[IRCA] KHAC 880 [ Dysfunctional Carrier + USB ]
Congratulations to Brian for his two new logs on 880 AM. I think we can
all relate to two hours of careful listening, tuning, and nulling. :-)
One part of his message that caught my eye was the mention of KHAC, My
primary DXing interest is in domestic stations, with an emphasis on the
Western states. Basically any station with a "K" call sign gets my
attention.
Brian described the signal from KHAC as being "dysfunctional carrier +
USB Signal". That got me wondering if the signal might be easier to
identify on a waterfall display such as on an SDR receiver? Anything
else that we could look for here in the East to help identify this small
station from Tse Bonito, New Mexico.
I see they're only running 430 watts at night. Any chance that their
automation fails from time to time?
With all due respect to Hector Urquhart, "One's man's annoying local is
another man's DX"--or words to that effect.

Not only does KRVN bomb in this way, but KHAC with it's dysfunctional
carrier+USB signal is often just as strong. I've found it very difficult
to simultaneously null both out with just my tuned loop, or phase both out
when adding in the vertical. But, I happened to notice last night that
KRVN was totally dominating at 11:40pm MST and when phasing it out I still
wasn't getting much if any KHAC. The Clark Howard show was playing and the
only two listed 880 affiliates were KRVN (definitely not playing the show
then) and KCMX. I was also getting two stations with Mexican music at
times.
To make a long story short, with very precise phasing and 2+ hours of
precise listening, I was able to double my 880 kHz logs and record call
letters for both:
880 KCMX, Phoenix OR, very weak at 1:33am, 1000W, call (new; phaser)
880 KWIP, Dallas OR, weak at 2:00am, 1000, call (new; phaser)
KWIP was one of the ones with the regional Mexican format, I think the
other one was a Mexican station that I keep not being able to formally
identify, maybe XEPNK. KHAC seemed to progressively come back through the
morning, so I'm not sure if propagation was just unusual as opposed to them
having a problem.
