[Elecraft] KPA500 Questions...

[Mike K2MK]

Hi Phil,

I'll give you my opinion and I'll also assume that you are talking about
your home shack and not a KPA500 that is operated remotely. I don't even use
STBY. I have the menu set for the KPA500 to go into OPER on power up. When I
don't want to use the KPA500 I just hit the power button to turn it off. The
KPA500 is instant on so I don't see a lot of difference between STBY and
OFF. I don't own a KAT500 so I don't know if my opinion would differ if I
did.

I wouldn't think leaving the KPA500 turned on for long periods of time is
any different than leaving the K3 on for long periods of time. I suppose
some aging occurs and of course power is consumed.

73,
Mike K2MK
