Shortwave Log


Shortwave Log is a suite of applications for logging and radio control. Although it is called Shortwave Log (or SWLog), that is now primarily for historical reasons. SWLog started back in 1988 as an MS-DOS application just for shortwave. Today SWLog also is suited for any type of broadcast, beacon, or utility logging as well as for amateur radio logs. The particular twist for SWLog with regard to amateur radio logs is that it is data-centric. While other programs are tailored for specific tasks, SWLog focuses on the data and is intended to be the logbook of record. Other programs can be used to create the shortwave or amateur logs, while SWLog can then import the logs and have them stored in the database.

Logging for 33 years!

The functionality of the modern version of SWLog is just a tad greater than the original MS-DOS version from 1988! Here's is what the original program looked like in 1988. The software at the time was distributed on BBS systems. It was a shareware program where registration would be sent over the US Mail to a physical post office box. SWLog was the de facto name at the time because MS-DOS filenames were limited to the 8.3 format. For the classic computer aficionados, SWLog version 1 was coded under MS-DOS 3.30 on a Tandy 1000 SX with Turbo C and used Paradox as its database engine. SWLog still runs today under MS-DOS or even DosBox. Note the subtle Y2K bug and the old 80x25 text mode!
