When conditions allow me to hear that one it's alone, and has a clean signal. At other times I see (and hear) the same mess you describe. Thanks for the congrats on Oct 21 logs. Yes, quite an unusual morning. I'd only heard 1521 and 1107 from Urumqi once before this season, but this month I've heard 1107 three times, and 1521 more than that. Certainly this has been an October to remember. 73, Nigel John Bryant Orcas Island, WA, USA Winradio G313e and various Ultralights Wellbrook Phased Array + Superloops ___ IRCA mailing list IRCA@hard-core-dx.com 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: irca@hard-core-dx.com ___ IRCA mailing list IRCA@hard-core-dx.com 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: irca@hard-core-dx.com

Re: [IRCA] 1107 from Asia
John, The 1107 kHz ragged-carrier mystery was noticed here last year also, and the threshold-level TP audio was almost always weak music, never with ID clues. Even after a Grayland trip last November, the 1107 mystery was unresolved. After setting up the 9' loop this month I made a serious effort to investigate who this weak 1107 music station was, and thanks to a tip from Chuck, I was able to check the KBS parallel during a music peak, to confirm the HLAV identity. Shortly thereafter, I could detect Korean-language speech on the frequency. According to Chuck, the station is never very strong, even at Grayland. Oddly, whenever HLAV has fair audio on 1107, the carrier sounds relatively clean. It seems that the ragged tone is coming from some other source, although I've never heard any co-channel TP with HLAV here (like the Japanese commercial stations you have heard). 73, Gary In a message dated 10/23/2009 11:44:31 A.M.
