Copies of bulletins transmitted by W1AW can be downloaded from http://www.arrl.org/w1aw ("Hiram Percy Maxim Memorial Station"). Non-bulletin digital data Keplerian elements for many amateur radio satellites are transmitted utilizing the common digital bulletin frequencies on Tuesdays and Fridays at 6:30 PM ET. A DX bulletin "replaces or is added to the regular bulletins" every week between 8 PM ET Thursday and 8 PM ET Friday. Guest operators Amateur radio operators who visit the Hiram Percy Maxim Memorial Station may operate the equipment and temporarily use the W1AW callsign. The current schedule allows for "guest operators" from 10 AM ET to 12 PM ET and 1 PM ET to 3:45 PM ET Monday through Friday excluding holidays. An original or photocopy of a valid Federal Communications Commission (FCC) issued amateur license is required to operate the station. W1AW offers a QSL card for those who have contacted the station over the air. The "retro"-looking card can be obtained by any licensed amateur—not just ARRL members—who send W1AW their own QSL card with an envelope along with sufficient return postage. QSL requests should be addressed to: 225 Main Street, Newington, CT 06111. Qualifying runs Qualifying Runs are transmitted on the same frequencies as the CW (morse code) transmissions. At the beginning of each code practice session, the schedule for the next qualifying run is presented. By successfully deciphering one minute of the message and submitting to W1AW a certification that the copy was made by the requester without aid a Certificate of Code Proficiency will be issued to the individual. Submissions, which must include the $10 fee, should be mailed to W1AW Qualifying Run, 225 Main Street, Newington, CT USA 06111. An amateur radio license is not required in order to receive this certificate. Broadcast frequencies Note that due to changes in ionospheric propagation caused by changing maximum usable frequency and frequency of optimum transmission it may not be possible to receive W1AW clearly on all frequencies. Note that the voice broadcasts are sent in the common mode for each frequency. Broadcast schedule Special Notes: A DX bulletin either replaces or is appended to the regular bulletins between 8 PM NAEST Thursday and 8 PM NAEST Friday. W1AW uses local North American Eastern Standard Time and observes daylight saving time in the summer. Listeners outside of the United States may therefore see the times change due to daylight saving time. Every Monday
