07/14/2009 On August 17, W1AW, the Hiram Percy Maxim Memorial Station, will replace its AMTOR and ASCII transmissions with PSK31 and MFSK16, respectively. RTTY (Baudot) will continue to be the first digital mode used in the transmission schedule. The frequencies used by W1AW for all its digital transmissions will remain the same. “All regular 6 PM and 9 PM (ET) digital transmissions will begin with RTTY,” said W1AW Station Manager Joe Carcia, NJ1Q. “PSK31 and MFSK16 will be sent as time allows. The Tuesday and Friday Keplerian data bulletins will be sent using RTTY and PSK31.” The W1AW operating schedule -- complete with times and frequencies -- can be found on the ARRL Web site.
