The LMT1 transmitter and LMR1 receiver modules offer a 12.5kHz / 25kHz channel spacing 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.
