Tim, I have 3 of the Alinco DM-330MV switching power supplies. They are rated 32A peak, 26A cont. Most of the switching supplies have a side-effect of generating RF hash, but the Alinco's are dead quiet in that respect.
I know -- you were talking about fan noise. The fan on the Alinco is also quiet. I will admit that the bearings in the fan of my oldest supply are getting a bit noisy, but it has been on 24/7 for 7-8 years. It is about time to spring the $20 to get a new fan....hi..hi. The Alinco supplies are adjustable over a greater range than you specify as well as having a preset value (which is also adjustable). The Astron supplies you mentioned are linear supplies and are not adjustable. They do not have fans, so they are dead quiet in their operation. By-the-way, I would not recommend the RM-20. 20A is a bit light for a 100W radio. The RM30 would be a better choice. 73, Ray, K9DUR http://k9dur.info _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
