From New England SKYWARN Net Facebook page, WS1SM Ham Radio Blog:
For 22 years, SKYWARN™ Recognition Day, developed jointly by the National Weather Service and the American Radio Relay League, celebrates the contributions that volunteer SKYWARN™ radio operators make to the National Weather Service.
Similar to last year, because of COVID-19 restrictions, ham operators will not have access to the NWS Gray facility, but we encourage you to take turns activating the WX1GYX call sign, either from your home stations, portable, or mobile, during the event.
If you’d like to use the WX1GYX call sign during SRD, please click here to sign up for a time/band slot. We hope to have at least one operator from each of the counties in the NWS Gray, Maine Weather Forecast area, so spread the word!
Participants are asked to log contacts in an electronic logging program, such as N1MM, and submit to firstname.lastname@example.org in an ADIF format.
During the periods that you’re not using the WX1GYX call sign, operators may also use their personal call signs to exchange their name, SRD number (which can be obtained here) and current weather conditions with other participating stations.
The event website provides complete operating guidelines, including the suggested exchange. SRD is a fun on-air activity that feels very much like a contest, but its informal. There’s no rules or band limitations. You can even use repeaters!
