[App_rpt] small, durable PC recommendations

[F6HQZ]

Hi men,


I have used Soekris for an old wireless project for HAM's here in the past :
http://www.hamwlan.net/Soekris.htm
Soekris is cool with a correct temperature range.
I have played with all of their boards many times.

You can't load too much channels but it's certainly ok for a single
repeater.

Regarding low temperature, don't forget that if you start the board before
too cold season, the components temperature will be rarely under 0°C due to
their internal electrical activity.
If you put it inside a correctly sailed box, you will probably have never
issue with cold condition.
It's more difficult for hot season : you must have something to avoid a
direct vew from the sun to the box to avoid high internal temperature.
This is the first case of component destruction, not the cold !
You must also add something inside the box for the moisture and condensing
condition. Some kind of "valves" in GoreTex are perfect to extract the
condensation of water.

Good luck and have fun !

Objet : [App_rpt] small, durable PC recommendations


Hello guys,

I'm wondering if anybody has come up with a small and durable PC that
can run Asterisk and app_rpt and survive in pretty wild temperature
extremes?

We have a GE MastrII repeater up in an attic at a school and on hot
summers the temp can exceed 120 in the attic.  The repeater has
survived for many years up there, but I'm afraid your average Linux PC
would not make it long in that kind of temperature.

Also somewhat related, can anybody advise if app_rpt works on a
non-Intel CPU architecture?  I have run Asterisk reliably on MIPS and
AMD Geode but am not sure if app_rpt (or perhaps the pciradio driver)
has any particular affinity for i386ish architecture.

I wonder if I could get by with a little board like this:

ml

I'm would be grateful for your advice if anybody has looked into this
before.


Thanks everybody,
