All: Has anyone tested the latest Astron switching power supplies for noise? I read a few reviews that said the new units produce no noise on HF. https://www.dxengineering.com/parts/asr-ss-30m Tony _

I had the SS-30 (no meters) in the '90s. No formal testing, just observations. It was RF quiet, I mostly used it on VHF but at least once on HF. It had a regulation problem if RF was in the shack, su

Recently I bought a new 35M....works great. I thought about getting the switching unit but I did not want to take a chance on any RFI. I did not read any reviews...experience varies. 73 David Harmon

Imo, linear power supplies are still the best. Case in point, my Astron RS-35m has not missed a beat, it was the first purchase I made when I passed the technician(c) exam in 1968. To this day, it co

"Imo, linear power supplies are still the best....my Astron RS-35m....Nuff said here about that." Not quite... Astrons, from the 90's onward, were notoriously bad... I have a pile of bad ones. Not a

I have an Astron SS-30 (no meters) switching supply. Its RF silent; the fan makes some noise but its quite tolerable. I also have an old Astron RS-35 (no meters) linear supply. I tossed the Astron re

I've been using a Samlex SEC-1235M for years. I've never detected any RFI from it. Linear supplies, while they generate no RFI, have a particularly nasty, and common, failure mode. When the series pa

A likely cause of the RF issue is that in every Astron I've opened, the foot of the terminal strip to which both V- and Green Wire are soldered was insulated from the chassis by paint. This makes the
