Re: [IRCA] Nightsounds on 1570

[Stephen Airy <pianoplayer88key@xxxxxxxxx>]

When KMIK is strong, their IBOC totally covers 1570 and 1590.  They're pretty much on the opposite bearing to Hawaii, and my loop antenna has a figure 8 receive pattern.
I wonder if my best chance might be after Arizona sunrise and before California sunrise?  KMIK runs 50kW DA-N, with a huge lobe directed almost right at me, so at Tempe sunrise KMIK suddenly makes a noticeable drop in signal.  Also at that time of the morning, any trace of XERF would be negligible at best (and most likely non-existent).  After Riverside, CA sunrise, though, KPRO usually pops up and owns the frequency until it fades with D-layer re-ionization.
 
As for 1500, I often get the San Jose station from here, but it's usually very weak.  On some nights, I often get ESPN radio from KSTP St Paul, MN instead.  Otherwise, it's a relatively clean part of the dial - my nearest locals on the dial are 1470 XERCN and 1550 XEBG.  At night 1530 KFBK can put in a strong signal almost like KMIK, but not strong enough to intrude on 1500, and 1520 KOKC night / KVTA daytime aren't all that strong either.  Sometimes 1510 KSPA Ontario can put up a bit of a fight, but it usually has nowhere near the signal that KMIK and KFBK do, and I have nothing close enough on 1490 to dominate the frequency at night (although I do hear one or two stations in the daytime).
 
Oh... you don't think 10kW 760 KGU would have enough oomph to punch through a local 50kW co-channel (KFMB) from 7 miles away, do you? ;)  As for 670, KIRN Simi Valley usually dominates the frequency, and is audible throughout the day.  (Speaking of that frequency, I miss KBOI.)

Depending on if KUAU is using 15 KW. If the KMIK IBOC is strong, I am
sure that will make is rougher. 1500 Honolulu may be your best best as
they have been received in So CA many times through the years. They do
run 10 KW and I don't believe you have any IBOC on 1490 or 1510 to deal
with. 
  Here, my easiest Hawaiian these days is now KPUA-670. They are are
nightly visitor.
