From Dave G3YMC

My 1987 Klingenfuss Guide to Facsimile Stations lists DCF39 on 139.0kHz as
a FAX station.  Presumably now that it is transmitting other data the last
letter has been changed from F (for Fax) to B, to indicate this.

I note with interest the repeated comments about good receivers.  We should
keep encouraging stations to improve their receive set ups, as some
stations are certainly lacking in this area.  Keep up the good work Mike -
many of my QSOs are very much dependent on the other chap's receiver!
