[PCR-1000] PCR-1000 Front end overload

[A10382]

A recent issue of QST (ARRL's monthly magazine) had plans for a lowfer
pre-selector & antenna.  It was easy to discern the coil dimensions,
inductance values, and cap values for each portion of the band below
1700kc...

Sooo.. it would be relatively easy to make a band pass filter using the
values noted for each desired segment of the MW and LF bands.
