Transmitter output power around 1W. Standard antennas - 2.5 m vertical or 6.4 meter long flexible wire. Field telephone type handset to listen and talk. Wooden carry case with belts for transceiver and batteries, full weight - 21 kg. Two meters on the front panel have been characteristic of A-7 only.
