Message-ID: <WC20111024143340.050C65@xxxxxx.xx.xx>
Content-Type: text/plain; charset="us-ascii"
Hello all,
I have been active almost by 2 months on AO-51 from Havana in EL83sc. Due
to my poor reception omni antenna I am working only the AO-51 in the
afternoon passes only with a elevation greater than 60 degrees over
Havana, also at the time it pass I usually am at work so only saturdays
and sundays I may be active. So if any of you need to confirm the grid
EL83 don't worry, just be patient, if you see a weekend pass with high
elevation angle over Havana I may be there. QSL card is 100% sure with out
SASE or IRC required only after you send a QSO confirmation e-mail to me
with your callsign, and date/time of QSO, also I would like to recieve
your QSL card too. Not sure if I will be able to work AO-27 or SO-50 as
those birds have less power out. But if I heard them some day I will try TX!!!
That's all, 73 and Hope contact your station soon.
Regards,
Raydel, CM2ESP
Havana, EL83sc

Amateur radio is a fun hobby, don't pretend it is a police ancillary
service, that was never the intent. If you happen to be with

No Bob I'm in no way trying to hold anyone back just that like I said it seems
to be that same people pass after pass after pass.
How about giving someone else some air time? is that to much to ask?

The IARU is a consultative body, a place for the amateur societies to
coordinate international activities where possible , not an international
treaty organization with the ability to bind member country
telecommunications law. It has no real power. We use it to do amateur
satellite service frequency coordination and for all countries, groups, etc.
that actually follow this procedure, it is helpful. Many do not.
The ITU maybe, but not the IARU, and the ITU hosts the World Adminstrative
Radio Conference where treaties and the thousands of exceptions to any
agreement are added and where any real power exists. WARC==important,
IARU==sometimes useful. Those would be the ones that are like a George W.
Bush "signing note". They sign but then say they won't obey.

Hi Roger,
I have updated http://www.pe0sat.vgnet.nl/satellite/sat-history/prospero/
with my latest images and recordings. It is possible to get the complete
audio file. Send me a direct email and we can arrange something.
I had read that there is a 148.000 MHz transmitter on board prospero, and
I listend to that frquentie during the pass from 15:55 UTC. Maybe it is
interesting what is happening on that transmitter.
How do things go on your site regarding PROSPERO? any news?

John,

> Just way to many "kids, lids and space cadets "
Near useless? The FM satellites worked very well for many to make
QSOs on the passes I worked on Saturday. Yes, rapid-fire QSOs are
the order of the day, but you'll hear the same sort of rapid-fire QSOs
next weekend in the CQ WW SSB contest. And..... wait for it... that
contest doesn't use the satellites. It's on HF! Many thousands spend
that weekend making lots of QSOs, and giving out the same information
for each and every QSO. Hams will travel to many different parts of
the world, just to be able to say "59 (CQ zone number)" for up to 48
hours on the radio.
As for the W2OY reference... let's see... At 43, I'm not a kid. Some
in a local radio club will call me a "kid", since I am a bit younger than
the median age of the club members. I'm not a lid, so I guess I must
be a space cadet. Do I get a certificate for that? Thanks for clearing
that up for me, John. I needed that dose of name-calling on a
Monday morning. :-\
> Standing in their back yard on a FM HT.
Oh, no! Someone is using an FM HT in their back yard to work a
satellite? Heavens, no! Report them to.... ???
I've been doing satellite demonstrations and presentations out
here for almost 5 years. Even after being at some of the same
hamfests for each of those years, there are still people who do
not understand that satellite operating does not require a huge
station and lots of $$$ to get started. Yes, you can end up
spending a lot of money. It's the same for those on HF, who
want to go from a 100W transceiver/dipole station to something
with Yagis, a tower, a transceiver with more bells and whistles,
maybe an amplifier...
> Pass after pass it seems to always to be the same people.
I wasn't on the satellites in the HEO days. It seems like that you
would have also heard many of the same people on AO-40, day
in and day out. Other than possibly having longer conversations
on HEO satellites than you would on LEO satellites, it may have
been similar to what you heard on the FM birds. This is a bad
thing because..... ???
> Sure do (still) miss AO-40....
I miss that, and the other HEO satellites. But it's 2011, not 2001,
and AO-40 isn't here. It might come back like AO-7 did, but it might
be like most ham satellites - once it goes quiet, it stays quiet.
Rather than listening to the silence from AO-40, I'll keep on using
the satellites that are operational. I'll also continue to make friends
as I log more QSOs, keep learning more about this corner of our
hobby, and - you've seen this in many of my -BB posts over the
past few years - having fun!
I'm looking forward to the presentations about the Fox project at the
upcoming AMSAT Symposium. I'll keep going out to hamfests with an
AMSAT table, because it is fun to meet people and talk about this
corner of our hobby. I'll look forward to other projects like FUNcube
and KiwiSat, hoping to have more satellites in whatever orbit to work.
Maybe that new Polish satellite I just read about with the FM/SSB
transponder will be just as much fun as AO-16 was a couple of years
ago. And, yes, I would love to see P3E launched and operational.
I would be happy to adapt my portable all-mode station to work that,
along with the other satellites.

Hi Andras,HA6NN
You are one of the only person that agree with me because if you like to
talk for more than 5 seconds giving only your call and locator into a lot
of QRM on a FM satellites actually for a decent QSO there are no usable
satellites except AO-7 and VO-52 and this is why I pull for a HEO satellite
like P3-E but every time I did it I receive a lot of insult in AMSAT-BB
I spent a lot of money on satellites according to the long term plans of
IARU, ARRL and AMSAT which promised to provide us with HEO satellites
to communicate worldwide much better than in HF.
After AO40 died about then years ago my antennas for the S band and K
band are becaming rusty over the roof waiting for the future but....what
future if we cannot experiment on worldwide satellite communications
using from VHF to the microwave bands ?
Yes you are right writing:"I had better to buy a well equipped HF
transceiver instead! "

Hi, Bob!!
Ultimate authority rests with Member states (note the capital "M"), which
have made an agreement (treaty) with each other. The treaty basis comes
from the notion that if the various parties can't play well together,
everyone will be harmed.
See: CONSTITUTION OF THE INTERNATIONAL TELECOMMUNICATION UNION
Preamble
1 While fully recognizing the sovereign right of each State to regulate
its telecommunication and having regard to the growing importance of
telecommunication for the preservation of peace and the economic and social
development of all States ? .
ITU, itself, serves only the functions agreed to by ITU Plenipotentiary
Conferences and added to the International Telecommunication Convention, the
treaty, and the radio regulations, which are annexed to the treaty and have
the same status as the basic treaty.
The world expects more of amateurs than every other radiocommunication
service, since all others involve specific notification and coordination
requirements.
Amateurs have long been expected to manage and coordinate their own use of
frequencies. "Listen before transmitting" works in many cases. Satellites
need more.
This is why IARU provides satellite frequency coordination recommendations.
Yes, these are only recommendations and participation is not required,
unless required by a licensing administration. Anyone truly interested in
the success of a project will participate in the process - to keep the
probability of success high and the probability of causing problems low.
Make sense?
I hope this helps.
73, art?..

I have at times patiently awaited the pass of the ISS to work a different
packet station only to miss the opportunity by the repeater being busy the
entire pass by trying to deliver BBS mailbox messages to someone and that
station never retrieves his mail . It's just one of those things We endure .
I have been calling 2 HF traffic nets for several years and have attempted
to pass traffic to someone in the same town as the message is to be passed
to , only to have that station deny taking that traffic . Why would anyone
check in to a" traffic net "and then refuse to handle local traffic ?
Sometimes I just don't get it , but We hang in there regardless . 73's

You will find the same situation on VHF/UHF FM and on VHF/UHF weak signal
and the same complaints.
I heard the same complaints with regard to the analog sats back in the days
of AO-13 -- same guys always on, hogging the pass band, running too much
power, etc.
Solution - Try something new for a few weeks or months - HF, PSK31, FM
simplex, 6 meter FM, 6 M ssb, 40 meter cw, etc.
When you get bored with that, then try the sats again.

Hi Bernhard!

Other than what KA3HSW suggested, the closest thing to a handheld
10m antenna may be a whip of some sort. Or possibly go with some
sort of wire antenna. Still not truly handheld, but a small antenna for
10m will make hearing the downlink a tough exercise.
During the past summer, I took out my Buddipole dipole and its 8-foot
mast and tripod to work with AO-7 in mode A. I settled on an L
configuration, where the horizontal part of the antenna pointed toward
the satellite. I would move the antenna every minute or so, and held
my Elk antenna toward the satellite for the 2m uplink. That worked
OK, but not great. I could easily hear my 5W CW signals from an
FT-817ND through the mode A transponder. It was much harder
when I went to SSB at the same power level. I made one mode A
SSB QSO with W7JPI, and that was hard work. Now that I have a
back yard to work from, coupled with the end of the summer heat
here in Arizona, I may revisit that over the next few months.
Good luck, and 73!
