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.
