[AMRadio] SB-221 to SB-220 Conversion

[rbethman]

  No question that an SB-221 can be converted to an SB-220!

The ease is dependent on the year of the kit.  The later the manufacture 
date of the kit, the MORE difficult they made it to convert.

I know my SB-201 was from the mid '80s.  It was harder to convert than 
the "earlier" ones.

The FCC clamped down tighter and tighter as the time passed.
