>>I found an ASTRON SS-10 POWER SUPPLY 110/220VA-12VDC 10A CONVERTER, they are asking $81
That would be fine for your present needs, but is too small for a future HF station.
>>Personally, for your application I would not use an "SS" series power supply. These are switching supplies which are small and light but more complex and can generate RF noise. I'd stick with a "linear" power supply for your application where size and weight are not a big issue.
Somewhat true, but only as a sweeping generality. I have both Astron linear (RS-35) and switching supplies (SS-30). From my own experience and QST reviews, both are very quiet in the HF and VHF spectrum. In addition, he will be currently working VHF-FM marine communications, so with FM it's not that much of an issue anyway.
That said, one advantage of the Astron Linears is the ability to easily modify them to float a gelcel battery across them to provide standby power if AC power is lost. My article on it is in the October 2004 Hints and Kinks column of QST (and the recent book).
