After years of anticipating the launch of SuitSat-2 and then ARISSat-1 , I
for one have lost My interest in it. I think even with peak performance , it
will take a class "a" ground station to hear any of the formats We're
expecting . Definitely not a school project . I hope it proves Me wrong .

Though I agree with you to some extent (certainly where I live!), the
explosion of smartphones will drive the networks to be able to handle
larger capacities and you will be able to get through faster.
I truly believe RF's real value in an emergency is that anyone can
setup a communication station in minutes because the barrier to entry
is very small, i.e. its the response time which is its greatest asset.

This is kind of a goofy discussion...people like what people like; I drive
to the airport every morning and talk on the 2 or 70 m/cm machine to people
who I could conference in on a cell call...but we enjoy it.
As for repeaters holding up. when IKE came through Houston the Bay Area
repeater (both of them and the APRS machine) turned into a pretty busy
communications hub. The cell tower next to us lost power but we had good
generator power and had not even started to seriously invade our "potential
energy reserve" when the juice came back on. There was a bout 12 hours when
both machines were running as hard as they could with traffic.

A handheld 2M HT and a simple antenna improvement for it are all that is
necessary to hear ARISSat-1 - as designed.
Definitely a school project - as schools across the planet are anticipating
the deployment. Especially schools in Russia and the U.S.

Surely that's true of *any* trunked system, though? Once you've filled up
all the traffic channels (or timeslots) it's going to start moaning about
being busy.
You don't even need a disaster to do that - stand near a football ground
just after a game finishes and everyone is coming out, and try to make a
call. The city where I live has just switched all their traffic wardens
over to mobile phones - it's a disaster when there's any large event on.
The MPT1327 system keeps going without a blip... (well, except when BT cock
up the tie lines)

Exactly,
It happened in Dunmore East (http://www.waterford-dunmore.com/tourism/web)
last Sunday morning. Huge crowds descended on the village to watch the Tall
Ships (http://www.waterfordtallshipsrace.ie/) leaving Waterford Harbour in
the parade of sail. For several hours it was impossible to send text
messages or maintain a voice call (the system suckered you into thinking it
was working by ringing, and then the person would answer, the channel lasted
long enough to say "hello").
We brought our communications network with us, so it wasn't a problem for
us, but it was an eye opener for the County Council people who were
'coordinating' via mobile phone.

I remember one winter sometime around 1998 there was a real bad ice storm
on the east coast. Canadian hams were using AO-27 to pass health and welfare
traffic. There was no electricity up there for months, propagation was bad,
there was no other way for some. I passed some traffic myself, sent out an
email letting relatives know that they were ok. And yes while this was
trying to go on, people were still calling CQ, and asking for grid squares

Jerry,
Your feelings on this are polar opposite of mine. I am literally on the
edge of my seat waiting for this satellite to be pushed out. There are soo
many interesting things about it, I can not comprehend how anyone could be
dis-interested in it. If you're an individual (or group at a school) with
an 2M HT that can Only Receive, look at what you can do:
- listen for the CW beacons
- listen to the voice announcements
- listen and decode the SSTV signal
- listen for the telemetry signal and examine the plethora of telemetry
data available
This is an amateur radio satellite with flippin cameras on it, how cool is
that!!! I think having the possibility of getting a snapshot from space,
using amateur radio technology is pretty cool! But then again, I have been
known to get overly-excited about simple things. AMSAT engineers could have
easily said "Ahhh, that's too much work... blah blah" or "Bah!! There isn't
enough time..." but instead they got it done and it's on the ISS ready to
go!
I would be focused on getting your station ready to use it. Or, maybe
helping someone else get a station ready for it. It's all a matter of
perspective. I think everyone should be excited about this, I know I am!

The fast majority of people using cellular services don't understand the
channelization that occurs and how limiting that is to the total number of
people that can use a particular cell at any time.

Thanks to all who have emailed and requested skeds with me from JN88 in
Slovakia. After a series of rig and antenna issues, I am now back on the
sats, with several QSOs today with good reports.
I will try to make a test AO-7 run tomorrow when I have a common footprint
with North America. If all goes well, I will take my rig and a 70cm antenna
with me for the weekend when I go the the OM1HQ club station in JN89 for the
IARU contest on HF. They have a 2m beam at the club. Those of you who
worked me last year in JN88 should be on the lookout Sunday if you want this
new grid.
No promises or skeds yet, with the bad luck I've been having anything can
happen. But I still have more than 3 weeks left here and hope to have some
sat contacts with North America.
Last year, best DX was Ohio to the west and Virginia to the south.

Hi Jeff, KB2M
The next time please use linear satellites like VO-52, FO-29 and OSCAR-7
so that you will pass your serious emergency traffic in one frequency and
the others will still calling CQ and asking for grid squares into the
adiacent frequencies.

Thanks Clint,
It's been a challenge keeping it running. When Cell #2 goes, most likely we
will be done. We need Fox ASAP, along with FunCube, UKCube, Kiwisat, and the
other imminent projects, and a gift launch for P3E.
Please, if you use the satellites, or like the program, donate when and what
you can.

If the power fails to the cell site, it shouldn't make a difference.
They're supposed to have 48 hours of battery backup.
Up here at 58?N most cell sites cover a huge area and have no mains power,
so they run on a diesel genny that gets filled up once a week or so.

I once suggest this before and got little traction.? We all have what I call
"round to it" projects.? When in reality we'll never get round to it.? How
much "stuff do we have just waiting?? I suggest we simple float this stuff
on ebay, craigslist, this bb or whatever.? Then donate the funds to AMSAT.?
I mean even Clint bought some AMSAT stamps awhile ago.

Thanks Clint,
It's been a challenge keeping it running. When Cell #2 goes, most likely we
will be done. We need Fox ASAP, along with FunCube, UKCube, Kiwisat, and the
other imminent projects, and a gift launch for P3E.
Please, if you use the satellites, or like the program, donate when and what
you can.
