I have a pair of M2 Eggbeaters, the EB-144 and the EB-432, both with radial
kits. I will only sell them as a set. They work beautifully with the LEO
satellites. M2 makes a fantastic product and the cost new is $519 + S/H.
I am asking $325 firm which includes S/H to the CONUS ONLY.

To Shuttle rebroadcasters:
Many people do not monitor your Shuttle Retransmission
frequencey all the time, and so, may not remember that the
Shuttle is in orbit. Therefore, a TNC should be connected to
the Retransmitter that activates an APRS beacon on the local
APRS channel whenever it is keyed. This APRS beacon will alert
all mobiles on the front panel of their APRS radios in range
that the retransmission is in progress.
We need to get this info out to all volunteer rebroadcasters...
This web page shows how to use just an old TNC and no special
software to format the beacon so that it shows all the relevant
information right there on the front panel of the mobile APRS
radios:
http://www.aprs.org/On-Air-beacons.html
This technique also applies to all re-broadcasters of the
Newsline, RAIN report, ARRL Audio file, and any other general
info nets that need to be heard by all radio amateurs.
APRS is your universal real-time ham radio information channel.
If you have info to share, beacon it on APRS live. Monitor APRS
and see what is happening in your area.

I guess your idea must have some merit but I've never seen/known anybody to

Yes it was great to see them get into orbit with a very nominal mission.
Watching the live video coming up from Ascension Is. of the second burn was
very cool.
I have already been talking with SpaceX regarding AMSAT opportunities.
Interestingly they don't have test flights planned for the F9. They've got
paying customers manifested right on from flight 1. Also, since they are
focused on their COTS contract for delivering supplies to ISS, many of their
initial F9 flights will be to LEO. They are working on GTO mission though.
When I last spoke with SpaceX they were not very interested in dealing with
secondaries. Their business model and costs are based around launching a
single payload. However, they don't care if that "single payload" is
actually a stack of satellites as long as someone else does the integration
and delivers them an integrated payload stack. With that I've also been
talking with the company who brokered the multi-manifest mission for F1
flight 3, since they are smallsat friendly and already have a relationship
with SpaceX.

PS My day job at the Eastern Range includes working both Atlas V and SpaceX

Interesting... but that is what APRS was designed to do. To be
an information exchange, distribution and display system for
mobiles.
Unfortunately, I fear you have been missled into the incorrect
view of APRS as a "vehicle tracking system" which has nothing to
do with what it was designed for. APRS was around since the
1980's and GPS was only folded in in the 90's when they became
cheap enough. But tracking GPS modiles is only a small side
benefit of having full tactical situational awareness, Local
Frequency recommendations,
Satellite's-in-view/frequencys/doppler, global messaging by
callsign and global email text messaging from the front panel of
your APRS radio.
Its because of the proliferation of tracking devices that has
misslead most casual observers into only seeing maps of
vehicles. If that's all they see, they are not seeing the local
info displays that the APRS radios present to the mobile
operator.
Kenwood has been abismal in their full page ads, because they
never show any of the local info displays! They only show a
dual band radio, mention APRS and GPS in the text, and leave the
missinterpretation up to the 98% of readers who have never
experienced APRS...
Another local NET that should be advertised to mobiles is
whenever an AMSAT net is in progress. Just send out the beacon
and do not be surprised if your fishing brings in some mobiles
from other frequenceis checking into the net...
Please see the web page on these misconceptions:

Thanks Bob.
You're correct, I have only ever used it or seen it used for vehicle tracking
and whilst I was vaguely aware that it could send messages,
believed that the messages were too short to be of any use.
So, on to equipment.
I've used an old handheld radio, tinytrack, laptop and GPS for vehicle
tracking.
I guess for base station/home use I can use any 2M FM radio, 1200BD TNC and
PC with some, unknown to me software. Please advise on the software.
I've got an old spare GPS for mobile use but what current reasonably priced
mobile radio (preferably dual band) would you suggest if I'm to buy
a new one. I guess the ability to plug a laptop into the radio as well as the
GPS would be a bonus for messaging.

There are many ways:
1) The KWD D7 or Yaesu VX8R HT's have built in APRS and are dual
band and great for handheld satellite communications.
2) The D700 and new D710 mobiles have larger displays and are
50W dual bands.
3) Or you can add an APRS display to any radio using either the
HAMHUD or the RC-D710 Display unit (this is simply the D710 APRS
control head (sold separately) so that it can be connected to
any radio (all APRS functions and TNC are built into the head.
See www.aprs.org/D710-HT.html which shows the display head
connected to an old $88 HT.
4) Or you can always connect any old radio/tnc/PC combo, or
these days, many programs can use sound card TNC's so no
hardware other than a radio and PC are needed.
Once the kenwood radio integrated everything back in 1998, I
have not used a mobile laptop since, but can still see all
surrounding APRS activity...
And information.
Good luck!

Ah, I found the old web page on the APRSdata engine that puts
out the local satellites-in-view to all mobile APRS radios in
the area showing the satellite in view, updated every minute on
the front panel of the radio:
1) Direction and distance to the bird
2) Downlink and uplink frequency
3) Current doppler for your location
4) Direction of movement in the sky
And if you have the D700 voice unit, the radio will speak
OSCAR-X HIGH, or OSCAR-X LOW as it moves across the sky... So
you don't even have to look at the display.
See the web page: http://www.ew.usna.edu/~bruninga/APRSdata.html
Only one person per region needs to run this, and it updates all
mobiles for the surrounding hundred miles. You never have to do
satellite tracking again, yet you will be alerted to any
satellite in view while you are mobile.
This program is over 10 years old, and someone should update
this for Windows... And with a slight change in format, the new
D710 will automatically tune it. I cannot make the changes,
since I lost the source code years ago.

with 'standard' ham SW, eg NOVA

Hi Folks,
We have recently installed an M2 az/el system, with two of the controllers
mentioned above. The controllers are separate units, linked with a single
ribbon cable.
The units work OK when given raw commands using hyperterm, but only the
last addressed unit seems to send back to hyperterm its info as it moves. Ie
send a command to change Az, followed immeadiately by a command to change
El, and only the El position appears in hyper term as its changing.
Command the az/el from the front panel of the units works OK, also.
When we try using 'standard' ham satellite software, eg Nova, nothing
seems to happen. The rotors just dont budge.
If anyone has any experience in solving this problem, I'd love to hear
from them

I am moderated on bod (I thought anyone could send to bod?) so this may not
get to them.
Please make sure they all see this.
Peter Guelzow is in contact with SpaceX and he is going in at the top. It
never works in a timely fashion to be "talking to SpaceX" or Intelsat or
anyone else when you are talking to someone who has no ability at all to
talk the entity into accepting something odd, different, and outside the
normal business model.
We have always done business, right back to the beginning of AMSAT, by
looking for low friends in high places. It is the only way we will succeed.
I say we should continue to make contacts but we need to get real about the
approach.

Yes it was great to see them get into orbit with a very nominal mission.
Watching the live video coming up from Ascension Is. of the second burn was
very cool.
I have already been talking with SpaceX regarding AMSAT opportunities.
Interestingly they don't have test flights planned for the F9. They've got
paying customers manifested right on from flight 1. Also, since they are
focused on their COTS contract for delivering supplies to ISS, many of their
initial F9 flights will be to LEO. They are working on GTO mission though.
When I last spoke with SpaceX they were not very interested in dealing with
secondaries. Their business model and costs are based around launching a
single payload. However, they don't care if that "single payload" is
actually a stack of satellites as long as someone else does the integration
and delivers them an integrated payload stack. With that I've also been
talking with the company who brokered the multi-manifest mission for F1
flight 3, since they are smallsat friendly and already have a relationship
with SpaceX.

PS My day job at the Eastern Range includes working both Atlas V and SpaceX
launches.
