KPA500 Questions...

[Phil Hystad-3]

I have two questions (slightly related) about the KPA500.

Question 1:  Assuming that there is no transmitted signal at all, is there any difference in whether a KPA500 is switched into OPER mode or STBY?  Does OPER mode, even though the KPA500 is not actually being used, draw more power are there any other reasons to make sure that the KPA500 is in STBY mode unless it is being used.

Question 2:  Is any harm caused when a KPA500 is left in OPER mode for long periods of time though idle?

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.

If you lived in California, you would think differently about that.
Thanks to the crooks at Enron, our differential rate is currently $0.36
per kWh, and that's year round.
