There are apparently 60 or so there in Helotes. Try using the callsign lookup at
www.arrl.org, and enter W5GMT, or even a dummy call sign. Either it will find it or not, but it will give you a chance to search for call signs in any city or zip code area. My quick search showed 68 entries for Helotes, but I'm sure some are duplicates, some have moved, and some are now inactive. GL
