DELAY THROUGH THE MENU SYSTEM.  WHETHER OR NOT YOU OPERATE FULL BREAK IN,
HOT SWITCHING OF THE TRANSCEIVER OUTPUT, THE AMPLIFIER OUTPUT, OR BOTH, CAN
OCCUR IF THE TRANSCEIVER RF OUTPUT OCCURS BEFORE THE AMPLIFIERS TR RELAY
HAS COMPLETED SWITCHING.  HOT SWITCHING CAN BE HARD ON THE TRANSCEIVER OR
AMPLIFIER FINALS AS THE EQUIPMENT CAN SEE A MOMENTARY HIGH SWR DURING A HOT
SWITCH EVENT.  IT CAN ALSO BE A SOURCE OF KEY CLICKS ON CW WITH QSK CAPABLE
AMPLIFIERS IF THE TRANSCEIVER HAS PREMATURE UNKEY/RF TIMING.  FIGURE 4
SHOWS HOW THE SEQUENCE OF TIMING EVENTS SHOULD OCCUR.  SOME EXAMPLES OF
TRANSCEIVER SWITCHING TIMES YAESU TRANSCEIVERS HAVE A DEFAULT AMP KEY TO RF
OUTPUT DELAY OF 5 MS, THE ELECRAFT K3 DEFAULT DELAY IS 8 MS, AND KENWOOD
RADIOS HAVE A DEFAULT DELAY OF 10 MS.  YAESU AND ELECRAFT HAVE VARIABLE
DELAY MENU SETTINGS THAT CAN ACCOMMODATE VIRTUALLY ANY TR DELAY
REQUIREMENT.  RECENT KENWOOD TRANSCEIVERS HAVE FIXED 10 MS AND 25 MS
