This is a home-brew Frequency Counter that I built and that looks Commertial. It was designed by two hams on their lunch hours - hence the name. The prototype drew a lot of interest and it became a Club project. Interest was so high that they decided to make production PC boards and sell a parts kit. I bought a kit and purchased the rest of the parts and put them in storage. Two years ago I found time to build it, and here it is. Here are some of the Specifications. DISPLAY - six digits, big enough to read. FREQUENCY RANGE - audio ( touchtone pads) through all the popular amateur bands (1.8 MHz to 450 MHz). SENSITIVITY - sufficient for most solid-state rigs, but not sensitive enough to produce unnecessary counting on noise (10 mV to25 mV). ACCURACY - +/- 10 Hz to +/- 100Hz. and POWER - 12 V dc. The article then goes on to explain the Design , Troubleshooting, Wiring and Parts List. Schematic is also included along with more pictures. I had no problems making this unit and it worked when completed.
