W1AW to alternate digital mode schedule

Beginning Monday, March 15, 2010, W1AW will alternate the digital modes used for its digital bulletin transmissions.

While Baudot, PSK31 and MFSK16 still make up the digital mode complement, the schedule will be altered to give more exposure to PSK31 and MFSK16.

Because of time constraints and the varying lengths of digital bulletins, there were many instances where only Baudot was used.

With the new schedule, amateurs preferring either PSK31 or MFSK16 will find these modes no longer secondary.

The regular callup will be made using the mode that is transmitted first. The digital bulletin times remain at 6 PM and 9 PM eastern, daily.

The Tuesday and Friday Keplerian data bulletins will continue to be sent using just Baudot and PSK31.

The new digital schedule is as follows:

Monday: Baudot, PSK31, MFSK16
Tuesday: PSK31, MFSK16, Baudot
Wednesday: MFSK16, Baudot, PSK31
Thursday: Baudot, PSK31, MFSK16
Friday: PSK31, Baudot, MFSK16

Given time constraints and bulletin lengths, all three modes may not always be transmitted.

The complete W1AW schedule can be found on page 100 of the January issue of QST, or on the web at,
