For the Peace Conference, the Academy was cordoned off, students
prohibited from going on that side of the Yard, and photos of
the proceedings were prohibited. The Academy was locked down
the whole day, including all WEB page servers.
To see the Satellite Technology, however, I put together this
web page for the students in our Satellite Labs:
I've been struggling with packet satellite since day one and I have two
questions pertaining my Amateur Satellite Ground Station.
1. I'm new to MixW and very interested to know more about MixW
configuration to receive Packet Satellite telemetry specifics for OSCAR. I
have bought one complete package which included MixW software, RigExpert
plus and interface cable. Unfortunately, till today I can't even decode any
OSCAR telemetry either by using RigExpert or TNC.
2. My next question is how to operate my station as APRS? I'm be able to
receive somthing from ARISS but the signal is not digipeated. The data as
> HELLO FROM 9W2NRL
> RS0ISS-4/SGATE>CQ>UI,R,F0 (1199 baud):
> >ARISS - International Space Station (BBS/APRS on)
How do I verify the packet is really transmitted on air?
My station is equipped with X-Yagi Antenna, UHF Preamp, IC-921, FT-817 and
KAM-XL. In the software part, I used GSC and WxTrack for tracking and MixW.
A million thanks for your suggestion and guidance.
Today I was monitoring the LO-19 cw beacon on 437.125 and noticed that there is always a small
signal present between the cw telemetry blocks.
The beacon transmit about 750mW. The small signal is about 30db down, so I guess it must be around
1mW. Does anybody have some more info (power?) about this unsupressed carrier signal?

Some time ago there was a discussion about formatting of ANS buttetins
from Lee KU4OS.
I'm finding it impossible to read some of these bulletins. Four recent
ones are 245, 266,308, 329. I think that these may have been sent as
MIME encoded attachments, instead of being sent in plain text.
Here is a bit of what my text based mail reader sees -
Could these bulletins be resent to ANS as plain text? Alternatively,
are they available for download anywhere. I couldn't find the complete
bulletins on the Amsat Website, only individual items of news. The
archive didn't include any for 2007.
Any help would be appreciated.

Switching to LMR coax with an amp near the antenna and I have a lot of hardline I want to unload. About 125 feet (one piece) of Cablewave systems 16733-810921-001 (not sure what that number is) FLC-78-50. Also about 300 feet (about 4 pieces total) of GCC-AL-500P 1/2 inch. Pick up or I'll meet you half way if you're within 150 miles of Seattle. I don't know what this stuff is worth, will sell or trade for whatever ( I could use a vhf/ufh mobile). Also on ebay some tunable connectors for 7/8 hardline. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=110199802903&ssPage…
XYL says I'm collecting too much stuff.

What you want to look for is the propagation effects of weather on the
frequencies you are using on the satellite. ARRL has some info on its
site for 2 meter and UHF. There are other sites that focus on microwave
freqs such as 1.2 and 2.4 Ghz. As you found googling "sats and wx" are
going to bring up sites related to
The weather effects will be the same between sats and terrestial use.
It is possible to have weather caused refraction on your up link or
downlink causing the signal strength to be have higher loss then normal
line of sight.
Hope my ramblings help.

My reception on the LEO's has deteriorated over the last week. During
period we have had some rain but mostly overcast with thunderstorms
50-60 miles. I have checked all the connections, etc on the antenna. The
noise is sporadic hum and lots of QRN.
I have searched for " effects of wx on amateur sats" but turned up
Was hoping someone could point me to some info on wx and sats; I know it
some effect on Direct TV etc but need to get to the source of my
is there with the PA on and off...

ANDE Re-Entry Campaign:
The ANDE-MAA satellite (Nav Oscar - 61) will de-orbit in the
next few weeks but is fully operational. We encourage activity,
because while it is in use (2m packet up/down), then it is awake
and sending telemetry. We want to capture the most telemetry to
see if we can catch the thermal changes as re-entry approaches.
Who can capture the last telemetry frame?
The most important telemetry is that which is fed live by IGate
into the APRS-IS system. Because that is automatically logged
and time stamped.
You can verify your data got in by looking at the
http://pcsat.aprs.org web page after each pass.
If you manually capture any packets, Please take special care to
accurately LOG the TIME of any packets received especially in
the final day prior to re-entry. See the contest page below for
how to submit entries:
Here is the ANDE Operations web page. It has links to live
And this one is the CONTEST for data collection and operations
sponsored by PA3GUO and DK3WN:
Any APRS station that is also on the internet can contribute
telemetry by simply QSY'ing their normal APRS rig receiver to
145.825 on that final day.
If you do not normally run APRS or an IGate, then you can simply
download ALOGGER.EXE which is a full up IGate designed just for
satelite gating without having to learn APRS. See Bill's web
ANDE is coming over the northern latitudes in the afternoons and
evenings local sun time, but this pattern moves earlier by 14
minutes per day.
Just monitor 145.825 MHz.
Do any of the tracking programs have a audio record function. I would like
to track multiple satellites, tune my ft-897, and record the audio. Right now
the program that I am useing to record audio has to have the start and stop
record times manually programed into it for each bird.
