R-123 VHF TRANSCEIVER

R-123M transceiver provides for voice signal FM communication between mobile objects, equipped with frequency-compatible transceivers of the same type. It functions by means of a 4-meter rod aerial.The transceiver can be initially tuned-up to 4 fixed frequences. It allows establishing of communication without searching all four frequencies correspondent and communicates without additional frequency tuning.
