In my haste to work through about 180 incoming email messages this 
morning, I managed to erase the post about the problem on 1827.

In the USA, AM stations are spaced by 10 kHz.  Recently, there was a 
long discussion on the Reflector on intermodulation problems, 
producing garbage every 10 kHz.  

In the rest of the world, AM stations are spaced by 9 kHz.  Exactly 
the same effects will happen, with garbage on multiples of 9 kHz 
(1818, 1827, 1836, 1845 kHz).  This may well be the answer to the 
problem.  Use the same solutions (band-pass filters, high-pass 
filters, or even some of the more esoteric solutions like tube 
amplifiers, pinches of moonlight, the shadow of a black cat...).
