RX1
VHF Narrow Band FM Receiver
The TX1 and RX1 form a miniature VHF radio transmitter/receiver pair designed for PCB mounting and suitable for extended range data links at speeds up to 10kbps. Link ranges of 10km+ are achievable with suitable choice of data rate and antennas.
vailable for licence-exempt operation in the UK 173MHz bands, the TX1 & RX1 modules combine effective screening with internal filtering to minimise spurious radiation and susceptibility thereby ensuring EMC compliance.
