Simple UHF Video Transmitter
This video transmitter circuit operates on the UHF channel frequency of 470-580 MHz, specifically channels 21-34. It can transmit video signals over distances ranging from 30 to 100 meters when using a cable length of 10 to 20 cm. For...
Visual modulation indicator
The brightness of the indicator lamp changes in accordance with the modulated RF signal. Adjust resistor R2 while the transmitter is on (modulated) until the lamp flashes in sync with the modulation.
Cl = 5 pF, C2 = 100 pF, Dl...
Simple Direct Conversion Receiver
A low-cost continuous wave (CW) superheterodyne receiver operates with a 4.00 MHz intermediate frequency. While there is no automatic gain control (AGC) or RF gain control, the receiver demonstrates good large signal handling capabilities. The design incorporates six bipolar transistors...
Original 2N2/40 Schematic Diagrams
This section describes the components of the receiver, which includes the post-mixer amplifier, variable crystal filter, intermediate frequency (IF) amplifier, product detector, local oscillator, receiver muting, and audio amplifier. The transmit section features the local oscillator, transmit single balanced mixer,...
RF OSCILLATOR CIRCUITS
A widely recognized circuit is the Hartley oscillator, which is characterized by a tapped coil within the LC tank circuit. The tap point of the coil is grounded. The oscillator's amplifier section functions as a common-emitter amplifier, resulting in the...

As a follow-up to the previous post, it was discovered that the Sony SRF-59, although inexpensive, offers surprisingly good performance due to its creative receiver architecture. Research was conducted on external antennas to improve reception of weak stations. Among the...
The PLL synthesized oscillator circuit diagram
The PLL synthesizer oscillator circuit is a feedback loop consisting of a reference oscillator, phase comparator, loop filter, voltage-controlled oscillator, programmable frequency divider, and various other components. In this circuit, the reference oscillator employs a crystal oscillator (OSC) to output...
Wireless Communication Hobby Projects
Another method of testing the received signal strength on a Symphony-based wireless network is with a homebrew signal meter. The National LMX2240 Intermediate Frequency Receiver has a pin called "RSSI Out." RSSI stands for Relative Signal Strength Indicator and provides...
PLL Oscillator for Medium Wave Frequency
A PLL oscillator, or phase-locked loop oscillator, is a control method that compares a controlled system or plant to a reference signal.
A phase-locked loop (PLL) oscillator is a sophisticated electronic circuit designed to synchronize an output signal's phase and frequency...
