Follow this link to a map of Texas which shows the North, West, and South Texas sections as definded by the ARRL. The STX part of the map has been setup so that if you click on a county the pop up table will display the Section, District and County Emergency Coordinators plus a link to where they can post meeting info. Then simply follow the County link.
Note: Not all browser and operating systems work 100%. For Windows 7 and 10 Firefox seems to work fine. If your browser shows just the Section, SEC, and County name you need to try a different browser.
