Wow, that does sound like a nice catch. :)
I wonder if I'd be out of luck trying to get that from here on the west coast with a barefoot unmodded PL-380. I live within a few miles of a 50kW (at nighttime) blowtorch on 760, KFMB. Even in the 1kHz mode on the PL-380, splatter from 760 doesn't really disappear until I'm about 13 or 14 kHz or so away from the assigned frequency, even though KFMB doesn't use IBOC. Maybe I should attempt to "cheat" with my Select-A-Tenna.
I can't even seem to get the TPs on 747 and 774, either. :( Also I have yet to have any luck getting the TP on 594. I'm 10 or fewer miles east of a 5kW station on 600 that runs the IBOC hash.
Right now, though, my PL-380 is semi-nonoperational. I had busted off the tuning knob, ordered a new part, and now with the new part in, it won't tune the radio. The arrows in the display will light up as if I was tuning, but the numbers and station won't change. Also I'm going away this weekend so it may be a while before it's fully back up and running (although I may patch it together enough to use the keypad to tune it while I'm gone this weekend). BTW, it's a 11-2009 model, and while I'd like to do a good quality stealth loopstick mod (I liked one person's idea of putting it where two of the batteries normally are), I'm holding off for a little while for now, at least until more info comes out on how effective various types of transplants are. :)
And, with John Bryant's recent passing, which I'm deeply sorry happened, I can fully understand extended delays in continued research in that area.
