Hi Bill, W1PA
The following page is not a marketing web page but an
official AMSAT-NA web page

If you you mean that the the "emergency" access ability used
by AMSAT as part of the justification for funding or launch
vehicle access it doesn't mean it works for that in any practical
situation it is like to say that AMSAT tells falsehood to NASA
and ESA but as far I know AMSAT is not used to talk nonsense.

Sorry Domenico,
the link you provide is on the "old" Amsat-NA website and is a copy of the
Indian website:
http://www.amsatindia.org/hamsat.htm
Nothing more, nothing less and Bill's point is very valid. While amateur
radio has a great history of emergency services and is one of the true key
public services, amateur radio satellite are currently not part of it. That
does not mean they cannot be used, but they are just too limited. There is
a reason why 99.9% of emergency services within NA using amateur radio are
based on ground services trough VHF/UHF and HF and not satellites!

Yep, I was going to raise the same point and link. They list the following
"benefits":
- providing Satellite based Amateur Radio
Services/meet
the long felt need for the Amateur Radio Operators of
South Asian region (especially a mode B bird)
- bring Satellite
Services within the reach of the common man and
popularize Space Technology among the masses.
- stimulation of technical interest and
awareness among the younger generation by providing them
with an opportunity to develop their technological
projects
- providing a low
cost readily accessible reliable means of communication
during emergencies and calamities like flood,
earthquakes, etc.
I never said the last one is a "falsehood". I am suggesting it does not hold
anywhere near the same weight as the first three.
I have never been in a tornado. But I would suggest that those hams in the
impact zone no longer have access to any working equipment, which means hams
in the surrounding areas are coming in to help, and have the choice. If I
was going into the impact zone and had the choice of what communications I
might bring, it would be
- a portable cell site
- mobile/HT VHF/UHF
- mobile HF
...in that order. A portable satellite station would be a distant fourth.
If you read the summaries in the aftermath of Joplin, amateur radio
(VHF/UHF) played a critical role in the minutes leading up to, and the hours
after the tornado tore through. Then mobile phone, mobile date, and social
media took over when the mobile cell sites came on line.

I have been around tornados, and their aftermath. The devastation can be
complete, but the area devastated is very small (a narrow strip). An
enormous tornado is a mile wide... All of the infrastructure two miles away
is generally completely intact. Once the overload subsides, your cell phone
will work just fine in the worst part of the destruction. Land line phones
a mile or so away will all work. Handhelds and VHF/UHF mobiles are handy.
There generally isn't need for much else.
Hurricanes are a completely different story.
73,
Joe

Message-ID: <519DE7D7.5020105@xxxxx.xxx>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Good Day everyone;
hopefully by now everyone is aware that AO7 is going into an eclipse as
it passes over Antarctica and with the loss of sunlight on the solar
panels the satellite is going into a Zero Voltage System Reset, and when
the satellite comes back into the sun it is starting up in Mode B every
time.
Information from others have said that that is by design, but some of
the reading I have been doing, suggests that the mode is random. The
observations made so far indicate that it appears to be by design and
NOT random.
I have noticed a slight variation in the Doppler adjustment from my
previous program settings and there have been some reports of slight
audio distortion. I am currently leaning towards the frequency
variations and audio to being caused by temperature variations due to
the lack of solar heating as the satellite passes over Antarctica, once
again these are just my opinions.
Software predictions indicate that the eclipse periods will get up to
about a maximum of a 3 minute period at the longest and it will be
interesting to watch for any variations in satellite behavior at that time.
/*For now we have Mode B repeating, enjoy it Mode B users and Mode A
will be back in a few weeks if everything stays like it is.*//*
*/
I hope I am not boring everyone with these AO7 reports.
Thanks to Alan; ZL2BX and Ib, OZ1MY for their updates and observations.

Hi Kevin...
If you go back in the list, about a year (or maybe 2, time flies), you
will see very similar discussions as AO-7 went into full eclipse. At
that time it always came out in Mode B until the eclipses shortened and
then it started coming out random, probably depending in what mode it
went in.
At that time the wobbling audio was attributed to excess loading of the
sat which was not presenting it's best panels to the Sun, but as her
data is scrambled it never was proven.
I hope this journey is as successful as the last one. A grand old bird.

See if this gets on the board
The Repeater/amateur group that I am a part of here in Houston has tagged up
with FEMA...we have gotten some money from them, access to various towers
through them...and as someone who is interested in amateur radio satellites
when the topic comes up there is this almost quiet giggle that most of the
people have. If we had an HEO that was available for reasonable times a day
well maybe.
During IKE, our repeater was one of the few in Southern Houston/Galveston
that stayed up. All our sites have emergency power and the system is pretty
robust. We had in place before the hurricane an agreement with FEMA And NWS
(and the FCC) where if necessary FEMA/ETC could come on our links and use
them as fi they were their own. Their FEMA's repeater is on the same
"stick" as ours, but it went down because the antenna mechanical connections
failed. So they came over to our 2 and 70 CM machine
I keep a pretty good electronic log of how the machines are used. The 2
meter normally "plays" for an average of about 12 minutes an hour (that
includes nighttime hours) and during the 18 or so hours FEMA was up on ours
it was playing at about an average of 22 minutes an hour. they even used
the phone patch an average of 5 times an hour!
Ike was actually pretty "benign" in terms of infrastructure damage (the cell
sites stayed up)...so we never got a solid test of our packet link to FEMA
HQ outside of Houston...
But it is hard to see a role for a satellite that flies over for a few
minutes and is not "there" most of the day...or even three or four of them.
After the hurricane FEMA cut lose with some more money for our site...they
are not keen on amateur satellites but they like TACSAT 4...one of the
reasons a group I am part of got an SBIR to play on Tacsat 4 was because of
FEMA helping.
We get an HEO (or had AO-10 or 40 or even Arsene) well maybe things change
until then not so much Robert WB5MZO

after the tornado tore through. Then mobile phone, mobile date, and social

I understand that if you have a serial port on the ST-2 you can program the
Pic 16f876a directly. I have an ST-2 with usb. Can I program Pic 16f876a
through the usb port ? Any help would be appreciated.
Thanks and 73
