Since there are getting to be so many new hams on here, I thought I would repost this info. It's a good list to get started with if you are in the DFW Metromess. Also, if you are up in the DFW area, we can always use more storm spotters. Check at this link toward the end of the year for the updated spotter schedule for North Texas. http://www.weather.gov/fwd/skywarnsch?sptrsch
There is also info at http://www.wx5fwd.org
. This is the site for the radio operators that work at the National Weather Service office in Fort Worth during severe weather events.
If you radio isn't programmed, probably the best frequencies/repeaters to program initially is the area Skywarn frequencies that are used for severe weather reporting. They are the main frequencies for the particular county/city so they are always being used.
There is also a wide area network of repeaters, http://www.nctc.info
. This group covers west to Abilene/Eastland and east to Sulphur Springs. It also can be linked to another group and covers portion of Arkansas and Louisiana. These are on a different frequency band, but I believe your radio is a dual band so these should work. They have several frequencies but since they are all linked together, you don't need all programmed. Here are 2 closest to you. Arlington is likely your best bet. It's a very wide coverage repeater.
