I hope that battery is rated for "c" 40A (input) ;) Comment from : Ressy6 |

I would have preferred to have seen this power supply used with a transceiver running FT8, a more real world application Thank you for reviewing this PS Comment from : Man Of Faith |
 |
When doing any kind of SMPSU review, I'd love to see a SDR or SA fired up next to it to look for RF noise You'd like to think anything made for radio would be RF quiet, but it's always good to test that it is! Comment from : Ammocraft |
 |
Sorry, this seems to be almost useless as a review No test to see if it can deliver the full rated current, no voltage drop test, and most of all for Amateur radio, no test for noise, likely the most critical test for a SM PSU for ham radio use Might as well have called this an unboxing Comment from : MrZerohour1967 |

Holy Rube Goldberg batman Gotta do what you gotta do to test it! Comment from : Ed Sai |

Thanks for the review… I always wonder when load is up what happens to ripple and does it get worse? For a simple load tester I get e cigarette nichrome and twist together about 8 strands and wind it on ceramic ( I used an old brick / ceramic house ventilation brick) I connect to it with mains cable and screw down electrician fittings … which will melt but last for one test and keep heat away from thing under test brbrRewinding a Microwave Transformer for a Linear PSU@TheArtofEngineeringbr youtube/g3ILAGc5T9g Comment from : The Art of Engineering |
