[Hallicrafters] HT-37 CW operation

[Waldo Magnuson]

    I need an explanation of the Function and Operation switch settings 
on my HT-37 for CW operation.  I do have the operating manual and a 
schematic and have studied them.  I'm using a Dow antenna relay to a 
shared antenna.  The manual states for CW operation to set the Function 
switch to CW (that seems entirely reasonable) and implies the receiver 
will be active only on Standby and CAL positions of the Operation 
switch - which the receiver is.
    The problem is there is no key-closed output in these settings.  In 
fact the schematic shows that when the Operation switch is in Standby 
and CAL positions the key is out of the circuit (switch OS 1R).  Keyed 
output will only occur in the MOX position of the Operation switch.
    Do I need to manually switch to Standby (or CAL) every time after 
sending CW to make the receiver active?  It seems to me the Control 
Output and Dow relay ought to allow automatic transmit then receive.  
Am I missing something?  Thanks.

P.S. One of these days I will get on the air.
