    I worked at Motorola and adjusting the trimmer for the antenna at 1400 Kc was necessary for good performance. Different models had different tune up points. Some were 800 kc and a few down at 600 kc. Depended on what car model it was to be installed in and also if it was for Ford, Chevrolet, or Chrysler.
    A short FireStik might work really good for late night DX am.

    A simple am/fm preamp works great in those fringe areas, thier about $10.0
    All over eBay or Wal-Mart

    Never saw a preamp for both AM and FM. Lots around for FM and TV however. Most of them have ZERO filtering however and will overload VERY easily if anywhere near a VHF transmitter. Been there and had one....or two.....or three and been there done that on the causing overload too. LOL
