Re: [IRCA] Identifying a Station by Parallel Programming
Hi, John. Reporting in from San Diego tonight. Your examples are excellent. Personally, I have no problem with "presumed" loggings. For example, if I hear a specific language on a TA station, I then look up the possibilities on the EMWG and deduce from it what the station "has to be". I may be 99.5 or 100% certain of the ID. Many stations never give any sort of ID, but based on the content one can easily deduce who they are. Another method one can argue is using the exact frequency now available using programs like Spectravue and SDRs like Perseus to give us a pretty exact frequency. Many stations are bang on some slightly off frequency, and these lists now exist (see MW offsets list). One can "see" the carrier and be quite certain of the station. A classic example of this is the Australian X-band station, Radio Brisvaani always on the high side of 1701 kHz. Yet another ID method is with the various CBC low power retransmitters. Overnight one hears their WRN programming. Based on which program is being heard, you can narrow it down to which time zone is being heard, and from there hopefully to one or more stations. Just a few ideas! .....Walt Salmaniw.
