Kudos to Frank. Perhaps those that subscribe to the notion of you must
have a 6+ core dedicated beast running at 3+ gHz with 16+ Gbtye of
memory and a video card with more processing power than the Atom and
then again as much memory that take pride in <5% CPU usage with more
caches than I have sense should take note. We are the land of excess,
power to the people. Occupy Austin.

Flex-1500 Survival Kit
Need to add 1024 x 600 display resolution.
For over eight years I have lived out in a field. I have a 125
watt solar panel (56 x 25 3/4 inches) which in the summer time gives
me up to 100 watts for maybe three hours a day. In the winter time I
might get up to 50 watts for a couple of hours a day. The other day
was overcast and I didn't get above 20 watts all day long. My notebook
computers pull at least 60 watts and that prompted me to buy an
e-Machine eM250 netbook; Intel Atom CPU N270 @ 1.6 GHz; 1.00GB Ram;
32-bit Operating System; Graphics - Mobile Intel 945 Express Chipset
Family; which came with Windows 7 Starter (read - less Windoze Bloat),
which pulls around 10 watts. Running PowerSDR v 2.2.3 with Audio Pri
Buffer Size set at 128, VAC Buffer Size set at 512, and all of the DSP
Buffer Sizes set at 256, the CPU usage runs in the 60s. To be able to
see the bottom 5 or 6 lines of the PSDR screen, I have to plug in an
external monitor (read - an extra 30 or so watts that I really don't
have available).
It seems that the display resolution default is set to 1024 x
768. With 600/768 equal to 25/32nds that would leave the bottom
7/32nds hidden. My first thought was to add scroll bars, which is
better than not being able to access the bottom, but can be a real pain.
The second thought was to add a radio button in setup, (Netbook
1024 x 600 display) which when checked would add a banner, (possibly
the bottom part of the splash screen with a note stating "Netbook 1024
x 600 display is checked in Setup" so people would know why they were
getting a banner on the bottom of the display.
The third thought came when I saw that the image content didn't
change when the display resolution was changed while PSDR was running.
The image content only changes if PSDR is stopped and restarted -
indicating PSDR locks into the display resolution as it loads.
The second method might be a quick and easy way to test for a
solution without having to write a lot of code.
I know my December 2009 netbook with an Atom N270 CPU is pretty
obsolete, since the next generation used Atom CPUs in the 400 series
and the current netbooks use Atom CPUs in the 500 series. I believe
the Black Friday price for netbooks with the Atom 400 series CPU was
around $158.00 and Wal-Mart had Acer Netbooks with Atom 500 series
CPUs regularly priced at $228.00 the other day.
I know the smallest size buffer settings are probably not the
best, but I wanted to see if the netbook computer would max out or if
there would be some headroom left. I believe a netbook computer, with
a USB mouse with a scroll wheel, and the Flex-1500 would make an
excellent Survival Radio Kit.
I would be interested in hearing the results some other people
have using a similar setup. My internet connection is: travel three
miles to Green River, Utah and try to find an open Wi-Fi access point,
so I only connect once or twice a week.
To your survival,
Frank Anderson, AC0XL
