It should also be noted that the transmitter dynamotor runs only
when the transmitter is keyed, when in VOICE mode. Thus K-52 is
not too important...there won't be any HV from the dynamotor.
But in CW or MCW mode, the transmitter dynamotor runs continuously,
even in receive. K-52 interrupts all HV to the transmitter
until the transmitter is keyed.

It may be of interest that this is a switch that is NOT on the
receiver or the transmitter. It is an external toggle switch
typically mounted through the operating desk top near the BC-348-*,
usually near the right side of the BC-348-*.
