Since the early days of System Studies, we've tried to provide our telco friends throughout the United States with helpful information about cable pressurization. In January, 1981 we published our first Gazette newsletter and mailed it to the individuals on our extensive mailing list. Almost 30 years later—after 52 Gazettes, 10 AirTalk newsletters, numerous Flow Finder Product Updates and regional bulletins—we discovered an easier, more effective way to reach our readership: email.

In October of 2007 we sent off our first AirMAIL electronic bulletin. These periodic e-bulletins feature short topics of interest for our readers, including leak locating tips, product information and training updates. The table below contains links to PDF versions of the past bulletins. If you haven't received all of these issues and would like to catch up, you can view the printable PDF version here. Also, if you would like us to add you to our mailing list so you can begin to receive the new AirMAIL issues, give us a call or drop us some email. We'll make sure you get on the mailing list.
