Hi we just got QRV on 160 right before the SP and noticed AM BCI at 1800 kHz 
and every 9 kHZ  up from there. Since 9 kHz is the BC channel spacing here I 
suspect two adjacent stations are mixing. Somehow somewhere. Maybe here in my 
station, one of the BC stations or somewhere else?
Unfortunately our new HiZ 4/8 array was rendered inop before we could finish it 
due to rodents chewing away sections of the feedlines. We rigged up 2 2-way one 
wave Beverages and these heterodynes were the same strength from all 4 
directions on them. Opening our tx vertical had no effect.
Anyone know the likely cause/cure for these observations?
