4 Valve Broadcast Band Transmitter.
An interesting article for Wireless Weekly readers who have obtained their Amateur License to build a simple broadcast band transmitter capable of CW or Telephony with the throw of a switch.
With the switch in the telephony position two valves are used as modulators and two as oscillators.
In the CW position the four valves are used as an oscillator and the key breaks the oscillations by breaking the grid leak circuit.Wireless Weekly arranged for Arthur Watt to listen for readers testing their transmitters on his Amateur Station 2WW.
