Product Description

The M604A is the ultimate VHF radio, with classic styling and features like a plug-and-play speaker mic and AquaQuake drainage system to remove water trapped in the speaker grille. You’ll get quicker channel selection from the speaker mic with its favorite channel feature, and easy-to-read GPS information on the generously sized dot-matrix display. A convenient receiver-repeater feature lets you monitor the radio through the hailer horn. The M604A is also full-feature DSC equipped (complies with new 2011 ITU Class D requirements), comes with a built-in 30 watt “true hailer.” In addition, it is fully controllable by the COMMANDMICIII™, or selectively controllable by the COMMANDMICII™.

    I have previously owned five different fixed-base VHF radios, all good and top of the line, but this one is the best for impressive range, good audio, dependability, and understandable features.
