SETTINGS, AND RECENT TEN TEC TRANSCEIVERS HAVE A SINGLE 15 MS FIXED DELAY.
SOME ICOM RADIOS SUCH AS THE IC 7300 AND IC 7700 HAVE ADJUSTABLE DELAY FROM
10 TO 30 MS, BUT OTHER ICOM RADIOS HAVE NO DELAY ADJUSTMENT AT ALL.  I
MEASURED AN IC 706KIIG DELAY AT 12 MS AND AN IC 7000 DELAY AT 8 MS,
VIRTUALLY ENSURING HOT SWITCHING WITH MOST NON QSK AMPLIFIERS.  FURTHER,
MANY HAMS OPERATE FULL BREAK IN QSK CW DURING CONTESTS AND DX CHASING.
WHILE MOST CURRENT HF TRANSCEIVERS WILL OPERATE FULL BREAK IN, ONLY HIGHER
END AMPLIFIERS HAVE THE SWITCHING COMPONENTS CAPABLE OF THE SPEED AND
SWITCHING RELIABILITY NECESSARY FOR FULL BREAK IN OPERATION.  AND TO
COMPLICATE THIS FURTHER, SOME TRANSCEIVERS UNKEY THE AMPLIFIER BEFORE RF
HAS COMPLETELY DECAYED, WHICH CAN CAUSE HOT SWITCHING ON UN KEY.  EXTERNAL
