Superregenerative receiver
This is a simple RF receiver mainly for low-distance digital radio receiver application. The analog output of this circuit should be connected to a schmitt-trigger signal conditioning circuit with a proper value capacitor (from collector of T3). L1 for 27Mhz...
FM TUNE UP
At some point, every amateur radio operator working with FM radios needs to tune the transmitter and receiver. For those with access to professional test equipment, this task is straightforward. However, for those without such equipment, a more inventive approach...

SC1088 AUTO SEARCH TUNING FM RADIO RECEIVER
The SC1437 is a battery overvoltage detection circuit that includes a driver for an external MOSFET. The trip point can be adjusted using an external resistor divider connected to the SENSE pin. If no external divider is used, the trip...
TEA5764UK TEA5764UK FM Radio + RDS
The TK10931V is an intermediate frequency (IF) integrated circuit that incorporates two IF systems—one designated for frequency modulation (FM) and the other for amplitude modulation (AM)—along with a detector. This device is suitable for use in amateur radios, CB radios,...
One Transistor FM Radio With Improved Audio Gain
The following circuit presents a schematic diagram for a one-transistor FM radio with enhanced audio gain. Features include a super-regenerative design.
The one-transistor FM radio circuit utilizes a super-regenerative architecture, which is known for its simplicity and efficiency in receiving FM...
tda9887 if pll demodulator fm radio circuit
The integrated circuit (IC) is a multistandard vision and sound intermediate frequency (IF) phase-locked loop (PLL) demodulator that operates without the need for alignment. It supports multiple television standards, including PAL, SECAM, and NTSC, and is capable of handling both...
42 Mc Band to 88 Mc Band (retrofit converter) Project
Before World War II the FM radio band was just below 50 Mc. Read all about it. If you have such a radio, you might want to build this converter. It will let your old set receive the modern FM...
