Wireless Data Communication system
This project is used to communicate or transmit a text message from one place to another place through wireless. The text message is encrypted by using the Microcontroller and the encrypted message was transmitted through wireless. At the receiver end...
6 meter vertical antenna
Easy to build homemade 50 MHz (6-meter band) vertical half-wave antenna. Omnidirectional, high gain, low SWR.
The proposed design for a 50 MHz vertical half-wave antenna is intended for amateur radio applications, specifically within the 6-meter band. This antenna configuration is...
Antenna Circuits / Schematics
This document presents plans for a simple ground plane antenna that is effective in the FM band (88-108 MHz). It is constructed from a small plastic disk. The 6 x 6 loop antenna, designed by Graham Maynard, is highlighted as...
Remote antenna for 60 kHz (WWVB) reception
Inside the outdoor box where the loop is mounted, the amplifier circuitry is displayed. The four capacitors located at the lower-left corner of the perfboard are used to broadly resonate the receive loop. In the office building, which is a...
915-MHz antenna monopole
The Tab antenna is a folded monopole that you miniaturize by forming it into an inverted L with a downward bend at the end. You can solder it perpendicular to a pc board or build it as part of a...
LM1889 IC For Simple TV Transmitter
The following circuit illustrates a simple TV transmitter circuit diagram. This circuit is based on the LM1889 integrated circuit (IC). Features include quadrature chroma modulators and RF capabilities.
The circuit utilizes the LM1889 IC, which is designed for television applications, particularly...
Ground pole & 2-Half-Wave Dipole Antenna
This Antenna is most widely used all over the world. For example, when you see a police car it has a transmitter with Ground Pole Antenna. The body of the car serves as ground. It accepts load from a 50-ohm...
Simple TV Transmitter Circuit
This is a small TV transmitter circuit that transmits in VHF, utilizing negative sound modulation and PAL video modulation. It is suitable for countries that use the B and G system. T1 refers to a type of transformer. The value...
TRF Radios
A small Medium Wave antenna from a walkman with digital radio and a variable capacitor (VC) with two sections connected in parallel from an old Russian radio (2x280pF). It has been noted that in areas with strong signals, optimal performance...
