AM Bandscan 530-1000 KHz

Been working on getting the AM bandscan filled out. This is time consuming duty, as many stations these days don't identify as readily as they used to. Sundays is always a good day, especially during football coverage, as they tend to identify more readily during this time.

This first effort covers 530 KHz through 1000 KHz. These are daytime loggings only, according to the rules set forth in a previous post, making sure stations are logged no closer than 3 hours from sunrise and sunset times. These loggings have been recorded since mid-October 2008.

All loggings were recorded using the Eton E1 with a 150 ft. longwire.

I thought XETRA 690 was 77.0 kW? (btw it's now XEWW, but if this bandscan was done before they changed I'm sure leaving the log as XETRA is fine.)

KFMB runs 5kW in the daytime, although I've occasionally heard them on 50kW in the mid-late morning a few times. (Even though I'm only 7 miles from their transmitter, I can tell whether they're on the 5kW or 50kW by how wide their signal splatters on a PLL single-conversion radio with a wide IF filter, or the numeric signal strength on my Tecsun PL-606 - typically around 70-73dBu when running 5kW, and 79-82dBu with the 50kW rig.
How strong is 770 KKOB there? I'm wondering if reception in San Diego might be possible, even with 760 KFMB next door? Or would I be more likely to here 770 KCBC Manteca, CA?
820 is probably either XEVMS or XEABCA Mexicali (not sure what call they use)
If 860 in Phoenix isn't Spanish language, I suspect XEMO in Tijuana, which I think runs 10kW daytime.

Have you had a chance to do a bandscan above 1000kHz? I think it'll be a challenge to ensure groundwave only reception, especially on the higher frequencies, though. (I commented about that on another post.)

Hi Stephen,

KKOB-770 is fairly good here using a 24-inch passive loop. It is inaudible without it. It might be possible there if you could null out KFMB well enough, but you may need to put some distance between you and KFMB.

No chance to do a bandscan right now. I may not get to it this winter season. I have too many irons in the fire right now.

Good luck,

Bill
