For those of you in the Realms of the East who are searching for the West...
Here's a recording of KNX 1070 Los Angeles, CA, including the traffic sounder.
This was recorded this past summer (July 20, 2010) shortly after 4pm in my back yard, using the Tecsun PL-380 and Select-A-Tenna. I'm about 111 miles from their 50kW transmitter at a heading of about 315°.
A few minutes before I recorded that clip, I
recorded a minute or so around TOH, including ID, in the house with the Tecsun PL-380 using only its built-in ferrite antenna.
Also, IIRC, their music bed they use at BOH should stand out, as well. I'll try to record that in a few minutes (if I remember

) and post it.
Good luck.

Bonus points for digging it out with the quality of signal that I can hear it in the daytime.

BTW in some places like the eastern USA, is that the typical quality of reception of a 50kW at about 110 miles above 1000 kHz (for example, WBZ near the MA/NY border, WBAL in Richmond, VA, or WINS in Albany, NY)? Or do you have stronger signals (or weaker) at that distance there?
I maybe should mention that there is some saltwater in the path between me and KNX. I've also noticed that KFI is slightly weaker, in spite of being on 640 and 12 miles closer. Could it be the lack of saltwater between me and KFI? They're a bit more inland than KNX is.
