FM radio transceiver module Radiometrix
169 MHZ Dual VCO, 1-500 mW

The Radiometrix UHX1 is a high-specification telemetry radio tranceiver.

The Narrow Band FM multi-channel VHF transceiver unit ideal for use in the new 169.4-169.475MHz European band. Squeezed into a compact, low profile package (67x30x12mm), it can provide a reliable data link capable of supporting rates of up to 5kbit/s or 1200 baud modem link over a range of more than 1km.

The dual frequency capability allows UHX1's transmitter section to be operated on one frequency while receiver frequency on another.
