same height and nearly 1/3 of the depth [121.5mm high, 65.5mm wide and 42.5mm depth] making not only ideal for mobile but also portable use. The unit includes a record function, 4000 channels, dual VFO, 10w/20w output and covers 134-174MHz / 400-480MHz.
