Re: [IRCA] KBXD 1480 Dallas, TX heard in Japan.
Thanks for posting this Paul. 1300UT on 26 November at this location, conditions were pretty poor for Asiatic signals, but then I wasn't listening from Dallas. On the other hand, a signal from Dallas to Japan passes pretty much overhead at my location. I wonder what antenna was being used? Yokusaka is coastal, but it's also seems to be part of greater Tokyo... best wishes, Nick At 16:39 01-12-13, you wrote: Date: 26 Nov 2013 Time: 1259UTC Location: Japan Yokosuka-city http://youtu.be/Qsh2lrpCqxo ___ 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] Short antenna radials
Yes indeed. They are 179.4 degrees. Scott Fybush once wrote that it is a Franklin. We got a tour of the KSTP day site during the joint convention and I think he called it a Franklin then. Perhaps there is a difference of opinion. A unique and extremely efficient antenna no matter want you call it.

Re: [IRCA] Short antenna radials
180 degree (or vicinity) towers are uncommon; especially on the low end of the band. Many are used by 50 KW stations. The KSTP night signal is directional with a sharp null to the east southeast to protect WFED in Washington DC. For some reason the three night towers are different heights; 216.5 degrees (184 degrees and 32.5 degrees of top loading), 184 degrees and 160 degrees. I don't know why. For reference 180 degrees is one half wavelength and 90 degrees (very common) is one quarter wavelength. Here's an interesting chart. http://www.eriinc.com/Files/fc/fcec575c-5a91-455b-bcfa-5b8bf0d5ff1b.pdf Here's a wavelength converter to change degrees to height or vice versa. All AM tower heights on the FCC website are in electrical degrees. http://www.jampro.com/uploads/tech_calc/wavelength.htm Date: Sun, 1 Dec 2013 13:02:30 -0600 From: Forrest Skaine todftscytj7...@gmail.com To: IRCA Mailing list for the International Radio Club of America irca@hard-core-dx.com Subject: Re: [IRCA] Short antenna radials Did you mean that KSTP night facilities?

Is your antenna located near the ocean, Okamura-san? That was a good signal from KBXD. I DX'ed from Erimo Misaki in Hokkaido at the end of April 2007, with a Wellbrook ALA100 loop antenna.
