Which power supply?

[Oatmeal]

I no theres alot of different PS's out there, just curious what one you use with your hf radios ?..

 

[wavrider]

best bet is to get one that has some headroom, if your rig draws 20 amps then look at 30 amp supplies.

Astron 70 amp regulated power supply is what I use. They are big and heavy well known and used in the Amateur community.

I use it for my HF station and it easily powers my Kenwood TS590 and 400 watt amplifier and auto-tuners and other low amperage accessories.

A 35 amp is all you need for a 100 watt HF radio with a little amperage to spare.

The most important thing to look at is the power supply's continuous rating rather than the peak.

Astron's 20 amp power supply for example peaks at 20 but the continuous rating is 16 amps. That's a little shy to run a 100 watt HF rig. My 70 amp peaks at 70, but the continuous is only 57 amps.

Seems like you get cheated but that's the way power supplies are spec'd and sold.

For a base station an Astron 35 amp LINEAR
supply will be fine for your HF 100 watt radio.
Mine has performed flawlessly for 20 years.
Don't take a chance on any switching supply
which may be a noise source on HF bands.

Buy the biggest you can afford is the best advice I can give. Everybody ends up adding gear in the future.

In ireland almost everyone I know runs a watson 25 amp linear supply http://www.eham.net/reviews/detail/6932 35 amp versions of the same are popular also.

Astron 35 and astron 70 both Hold at their full amps after a little mod

What kind of mod and at what risk to the power supply components?

For HF I have an Astron 35M and for my VHF amplifiers the Astron 70m.

Get a computer server power supply off eBay. Get more for less than buying any off the shelf unit. 50 amps for 15-20$. How does that sound?

I use a Tripp-Lite PR50. Serves me well.

astron 50M here for the ranger 2970N2

Love love love my Iota's. DLS-55's here. Can't go wrong with an Astron, either. But Klondike Mike offers up a great and inexpensive alternative. I have looked into this myself, but have yet to take the plunge.

Astron 50 and Astron 70. Also have a triplite 40 converted to 60, EF Johnson repeater supply.

I went down the path that KM talked about. 43 amp 12.8 v for about $15. I switched it and set the voltage to 12.8 vdc. works great and I have not noted any hash yet.
