Hearing San Diego radio stations in Los Angeles

I don’t think so? I’ve only popped it on when I’ve been knocking around the kitchen and it’s been en español all week. I know what you’re talking about and I feel like I’ve heard that programming on 91X early in the morning before, but what I’ve heard has been during the day
Interesting. Unless you're picking up a different Mexican station on the same frequency, the only possibility I see on radio-locator.com is https://radio-locator.com/cgi-bin/pat?call=K216EM&service=FX. It is supposed to be a K-Love affiliate, according to them, but I wonder if that information is out of date.
 
This is a good example of what I have heard a lot of DXers say in recent years: Translators, by squeezing onto every viable frequency they can find, have essentially ended FM long-range listening.

Of course, full disclosure is warranted: The stations I program or consult in New Mexico are largely AM/translator combos, including the one I program directly for them, KRKE Albuquerque.

And @Jstnpspck's experience, coupled with the typically simplistic map from Radio-Locator, does prove that a low ERP at a high elevation does result in a wide signal footprint; in ABQ, pretty much all of the translators -- including KRKE's -- are up on Sandia Crest, which overlooks the Albuquerque metro, and 250 watts at that elevation with no terrain obstructions is roughly equivalent to a full Class A.
 
Has K216EM increased power, or were they off air for a bit recently? Even with the skies clearing they’re still drowning out XETRA for me at home and also while out driving today; I don’t think I’ve heard them this strong in a while.
 
Regarding 91X, I recall being able to clearly receive the signal day and night in many parts of LA and all the way up to Santa Barbara in the '80s and '90s. Today, you can pick it up in selected spots along the coast, but the reception can be spotty and is nothing like it was 30 years ago. Was 91X forced to power down? Recall that AM stations in Mexico, at one time, used to blow way past the 50,000 max signal that the U.S. maintains. Assume some FM stations also sent out a much stronger signal than what the U.S. allowed. Any insights on this?

This is a good overview of how the noise floor has been increasing over the decades, it mainly affects AM but can affect FM too:

A couple of reasons, which have already been mentioned but are probably worth reposting together:

1. When non-commercial KCPB (now KDSC) signed on from Sulphur Mountain near Ojai in 1980 on the same 91.1 frequency, it eliminated pretty much all of the coverage area for XETRA-FM in both Ventura County and parts of Santa Barbara.
2. There is a translator which is also on 91.1, K216EM, which is on Mount Wilson and aimed at the Los Angeles basin. That pretty much wipes out the signal from Tijuana along the coastal communities from Santa Monica down to Long Beach, as well as the city of L.A. proper. The only area not affected by the translator -- which began operation in 2003 -- is the far west part of the San Fernando Valley, which is terrain shielded from 91X anyway.

As far as I know, XETRA-FM has been at the same 100kw ERP all along.

Hope those provide some useful insights for you.

91X is very audible in the eastern San Gabriel Valley. When San Diego is booming in, 91X cleans K216EM's clock here. And even when 91X is only coming in at moderate strength, I can often toy with the capture effect by rotating a portable radio in my hand to instantly flip back and forth between K216EM and XETRA.
 
The San Diego stations are also regulars on the beaches of Santa Barbara. They travel nicely over the water.

I used to enjoy listening to San Diego stations during my UCSB years (1983-87).

San Diego also came in well when I was living in West Los Angeles (Palms area, near the 405).

I have a bunch of airchecks from those years that I really need to sit down and digitize....

Did you ever listen to The Mighty 690?

They came in really well when I lived at UCLA dorms as well

I agree. In NE Ohio, used to be able to pick up WDVE out of Pittsburgh, roughly 120 miles from my location. Not anymore as there is a translator running a "Christian Contemporary" format in my area now on that frequency.. There's a few others I can't recall off hand but when I tuned into their frequencies there were either translators or LPFMs wiping the distance ones out of the ether. I can only hope for DX.....which actually happened a couple of weeks ago. Local station [91.3 with tower fairly close to me] was almost unlistenable so started dialing around. Seemed to be picking up stations way to the southeast [like West Virginia, Pennsylvania and some Maryland stations] a few to the southwest and south. Didn't last very long about 2-3 hours.
 
Well Before the Digital age and this HD stuff It was fun to listen to far stations, I could hear 90.3 and 91X almost everywhere in the San Gabriel valley / Pasadena. Also I use to get many stations from the Ridgecrest area, NOT ANY MORE thanks to HD

I don't think it's as much HD interference as it is the increase in translators. (In fact, if you go back several posts -- to #50 -- I already identified the translator that is on 91.1 from Wilson. HD has nothing to do with that.)

Remember, the FCC doesn't care if a station is heard outside of its licensed, protected contour.

I just noticed that EMF moved 91.1 to where 90.3 used to be before they gave it away.
