Frequency Programmable 25kHz NBFM VHF Transceiver
The narrow band NiM1B transceiver offers
a low power, reliable data link in a
Radiometrix transceiver standard pin out
and footprint. The NiM1B is a frequency
programmable,
narrowband
design,
suitable for licensed and unlicensed VHF
allocations, FCC part 90 and part 95
(MURS) operations.
Features

The NiM1B is a half duplex radio transceiver module for use in long range bi-directional data transfer
applications at ranges up to 1kilometres. The module operates on the US 154MHz MURS band allocation.
NiM1B is also available as separate NiM1BT transmitter and NiM1BR receiver, which can be, used as dual-
in-line equivalents of TX1 transmitter and RX1/NRX1 receiver respectively.
Applications
. Multi-Use Radio Service (MURS)
. Industrial telemetry and telecommand
. High-end security systems
. Vehicle data up/download
. ROV/machinery controls
