A 30 Mtr Direct Conversion Receiver for QRSS
The schematic for the crystal bandpass filter/amplifier board is illustrated, along with images of the assembled and boxed unit. The signal frequency bandpass filter is constructed over a ground plane and enclosed in a separate housing measuring 75 x 75...
Z3816A Modification
The Z3816A is a GPS disciplined timing source manufactured by HP in the mid-1990s, intended for use in cellular telephone equipment. It provides ten output signals through SMA connectors on the back panel. The first four connectors on the left...
Conversion Receiver For 160 To 20M Circuit
Note that T1 and T2 are TOKO components, including part numbers for the coils T1 and T2. The direct-conversion receiver shown utilizes a double-tuned input network made from readily available TOKO coils. IC1, an NE602, serves as a voltage-controlled oscillator...
REGENERATIVE_SHORTWAVE_RECEIVER
The receiver consists of multiple subassemblies, including an active antenna, an amplifier featuring regeneration control and band-switching circuitry, an AM detector, a power amplifier, and an output device such as an internal speaker, external speaker, or headphones. Additionally, it is...
The ATL-3 Loop Antenna
All ATL-3 loop windings are centre tapped and balanced w.r.t. their amplifier/receiver chassis ground, and therefore electric field interference pick up tends to self cancel. Magnetic noise fields, e.g. televisions and the electric meter box, or electromagnetically radiated interferences, may...
Ambient Power Module
The Ambient Power Module (APM) is a straightforward electronic circuit that, when connected to an antenna and an earth ground, can deliver a low voltage output of up to several milliwatts. An optimal setup involves a long wire antenna approximately...
MRFICl505R2 based GPS receiver RF front-end circuit
MRFICl505R2 is a 1.575GHz GPS downconverter chip. It integrates a mixer, VCO, PLL, crystal oscillator, A/D converter, loop filter, and other circuits. The MRFICl505R2 IF output frequency is 4.1MHz, with a typical conversion gain of 105dB, an operating voltage of...
gps driven clock compasss peedo
This project is a GPS-based clock that displays the current date, automatically adjusts for daylight saving time, shows current speed, maximum speed, and present heading in degrees relative to true north. The original firmware and concept were developed by Ken,...
Live Wire Antenna
Using live or neutral wire in AC household wiring as a receiving antenna is feasible only with a high-voltage capacitor inserted between the receiver antenna terminal and the live or neutral wire. This AC wiring antenna solution is often considered...
