Are you promoting AMSAT activities to area mobiles?
Now that there are 3 Kenwood and 4 Yaesu radios with front-panel
APRS displays, and TT4, OT2, HAMHUD and other add-on displays to
older radios, the Ham community is starting to finally see what
APRS was always about - the desimination of
local/relevant/real-time ham radio activities and information to
other operators. It was not about vehicle tracking!
It is an information sharing channel so that everyone can see
everytrhing happening on ham radio in the area. This means INFO
that is pushed to the front panel of APRS radios and operators:
* Locally reecommended Travelers Repeater
* Local Echolink or IRLP Freq, tone and codes
* Local NETS or Meetings planned or in progress
* Location of next HAMFEST (drive right to it)
* Azimuth, elevation, freq and doppler of any AMSATS in view
* Bulletins and Announcements, Weather alerts.
* and many more.
So, if you are doing *anything* AMSAT related and you want
people within your area to see your activity, then you should be
posting an APRS AMSAT object so that everyone will see it. For
example, HAMFEST Objects are posted up to 2 weeks in advance and
so everytime someone gets in his car, or drives through the
area, he will be alerted to this coming hamfest on the front
panel of his radio.
We should be doing this for AMSAT activities too. Even if you
are just doing a demo in a parking lot. Send it out on APRS and
everyone in the county will see what-when-where and why. I have
prepared a web page to show you how to post these objects:
www.aprs.org/hamfest.html
But it is like any dead band. If no one is posting these
objects, then there is nothing to see. That's why we call it
"amateur radio operating", not "sitting" or "listening". If you
don't post these objects, who will?
This is just part of the larger APRS Information Initiative to
push relevant info TO visitors and mobile operators. See
www.aprs.org/localinfo.html

Hi Rocky,
The ARISSat-1 uses a linear transponder that is significantly more
efficient.
The COMM RX, CMD RX and the half watt output linear COMM TX only draws
420 mA at 8 VDC. The entire design can also be configured to run
directly from 3.6 Vdc, which is conveniently the voltage of a Lithium
Ion cell. In the absence of the battery cell (if troubles arise with the
battery), it could also run directly from a pair of series connected
solar cells (but not at the 0.5 watt output level), which typically run
about 4.6 V. Additionally, the design can also fit into the CubeSat
physical configuration.
So William's design isn't there yet - at least the last I heard.
So you ask, why don't we use it in FOX?
Well 420 mA is still too to close to the current output capability for
the typical CubeSat solar cell setup. Remember, you also need current to
run the IHU, the MPPT etc. But we're always working on improving the
efficient in the linear mode - so who knows.
The AMSAT-UK FUNCube folks will be designing a linear U/V transponder
for their CubeSat, so we'll be watching their results closely.
Regards...Bill - N6GHz

Vince,
When I saw the ARISSat-1 prototype operating at the Dayton Hamvention, the
linear transponder, the CW beacon, and the FM telemetry/announcements/SSTV
all operated *simultaneously*.
Note that ARISSat-1 does not have an FM repeater mode. The FM transmitter
is used alternately for telemetry, voice announcements, and slow-scan TV
pictures.
Gould's presentation on ARISSat-1 from the AMSAT Forum at Dayton is on the
AMSAT website. It includes slides with diagrams of the uplink and downlink
frequency plan, and a waterfall display of the transmitter output. The
waterfall clearly shows the linear transponder, CW beacon, and the FM channel.
My expectation is that the linear transponder will be operational as long as
either the battery or the solar cells are providing power.
73, Steve N9IP

I can't for the life of me understand the point in people using terms
that tend to divide AMSAT into different groups or warring factions.
The last thing in the world this organization needs right now is to be
divided about anything.
I don't think the people you derisively refer to as " FM'ers" would be
at all upset if some type of linear transponder flew on any new bird. I
think when you get right down to it, everybody wants the same thing
which is a variety of sats with different mode capabilities that will
interest and accommodate all sat operators. I think all of us want an
HEO if at all possible. The thing is though some of us seem to be more
in tune with the realities of the modern world and realize that the
launches are not financially feasible. We don't live in some type of
fantasy land where we think launch opportunities grow on trees. We make
due with what we have and try to enjoy ourselves instead of pining away
for the "good old days". We try to support the BOD in whatever endeavor
or direction that they feel is best for the organization right now. Do
you honestly think they are lying to you when they tell you that
financially feasible HEO launches are not available at present? Or that
it's not possible to include a linear transponder in a cubesat which
appears to be the only viable option we have for launches right now?
That must be it! It must be some kind of conspiracy that has been
hatched by those dastardly scourge of the earth "FM'ers". :-)
Right now I'm an "FMer" because that's all the capability I have right
at present. I could have bought another TS-2000X like I used to have and
be on the existing linear birds but I blew my wad on a Flex 5000 because
frankly, I feel it is a far superior radio to anything else on the
market. It will take me quite sometime to save the money for the
upcoming V/U module that will give me linear transponder access again,
maybe even a couple of years, but for now I'm I try to be happy with
the capability I do have which is a portable FM sat setup.
I don't think that myself or anyone else should be labeled and looked
down upon for simply trying to enjoy ourselves on the birds in the best
way we can.

Michael, W4HIJ

I don't feel a bit sorry for those who gripe on this BB about there not
being enough HEO birds, too many FM birds (operators), not enough linear
transponders, or the like. Yesterday, I encountered a nice FO-29 pass
with maxEL about 60 degrees here at my QTH. I heard no one, yet I could
hear my CW/SSB downlink signal from the bird loud and clear. For awhile
the footprint covered the entire 48 state region. I thus called CQ for
nearly 15 minutes, but no one (that's zero, na-da) came back to my calls.
Then later there was a good VO-52 pass and I did manage to work N6PAA,
very good clear SSB signals both ways. But during the 10-15 minutes of
that pass, I heard no one else in a QSO or calling CQ etc.
I think before we start making complaints about the current state of
affairs, we seriously consider making use of those resources we do have
at present. And then make a financial donation to the various AMSAT's
and teams working to make future birds possible. We all want another
HEO with lots of modes/bands, but complaining will not make one
magically appear.

While we are collecting cents!
AO-40 a HEO was available for up to 12 hours each pass. Doppler and antenna
pointing happened slowly for most of the pass. I had one antenna on a step
ladder the other on a tripod. A slight adjustment every half hour was all
that was needed. I worked 10 foreign countries and all across the US. I
could set up and work at my leisure as many Stations as I wanted to. 1/2 to
one hour QSO's were common. It was not rush and set up your gear have a 5
minute hair raising QSO experience, controlling Doppler on two frequencies
using one knob, or throwing out a perfectly good operating radio because the
computer control doesn't work.

Bob,
This, from the web site, looks like your problem. You can get the patch or
latest version there.

5. Patches
a. SatPC32/Wisat32 patch
The ZIP file that can be downloaded with the link below contains revised
SatPC32.Exe and Wisat32.Exe files (English demo version for North American
users).
The files that come with the 12.8a setup file cause a math error (message:
"Ungueltige Gleitkommaoperation" = "Invalid floating point operation") in
the following case:
a. In menu "Optons" the SGP8SDP8 model has been chosen (the SGP4SDP4 model
works flawlessly).
b. An element in the Keplerian data set ("bstar drag term", data line #1,
col. 54 - 60) contains the value 0. Presently (Dec. 2009) that is the case
with data sets for HO-68.
Selecting the SGP4SDP4 model fixes the problem also. The results of both
models are of equal precision.
Further, the revised SatPC32.Exe file fixes the following error:
When the program's "Priority" function automatically switchs to a satellite
it will set a possible converter or transverter offset to 0. So, the radio
will not be tuned to the required downlink or uplink frequency.

Ditto on Larry's comments. Coming off my KH6 Dxpedition in March/April, I
can concur there are not enough users on the current linear satellites. Out
of the 50 passes that I worked, mostly on SSB. I only made 50 contacts! On
about 3/4 of the passes, I had the satellite all to myself! This included
FO29, VO52, AO7 and HO68!
One day, I had one pass that was deep into CONUS on HO68. I had previously
announced my intent on the AMSAT BB to be on the pass. During the entire
pass over CONUS I did not work one single station. I eventually heard one of
the KH6 stations on Oahu pop-up to say hi as he felt bad that I could not
work a single station during the entire pass. Go figure!
The same happened on several passes over Japan. I was asked to make an
effort to work JA's as KH6 is difficult and rare for them. Again I announced
the passes I would be on. I tried eight different passes often calling and
calling. I eventually made contact with two stations one stormy evening. I
was later told the passes I was on were usually at 4PM in the afternoon when
most stations are at work.
Let's use the resources we have. We have four great LEO's: FO29, VO52 and
HO68; and AO7 when she behaves. Let's get more activity going on these
satellites. I know there are many operators with single SSB Multimode rigs.
Half duplex does work with SatPC, see my DXpedition article on the Caymans
last year. I have already had several email on how to do this from
interested operators. We should encourage newer operators to take the plunge
even with just one radio, with some assistance from the AMSAT community to
get it right. Let's get on the air!
My 2 cents.
73, Adrian AA5UK

I don't feel a bit sorry for those who gripe on this BB about there not
being enough HEO birds, too many FM birds (operators), not enough linear
transponders, or the like. Yesterday, I encountered a nice FO-29 pass with
maxEL about 60 degrees here at my QTH. I heard no one, yet I could hear my
CW/SSB downlink signal from the bird loud and clear. For awhile the
footprint covered the entire 48 state region. I thus called CQ for nearly
15 minutes, but no one (that's zero, na-da) came back to my calls.
Then later there was a good VO-52 pass and I did manage to work N6PAA, very
good clear SSB signals both ways. But during the 10-15 minutes of that
pass, I heard no one else in a QSO or calling CQ etc.
I think before we start making complaints about the current state of
affairs, we seriously consider making use of those resources we do have at
present. And then make a financial donation to the various AMSAT's and
teams working to make future birds possible. We all want another HEO with
lots of modes/bands, but complaining will not make one magically appear.
