[Elecraft] [KPA500] Rear power switch thread

[Oliver Dröse]

Hi Ron,

the arguments are told over and over again ("it is like a computer, etc.") 
for the K3 and KPA500. Still I do not see WHY it is possible with every 
other transceiver and PA on earth to simply shut down power (disconnecting 
from mains) without first switching it off and without any possible 
problems? They use the same "computer technique" inside ...

Just curious. ;-))
