How well does everyone receive pacific coast 50kW (and some <50k directional) AM's?

How well does everyone receive pacific coast 50kW (and some <50k directional) AM's?

(based on the NY AM stations post...)

I'm especially interested in knowing how far east you have heard Pacific Coast AM stations in their nulls, and of the ones that don't null much if at all to the east, how many of you east of the rockies can hear them...

So what stations can you guys hear from San Diego, Los Angeles, San Francisco, Portland, Seattle, etc?

In Memphis, if WDIA goes off the air for any reason, you get a faint KNX. I've heard KNX in Fayetteville, AR. Only other things I've recieved from that way are KTNN (I've heard it only a handful of times) and KSL (and it has to fight a lot of things to be heard here).

West Coast heard here:

L.A. 640 KFI
1070 KNX
1650 whatever their calls are
830 Orange Co. tentative - no ID but format matched

S.F. 680 KNBR
1640 KDIA

S.Dgo. 96.5 KYXY (yes, FM San Diego<=>Nashville!)

Sac. 1530 KFBK (big surprise!)

Spokane 1510 KGA (20mi. from WLAC, which was on at the time...)

Arizona 660 KTNN
1580 R. Disney (tentative, no ID)

KFI, KNX, and KNBR are the only three heard with any regularity.

I've gotten KTNN, KSL, and KEX each once. No sign of them before or since.

KNX would be impossible where I am in Alabama because I get both WAPI and WFLI pretty well 24/7 on 1070.

Not a thing in Ohio since I heard KFI in the 80s.<P ID="signature">______________

I heard KNX in Nashville...back in '88...just once.
I was heading to work about 4:45a, and heard traffic...and a wx
report mentioning the high desert...then KNX calls.
Haven't heard anything in the nightmare jumble that is 1070 since.

KFI from Florida before interfering 640's sign on.

In Dallas, KFI mornings before 640 in OKC signs on. KNX with extreme difficulty, I have to null KRLD. 740 from San Francisco mixed with 740's from Houston and Tulsa, but suprisingly dominant.
I have done 810 from SF in New Mexico.

How well was it coming in, and which direction was WLAC's transmitter from you, in relation to KGA's transmitter?
(I was wondering if it's at all possible to hear WJR (760 Detroit) from within 1/10 mile of KFMB's (760 San Diego) transmitter site (if you put KFMB beside or behind you and WJR in front of you, that is, and btw I picked that one cause I live close by.))

The thing is, WLAC is very directional. If you're NW or NE of the transmitter, maybe even as close as 20 miles away, you'd be in a null.

KFMB's signal doesn't have a null that sharp. Check out the radio-locator.com maps to see what I'm talking about.

I live between the two stations.

KGA wasn't by any means strong, and if I didn't have a 400-foot longwire I'd have never heard them. Still, it was relatively easy to identify.

No, unless KFMB is off the air. I have heard of stations that are so directional you can see the tower but not hear the station -- but KFMB is not such a station. In any case, 1/10 of a mile is really pushing it.

WRT the second reply, it's true, I do live in a null. That said, WLAC's nulls really aren't all that deep. (according to my calculations their field in my direction is about the same as a 1kw non-directional station) And KGA protects WLAC as well -- I'm supposed to be in one of KGA's nulls as well.

("supposed to be" as I rather suspect KGA's array was out of whack at the time)

Ok, then, how deep of a null (and/or how narrow of a lobe) could I get in a receiving antenna? For example, how far do I have to be from the 5kW omni station (KFMB daytime) to get groundwave from a 50kW omni station (WJR) about 2000 miles away? Or if I live 100 miles west of a 2.5kW station and want to hear a 50kW station 1100 miles away on the same channel (in this case 820, btw they're not directly in line with each other - draw a line from me to the 50kW and the 2.5kW (I'm guessing on their power) is a little south of that line.), could that be done with a narrow enough lobe, or even an antenna that will accept certain skywave angles and reject others and groundwave (isn't there the possibility of skywave on AM even in the daytime - you just need an ultra-sensitive setup to hear it?)
Also, now that Radio Disney 1110 KDIS Pasadena/Los Angeles is no longer C-Quam, is there a good way to set up a receiving antenna to pull in DX groundwave on KDDZ?
1670 KHPY (2nd-adjacent, but often strong signal with internal ferrite loopstick depending on conditions, 10kW directional aimed south/southwest) is 87 miles north (9.0 degrees counterclockwise from north) from me
1690 KFSG (co-channel, 10kW omni) is 485 miles north-northwest (30.5 degrees counterclockwise from north) from me
1690 KDDZ (the station I want to hear, 10kW omni) is 815 miles northeast (51 degrees clockwise from north) from me
1690 WPUA825 (co-channel, 10w TIS) is 14 miles west (96.9 degrees counterclockwise from north) from me
1700 XEPE (adjacent channel, 10kW omni) is 18 miles south-southeast (155.2 degrees clockwise from north) from me
Based on possible interfering signals being in different directionas and/or adjacent channels, is there any possible way with a good antenna to be able to pull in a usable signal off of KDDZ?
If I can't hear it 24/7, the main programs I want to hear are Playhouse Disney, Frequency Jam, and the Top 30 countdown (the Sunday morning edition).

Isn't Radio Marti's null that sharp? I thought I read here that you could be out on the Gulf within sight of 1180's towers but be out of listening range.

KOMO-AM 1000 Seattle:

How about KOMO-AM 1000 50kW DAN in the southwest Deserts? KOMO 1000 has a lobe to the southeast nightimes...in contrast to the other class A in the Seattle-Tacoma market (710 KIRO)... KOMO can be heard in Vegas but I'm not sure about AZ,NM,TX,UT,CO. Art Bell always talked enthusiastically about the huge signal of KOMO year ago when C2C moved from 5kW ND1 570 KVI to KOMO 1000. Now C2C is back on KVI. KOMO 1000 is now all news 24/7 (in collaboration with KOMO-TV) with Mariners Baseball...
