    Of course the same argument could be made for virtually 
everything discussed on this list. Too old, lets just smash it up 
and dump it in the ocean.
     I am not so sure the _method_ of making frequency 
measurements is so obsolete. Comparing a well calibrated standard 
against an unknown source. Of course using a BC-221 as an 
alignment generator leaves something to be desired but, it CAN do 
a lot of the job.
    I happen to have a BC-221, a K I think, have to look. Mine is 
in a wooden case with an AC power supply in the bottom in place 
of batteries. Has a modulator. It is still surprisingly useful 
and I am far from ready to toss it in the trash. Of course, one 
must have some knowledge of history to understand what it is and 
what it does. A lot of "younger" people wouldn't know how to work 
a dial telephone if they had to so the decision as to whether 
something is useful or not may depend as much on experience and 
knowledge as on reality.
