Hi Mike,
For the most part, the only bird currently running the "store and
forward" pacsat PBBS system is AO-51. It's up and operational,
depending on the schedule, at 9600 BPS. I find the "challenging" part
is the L-band uplink--even with around 25 watts at the antenna, my
house and TREES get in the way and make the uplink difficult. Good
old Wisp still works with this satellite. Few messages are actually
being passed these days. The store/forward packet system on AO-51 is
used a good bit by the command stations for telemetry downloading,
though.
GO-32 hasn't been running its 9600 BPS packet system in months---it
has been sending telemetry at 30 sec intervals off and on lately.
I think that's it at the moment...
73,
Mark N8MH
________
"Does anyone do Satellite packet? If so what kind of TNC is needed. Can a
Kam KPC-3+ used for VHF packet work? or do you need a different TNC.?
Are there many birds that forward messages around the globe like years
ago when pacsats were famous?
Thanks
mike

Tom WB8WOR thought you'd like to see this on wired.com
It sort of puts to lie the argument that transponders are hard to use. I
suppose it helps that they are in geosynchronous orbits.
I especially found this part interesting:
"I saw it more than once in truck repair shops," says amateur radio
operator Adinei Brochi (PY2ADN) "Nearly illiterate men rigged a radio
in less than one minute, rolling wire on a coil."

Yeah...?? I believe this has been going on for a number of years.? (I recall
reading about this on?another board.)
I believe the satellites in question use FM and geo stationary orbits and have
up links and?down links?in the miltary UHF band (225 thru 400?mhz.)?
Kind of makes you wonder what would happen if there was a geo stationary
amateur satlleite that was easy to use.?? If pirates will hack military
satellites then I doubt they would have any qualms about using an amateur
satellite.??

One of the primary justifications (for someone to subsidize the launch cost)
I have heard floated for a amateur radio geo stationary satellite has been
public service and emergency communications. How would those on the list
here feel about such a satellite should it come to exist being able to be
configured such that only authorized users could use it and others lacking
the channel keys would have no access, nor could they interfere. I'm
thinking for certain circumstances a jam resistant controlled access mode on
such a resource could be useful. What do you think?

Eric...the "instant" things start "being reserved" for a group of
amateurs...for any reason other then by regulatory action...we have started
down a very slippery slope that has no real end.
The FCC can and does "set aside" frequencies in serious emergencies for
special communications and then they end it...the frequencies belong to The
Republic. To be blunt..the way AMSAT has mishandled the amateur satellite
acquisition system since the ramp up to AO40 would in fact tell me that they
shouldnt be trusted with just about anything much less who gets on the bird.

Gentlemen,
I am trying to collect my equipment to work through AO-51 VS. Because my S
band equipment uses a 144 IF I am going to use another radio to handle the 144
mHz uplink and use the 144 mHz band on IC910 and IT-150 to handle the S band
downlink.
Seemed like a plan, But, my IT150 persists in processing both the 432 and 144
bands. My memory says I figured out how to handle this problem once, but
refuses to tell me what I did. I would like to work the current VS
configuration and am hoping that someone on the BB knows how to tell IT150
to ignore 432.

I ditto those statements entirely... Also would any frequency be taken from
other hams (most likely) or would an additional frequency spectrum be
allocated... Frankly Elitist suggestions like this make me think of Big

What I was referring to is the ability to set aside a few communications
channels on a temporary basis that would be relatively immune to
interference and kept clear for use by those who needed the resource such as
a net serving an affected area. I hope I wasn't misunderstood from that. I
was in no way suggesting that any spectrum be reallocated away from the
amateur radio service, only that a means may be considered for certain
channels to be protected from interference using technical means for a
limited duration while those participating in the sanctioned activity needed
the resource for the benefit of the republic as a whole. Is such a system
capability such a bad idea?

It all depends on how the elements are mounted.
If at 45 to 90 degrees from the crossarm, no propblem and use anything,
But if in the same plane then need insulated crossboom,
But then if you go insulated then do not run the feedline along it
either or you just defeated the purpose of the insulated boom.

Yes it is for the exact same reason that the Aeronautical service still uses
the (relatively) noisy AM mode as opposed to FM for air traffic control. The
notion is that someone one need can break into the system at any time with
emergency traffic... what you are proposing is a link wherein only elitist
users can enjoy the benefits. I suggest that with the FCC allocations of
emergency frequencies as needed, where needed, and the demonstrated ability of
hams to cope previously you are adding yet one more layer of non productive
regulation to an already overloaded system. As a founding member of SATERN and
more than once having been written up in WST for my emergency radio work, I
think I am familiar with both the problem and the solutions to them, please
don't reinvent a wheel that is already working.
A last comment, a LEO would be virtually worthless for Emergency NET
communications and HF is still a viable and reliable means of
communications... If there were a HEO or GEOSync bird up and if it was needed,
I am certain that it would be used... Nuff said.

What I was referring to is the ability to set aside a few communications
channels on a temporary basis that would be relatively immune to interference
and kept clear for use by those who needed the resource such as a net serving
an affected area. I hope I wasn't misunderstood from that. I was in no way
suggesting that any spectrum be reallocated away from the amateur radio
service, only that a means may be considered for certain channels to be
protected from interference using technical means for a limited duration while
those participating in the sanctioned activity needed the resource for the
benefit of the republic as a whole. Is such a system capability such a bad
idea?

Eric...the "instant" things start "being reserved" for a group of
amateurs...for any reason other then by regulatory action...we have started
down a very slippery slope that has no real end.

Indeed, my M Squared cross polarized Yagis need to be on a fiberglass boom.
The coax from each of them heads straight back into the air and forms a loop
down to the mast several feet below the elevation rotor.
E mail me direct and I'll send you photos if you want.
You'll be happier with a fiberglass boom.

It all depends on how the elements are mounted.
If at 45 to 90 degrees from the crossarm, no propblem and use anything,
But if in the same plane then need insulated crossboom,
But then if you go insulated then do not run the feedline along it
either or you just defeated the purpose of the insulated boom.

Hi all,
I found this line confusing....
"But then if you go insulated then do not run the feedline along it either
or you just defeated the purpose of the insulated boom."
My question is if you run the coax along an insulated crossboom, ie.
fiberglass, how could that affect the coupling of the transmission line when
the object it is being attached to is "insulated"?
