hmm... the only thing i can come up with is the antenna wire connection...
but since you mentioned that the wire is "directly-soldered to the PCB" it might be ruled out...
although i never had any experience with ad band cars, i did however experience the same thing that you were describing in one of my am cars.... "a loooong time ago"
after checking the antenna to where it was connected to the board, i found out that it was not a good solder....
after reading some stuff, i think it was an article from draconious - that pointed out that there are other spots on the board that could provide a better reception... i tried it out and relocated the wire and viola... the reception issue was gone...
