I would suspect that if you have done even a bit of tuning around the HF dial in the last few months, you have probably heard W1AW/0-9 making contacts. This week W1AW, the ARRL mothership in Newington, CT, has been on the air as W100AW in celebration of the ARRL anniversary.

As busy as that sounds, W1AW is consistently on the air with a great variety of activities. Yesterday I took the opportunity to copy their digital modes broadcast.

ARRL has various means of promulgating a great deal of information. The primary way I usually receive a good portion of it is via email. I thought it would be interesting if I could try and copy their digital transmission of their bulletin, which I was able to do yesterday.

Every weekday, W1AW sends out a bulletin twice a day on multiple bands while rotating through three different digital modes: Baudot (RTTY), PSK31, MFSK16. The first broadcast kicked off at 5pm (local) which I was able to copy of 17M (18.105 MHz). It appears to be ARRL’s propagation bulletin. Here is what I copied:

Please find my full copy here.

Later in the evening (8pm local), I copied the next broadcast which looks like their DX bulletin:

…. and the complete text is here.

During the 8pm transmission, I was able to copy the bulletin on 10M, 15M, 17M, and 20M. I could not find it on 40M or 80M.

Although these bulletins are easily obtainable via email or from ARRL’s website, I enjoyed copying the broadcast from here in eastern Kansas.
