  • Notes
  • The PM125 Hamble was a marine HF transmitter-receiver intended for voluntary installation in boats and yachts which were subject to the British Post Office Marine regulations.

    Single or double frequency simplex with direction-finding capabilities.

    The equipment had a transistorised, tunable receiver and an 8-channel crystal-controlled transmitter in separate cabinets.

    The RF power output was 20 Watts AM or CW into 50 Ohms.

    The internal power supply was also transistorised. A rotatable ferrite bar antenna for direction finding was mounted on the top of the cabinet.

    The frequencies covered were 150-400 KHz, 535-1605 KHz and 1.6-3.8 MHz. Reception of the Consol navigation system signals was possible with the equipment.

    12 Volt and 24 Volt DC-powered versions were available.
