I would like to hear from anyone who has attempted to use one of the small external PC AC adapter power supplies with a K2. They are, of course, switchers, so I am not very hopeful. I have found a couple of possible candidates, one a Meanwell P40A-4PSJ rated at 13.8 volts at 2.66 amps and the other an APS AD-740U-1138, rated at 13.8 volts at 2.8 amps. They seem to have somewhat comparable specs as to regulation, ripple, and protection. I suspect they would be pretty bad on RFI, so even though they can be had cheaply, they may not be worth the grief. My fallback position would likely be the little unit from Gamma Research, HPS-1a, but that will be twice as heavy and probably ten times more expensive....but from what I've read about it, it is not very noisy electrically. I would really appreciate any thoughts, especially those with first hand experience. This would only be for portable operation, not "normal" use. Thanks.
