Iowa Amateur Networks Frequency's

NWS offices around the country utilize various spotter networks for severe and other inclement weather verification and reporting. The various spotter networks are comprised of emergency management officials, law enforcement, fire fighters, EMS personnel, and road crews. We also utilize the general public with training taking place during the late winter and early spring as NWS personnel travel to various counties to provide training. A final group of spotters utilized by our NWS office are amateur radio operators.

For now, we will not list 2 meter and 70 cm repeaters outside of our 51 county warning area (depicted by the purple outline), unless they also serve some of our counties. If you notice errors or omissions, know of new repeaters that need to be added, need to change your spotter address or phone number, or just have a SKYWARN/spotting question, drop us a line at dmx.spotteradmin@noaa.gov and we take care of your request ASAP. Note: This email address is not for sending severe weather reports, but instead is for administrative tasks.

Keep in mind the maps depict approximate signal coverage with radio propagation characteristics, geography, equipment reliability, etc. all affecting coverage of a given repeater. Since many of these repeaters are linked please give them a second or two to connect.

Here's a three page pdf file of the same information in a format that will print nicely on three pages.
