Solid power Supply - no hash - some audible fan noise			Time owned: 0 to 3 months
Having used other switching power supplies I can say that the PS-125 generates no hash that I can find and I spent hours searching for it, whereas I was able to find it on others quickly (Samlex SEC-1233 particularly). So from the radio's perspective this power supply is very quiet. Voltage drop at full power draw was only 0.25 volt so it is very stable whereas others I've checked in the past can drop more than 1 volt. The fan does come on quite a bit and mine does have a high-pitched hiss when under load, even though the unit never gets warm ot the touch. I solved the audible noise by cutting off the short power lead and extending it to 6 feet and then I put the PS-125 under my desk. Now it's no louder than my PC (which is very quiet) and I no longer notice it. What I do notice is absence of hash when tuning around the bands. With band condx being what they are who needs hash noise in the mix?
