45 degrees is not particularly cold; I wouldn't expect any power supply to have problems at this temperature. It's easy enough to test: warm it up, check the voltage, cool it down, check the voltage - repeat a few times to be sure that the temperature is the cause. Your fridge can do double duty as a test chamber. > need another supply for the K2.

As Don already said, you don't need a power supply hooked up to the K2's power connector, only to the KPA100's. If the exception that Don mentioned applies to you (KPA100 in separate enclosure without a DC connection to the K2) then you could connect the same supply to both. -- 73, Brian VE7NGR _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
