Below is a list of communications based frequency calculators, information tables, conversion charts and converter programs available for use. Some of these are directly related to interest in communications and some are of indirect interest. We have written these or provided these for educational purposes and convenience. Some are written as demonstrations of programming techniques and others have highly functional uses. We are always receptive to comments or suggestions you may have. I would like to acknowledge Ed Womble of North Florida Communications in Jacksonville Florida as the person that instilled a love of radio technology. He was the foundation for most of the knowledge that I have provided in these frequency pages. Enjoy!
