Database to record your shack equipment

Shack Equipment Database

A basic database to keep record of radios and equipment in your shack. Included are a variety of examples to see what can be added.

Instructions for download:
Some browsers don't allow you to download database files as macros are seen as potential virus threats. Thus the .mdb extension has been altered to .md . Once you have downloaded the file, change the extension to .mdb and the program will work in MS Access.
