[TVARC] 12V DC 20A Switching Power Supply recommendations

[Anthony Hackenberg]

Hi Larry/K4LES,

My favorite (and current) power supply is MFJ’s Model#MFJ-4245MV.  It’s been a great performer for me over 10+ years (without any hash, or other, interference).  Here’s MFJ’s webpage for this specific power supply:

https://mfjenterprises.com/products/mfj-4245mv

Of course, you can also get additional reviews of that power supply, and other ham equipment, online at eHam.net (URL/link: https://www.eham.net ).  I think you may have to be a paid subscriber to access eHam’s reviews.


Stay safe from COVID-19 😷 💉💉  


73,

Tony/K4QR

Had an open-frame 50A switcher years ago out of some unknown surplus equipment that generated S9+30dB square wave noise from 60 Hz to about 900 MHz, put me pretty much all the way off of using SPS's at all, but need to reconsider due to size constraints on this project.
