Windows application that will allow you to perform calculations with the popular Maidenhead Grid Square system. This grid system is used worldwide by amateur radio operators for many aspects of ham radio.

The _59+ Log_ software, part of the 59+ collection, functions as a logging tool for Windows operating systems, specifically tested on Windows XP where its logbook feature operates smoothly. This collection also includes _59+ CW_, a module designed for Morse code operations, enabling keying of the COM port for transceiver control or simply listening to CW signals via the speaker. The software package, originally hosted on idealog.net, is now available for download as 59soft14.zip (3.4 MB) from IW5EDI's site. While the logbook application is functional, the _59+ CW_ application may encounter issues on newer Windows versions, as indicated by a failure to start on Windows XP during testing. The analyzer and convert modules within the 59+ suite require registration and do not operate in trial mode. Development and support for this software have been discontinued.

KSM Kenwood Smart Memory is a program to read and update the memory channels of a Kenwood amateur radio. The current supported types are: TS-450S, TS-570D, TS-570S, TS-690S, TS-870S, TS-940S,TS-950S.
