VX2M NBFM Vibration Resistant Category 1 Multi-channel Transceiver

VX2M is a 400MHz band transceiver conforming to the Radiometrix TR2M pinout. It uses a sophisticated combination of techniques to produce a very robust device with excellent resistance to vibration. It meets the ETSI Category 1 high performance receiver specification to be used where the operation of a SRD may have inherent safety of human life implications. It retains all the pin-functions of the parent TR2M (including noise operated squelch/carrier detect and separate digital/analogue inputs and outputs). It also supports the same internal i1200 modem as the TR2M.
