Hi Ron, KA4KYI
If you are into a real emergency you have not the time to wait for a
possible FM satellite pass and have a chance that someone is
understanding your problem,your location and how to hep you into
the QRM made by a lot of stations calling in the same channel and
all at the same time.
A linear transponder in SSB plenty of room for FDMA (Frequency
Division Multiple Access ) would be better but not ideal.
In emergency situation novadays a cell-phone is much much better
and reliable.

Unfortunately, we have a lot of people with ham licenses who have never
understood or seen the complexity behind cellular networks to understand how
fragile they actually are. Sure, the cell site is wireless to you, but it has
power and wired telephony requirements that put it several steps on the risk
ladder above a ham repeater, and extremely high risk for failure compared to
simplex radio comms.

When the towers are damaged or the power fails to the cell site, cell

That's not it at all as I see it. Does anyone on this list really
believe when aliens attack that repeaters will survive but cellular
networks will all be done?
Network survival is not the pertinent metric; network *recovery* is.
Bob mentioned Haiti. That is a good example. How many active
repeaters do you think are in Haiti? How many do you think survived
the Earthquake? How many repeaters are in <insert very poor
third-world country here>?
The bottom line is setting up an RF station to communicate vital
information is an order of magnitude faster than to rely on the cell
companies to restore service. That's the issue.
Now tie this to AMSAT-BB:
If I could switch from using a local cell to one based on
geosynchronous satellites than RF would probably not be my first
option since cell phones offer more forms of communication than a
radio (think HT).

Jump to conclusions????? Plenty of time has passed since the "test" and
this information should have already been available. Obviously George's
statement about "Roscosmos forgets that they have PARTNERS in this venture"
is correct.
I don't believe we are "jumping to conclusions" just because we expect
somewhat timely answers.

See- you jumped to a conclusion- The Russians DO NOT have to answer to you
or anyone outside of "their" circle- Once again, the ONLY voices you should
listen to are AMSAT staff since they are the ones with the CORRECT answers.
Timely answers are not in the country in question's vocabulary- You watch
too much CNN type news.... Besides, majority of the people that will use a
given satellite have never paid into it. (My unscientific research)

If what I just worked now on AO-51 is "deteriorated performance" with one

The issue here is not the failure of the cell site, it is the 10 million
people that all try to use their cell phones at once. It takes days for
people to get their "urgent calls through" before the load goes down enough
to have any hope of getting in. But like in Haiti, even after a few days,
the emergency persisted and still everyone needed to use their phones for
urgent requirements and so the load on the few hundered cell channels
persisted....
At least until most people's batteries went dead (due to no power) and only
after most of those phones became useless was the demand low enough for
those still with enough charge to get a call through.
Again, this is my assumption, not known to be fact. But the fact of
cellphone LOAD after a wide area emergency totally blocking service is
pretty much fact.

Actually, Bob B. said just the other week that they did monthly
emergency nets on one of the FM sats and it was organized and worked well.

For all the folks who were screaming "SSB", let's compare the number of
users using AO-51 alone over the past couple of years to the number of
users for all the linear sats in the same timeframe. I'd much rather
AMSAT "blow its wad" on a crowded FM satellite then a linear one no one
uses.

Thankfully they did, or there probably wouldn't be an Amsat today.

Mother Nature has provided some pretty "biblical" disasters in recent
months...
Joplin, Haiti, Japan... we had our own bout of tornado?s here in central
MA last month (in fact, I live in the the path of the ?53 F5 Worcester
tornado, which until Joplin, had the dubious honor of having the most
fatalities.... yes, in Massachusetts).
I think it would be pretty straight forward to review each, as an
organization, or on your own, and make an honest assessment of what role
Amateur Radio played in the aftermath of each, in duration, response, scope,
ability to get back up and running, and impact, especially against the
?other? media... cell, internet messaging, other radio services, and social
media. Then judge 6-12 minute access to a moving, single-channel repeater
five or six times a day (assuming you have the means during a disaster to
know when the passes are) against the rest.
Also, keep in mind how many will or could have access to ham radio, and how
many have access to the rest.
I would love nothing better to serve my community during a natural disaster,
via VHF, HF, or even satellite. But how bad does it have to get before ?all
else? really does fail, or not come back up quickly?
