I had a similar lack of computing power a few months ago, and my bonepile
was severely depleted and out of date. My strategy for dealing with it
might work for some of you... I went down to the friendly local beige box
dealer, handed over a $50 bill, and they handed me a big box of unknown
motherboards and CPUs and assorted bits and pieces that they'd kept from
customer upgrades and didn't have the time to test. The only conditions
were that I take ALL of them, and that they never see any of them in the
store again.
I still haven't finished testing them all, but I've got a Pentium III 550
and Celeron 466 from that batch that are running just fine. At one point I
had 486's and old SPARCstations all over the garage running assorted
services, but it's gotten to the point where I can't justify the cost of
electricity to run them all. Not sure how much my server rack is drawing
now, but it's got to be under 15 amps, 'cuz that's all the circuit will
support. Though the UPS does click on when I start the dryer...

Subject: D700 BBS

We need someone with a D700 and who has time for a test.
There is a Kenwood D700 going up to the Internatinal Space Station next
year. We need to fully understand how it works in BBS mode. It does have
an internal BBS, but like most APRS operators I have never used it, and
with me on deadline to deliver PCSAT2 I dont have time to test it myself.
So if someone has used a D700 BBS it or has the time to play with it,
your experiences would be useful. Just let us know if it works like we
normally expect a BBS to work, or if it has any quirks. If it has quirks,
explore them to the fullest. and document it for us.
THanks

Bob, is this D700 going to be used by human operators, or is it going to be
integrated into something else? I haven't used one myself, but from what
I've heard on here I'm less than impressed with their reliability...

On Thu, 1 May 2003, T C wrote advised us of the existing PACKET/Paging
system:
>http://www.mepin.com/
>this is a system that is working now!
That looks great!
But I guess what I was thinking was some "middleware" software that looked
for APRS messages to "pager users" on the APRS channel and then it
automatically contacted the nearby KPC-9612 TNC Paging transmitter and did
the "exchange" necessary to send out the page.
THus it was totally transparent to the users. And anynoe with a modified
motorla alphanumeric pager could receive APRS messages on it.
A great opportunity for someone to play with... and add to APRS..
They were selling the pagers for $xx I think, and that is cheaper than the
D7....

I'll be on the Appalachian Trail this weekend with my Daughter and will be
using APRS. I think APRS has great potential for things like this..
See my: http://www.ew.usna.edu/~bruninga/aprs-at.html
I never had a chance to follow through with all the ideas there, because
of all this satellite stuff, but at least for once I will get out of the
office on a weekend...
Ill be using the call WB4APR-7 probably...

Ok, before anyone else beats me up over this, I'm just referring to the fact
that every week it seems like someone's talking about their D700 or TH-D7
locking up, not working right in TNC mode, having to be power cycled
multiple times, dying if it hears an invalid packet, and so on. I suppose
it's a natural consequence of the added complexity... my new cellphone locks
up and needs to be rebooted once in awhile, too. But the only time I've had
a processor problem with a radio is when I accidentally zapped an Icom
mobile with static electricity and wiped out the memory.
I'm sure astronauts are more than qualified to power cycle a misbehaving
rig... but just from what I've heard here I'd hesitate to use it for a
completely unattended remote installation.

This e-mail is for those interested in attending the APRS Pizza Party.
Everything has been set up at Marion's Piazza for May 17th, from the
time of 6pm - whenever... Also this year we have a PA System so everyone
will hear us as we speak. The PA System is courtesy of Jack Parker
(W8ISH). I will have information regarding this get together, available
at the APRS Booths. If you have any question or comments before than
just drop me a e-mail.....
Thanks,

I'm curious about this. I live on the water and am always on the lookout
for MMs that might be passing by. I always check findu to see position
reports from the MM that are on Winlink. Why can't we get those position
reports put over the IS instead of just findu so I can just consult my local
APRS screen? I'm not sure where the data entry point is buy maybe Steve can
give us a few words of wisdom?

Hi Bob,
I know I have trouble reading manuals ok, :-), please point me to the
BBS capabilities of the D700. I have owned mine and a D7 since they came
out and have not seen mentioning of a BBS mode.
If you are meaning a stand-alone, I would suspect there isn't near
enough memory to operate "store and forward" type of a BBS that I am
familiar with, it's been a long time..
As far as reliability of the D700, I would question Scott's statement,
seeing as how _most_ problems posted seem to be pilot understanding, not
a rig failure.
If you intend to use a computer running the BBS software and the rig in
TNC Packet, I think it would fly..

We had this problem here on our old BBS nodes where 1200 and 9600 baud
used the same channel for communications. We tied the DCD lines together
between the MFJ 1200 and 9600 baud units to hold transmitting if either baud
rate were being received on the link.

WinLink is an incredible system for the ham in distant places, but it
lacked the web interface those left behind desired, which is why Hans,
Steve, Rick, Vic, and myself linked our systems together, it really is a
great synergy. I'd ask that anyone interesting in retransmitting the data
on APRS keep the needs of the WinLink users and their families in mind.
The position data for a WinLink user is entered manually into the Airmail
program...[Windows only |-(] ... and sent to the WinLink server via HF
Pactor. When the WinLink server gets a position report, they format a web
URL to send it to findU (unlike most of the findU accounts, I have given
them an account that allows sending any callsign, not just their own).
These reports never make it to the APRS IS. We tried it that way, but had
real problems with reliability (way back in the pre-javAPRSServ days). They
can send these reports to either of the two findU servers, every 5 minutes
the servers query each other for any direct data, like WinLink, email, or
web input.
With this entry method, these reports never appear in any APRS format, and
are never on the APRS IS stream.
So if someone wanted to send these reports to RF, they would have to
periodically query findU, convert the reports into an APRS style format,
and transmit them. This would not be entirely welcome...once the reports
are retransmitted, they would likely make it again to findU, and the
last-heard time reset. WinLink users tend to be voyagers, and loved-ones
left behind like to know that the voyagers are still alive. Many of them
rely on the findU web display to get that single bit of information, that
their voyaging loved ones are still transmitting. If someone were to
undertake such retranmission, I'd ask they include the strings to keep
findU from saving the data ("x-no-archive" or "!x!").
