[Elecraft] KPA1500 duty cycle

[Erik Basilier]

A recent Elecraft newsletter stated that "the KPA1500 is a high duty cycle
amplifier compatible with most digital modes ranging from RTTY through JT65
etc.". The KPA1500 manual specifices  for 50 MHz "Maximum 50 sec key down /
50 sec standby (Rec. Min Fan Speed set = 2)".

My question: For the 50 MHz scenario of alternating 50 sec carrier and 50
sec standby, how much testing has been done? Has anyone run this way for
days on end?
