[NLRS] Power supply question

Mon, 26 May 2003 11:08:27 -0400

I picked up a Samlex SEC-1223 supply in Orlando last week.  It weighs 
less than my 706 for about the same footprint, which makes it great for 
portable operation.  It is rated at 23A continuous/25 peak, and I 
actually believe it.  I tested it with the IC-706 at full power for 60 
seconds and the fan didn't come on--it got warm, but not very!  If you 
are going to use it at full-duty cycle above 20A, you might want to add 
some fans just to be safe.  As for RFI, I would call it unacceptable at 
160/80m because of loud spurs ever 20 kHz or so, but I couldn't hear it 
above 20m with my outdoor dipole, and it was dead quiet on 2/6.  Might 
be worth looking into.  I got it for exactly the same reason---I got 
sick of paking my 20lb standard supply in my baggage!

I have a RS-70M at home in Nebraska.  It has stayed on the shelf where I 
put it 6 years ago.  I think it will be there when archiologists dig it 
up in a million years--there's no way in heck I'm going to move it.
