I had tried to load Power SDR on my workshop laptop over the weekend and it
hangs up at initializing DSP. The computer is a 1997 IBM Thinkpad 770
running Windows 98 with 160 MB of RAM. When I go to system properties, all
it says is Genuine Pentium, not the speed. I am assuming that it won't work
with this computer?
I got everything loaded last night on our new Dell 3 Ghz machine with no
errors after having to uninstall Power SDR a few times (I must have done
something wrong installing it since I got a fatal error) before figuring out
how to do it right. Thanks Chuck Carpenter for your how to from the Sept 24
QRP-L. I am no computer whiz at all and needed a lot of hand holding here!

How much can you reduce the computer load/requirement and still have

using ?
By far the biggest portion of the computing power is eaten by the
console and graphics. The DSP is an amazingly small part of the total
computational load. The spectrum and associated display functions are
really the cycle hogs.
If you slow down the spectrum update rate to, say, 5 per second, or
turn it off completely, you don't need much machine to service the
essential radio functions. I've run the Linux version "headless," that
is, with no graphics at all, on a 533MHz Pentium.
