Topband: AM 1330 noise in Portland, OR

[ww3s at zoominternet.net]

	I noticed a similar problem in NW PA while trying to listen to PY0
on 1811.....I noticed something odd, when I took the cw filters out,
there was a strong signal on 1810, and when switching to AM, it was
pretty clear, it was some sort of sports talk show...I assumed
perhaps it was a harmonic of 905, but when I tuned there, nothing was
there...how can I go about finding out what this is? Anyone else in
PA/OH hear this?

 Thanks for all the comments about the noise I have been hearing. It
came
 back last night and I was lucky enough to notice it on my drive home
and
 was able to do some effective DFing (thanks for having my marine DF
receiver
 in the car).
 Turns out - it is a small AM station - 5 KW - that is generating
this 
 problem. I deduced this by DFing the station enough to rule out the 
 previous suspects - and narrow down the location enough that when I
checked
 the FCC database, it was obvious which station it was. 
 Then, I made this recording:

 In one channel - you can hear the noise on 1800 khz and in the
other, you
 can hear the station's audio. Near the end of this - you can clearly
hear
 the same modulation on the noise that is happening on their signal.
 This station is about 11 miles from my QTH. I will hopefully be
talking 
 to them today and see how quickly they will respond this.
