[K2] Proper QSK delay for use with KPA500?

[Eric Norris-2]

I will be using my beloved K2 with my KPA500 this year for SKN.  Many years
ago I put in an amp key line I think from the 160m board.  In perusing the
K2 manual, I see the QSK delay is adjustable.  What is a safe setting to
avoid hot keying?

Thanks and 73

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.
