DRAKE 2B`

[Garey Barrell]

Bob -

OK.  I guess it's a matter of what you want to do.  The MUTE circuit is 
the same as the typical receiver of the day, i.e., the MUTE terminals 
are just in parallel with the front panel switch.  So to use the 
receiver by itself, no connection is needed.  Typically, the MUTE 
terminals are wired to a pair of contacts on the transmit relay, and the 
switch is left in STANDBY.

The later Drake receivers all used a rotary multi-position switch, and 
the MUTE line had to be grounded for the NB or CALibrator to work.
