Unless you're talking about the newest array with 77kW, I don't ever
recall having problems with KFI. KMPC, on the other hand, was a
problem in the valley. We also wanted to try the opposite sideband
approach with KMPC (710) but Gene Autry wouldn't hear of it. Shortly
after I got there we hired a Consulting Engineer. I believe it was
Glenn Callison. He repaired the deteriorating array and broadbanded
it for Kahn Stereo. It really sounded great. I remember getting a
call from the GM of KHJ, Los Angeles, telling me how great our stereo
was in his office in LA with two radios tuned slightly off in each
direction to get stereo.

When it comes to antennas and patterns I'll gladly defer to Peter.
He's the man for that. I think I remember the pattern as claimed on
some promotional material which made it look like a figure 8 with the
Southern lobe pulled in.
The new owners have returned it to being a Mexican service station
and don't care, after all these years, about reaching Los Angeles. So
it makes sense that the new array favors Baja.

The FM was finally put on the air at 91.1 with 100kW from Mt. San
Antonio. Our big problem wasn't with the noncomms, it was with an
organized group of San Diego Commercial stations that filed against
us and started a campaign to discourage advertisers from going with
us. We filed a $39 million lawsuit against them. We either won the
suit or settled with the San Diego stations admitting we had the
right to sell in San Diego. Under Noble Los Angeles wasn't our
primary target. So far as I know no money changed hands. We were also
unable to get the 325B authorization to originate in San Diego.
Initially the FM was taped in San Diego and driven to Tijuana and
Rosarito by Sr. Gallegos in a VW bug a few times a day. The FM (91X)
wasn't competitive with that arrangement so the Jocks had to drive to
Tijuana to do their shows and sit for hours at the border on weekends
to get back into the US.The AM always originated (automated) from
Rosarito. The Wikipedia entry for XETRA-FM is quite inaccurate and
less than objective. It claims the Easy Listening format was changed
to AOR. 91X signed on with AOR and, obviously, never had Easy
Listening. The station didn't exist. Easy Listening was on the AM.
The listing is riddled with opinions, not demonstrable facts.
I always wondered how XETV (ABC CH 6) was able to originate in San
Diego. I understand XETV is now CW, after a time as an independent,
because a San Diego station wanted the ABC affiliation.
Mexico would let us do almost anything. That may have been due to the
friendship between Ed Noble, who lived in Mexico City, and President
Jose Lopez Portillo. As I recall, we figured it would be cheaper to
run our generator 24/7 than pay the Pemex price. At the time, I'm
told, it was illegal to take yourself off the grid for more than
emergencies. Even the President didn't go for that one.
I've gotta tell ya, it was a fun time.
