That only works if you also back-date the KEPS to the correct set for
the date in question, or else the satellite won't be where the
tracking software says it is!
The sat will be in a considerably different position with keps for a
year ( or any other period ) in front.

HI ,,,, ,,
i did some checking, looking for the KISS mode info from the "specialized
communications manual" i could not find one for the d7a, but the manual for
the d700e shows this info. i also ran into a document that stated it only
works on the d700e, not the d700a, i am not sure about the d7a i need to
unbox my HP LX200 to even attempt to try and test it out, maybe i will have
time soon. anyway, here is a good link for kenmore(hihi) radio manuals.

Hoping for a clean launch tonight. Go Discovery!

As always, Mission Audio is available on the IRLP Network on Reflector
Channel 9877.
Any IRLP-equipped repeater or station can provide audio by simply
dialing it up.
Currently 50 stations are linked in, with more usually around the peak
times of launch and landing...

Absolutely Gorgeous view from here in EL88pg, about 150 miles west of the
launch pad. I snapped a crappy cell phone picture from the parking lot of
where we were having dinner.
http://i139.photobucket.com/albums/q305/glasbrenner/PIC-0116.jpg Even with
the horrid quality, you can see the darkness, then sunset, then full sun
along the exhaust plume. That photo was about a minute after booster
separation.
I'm a native Floridian, and seeing a shuttle launch never gets old.

Great pass, we could see STS-119 for over a minute.
we could even see the SRB seperation.

True for ISS but not a big difference for the other ones at least it fairly

It was in the latest ANS bulletin:
SB SAT @ AMSAT $ANS-074.04
AMSAT-DC Spring Workshop April 25
AMSAT News Service Bulletin 074.04
>From AMSAT HQ SILVER SPRING, MD.
March 15, 2009
To All RADIO AMATEURS
BID: $ANS-074.04
AMSAT-DC Area Coordinator Pat Kilroy, N8PK reports on plans for the
AMSAT-DC Workshop to be held on Saturday, April 25, at the NASA
Goddard Space Flight Center in Greenbelt, Md.
A small "simulated satellite" kit will be built, tested and operated
by individuals attending. The completed kit, soon to be widely known
as a PICetSat II module, is a simple remote sensing unit that serves
as an expendable high-altitude small balloon payload. It transmits
downlink telemetry on the 70 cm Amateur Radio band.
Other attendees will provide and configure radios, computers and
software needed to receive, decode and analyze the PICetSat II
telemetry.
Pat says, "The format of this year's workshop is an experiment unto
itself for the few AMSAT-DC subgroup of members who are attempting
to organize such an event for the first time."
He adds, "This workshop may prove to be a fine training opportunity
for one to learn the basics of the design, construction, testing,
calibrating and operating an earth-orbiting satellite. All of this
in one long Saturday of fun!"
The planning sessions are being held each Thursday evening via a
toll-free telephone conference. If you wish to help organize or
execute the workshop then contact Pat by e-mail for the details of
connecting with the group on the telecon at Patrick.L.Kilroy@xxxx.xxx
as soon as possible.
The cost of each kit will be determined soon, along with the admission
structure. For example, being evaluated is $90 for a kit plus AMSAT
membership if one doesn't already have it. The details of the
registration process, workshop procedures and the associated costs
are to follow in a later bulletin and on the AMSAT-NA and AMSAT-DC web
pages.

Looks like the ISS will have to duck and cover again.
I try hard to maintain optimism, but I see this problem only
getting much worse in the future. Solutions?

NASA plans improved ?Internet in space?
* By Sean Gallagher
* Mar 09, 2009
NASA?s Deep Space Network is on the way toward becoming a true Internet in
space, thanks to the agency?s research and investment in software-defined
radios (SDRs). Also, the agency is preparing an SDR test module for the
International Space Station that will
be capable of connecting the station with an uplink of 100 megabits per
second.
Pat Elben, the chairman of NASA?s software defined radio architecture and
technology team (SAT) at NASA?s Space Communications and Navigation
directorate, told attendees at the IDGA?s Software Radio Summit that the
agency is setting up a new test platform.
The platform, named the Communication Navigation and Networking Reconfigurable
Testbed (CoNNeCT) will help NASA test waveforms based on the agency's Space
Telecommunications Radio System (STRS), NASA's own standard for space-rated
software-defined radio systems.
CoNNeCT will be added to the International Space Station in 2011, and
demonstrate communications between the space station and the Tracking and Data
Relay Satellite constellation that makes up the backbone of NASA?s network
with three radio systems -- the Electra radio that flew aboard MRO, the
General Dynamics Starlight radio, and the Orion radio -- the system being
designed for NASA's follow-on to the space shuttle.
NASA developed its own standard because of the demanding requirements of
space, where reprogramming a radio often has to be done remotely while the
radio is on a spacecraft traveling through the solar system.
That was the case, Elben said, when the Mars Reconnaissance Orbiter (MRO) was
launched. Technicians discovered the Electra radio aboard MRO, a
software-defined radio that was to act as the communications link to the two
Mars rovers on the surface, was getting interfered with by something else on
the spacecraft just before launch. NASA was able to launch the MRO and create
a software patch and upload it to the Electra radios aboard it while the
spacecraft was en route to Mars, he said.
Some observers have expressed concerns that suppliers might be reluctant to
write software to yet another SDR architecture ? the Defense Department?s
Joint Tactical Radio System uses the Software Communications Architecture,
which has been adopted by the Software Defined Radio Forum along with its own
SW Radio standard. Elben said NASA plans on buying more than 1,000 STRS-based
radios between now and 2025, but the price of these radios ? between $1
million and $5 million ? makes STRS radios a potentially $1 billion market
for radio developers.
Although NASA has deployed software-defined radios for years, starting with
the ?Blackjack? global positioning system receiver on spacecraft in 2000,
STRS will be part of the basis of an ambitious revamp of the agency?s Deep
Space Network. The re-engineering will be based on SDRs and on high-bandwidth
optical links, Elben said. It will also entail the use of software-defined
systems and a move to less-expensive arrays of dish antennas instead of the
old larger dishes. The new approaches are expected to make the network more
automated and less expensive.
In the 1960s when NASA first created what became its Deep Space Network,
?there was no grand vision,? Elben said. ?NASA?s goal for 2024 is a
highly integrated, IP-based disruption resistant network.?
Last November, NASA successfully tested Disruption Tolerant Networking (DTN),
an Internet Protocol-based network using store-and-forward technology to
ensure that packets of data would not be lost when being passed through the
Deep Space Network. The agency will begin testing DTN aboard the International
Space Station this summer.

Hi folks, wow was nice to get mycall on the ariss map, but I lost it. Not
sure if its because they turned off the iss packet for the shuttle or if its
still on, any one know?
I see other calls still on the web page.

typically ARISS activity is stopped while the shuttle is docked.
Thanks,

Your call probably got pushed off the queue. As new calls are heard, old ones
get dropped of the list of about 75 listed. Try this link for the last 200
stations heard. http://www.ariss.net/index.cgi?n=200
Packet is currently off since the crossband repeater is currently on. The
Kenwood D700 currently only supports one mode at time. The radio will soon be
powered off for EVA activities associated with the current shuttle mission.
