I've used Astron switching power supplies in various applications with a
great deal of success. Cheap switchers are noted to cause problems so
don't lump "switching power supplies" all in the same bucket. There is a
big difference. The ARRL did some extensive tests on various power
supplies some time ago. In most cases, band noise and atmospheric noise is
greater than that of good switching supplies.
Linear supplies are good when you don't want the house to blow away during a
storm.

Subject: [TenTec] Station power supply??
A bit off topic but...
I am thinking of revamping my station's power supply setup.
I have an Orion, Omni VII, 2 dual band uhf/vhf rigs and assorted item that
use 13.8 vdc for running and/or charging.
I currently have 2-Astron RS-35M and 1 20 amp Astron power supplies.
I also am running a 3000 watt ups with a ton of backup batteries....this
feeds just about everything in the shack.
What I am thinking of doing is eliminating the above Astrons, getting a 50
amp plus power strip to fire the station and various sundires, or getting
a series of switching power supplies.
Qth is very quiet on man made noise.
I am aiming for efficiency, with no rfi from power supply setups, from
what I have read, the switchers are very efficient, but still generate a
bit of rf hash....I might be wrong on this.
Any suggestions or observations?
Thanks in advance de Denton, WB7TDG
