Patrick,
Thank you for your efforts to promote AMSAT and satellite operations.
I appreciate them very much, and I know many others do, too.

Subject: [amsat-bb] QSL cards mailed today
Hi!
After printing more QSL cards on Sunday and writing out almost 200
cards along with envelopes last night, I dropped a large batch of
envelopes at the post office this morning.? These cards cover my
activity from the east coast around the recently-concluded AMSAT
Symposium (Washington DC/FM18, BWI Airport MD/FM19, Bear DE/FM29),
as well as Saturday's activity - the Tucson AZ hamfest (DM42) in
the morning, and at or just east of the Arizona/New Mexico state
line (DM52) in the afternoon/early evening.?
Thanks to all who worked WD9EWK from these locations over the past
couple of weeks.? I enjoy getting on the air from almost anywhere
I go, and the QSLing after the trip is an important part of that.?
73!

Hi Patrick!
THANK YOU! THANK YOU! THANK YOU! Your GridXpeditions are appreciated by
one and all. I am sure the demonstrations at the hamfests, and other
events, capture the attention of possible future satellite ops, young and
old alike. It never ceases to amaze me how much fun one can have, along
with the challange, of trying to work for WAS Satellite or VUCC Satellite
while tracking and attempting to hit, with RF, a roughly 1 cubic foot object
moving nearly 17,000 MPH.
73,
Jeff WB3JFS

Hi Bob,
I think the following site does pretty much what you are asking
http://www.heavens-above.com/
If you register there and input your location one of the options is to
display a list of Amateur Satellites for a 24 hour period. It does list all
passes and not just the best. You can use the next button to select the
following days. The site developer Chris Peat is very helpful, I am sure he
could tweak the page to better suite our needs

Subject: RE: [amsat-bb] Re: volunteering (Mobile Satellite PAPER Predictor)
Actually, There is another similar WEB page project
That does the same thing for ALL mobile operators,
Not just those with APRS displays. It is simpler
And only has a single TEXT output:
Please see the idea on this web page:
http://www.aprs.org/MobileLEOtracking.html
PROJECT OBJECTIVE: Develop a web page that any amateur radio
operator can go to that will print out this very simple PAPER
tracking device. It is just a piece of paper with 5 columns for
each of 5 days, and on each of those five days, the TIME of the
best overhead pass for that users local area (morning and
evening). For ECHO (AO51) this simple piece of paper with 10
times on it can be used for SHOWING the pass times of ALL
morning and evening passes for the next 2 or 3 months!
You don't need no stinkin computer to always know when AO51 is
overhead while you are mobile! Just look at the TIME on the
paper for today's date. (ECHO's pass times repeat every 5
days)... Each other satellite has similar REPEATABILITY. Just
pring one of these slips of papwer for your favorite satellite,
and you will never need to do a prediciton again, yet, will
always hve what you need in the car to predict each day's pass
times.

I would suggerst the you contribute far more than the majority of members.
Many of your professional projects have amateur spin-offs and involvement.

Hi David
Sadly no I don't have any 2m design experience, my design experience is
mostly high voltage switch mode PSU for powering Traveling Wave Tubes, and
the microcontroller based management systems for controlling high power
travelling wave tubes + PSUs. Mostly I have done the microcontroller aspect
of that. Over recent years I have been mainly involved in I.T. admin in
schools

Actually, that is really quite different. That does what all
tracking programs historically do... That is, they produce
VOLUMINOUS precise predictions for every pass for every day. TO
carry such an output in your car for a month would be about 30
sheets of paper.
The small piece of paper that my proposal outputs is a single
piece of paper with about 10 numbers on it, no bigger than about
2" by 3" suitable for taping to your dashboard above your radio.
Yet that tiny square of paper can be used to estimate ALL pass
times for ECHO (AO51) for one or more months, before needing to
be replaced.
Thanks

I note that Kenwood is releasing a new APRS/GPS handheld soon to replace the
D7.Does anyone know if it will run full duplex or have the specs?

Bob, I am one in total agreement with you on this one. We can all get
this information on the iPhone, (and maybe other smart phones), our
netbooks, laptops and our desktops. But while driving down the road at
60 or so miles per hour and seeing a current FM sat come up on my
D-710/700 in the footprint via RF with an elevation and azimuth that is
currently workable is the ultimate solution in my mind.
I am one of those 1,000's of operators worldwide you referenced
transmitting current satellite positions on a local network, in my case
via digi_ned on our local UHF alt-net running on 440.800Mhz at 9.6kbaud
within a portion of NWAPRS coverage area (Puget Sound). Within this
coverage area it works great, its so nice to glance down at the display
and see AO-51 (or others) to the west and over 30 degrees, I hit PM3 and
listen to the pass. Sometimes, I even make a contact or two.
You have defined the problem very well, when mobile and outside the
footprint of a repeater providing this information ..... well what do
you do, your only option is to revert back to the internet. Not the
ideal solution in my mind. I like RF, thats why I am an amateur radio
operator. I am not smart enough to provide a solution. But, it seems to
me, that if local igates do not gate these types of packets back to RF
in their operational area then the only solution is for us 1,000's of
digi operators worldwide to provide this information in each of our
operating areas.
I always enjoy reading your posts Bob ...... Thanks for all you do

Hi all,
How about a compromise? There's an old DOS program that I used many years
ago that printed out a chart, one line per satellite per pass, sorted by
time. One page would hold several days worth, depending on how many
satellites you wanted to track. Not as compact as the chart I think Bob has
in mind, but just enough detail to work out when to start waving the
aluminum around. I used to run it for the month and save the output on my
palmtop, for handy reference.
The program was PCTSCAN.EXE, part of the PCTrack package (PCT214). It has
some Y2K issues, but I've got a patch program that I think still works to
fix the database. I've got the program and such posted on my web site, if
you're interested. http://home.wavecable.com/~ko6th, about 1/3 of the way
down the screen (31 March, 2002).
The output looks like this:
