WINS-1010, Globo-1220, CKCW and things like Astrakhan would occasionally appear as "splits". EBU had six monitoring stations. Of them, Tatsfield and Jurbise were the most prolific in reporting the lower power Eu signals, and the exact carrier offset they measured. The FBIS lists could be purchased by anyone through the Government Printing Office. I don't think anyone ever found out exactly who the "mole" was that provided the EBU lists (as copies) to GPN, the sole North American "consumer" of that data AFAIK. Gordon always delighted in showing off his latest copies, which appeared monthly, when we still had Boston-based DX parties in the late 60's. Despite the public GPO sales outlet, it always happened that, about every 18 months (when a new edition appeared), a complete set of FBIS lists - by freq, by location, and TV/VHF - would mysteriously appear in the mailbox of the current IDXD editor, mailed from PO Box 2604, Washington DC. in a plain manila envelope. Some of the FBIS entries were "listed operations" and had only fair to good data accuracy and the freqs were shown just to the nearest kHz. Just one of several data sources. You could tell by the print typeface that they were done on a big mainframe and a lineprinter, and offset mastered. DXing is so much less interesting these days. - Bob _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
