AM Murania Radio Receiver Question


Philip Karras <ke3fl@...>
 

From pg 5 of the muraniamanual.pdf:

Power and Voltage Regulator
The Murania circuit uses a red LED as a voltage regulator for the receiver. The LED also serves as both a power-on lamp and a tuning indicator. This circuit will be installed and checked for proper operation before continuing.

Can someone explain what voltage is this LED regulating? For what purpose?

Tnx es 73 de KE3FL,
