[Boatanchors] Testing Unknown Mechin

[Al Klase]

Hi Jeff,

I'd start by connecting the RF generator to one end and a scope to the 
other.  Sweep by hand looking for output.  If it's a mechanical filter, 
I'd be looking below 1 MHz.  Once you've found the center freq., you can 
sweep it to determine the band-pass shape.  You'll need to sweep slowly.
