Design for a very low cost 6-digit frequency counter module using of the shelf components -
Pictures, photos, source code and plans to build a logging frequency counter -
Modification to connect a frequency counter to a MFJ-9406 50 MHz transceiver by ON6MU -
Frequency counter project. It includes quite a number of useful testing features which were very useful when building other projects -
This is an incredibly simple and cheap frequency counter with binary readout, based on the ideas of Onno PA2OHH. -
The Burnham Beaches Radio Club frequency counter is a PIC micro controller based frequency counter with LCD readout. It can be used stand alone or the in built offsets allow integration into a receiver -
Improve the FRG-7 operation adding a home made digital frequency display. The author explains the challenges of using the analogue dial on the FRG-7 and how a digital display can be a useful solution. The page provides detailed information about the FRG-7's design and frequency conversion process. It also includes step-by-step instructions on how to connect an external frequency counter to display the kHz part of the frequency. -
This circuit will let you look at the signal and frequency output of your transceiver. -
PIC micro controller based frequency counter with LCD readout -
A tutorial on using RF frequency counter, how a digital frequency counter works, includes frequency counter specifications and best practices in setting counter accuracy and resolution -
This Frequency Counter Development Kit is fully functional with the included pre-programmed microprocessor -
homebrew a frequency counter by M1HOG -
This page by Andrew Woodfield ZL2PD provides information on CMOS HF Digital Dial for hams. It covers design options, circuit description, construction, alignment, and operation. The page also includes references and downloads. Whether you're looking to build or understand a digital dial for your HF rig, this page offers valuable insights and resources. -
This page provides an introduction to the ZL2PD LED Frequency Counter. It covers the design, construction notes, and downloads related to the project. Created by Andrew Woodfield, ZL2PD, this resource offers valuable information for hams interested in building their own frequency counter using LEDs. The content is dated June 12, 2010, with a revised version 2.0. The page also credits the template design by Andreas Viklund.
