49MHz Toy RF Transmitter
This circuit is sourced from a remote control tarantula transmitter that operates at a frequency of 49.86 MHz. The schematic is also available on the FCC website by searching for the FCC ID. This device complies with Part 15.235 of...
255W Valve RF Transmitter circuit
This 255W transmitter operates using coils designed for both medium and short waves. The antenna power is set at 255W and includes four operational states. The first state utilizes an EF80 tube functioning as a Colpitts Clapp oscillator. Frequency selection...
Deviation Meter
A deviation monitor can be constructed by connecting a frequency modulation (FM) detector to an AC voltmeter, calibrating the meter in units of frequency deviation. One method for detecting or demodulating the FM signal is via a phase-locked loop (PLL)....
