KTNN 660 loud and clear in Burbank tonight

[davideduardo]

When I originally thought KTNN might be able to be heard daytime in Southern California, I didn't realize how fer east in Arizona Window Rock actually is.

I assumed for some reason that it was not far from Phoenix until I actually looked at the map.

Even if it were in Phoenix, it would not likely have much of a signal beyond the border / Colorado River areas to the west. For example, LA's KFI barely makes it beyond Desert Center on the way to Arizona. By the time you get near Blythe, it's quite gone in the daytime.

This is sort of like wondering why you can't hear Orlando's 540 in Miami. It's just too far...

Remember, the distances in the west are often much greater than you might think.

If that's the case, David, then maybe you could explain how KFI could be heard midday in Cisco, UT (near Grand Junction, CO) and in Benson, AZ, to just past Willcox, AZ?

Also, slightly OT (or maybe not since the stations paths may cross this area) - Are there other places you know of, besides Coachella & Imperial Valleys / Salton Sea, where there's a land-locked area with excellent and terrible conductivities practically next to each other? (For example, maybe a 50kW omnidirectional station around 700kHz with a 1/2-wave tower on the "border" of the 2 conductivities may go 500 miles to the 0.5mV/m on the good ground, but only 25 miles over poor ground.)

Daytime skywave.

My best example, albeit an old one, was hearing 100% readable 4VEH, Cap Hatien, Haiti, 1435 AM with 10 kw at Cleveland Hts., OH in a winter month in 1962.

I'm surprised it only makes it that far. Maybe the conductivity map is not right?

I easily heard KFI midday up in Santa Cruz at 300 miles and the only saltwater the signal passes over is the 20 or so miles of Monterey Bay.

I've heard them midday too in summer in the central valley that far north too.

The ground conductivity is poor here compared to California and Arizona but here in Tampa at 200 miles, I can easily hear Miami's 710 WAQI battling it out with the Cubans.

When KFI was using their old tower I used to hear them during the day from just west of Phoenix to Las Vegas pretty easily during the day and this was not during the winter.
