[SMCARA] Used Power Supply

[Tom Clarke]

A 12 volt battery will work for a while,  but most HF rigs go a bit 
daffy as the voltage sags.  You may get an hour or so out of a fully 
charged battery.

If you operate the rig with the trickle charger on the battery, you will 
windup with hum on your transmitted signal.  A trickle charger will also 
take forever to recharge a depleted battery.

Look for an Astron 20 or similar.  Some surplus houses sell switch mode 
25 amp supplies that will do the trick.

I have an old Bullet 25 amp linear type power supply that probably 
qualifies as the ugliest PS in the county (possibly on the East 
Coast!).  It is yours for the asking!. You could even fashion a cabinet 
and it won't be ugly anymore!  If you would like something nicer, I do 
have a Heathkit HP-1144 22 amp 12VDC supply for $50.
