On 1520, doesn't KOKC also have to fight 1530 KFBK Sacramento's IBOC? Or do they not blast as much of a signal toward you as they do toward me? KFBK is a monster signal here at night, and only a few skywave signals are equal or stronger. One of those is the Disney outlet near Phoenix, 1580 KMIK Tempe, AZ. They have a HUGE lobe toward me, and have on occasion actually been as strong as (if not stronger than) my local 5kW on 600 at 8 miles, 50kW (night) on 690 at 32 miles, 5kW (day pattern) on 910 at 9 miles, 2.9kW (night) on 1170 same site as 910 and 1kW on 1360 at 8 miles. Using the Select-A-Tenna and a utility pole ground wire, I've actually been able to get them to display 91 dBuV relative signal strength on my Tecsun PL-606 (not sure if you're familiar with that model or other SiLabs Si4734-based DSP radios), a level for which I likely need to be within 1/4 mile or closer to the transmitter site to get that with the built-in ferrite bar antenna. Even the 2nd harmonic can be read here with that antenna setup. I'm even suspecting the 91 dBuV isn't the highest it would achieve here - a local on 1470, whose signal 1580 has often eclipsed, is displaying 96 dBuV with the SAT+groundwire, and was starting to overload. (98dBuV is the max the radio will normally display, although I've gotten it to display 99 a few fleeting times, by sweeping a signal generator across it and catching it right on a DSP chip sensor refresh. With extremely strong signals (usually upper 80s dBu and stronger), when first tuning to a signal it will show a very high reading then snap down to a lower reading which it holds, as in this example.)

But KOKC -OK City has a monster lobe in my direction and has always been dominant here at night. I get KFAQ-Tulsa, the old KVOO too, but KOKC is stronger. KFAQ has to fight the KSL IBOC besides. 73, Patrick Patrick Martin Seaside OR KGED QSL Manager _______________________________________________ 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] _______________________________________________ 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]
