[Boatanchors] Schematic for Becker Mexico 611 car radio?

[kd4e]

I need a schematic, and preferably other service info,
for my recently acquired Becker Mexico 611 car radio.

The receiver covers 145-300KHz, AM-BC, a segment of
shortwave around 40M, and FM.

I'd really like to get it working for the car.  It would
be especially neat to monitor 40M while driving around,
it may help to get our 12yr old to upgrade to General and
our 10yr to try for her license again.

Is anything interesting on VLF for which a car antenna would
capture enough signal above the noise floor to hear it?
