Speaking of which, can any of the available amateur software packages
handle a moving ground station? I'd like to be able to automate the
antenna tracking on a boat.

Hi Doug,
You might check out Lynn KJ4ERJ's APRSISCE/32 package. The development
version can track satellites, and as an APRS App it's dynamically
self-position aware by default. I don't think it currently outputs to
anything that can drive an antenna or Doppler tracking, but the program is
under active development and it's rumored that he can be bribed to make
enhancements with suitable quantities of Mountain Dew. Even so, you will
need to be creative in the lash-up.

Doug,
FODTRACK does have a GPS input for the location.
http://ludens.cl/Electron/fodtrack/fodtrack.html
Note that it is a VERY old, DOS program, but according to the web page, with
some effort will work with Vista and presumably WIN7. FWIW

Doug and Alan,
The LVB Tracker II will do the same as well. From what I read, to convert a
LVB tracker 1 to a LVB tracker II, it requires
a Eprom change and new software load.

Odd... I am surprised at the number of folks who need NH... there are
actually a
large number of hams in southern NH.
And I work less than 15 minutes from the MA/NH border. HRO Salem, NH is 20
(and no one there will
question what I am doing in the parking lot)
There is a large regional hamfest in Deerfield, NH (NEARFEST, formally
known as Hosstraders) twice a year ---spring and fall; an excellent
opportunity for portable/handheld operation.
And this past summer I did spend a few weekends up in ME (Old Orchard
Beach).
If you really do need NH or ME (or MA, for that matter), please send an
email to <my call> at hotmail dot com.
Put the state abbreviations you need (only) in the subject line
e.g. ME
or
ME NH
I'll build a quick dis list and email when I am going to be on from those
locations.
I'd rather not "open post" because I think it swamps the birds. I can do
AO-27 now, and
I'm figuring out a good way to program the FT-530 for SO-50.

Doug,
I worked for Sperry and other maritime electronics companies. Using a
satellite tracking antenna on a boat needs to have a North input to have
a relative tracking of an object-You can also have a heads up input.
There are mobile antennas for the DISH network that can meet your needs,
however, you must adapt the "North" input to the trackers. I'm sure you
can modify the antenna to make it receive on the proper frequency you
desire. They are not cheap, however, if you shop on e-bay, you may find
one to fit your needs. Interface to say- PCSAT32 - may be unique.
Good luck.
73,
Dee, NB2F

Speaking of which, can any of the available amateur software packages

The Balloon has APRS on it, so it is telling us where it is. We have GPS,
so we know where we are and our heading, a PIC processor takes those two
inputs, does the 3D math and points the AZ/EL mount. Again, the dish will
be an open-wire grid with nearly 1" spacing and have little drag.
Will have to power the Yaesu mount from a 115v AC inverter because they are
AC motors..

Yes, that is correct APRS message format for an Email

That will work just about anywhere in the western hemisphere on 144.39 or in
Europe on 144.800.

> My last terrestrial test did not seem to work via wide2-1.
Any APRS packet you send can be verified that it was pickedup via the global
APRS system by simply going to http://APRS.FI and entering the callsign. If
that station has never sent a position report, then APRS.FI will say "no
position known" but that does not mean that it did not capture the message
packet. To see other packets fromany station, click on Other-views/Raw
packets and then enter the callsign on that page and you should see your
packet within seconds (if it was heard)..
Whether it gets delivered by actual email is a separate issue. I just tried
it and got the email within less than a minute.
If you have an APRS radio all the formatting is done for you. Just send the
APRS message to EMAIL and the first word of the message must be an Email
address.
Send it on 144.39 VIA WIDE2-2
Send it on 145.825 via ARISS
Good luck

Any chance he might be willing to assist in the Ham Radio Appalachian Trail
Survey being planned for this spring? Volunteer ham hikers with APRS radios
will be hiking and need volunteer logistics support at road crossings. See

No reason they can't do some sat contacts from the trail either (though some
hikers will be upset if you don't use earphones to remain low profile...).

In an effort to help increase interest in satellites, we have
created a new award for working five (5) different hams in the
EM55 grid.
You do not have to be in your home grid to count the stations
worked. There are several satellite ready hams in EM55. Here is
the current list that we know of:
WA4NVM, WA4HFN, WB4LHD, WA4OVO, KI4OTG, KD4NOQ, KJ4BIX, AJ4KF, W5KUB, N4MGT,
AA4HV and K4FEG
Send your log to WA4NVM or WA4HFN for checking, along with your
current mailing address. The award is free and should any
donations be sent, they will be forwarded to AMSAT along with
your call and name.
This award will be effective 1 June 2011, therefore, all contacts
must be on or after this date.
