LMR1

VHF Narrow Band FM Low Cost Multi-Channel Radio Receiver

Frequency:173.200 - 173.325MHz (UK band); 150.825 - 152.450MHz (Australian Band), FCC Part 90 (custom)

The LMT1 transmitter and LMR1 receiver modules offer a multi channel, low power, and reliable VHF data link. This makes the LMT1/LMR1 pair ideally suited to those low power applications where existing wideband modules have insufficient range, or where low cost multi-channel operation is needed without compromising on RF specification or regulatory requirement.
