Been listening to AO-85's transponder today, I personally cannot get into
it, But I do collect ALOT of frames when someone activates the transponder.
This last pass I got 45 packets in a 5 degree pass and average about 50+
packets a pass (When Transponder Is On) so I have been collecting packets
like crazy and lead the 90 minute leaderboard on the tlm website! Other
than that I do not notice anyone having low audio now unless the people are
using narrow FM. I am listening to every nightly AO-85 pass (Even If Its
Late Hi Hi). Sounds great Jerry we just need to work those few bugs out!

Hi !
With help from K4SQC I finally got some AO85 telemetry to decode! After
the 186 payloads were decoded (high speed on that pass!) and the pass
was complete I realized "upload to server" was not checked, so I checked
it.
Is the information below accurate, the already decoded telemetry will
not now or ever upload to the server? We did record the pass in HDSDR
so I should be able to follow the path Scott took but I'd like to verify
this before "dumping" the decodes.
Thanks!

I didn't really know if there was any benefit in that, but I told myself
that I was keeping the waveforms on the Fox Telem software as "clean" as
possible in hopes of more decodes. Similar apps give some level feedback so
you'll know if you are feeding it at the right volume, but it's still a
really nice app.

If all goes well Kjell should be out of his space suit and on the radio at

All,
I've reached Holly, CO and will be here for the next two days. I
activated EM17/18 and EM07/08 earlier today, thanks for all the worked
me on those passes.
Also tonight of interest I performed a demonstration on XW-2E and XW-2F
for the landowners of Schwerdfeger farms near Coolidge, KS (in DM97).
The Schwerdfeger family owns the land where the convergence of DM97,
DM98, DM87 and DM88 all come together, the intersection of the 102nd
Meridian and 38th Parallel. After the demonstration they granted me
permission to operate from the convergence spot tomorrow afternoon,
where I will activate all 4 grids in one swoop for all the grid hunters
out there. All 4 of these grids are quite rarely heard on Satellites,
and it will be an opportunity that will likely not present itself again
anytime soon.
The 3 passes in particular I will work are as follows:
AO-7(B) 2054z 10/23/2015
FO-29 2109Z 10/23/2015
AO-85 2158Z 10/23/2015 - (Contingent upon the Amsat Engineering folks
not needing it for testing)
I will likely be working random other passes from single grids the next
few days as well, so if you can't make the 4-pack, there is still hope.
Until then, hear you on the birds.
73!

These polarity switching harness' are in excellent condition and complete

and a 435-40CX a 40 element 435 MHz circularly polarized crossed-yagi. Had
purchased them several years ago as a spare to the ones that were
deteriorating on my KLM's. I sold the KLM's, but forgot about the extra
polarity switching harness'. They are in very good shape. I would like to
get $100 plus shipping for them. 20% of the $100 will be donated to AMSAT.
Let me know if you want them as I'm not taking them with me to Florida and

Daryl,
The below instructions will work, but you do not need to delete your data.
Just replay the pass with upload to server on. FoxTelem will not store the
duplicates locally, but it will queue them and upload them to the server.
If your local count of payloads increases, then it means you managed to
decode a few more frames.

Hello Daryl. Hopefully someone with more knowledge that I have will reply,
but it worked very well for me.
Don't forget that you can make a copy of your log folder before purging the
data from inside the FoxTelem software so that you can put things back if
you don't like the results after re-running the pass from your .WAV recording.
I'm not a programmer, but if it's do-able, I think it would be great if
future versions of all the various cubesat telemetry applications have the
ability to store a download and then upload it when the computer is back on
an internet connection. Of course I realize that would add complexity since
each packet would have to have a timestamp if it's not being uploaded in
real time.

Uploaded?
Hi !
With help from K4SQC I finally got some AO85 telemetry to decode! After
the 186 payloads were decoded (high speed on that pass!) and the pass
was complete I realized "upload to server" was not checked, so I checked
it.
Is the information below accurate, the already decoded telemetry will
not now or ever upload to the server? We did record the pass in HDSDR
so I should be able to follow the path Scott took but I'd like to verify
this before "dumping" the decodes.
Thanks!

my I/Q file that last time, I reconfigured SDR# as well as the VB-Cable
audio link to both work at 48,000. Sure enough, I decoded many more packets
than I had previously. Going forward I'll capture the data with those
settings.

again with it set to high. However, I realize now that I could have easily
paused the playback in SDR#, stopped the Fox Telem input, switched to high
speed, and resumed the playback.

configuration will be to only use the Fox Telem software during a fly-over
to give me some feedback as to how well I'm receiving. I'll then dump the
resulting payload and replay the recorded I/Q file with an active internet
connection and the Fox Telem software set to upload. It would be wonderful
if the software would "store & forward" the packets once online, but this
might be a blessing in disguise as there is every chance that I'll have a
better result decoding under controlled conditions where I'm don't have my
hands full with an antenna, etc.

have any success with that and I actually liked replaying my recordings in
SDR# so that I could verify that I was centered on the carrier and make
minor frequency adjustments. I was also tweaking output levels on replay.
I didn't really know if there was any benefit in that, but I told myself
that I was keeping the waveforms on the Fox Telem software as "clean" as
possible in hopes of more decodes. Similar apps give some level feedback so
you'll know if you are feeding it at the right volume, but it's still a
really nice app.

At the 21:57 UTC U.S. pass of AO-85 tonight October 23 we will conduct a
test with the transponder. Please do not uplink during that pass over
the U.S.
We encourage you to copy telemetry with FoxTelem during this pass and
have it sent to the server, to aid in analyzing the test results.
Thanks!

Subject: [amsat-bb] Big tracking UHF pocket income?
Message-ID: <93220999c4005f707317a3f83dddca69@xxxx.xxxxx.xxx>
Content-Type: text/plain; charset=UTF-8
Anyone with an EME UHF antenna want to earn some maintenance money for
their Ham radio addiction?
I just became aware of (unverified yet) that there are small satellites
being built with UHF downlinks but that need EME size ground stations to
bring down their 3 MHz wide science data. The most expensive part of their
missions is the $$$ sent to the big NASA tracking networks.
During EME contests we see lists of hundreds of Amateurs with huge EME
antenna capability? I wonder if there is an opportunity here for some
individuals?
The UHF is not in the amateur segment but they thought it was overlapping
the 450-470 MHz LMR spectrum. This makes sense, because a 1W transmitter
spreading its energy over 3 MHz from 500 miles away from the ground is not
going to interfere with anything in the LMR services.
But also this is probably too far from the normal narrowband ham EME
activity at 432 to have any gain up at 460 MHz. But for those EME hams
with dishes, a simple feed change might give them a source of income.
Note, this is nothing to do with amateur radio, or rules, or anything.
Just a thought, that if you have a big dish in your backyard, you might be
able to make use of it for reception?
Is anyone subscribed to an EME email reflector that is aware of the number
of very large EME dishes ?
Just another crazy thought?

Hi All,
Just to report that AO-73/FUNcube-1 is now in manual amateur mode for the
weekend with the transponder operational continuously.
We plan to revert back to auto mode on Sunday pm, as usual.
Please enjoy and have fun
