ARRL Digital Bulletins

ARRL logo

The American Radio Relay League transmits digital bulletins for Amateur Radio Operators on a daily basis.  Frequencies are 3.5975, 7.095, 14.095, 18.1025, 21.095, 28.095 kHz and 147.555 MHz.  Bulletins are sent at 45.45-baud Baudot, PSK31 in BPSK mode and MFSK16 in a daily, revolving schedule.  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 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.

Shortwave Radiogram transmits digital text and images on an analog shortwave broadcast transmitter. The program is produced and presented by Dr. Kim Andrew Elliott KD9XB. Shortwave Radiogram continues VOA Radiogram's tradition testing new modes and is an interesting source for Digital Ops wishing to practice more with FLDIGI & FLAMP.
