Radio circuits built

This receiver is a modification of Charles Wenzel's Two Transistor Reflex Radio. Instead of a ferrite AM loopstick antenna, a magnetic loop antenna is used, and an LM386 amplifier stage has been added to drive an 8-ohm speaker. A switch...

Noisy Regen Receiver

The following circuit illustrates a Noisy Regenerative Receiver Circuit Diagram. Features include a Noisy Regenerative Receiver Circuit, which simplifies the process of... The Noisy Regenerative Receiver Circuit is designed to amplify weak radio frequency signals while also incorporating a regenerative feedback...

Simple GPS Disciplined Reference

This design was developed to create a highly stable reference locked to a 10MHz source. With minor hardware modifications and entirely new firmware, an excellent GPS Disciplined Oscillator (GPSDO) was achieved using the same circuit board. The design effectively locks...

gps voice interface for wouxun kg uv3d circuit

Connect the Byonics TinyTrak 3+ GPS modem, helmet earbud/mic, and external battery pack to the Z-1A, which is incompatible with the Wouxun. The KG-UV3D utilizes the Kenwood HT interface with a single ground for mic, speaker, and PTT functions, eliminating...

Receiver Audio Circuit

This simple receiver AF amplifier can supply several hundred milliwatts to an 8-ohm speaker. The gain is approximately 200X. If high gain is not required, C2 can be removed, resulting in a gain of 20. R1 and C6 are essential...

Instrumenting an Earth Satellite

In October 1958, when this article was written, only a year had passed since the successful launch of Sputnik, followed shortly by the launch of the Echo satellites, marking significant milestones for Russia and the USA, respectively. Prior to these...

GPS receiver

This GPS receiver is powered by 2 AA batteries. They are only strong enough for the GPS to stay on for about two hours, and this seems like quite a waste. I would like to be able to use a...

gps galileo dual rf front end receiver

This topic will detail the design of each block of the radio frequency (RF) front-end, taking into account the technical requirements outlined previously. The design aims to meet specific specifications. The RF front-end is a critical component in communication systems, serving...
