Murphy B-40 Communications Receiver
The B-40 is a general purpose HF communications receiver which were used in the late 50's by the Royal Navy and the Royal Australian Navy. Made in the United Kingdom by Murphy Radio Company. It had to be strong and reliable, sensitive and easy to use. It was literally built like a battleship, and had to stay on frequency, when the ship fired it's guns! Consequently weight was not a factor in it's design.
Has a continuous tuning range from 600 kHz to 30 Mhz, 500 kHz IF and a crystal filter. It is a single conversion super heterodyne receiver with two RF stages and three IF stages. It has a distinct looking front panel with a vertical frequency display, each band being illuminated in turn as frequency band is changed. It has a built in tiny speaker. It weighs 114 pounds!! and works on 115 or 240 Volts AC.
