HF Narrow Band Transmitter



The 10kHz channel NBFM NTX0-27.095 5-10mW transmitter and NRX0 receiver operate on the license exempt 27MHz SRD HF allocation. These modules offer a low power, reliable data link in a Radiometrix SIL standard pin out and foot print. This makes the NTX0/NRX0 pair ideally suited to those low power applications where existing single frequency wideband UHF modules have insufficient range, and in parts of the world where other frequency bands are not appropriate
