A cross between AE5PL and N8SM does not really show any links between
the two other than they both live in TX.
Hopefully he is away on business or vacation and that is why we have not
seen any comment.
The ARRL letter goes out on Friday and the last message I have saved
from the sig from him is on Saturday.

People
I am seeing some strange data from some D700 station... Very strange. The
data looks slightly corrupt, but it appears that the GPS is working
correctly.
In the first case, by my calculations his car has travelled 10390 KM in the
last 90 minutes... Which I suspect is a land speed record for a Toyota
Landcruiser... In one case the GPS set the position EXACTLY 5 degrees west
of where it should be... In the other case it was EXACTLY 36 degrees north.
Now, my own car had a simiarl problem today... It suddenly moved from 150
degrees east, to 140-something.... For one packet.
I do not think that it is an incorrect decoding of the MIC-E string...
Decoding by hand indicates that something is wrong.
There are three failure mechanisms that I can see
a) GPS Failure
b) GPS serial corruption
e) TNC fault
GPS Failure.
Given that the coordinate are off by EXACTLY a few degrees this does
not seem likely. Any multi-path would tend to be off by non-integer degrees.
I am discounting this.
GPS Serial Line Corruption.
In my case I am using an AISIN with a Byonic GST-2 converter. I am
not using any level conversion hardware, so I am outputting at 0-5V instead
of RS-232. It is strange that the integer Lat/Long only seems top be
affected... Or is it that corruption in the rest of the packet would cause
it not to be seen, or not recognised
TNC Fault
This is intermittent... I hope this is not the fault...
In the first corruption; The way that MIC-E stores the longitude is as a
single character - at least for our purposes. The value of the character
went from 0x75 to 0x70. For the Lattitude the double-byte went from 0x5358
to 0x525A
In both cases it was two bits on the serial data stream that was
corrupted... In the first case two bits went missing... And in the 2nd case,
one bit went missing and one bit was set.
This is strange... Anyone have any good ideas?
Darryl
P.S. I don't know if it is still doing it, but I put an odometer on the
VK2RAG-1 repeater yesterday... My software stopped counting at about 360,000
KM during the day - which I think is a hard limit on the odometer... Turns
out the repeater had two sets of beacons set - one for 33 degrees North, the
other for the same position south... So the repeater was jumping arround a
bit

Rumors of my death are a bit premature :-) N8SM (Steve Miller) did meet
an untimely death Sunday before last. I was helping make sure that
Steve's widow was being taken care of by Steve's ham friends, which she
is.
The timing of this rumor was unfortunate as I was not on my computer
yesterday (I was running a temperature of 102.4 due to a bacterial
infection). Needless to say, the only thing I was doing was going to
the doctor.
Thanks to everyone for the kind words and thoughts. I hope that there
is still a long time before my friends and family need be concerned with
my SK.

Hi.
The club in Saskatoon (VE5AA) is looking at a remote digipeater site. The
remote site is about 105 km away. Both the local and remote digipeaters
would be located on the tops of 250 foot buildings which is far above other
building or local terrain. Each digipeater will be running 25 to 35 watts
with ~6dBi gain antennas. (Feedline losses haven't been included yet)
The problem is that there is a range of hills between the two sites. Based
on propogation prediction software, this obstuction means our best signal
level would be about S4 (I can calculate it in uV or dB).
I'm looking for opions on whether this signal strength would be enough to
provide a reliable link between the two sites.

Just tried to take a look at my trucks position at
http://www.findu.com/cgi-bin/find.cgi?kd5xb-10&radar=*** and got a white
box with "Unable to create map..." in it. Hope this isn't a bad omen or
something...

105 KM is what? 65 Miles.
That's a pretty long haul. I have enough trouble being heard by the
Beresford Digipeater, which is about 28 miles south of me, here in the
relatively flat and unobstructed state of South Dakota.
Speaking of which I better look out in the backyard and see if we still
have a tower...after last night's twister-fest. :) Manchester, SD
was "scrubbed" from the map yesterday - No deaths reported, thank goodness.

It works for me no problem (that is my callsign) but I see what you say
about your link.

I take that back... It just happened to me when I hit reload again but I
clicked on it a 2nd time and it worked. Maybe they are just working on
the system.

It may not be 'their system'. I have a number of other services that in
the last week or so seem to be dropping packets in the chain something
fierce. One of the symptoms is partial loads of pages, or just plain
'missed clicks'.
Working with one of the sites, all appears well at their end. We haven't
traced it through yet, but it appears that somewhere in the chain, there's
a link that's dropping stuff. And dropping excessive amounts of packets.
