This page is devoted to the state of Maryland. It contains links for Trunktracker information and conventional data, along with amateur radio sites.

Digital trunktrackers made by GRE, Radio Shack and Uniden can trunk digital systems, such as the city of Baltimore and Montgomery County. However, along with the ability to digitally trunk, these scanners are more complex than their predecessors. Many people find it easier to download data from a known web site, and use an application to do the programming, rather than do it by hand. The popular RadioReference website has a subscription plan that allows a user to download data from their database, utilizing one of the many applications designed for this purpose. Links for these applications can be found here

If anyone should find other Maryland scanner related sites, please email ka3jjz at netscape dot com and we'll add the link, space permitting.
