PJ,

This is a noble goal, but there is a problem.

There are very very few over the air broadcasts of teletype signals.

Other list members will have much better information, but I know of only a few UN-encryped signals:

- there are occasional RTTY contests on the ham bands, but the operators are almost all using “glass teletypes”: that is, totally computerized systems with not a single metal machine on the premises.  The combination of the contest-content-only exchanges and failure to send CR and Linefeed make for frustrating copying for heavy metal machine users.

- a weather broadcast from some other country - Canada.  Here is info from 2005:

- an occasional broadcast from our astounding west coast maritime coast station KSM.  The chief operator and station URL are:

=================================
Richard Dillman, T2-GB-061170
Chief Operator, Coast Station KSM
Maritime Radio Historical Society

=================================

- ARRL broadcasts on W1AW.  Here is up to date information from:
http://www.arrl.org/w1aw-operating-schedule

Digital Transmissions

Frequencies are 3.5975, 7.095, 14.095, 18.1025, 21.095, 28.095 and 147.555 MHz.

Bulletins are sent using 45.45-baud Baudot, PSK31 in BPSK mode and MFSK16 on a daily revolving schedule.  
The actual daily schedule can be found here. <http://www.arrl.org/files/file/W1AW/W1AW%20Daily%20Digital%20Bulletin%20Schedule.pdf>

- I have a modest collection of graphic tapes, at least half of which is in the hands of Tom Tilson who is putting them out via some magic over the internet on saturdays.  Due to “family events”,  I have not been able to put together a station to broadcast them via real live radio waves.  I hope to do so eventually, though with a Valiant or S-line, Dovetron, and real Heavy metal machines.

If others on the list can add or correct this, please do.
