Why do people run unattended? Are there *good* reasons for keeping a
fixed/home station going 24/7 when it's not giving important information,
such as "I'm here .. talk to me"?
Maybe the problem is that we have too many unatttended stations. To save
energy and reduce traffic, maybe we should consider urging stations to shut
down when they aren't really doing anything. After all, wasn't APRS supposed
to be a dynamic system?
I don't leave my computer running 24/7, so when I shut it down, I shut down
APRS. (And I used to send out a STATUS beacon that said "QRT now" when I
did -- I need to get that going again.)

PCsat got overloaded over the weekend and reset. We tried several times
over the weekend to recover, but so far, no luck.
Today, on an optimum pass at 1415z Tuesday, I was able to turn everything
off including digipeat as a last ditch effort to see if we can recover
her. I set her callsign to NODIGI so you will know why she is mostly
silent.
Best way to use PCsat without fear of damaging her is to use the UNPROTO
APRS VIA WIDE. That way, if she can support general digipeating, we will
re-establish the WIDE alias. If she cannot support it, then we will
not activate WIDE and you are doing no damage.
And of course, dont send any packets to PCsat in the dark.

Besides my IGATE, which beacons for obvious reasons, I leave Xastir running
full time. That way I can check in and see what's been going on with the
local area and have tracks and such that a history feed won't provide.
Usually I remember to have 'disable transmit' checked, but every once in
awhile I'll uncheck it to talk to someone and forget to check it again.

i was keeping my home station running 24/7 until the computer's power
supply smoked. when i put in a new supply, it'll go back on 24/7...
why???
not so people can find my house! they either know where it is or don't care
(usually both <g>..)
however, i use the heard screen to find out when the truely unattended
(remote) digipeaters are inoperative and how long they've been that way. if
we had a bunch of retired people who were always using/monitoring aprs i'd
get a phone call immediately, but there are only a couple of us who can
"spell aprs" <G>.
in addition, my digipeater allows a "previous packeteer" (i think he's quit
packet...) to get into the lan with his lousy equipment from his lousy
location.
if i lived in an area where there are a lot of digipeaters/nodes (which may
be ralph's case), i'd certainly be following ralph's example.

I'd like more input for my "APRS Client Capabilities" chart: What
emulators are required in order to run various APRS client applications on
"foreign" operating systems (operating systems they were not written for)?
The latest chart can be found here:
http://www.eskimo.com/~archer/aprs_capabilities.html
It's also linked to the Xastir "Features" web page. If anyone else wishes
to link the chart into other APRS web pages, please do so! It does no good
if nobody sees it.
I know of these OS/Emulator combinations:
OS/Emulator: Lets you run:
----------------- -------------
Linux/Wine ??
Linux/VMWare APRSdos,APRS+SA,APRSPoint,Ozi-APRS,UI-View16/32,WinAPRS
Linux/DOSemu APRSdos
Linux/POSE PocketAPRS
MacOSX/Virtual PC ?? (Same list as VmWare above?)
MacOS9/Virtual PC ?? (Same list as VmWare above?)
Windows/Cygwin Xastir
FreeBSD?
Solaris?
Others?
I'd prefer hearing from those that have gotten working configurations under
any of these emulators. Xastir under Windows/Cygwin I know a bit about,
the others I don't.
Can anyone provide further info? Thanks!

Well, mine's an igate.
The EOC station is up all the time (or should be) and usually unattended,
but when the hazardous waste hits the impeller, I want everything up and
ready to go.
I agree, for a non-igate, non-eoc, non(whatever) plain old home station,
pretty much all you're accomplishing is "hey, you're not the only guy in
the county on APRS", which is maybe becoming less useful in some areas.

The "value" of the network is proportional to the number of stations on the
air (correctly configured of course) and number of participants. A station
turned off is a loss to the network.
Same applies to legacy packet...
Speaking of the attended/unattended issue; Aprsplus has a feature that
might be useful as an example. If the status line has "ECHOLINK=" and
echolink is on, the program will automatically display:
ECHOLINK=YES
If echolink is not running, it displays:
ECHOLINK=no
So we could take an example from the Instant Messaging applications
and have tags for:
STATUS=WANTTOCHAT
STATUS=ONLINE
STATUS=AWAY
STATUS=DONOTDISTURB
STATUS=URGENTONLY
STATUS=NOTAVAILABLE
So folks that wanted to chat, or were avaliable only for important
messages, could easily broadcast that info.
Just a thought...
