Dual True Diversity UHF miniature camera receiver. The MCR41S-42S combines two internally coupled RX boards in a true diversity configuration, enabling broadband operation up to 240 MHz in the UHF band. A low-power DSP-based hybrid processor provides analogue and digital outputs with robust PTT telemetry. It supports 40 groups of 60 programmable frequencies, IR programming and transmitter sync, and can be used as a standalone unit or slot-in module; an optional second RX board upgrades an MCR41 to MCR42.
