This receiver features a real TRUE DIVERSITY configuration along with a unique wide-band tuning range of 230 MHz of bandwidth.

The software selectable

analogue and digital outputs

wideband and narrowband DSP-FM operation

gives users options based on their project needs.

The receiver also offers convenient function buttons, including a dedicated frequency scan option.
Battery management is flexible as it features standard battery packs that can be charged with the dedicated charger or through the micro-USB-B connector.
