COLT45 is a small multi-purpose device intended for the Amateur Radio operator, short wave listener, or other experimenters. Functions include a versatile frequency marker generator, a Morse code keyer, and a Morse code beacon generator with room for more functionality.
If you have ever attempted to do any projects that involved UHF/VHF frequencies, what is immediately apparent is that your normal test equipment is very inadequate. Standard TV signal space, for example, runs from 50 to 878 MHz. The cost of acquiring test equipment that operate at those frequencies, like signal generators or an [...]
How to build Antenna Analyser for ham-radio? this project will show you how to build it. The IW3HEV antenna analyser is a relatively simple antenna analyser designed by pa3ckr. The main part of the project is Microcontroller AVR Atmel ATMega32. It has a 1-60MHz DDS signal generator and uses a homebrew directional coupler plus [...]
