The circuit may be used as a signal booster with VHF receivers whose front end suffers from low sensitivity (such as many valved and army surplus types).

This inexpensive FM radio receiver antenna booster uses the BF324 TO92 style pnp transistor in a grounded-base configuration.

The PCB is a single-sided type where the copper is on one side of the board. The ON/OFF switch and the audio jack can be found on the underneath belly of the PCB which are all supported by two machine screws elevated to a height that gives the two devices enough ground clearance. The 1K potentiometer is being used for the gain control. A total of 9 turns can be made without the use of VARIAC with 2 turn tap. It has a total of 7 turns with a 2 turn tap if it was intended for using a variable tuning capacitor. The LM386 audio amplifying circuitry is placed near the receiver.Ī homemade choke was created with a single layer tapped air core drain coil. The original design of the VHF receiver consists of 24 component counts which were trimmed down by taking away a single component until it reaches 12 component counts. The VHF super regenerative receiver has been trimmed down to a single transistor without compromising its tremendous sensitivity and selectivity while maintaining the same clear audio. The LM386 audio amplifying circuitry is placed near the receiver. In these days I began to use the transistor having ft over 1GHz. The VHF super regenerative receiver has been trimmed down to a single transistor without compromising its tremendous sensitivity and selectivity while maintaining the same clear audio. The original design of the VHF receiver consists of 24 component counts which were trimmed down by taking away a single component until it reaches 12 component counts. 5 transistor 144MHz FM receiver by JF1OZL In order to hear the 2m FM band, I made a simple radio.
