The TR1M narrow band multi channel transceiver
module is intended as a general purpose VHF data communication
unit. It is available on any frequency between 135 and 175MHz
(in 3MHz bands) and delivers up to 100mW RF output. This transceiver
offers a low power, reliable data link in an industry standard
footprint. For added flexibility it shares a common pinout
with the UHF TR1M module.
