Re: [IRCA] New Station / SF 680 ,810
On a trip by plane to the Oshkosh Airshow in 2005 I did a scan on the SF stations in a small town stopover in eastern Montana and got KNBR with mixed results but no KGO which maybe verified my assumption that KGO is pushing mostly north- south as they claim ( mentioned on the air by Bill Wartenberg that they go all the way from Baja to Alaska ) and very little to the east and that would be logical since the biggest population of listeners is less than 200 miles from the coast.KNBR probably has a wider or more circular coverage area and is going more to the east at night. CBU Vancouver's TX site is located on mudflats as far west as land will allow south of the city near the international airport and has the strongest footprint here on Vancouver Island. As it is weaker to the hilly east and into the Fraser Valley it is coverage augmented by FM LPRTs in some towns east of Vancouver.

KNBR is Non Directional, having one tower. KGO is located by the Dumbarton Bridge, just North of San Jose and is directional N/S, but most of it is sent North. KGO has a great signal in Alaska at night too. 73, Patrick Patrick Martin Seaside OR KGED QSL Manager ___ 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

No probably about it - as a former class I-B clear channel station, KGO shares 810 with another former I-B, WGY Schenectady, and each station has to protect the other one's signal at night. That's usually done with directional nighttime antennas at both I-B signal (think Buffalo and Oklahoma City on 1520, or Sacramento and Cincinnati on 1530, or Chicago/Seattle on 1000), but the KGO/WGY situation was a little different. Both stations were owned by GE, which wanted WGY as its flagship. WGY is non-directional day and night, and KGO ran with just 7500 watts until the 1940s, when it moved to its present transmitter site and went directional with 50,000 watts day and night. Because of the directional notches between the big 50,000-watt clears on I-B channels, it's typical for other (also directional) signals to get dropped in co-channel in between the I-B signals. In the case of 810, there was enough room between WGY and KGO for a 50,000-watt (day, at least) signal to go on the air in Kansas City, originally KCMO and now WHB. Much more recently, the former 800 station in Brighton, Colorado (near Denver) has moved to 810 and gone fulltime. 680 is non-directional and always has been; it was (at least in practice if not on paper) a I-A clear channel that didn't have to protect anyone else on its channel; much later on, the FCC authorized other high-power 680 signals in San Antonio, St. Joseph MO, Raleigh and Boston, all of which have to be directional protect KNBR. It is *highly* unusual for a former class I station to be operating at variance from its licensed directional pattern. It would be very obvious if it were happening - the stations on 810 in Denver and Kansas City, for instance, would notice very quickly if KGO lost its null in their direction. (KGO did operate non-directionally, at reduced power, for some time after the 1989 earthquake damaged two of its three towers. I suspect it may have been logged in the east back then...anyone have loggings from the winter of 1989-90?) s ___ 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

And there is one special place in Livermore (20 miles from their xmtr) where you can null them out completely. Great place to DX from if you're looking for 800 and 820.

kevin redding wrote: They have a rock solid signal in Arizona They sure do. The KGO pattern (same pattern day and night) isn't quite straight-up north/south. It's actually tilted slightly NNW/SSE to line up the null right at WGY, and that means the northern lobe aims up the Pacific coast at Patrick, while the night lobe also shoots down the coast and gets inland pretty decently to the southeast. The south lobe has a little less juice in it than the north lobe, but not by much. You can see the pattern here: http://fccinfo.com/CMDProEngine.php?sCurrentService=AMtabSearchType=ApplsAppIDNumber=249372sHours=U It's not good at all in Sacramento, and lousy at night in Reno and Salt Lake (and in Denver, before the 810 there signed on.) s ___ 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

Infact KGO made #2 in the ratings in the early 70s in Portland! It blew everyone away. That was before KPDQ-800 went nights, but KGO has a lot of NW listeners.
