[BC] "Mixing Product" for all you smart engineers...

OOOPS! Hit "send accidentally - sorry about that!  Moderator feel free

Anyway; 1590 - 1230 = 410; easily within the realm of the IF passband on 
many, especially older, radios.  So, sounds like the nearer signals may 
have momentarily swamped the radio - especially if the Desired Signal 
happened to get nulled by some external factor, such as overhead power 
lines.  You don't mention the distance to the desired 1230 signal, so 
that's an E-WAG (educated W. A. G.)

I've received unknown DX before last Christmas every morning while 
traveling alongside some 135 KV lines with the radio on 1070 - and being 
toward the western edge of the pattern (at about 5:00 am; with 1070 on 
the tighter 6-tower pattern and at 10 kw).  Never had time to stop and 
try to ID the Undesired Signal, but it sounds similar.

Other possibility is someone's pirate TX relaying WCRS for some reason....
