[Elecraft] [K2] Proper QSK delay for use with KPA500?

[Don Wilhelm]

Eric,

The KPA500 (like all other Elecraft transceivers and amplifiers) uses 
all electronic T-R switching which is very fast and there is no 
"hot-switching"

The K2 Keyout to start of RF is fixed at about 12 ms.  The QSK Delay 
adjust the trailing hold time for the Keyout after keyup, not the start 
delay.  You can run with the KPA500 set to the default of 4ms.
