ARLB004 W1AW to change digital mode in Keplerian Data Transmission on Tuesday, March 31, 2026
Beginning with the 6:30 PM EDT (2230z) Keplerian data transmission on Tuesday, March 31, 2026, Hiram Percy Maxim Memorial Station W1AW will replace the second digital mode – BPSK31 – with MFSK16.
RTTY (Baudot) will continue to be the first digital mode used in the Keplerian data transmissions. The frequencies used by W1AW for all its digital transmissions remain the same.
The current W1AW operating schedule – complete with times and frequencies – can be found on the ARRL website at www.arrl.org/w1aw-operating-schedule. The online digital schedule will be updated on the day of the Keplerian data transmission mode change.
