It is indeed an additional handicap for those of us with Arrows and HTs,
and it took me about four passes before I could get a grasp of what
uplink frequency to use at what stage of the pass. But I eventually got
in there. (I had a lot of noise behind me, but I was copyable.)
I agree that SO-50 is much easier to hit, but if there's one thing most
hams like, it's a challenge. If anything it's an incentive for me to
think about upgrading my gear.... :)

Interested in hosting an ARISS contact? The window is now open from
2015-09-01 to 2015-11-01. These proposals will be for school contacts
during the
second half of 2016. Go to http://www.arrl.org/hosting-an-ariss-contact
or http://www.ariss.org/apply-to-host-an-ariss-contact.html for full
details.
To help organizations in preparing their proposals, the ARISS Program
Coordinator will offer hour-long online information sessions. These are
designed to provide more information regarding US ARISS contacts and the
proposal
process and offer an opportunity to ask questions. While attending an
online information session is not required, it is strongly encouraged.
These will be offered Thursday, September 17, at 2000 UTC; Tuesday,
September 22, at 2000 UTC, and Wednesday, September 30, at 2300 UTC. Advance
registration is necessary. Email ARISS (ariss@xxxx.xxxx to sign up for an
information session.

For those interested in this project there is another opportunity for
Central US tomorrow
An International Space Station school contact has been planned with
participants at Daggett Montessori School K-8, Fort Worth, Texas on 29
Oct. The event is scheduled to begin at approximately 14:12 UTC. It is
recommended that you start listening approximately 10 minutes before
this time. The duration of the contact is approximately 9 minutes and
30 seconds. The contact will be direct between NA1SS and K5COW. The
contact should be audible the mid U.S, and adjacent areas. Interested
parties are invited to listen in on the 145.80 MHz downlink. The
contact is expected to be conducted in English.

AMSAT,
???? Does AMSAT HQ/Server location sport Egg-Beater antennas or an
auto-tracking SAT setup. Has AMSAT considered streaming FM SAT RX over the
web when a SAT flies over AMSAT (priority given to AO's) ?
I'm sure it would be interesting to all, assist newbie learning curve, allow
verification of tracking program setup, and give first hand training of what
that SAT sounds like as well as real-time HAM OPs on that SAT.? Web audio
streaming would only happens when a SAT is view-able (otherwise teh stream
could play an AMSAT voice ad). Just an idea.
?Best regards,??

Makes me think of SATNOGS. You don't get a stream but you can get
audio for a lot of passes after the fact, most passes theoretically as
they get more stations up.
Example:
https://network.satnogs.org/observations/66/
Another issue with streaming online is there is almost always
buffering/delay. So it wouldn't help as much in hearing yourself
getting in because it would be so confusing. If you've ever tried to
listen to yourself speak over any delayed system (like broadcast).
It's very confusing.

I know he DarhVader affect that happens on FM repeaters with audio delay
when listening in full duplex. I was not intending for this streaming to be
used in that fashion as also my SAT pass and AMSAT SAT pass will be very
different due to our locations.
Web streaming would be used as I mentioned in my initial posting. "Assist
newbie learning curve, allow verification of tracking program setup, and
give first hand training of what that SAT sounds like as well as real-time
HAM OPs on that SAT." Secondary could be for AMSAT voice ads during SAT dead
times.
Maybe AMSAT-SatPC32 program could be modified to not just control a radio RX
frequency but during the pass SatPC (using AOS/LOS Alert functions) would
toggle PC audio amplifier to pass the RX mic-input audio to the PC-out
speaker/Internet streamer. Nice PR for what SatPC32 can do for new buyers. ?

Well we already have a lot of recordings here:

Not sure it's automated for every pass, though.

I guess it would be more exciting to listen to a live stream as a
newbie. You could do pass predictions for the remote site yourself and
see how they match up with the actual AOS/LOS and such. Perhaps you
could even put a camera on the antenna to watch it move around (if you
had a tracking setup). That would be pretty cool.
You can get some of this effect with the WebSDRs, but none of them are
sat specific AFAIK

Hello Loon,
The difficulty you are experiencing in trying to access AO-85 is real,
but it is not because of the U/V configuration. The UHF uplink takes
some getting used to because of the greater Doppler effect and certainly
full duplex is what you will want to use in order to be sure that you
are on frequency and being heard. The VHF downlink is very strong and
can be received even with an omni antenna, and in fact Tuesday afternoon
I was receiving it loud and clear with my Arrow antenna pointed toward
the ground as I rested the antenna while I made some notes on my
testing. In addition most users have found that the uplink receiver
frequency is about 5 to 10 kHz below the expected 435.180 MHz, most
likely due to the warmer temperatures than we modeled and tuned the
receiver for.
We have, since shortly after launch, been aware of reports of a lack of
sensitivity on the receiver (uplink) for AO-85 and we have been testing
that and investigating scenarios for a cause or causes. That is why
AO-85 has not been officially commissioned yet. You recall that we
talked the other night on AO-85, I was testing with various power levels
and that is why I asked about your setup and experience as well, to add
it to our knowledge base.
We have indeed identified some things with the help of the Fox-1Cliff
flight antenna configuration as a comparison, and are making changes to
Fox-1C and Fox-1D that should improve their receive sensitivity and
CTCSS detection. We will characterize their receivers (and
transmitters) frequency change for the higher temperature range that we
are experiencing on orbit so that they should be much closer to the
intended numbers. Once we have determined and addressed the causes that
we find you will find more specific information about it in the Nov/Dec
AMSAT Journal. I am writing about all of the post-launch AO-85
commissioning and testing activities, in detail. Some of the details
will be released in other AMSAT news outlets as well.
Thank you for posting your experience. It helps us to improve.
Jerry Buxton, N?JY
