RF oscillator circuit (2N3904)
This basic RF oscillator circuit is easy to build and the components are not critical. Most of them can be found in your junk parts box. The L1 antenna coil can be made by close winding 8 to 10 turns...
Precision QRP Transmitter
This compact transmitter is suitable for less demanding Doppler propagation measurements. It is designed for operation on the 80m band but can be easily adapted for the 40m or 20m bands. The output power is approximately 500mW of unmodulated carrier,...
Bandswitched Grid Dip Meter
This circuit is designed for checking resonances in tuned circuits, antennas, and similar applications, covering a frequency range of 2 to 20 MHz. Q1 acts as an oscillator that can be tuned across this range using capacitor C1 and band-switched...
Sensitive RF Voltmeter Probe
Sensitive RF Voltmeter Probe Circuit. This circuit measures RF voltages beyond 200 MHz and up to about 5 V. PARTS LIST: R1 - 4.7 MΩ, R2 - 1 MΩ, R3 - 1 MΩ, R4 - 100 kΩ, R5 - 330...
Miniature MW Transmitter
Here is a very simple, inexpensive and interesting project which provides lot of fun to a home experimenter or hobbyist. This simple transmitter can transmit speeches or songs within a short range. The circuit uses only one transistor. The entire...
Remote tuning transmitter
This project consists of a wide range receiver and one transmitter. Together they will form a unit which will help you tuning your homebrewed transmitter. The most difficult part of homebrewing is the tuning part of the transmitters. How should...
Remote Control Mains Switch
As the only electronics engineer in the family and circle of friends, it is sometimes not possible to avoid requests for assistance. Recently, a request was made by an elderly lady residing in a retirement home. In her room, the...
