Gentlemen,
In case we are rally corresponding about radio amateur calling and QSO
protocol, Dave WB6LLO is quite right writing:
"AO7, is what, 25 years old, none of those problems existed there, and
still don't today..."
Except for the sad fact that some feels it is compulsory to call like "CQ CQ
CQ CQ AO7 satellite this is EE0LL (15 times) is standing by for any possible
satellite call."
During this time of a long call VO52 flyes across Europe and no QSO will be
made at all!
I was planning to write this list asking everyone to KEEP IT SHORT for the
God's sake !!!
I call like "HA6NN CQ"
That's all. As somewhere someone told those who had not been experienced in
RTTY contests, it is a general habit on that mode!
Than there is no rule to tell QSP-partners even your name every time! Beside
this, some tells everything about his equipment, the wx, etc.
THERE IS NO TIME TO DO THAT ON SATELLITES!
Learn the only sensible radioamateur QSO protocol what OH8MBN Mika or UA9CS
Igor uses -not to mention K3SZH and some other regulars on AO7.
> Blame those that encouraged and built AO51...
That was one of the gratest mistake of the history of Amateur Radio.
> Why was it built??
...that is the question.

These comments aren't directed specifically at Andras, but rather to
the general tenor of this thread.
I'm not sure that this list is the best place to discuss egregious
operating habits on the satellites. It's my impression that most of
these are due to newcomers experimenting with setups that have poor
reception or who are very occasional users of the satellites. But this
list isn't, in my experience, well subscribed by those two audiences.
Recently, someone on the list made a longish document regarding
satellite etiquette, and it was picked up by the RSS services. Perhaps
a web or wiki page on these matters would be most effective.
Another thought: people who are failing to receive their own signals
or who are making long CQs to tune their setup (which I suspect is
going on in the situation described above) are, in fact, doing that
which the satellites are meant to support: experimentation with space
communication. If this is so, then they represent the future of our
branch of the hobby, not merely an annoyance. Our advice should be
geared toward improving their experiments and helping them build
satellite communication skills; if their tentative steps disrupt our
regular communication is, to my mind, secondary.
It always concerns me that newcomers reading a thread like this will
be frightened away. It might seem that there are too many ways to be
branded a lid in satellite operations, and if people on email are this
judgemental, it must be brutal on the birds. I'm sure everyone will
agree that this is not the case: a new callsign, however deaf :-), is
greeted with great enthusiasm and everyone tries to support everyone
else with technical advice and a kind word. We want you to succeed and
to learn about the amazing mix of planetary physics and RF that makes
satellite operations so engaging.

Again, for the benefit of the larger audience, it should be noted that
this is of historical interest only. The current AMSAT-NA mission
statement involves the production of HEO satellites while supporting
others in LEO work, FM or not. There may be those of us, like me, who
find AO-51 provided a fine stepping-stone to linear work, but we are
happy to have our membership fees and donations support the HEO
mission. Moreover, the dichotomy between FM and linear LEO is a
somewhat false one. VO-52 has shown that a linear transponder can be
used in FM over part of the world and linear usage over others. Kiwi
sat and others intend to provide both services in their upcoming
birds. I'm grateful to be able to use an FM bird in portable
circumstances, since I don't have a full-duplex SSB radio that I can
carry around in the forest (now that would be a great homebrew project
:-)

Well put Bruce. Being someone that hasn't spent years on the birds and having
originally started my satellite experimentation with SO-50 not all that long
ago it is discouraging to hear the minority of amsat users complaining about
FM birds (why do we have them) or the crowded passes where newcomers may be
having a bit of trouble.
I for one was happy to be able to start by using a handheld radio and antenna
to make contacts on one of the FM birds (SO-50 or AO-51). Having done that
sparked my interest and contributions to AMSAT-NA. I have since started
experimenting since the purchase of a IC-910H with other modes (mostly
listening) and hope to start making contacts that way as well. While I may
have done my due diligence and done a lot of listening before trying to talk,
we can't fault others completely for getting a bit excited or not knowing
"everything" first time out.
Harsh scolding isn't going to drive anyone to use the satellites and it
certainly won't get AMSAT-NA new members or donations. Let's keep our hobby
civil and help guide some of those that may be having trouble. Perhaps
updated how-to's, etc? I support new efforts for a HEO bird with various
modes but also support those decisions that were made for "easy-sats" like AO-
51 to help generate interest and proficiency.

Morning Everyone,
While I agree with Clint on the CQ on a VHF Repeater type system, Just
seems weird if ya hear it at all. same as what always gets me is the
"My Personal Here is " ( insert name ) My Personal, deodorant? or
what? Hello? It's your NAME!
BUT the statement of,,,
"I have never heard that using a Morse Code code on a voice system was
accepted by anyone of importance."
This I'll differ some, I hear and feel no pangs when i hear someone
say QRM is pretty high, or Interference is pretty high.
Or QTH,
QRN
etc.
just feels the same.

OBSERVATIONS FROM NORWAY. February 2008.
Based on SV1BSX's comments about receiving a *THUNDERING* signal from AO-51's
S-band transmitter on a patch antenna 'without' a reflector - I decided to
chuck together a few components to see if somebody as 'thick' as LA2QAA could
manage it.
The attached pic is the ... 'fruits of LA2QAA's labour'.
Starting at the top right we have a silver covered brass plate 2.4Ghz patch
antenna (note the real gold SMA connector, folks) mounted 3mm over a (ditto)
groundplane, via a short length of high quality (fell off the back of a North
Sea Oil industry lorry) coax feeding the input of a 2.4G 70 70cm converter
... the output of which goes to the IC-E91 dual mode handheld and a pair of
'cans' ... (headphones, to you!).
To the right of the IC-E91 is a Nokia N70 mobile phone - (not shown in this
pic because I was using it to take the picture) - with the 'SATme' tracking
software ... which is very !! useful for tracking S-mode signals from LEO
birds with the 'slight' doppler thus received.
The phone also contains a compas as well as GPS software so there's no excuse
for ... 'but I can't find north' ... (not always easy in 3 feet of snow, null
visibility and cloudy conditions) ... and there's *NEVER* a brownie or a girl
guide around when you want one.
S-band signals in those conditions? ... you'd be surprised - we don't all live
in satellite friendly climes you know.
Mak (SV1BSX) is right. A 60cm dish is overkill for AO-51 mode-S ... though of
course, there are! those that think you need a personal
Jodrell Bank to hear anything above 70cm.

I need a little help using pb/pg with GO-32 to upload/download files.
I'm a linux guy, I have a linux machine running ax.25 software, talking
to a TNC in KISS mode hooked up to my radio. Using the ax.25 utility
'listen -a' I can see GO-32 transmit packets when it passes overhead.
I can sort of flail a bit with "pb" and it transmit some packets to
GO-32 and even occasionally see GO-32 send back a packet with my
callsign, so I'm pretty sure that the radio and low level link are at
least sort-of working.
Can someone give me a little guidance about how to use pb/pg to download
a list of files, download a particular file, and upload a file. My aim
is to upload a file, then download the file on a later pass, but I can't
seem to figure it out on my own.
thanks,

Really the S transmitter is very strong
It's easy to receive even with a

But the speed of the Doppler shift is amazing!

I am offering this up for sale here before I put it on eBay.
I have an OLPC to sell. I am not a unix/linux guru and have no idea how
to get the machine to do more than what comes pre-loaded. I connected to
my home network but using it to surf the internet is just not something
I need it for.
The OLPC comes with the ac adapter and an instruction sheet. I will sell
it for the $200 that it cost plus $20 shipping in continental U.S. only
(2-day Fedex).

Mak,
I can assure you the patch *IS* correct.
The photo is taken from the rear, what you are seeing in the photo is the
'rear' of the reflector and the back end of the gold SMA connector.
The radiator - (hidden by the larger reflector, in the photo) - is connected
to the pip of the SMA connector and is mounted 3mm 'above' the reflector.
The radiator is 'cut' for 2401Mhz and is made from silver plated brass sheet
... bas is the reflector.
I think what may have fooled you is ...
1) Not realising you were looking at the rear of the patch.
2) The fact that my reflector is square, not round.
The G3RUH design uses a round reflector, the K3OE uses square.
As far as I can assertain there is no practical difference between the
designs.

I read your post but I am afraid that, your
PATCH is not correct. Sorry if I am wrong, but due to non-clear photo I
can see
on the Left-UP part of photo ONLY
the "drive element" of Patch (the square-piece with cut-corners ) without
the "circular piece" behind of drive-element which acts as
reflector.
As I see also in your photo, the chassis-connector is
mounted on this square piece and not to the
circular reflector.
If that is not my... illusion, that is not a
correct Patch. I send you a clear photo to take a view how is the
complete Patch by viewing that from the front-side.
73, Mak

Subject: [eu-amsat] S-band test
gear.
OBSERVATIONS FROM
NORWAY. February
2008.
Based on SV1BSX's comments about receiving a *THUNDERING* signal
from AO-51's S-band transmitter on a patch antenna 'without' a reflector - I
decided to chuck together a few components to see if somebody as 'thick' as
LA2QAA could manage it.
The attached pic is the ... 'fruits of LA2QAA's
labour'.
Starting at the top right we have a silver covered brass plate
2.4Ghz patch antenna (note the real gold SMA connector, folks) mounted 3mm
over a (ditto) groundplane, via a short length of high quality (fell off the
back of a North Sea Oil industry lorry) coax feeding the input of a 2.4G
70 70cm converter ... the output of which goes to the IC-E91 dual mode
handheld and a pair of 'cans' ... (headphones, to you!).
To the right
of the IC-E91 is a Nokia N70 mobile phone - (not shown in this pic because I
was using it to take the picture) - with the 'SATme' tracking software ....
which is very !! useful for tracking S-mode signals from LEO birds with the
'slight' doppler thus received.
The phone also contains a compas as
well as GPS software so there's no excuse for ... 'but I can't find north'
...
(not always easy in 3 feet of snow, null visibility and cloudy conditions)
...
and there's *NEVER* a brownie or a girl guide around when you want one.
S-band signals in those conditions? ... you'd be surprised - we don't
all live in satellite friendly climes you know.
Mak (SV1BSX) is right.
A 60cm dish is overkill for AO-51 mode-S ... though of course, there are!
those that think you need a personal
Jodrell Bank to hear anything above
70cm.

I am pleased to report that HQ8R will be QRV on the
satellites from Swan Island, grid EK87, from March
15-23. See http://www.hondurasdx.com/
I'll be taking my FT-817 and an Arrow antenna. Time
permitting, I will also try to make a few contacts
before and after the expedition from the Honduran
mainland, EK55, EK65 and EK75. Weather permitting, we
may also try to give out EK76 from the boat on the way
to and from the island.
73, Bill NZ5N
