Thank you to Kerry, WC7V, for letting me know that SO-50 is still alive
and well this morning. And he lives in Montana where it was only 5:30 in
the morning at the time!
If you have been scared off of SO-50 due to crowded conditions, try a
morning pass. "Not crowded" is an understatement.

The following was drafted while I was aboard the Pearl but I didn't have
internet access so I couldn't send it off. I'm home now and uploading to
LOTW, but I will wait on this upload until I hear from you.
QST: to those who worked me when I was in CN70 on May 3, 2016 of the SO50
pass of 1326-1338 UTC please be advised that my recorder did not turn on and
so I do not have an audio recording of that pass. When I discovered the
problem I jotted down those calls I could remember. Therefore, if you
worked me please send me an email (lee.ernstrom@xxxxxxxx.xxxx with your call
and the UTC time of contact. The following is a list of the stations I can
remember. If I missed you please send me an email...

A few weeks ago I solicited some advice on this forum about decoding EO-79
packets. Thanks to that helpful advice I kept at it,
taking a yagi out into a field on Wednesday and finally getting multiple
decodes.
So imagine my surprise when I recorded a pass just now with only the discone
-- the antenna through which the signals had always been too weak to decode
before -- and, out of nowhere, the packets came booming in:
http://i.imgur.com/6977bHK.png
This was an even better result than the pass earlier this week using the yagi!
So it looks like I've got this process sorted out. Now to expand to other
birds, other modes...

Just wanted to thank the AMSATJournal staff and contributors on a very fine
publication.
While each issue provides valuable info and updates, this particular month's
edition
has been an enjoyable read, covering history, current product reviews, and
a look ahead.
Well done!

Hi all SAT lovers,
I have completed my LOTW uploads from our west coast cruise aboard the
Norwegian Pearl. I had some glitches in the operation ie, announcing CN68
when I was really in CN78, failing to turn on the recorder when I was in
CN70, uploading my contacts from CM85 to LOTW but recording my location as
CN85 (I have reloaded those contacts and made the correction).
I noticed that there were a couple instances when there was QRM, QSB, and
QRN on my recording and there were a couple places where I made the contact
but couldn't make out the call when I listened to the recording. If you
see that I have missed uploading your call then send me an email with the
time and date and I will fix it.
Thanks for all the fun,
Doc, WA7HQD

Hi Enzo.
If you run it with either the FUNcube dashboard or preferably SDR# you will
be able to see what type of problem you have from the spectrum display.
Enter the frequency for a known local signal....beacon / repeater / airport
etc. and you'll be able to see if you have any signal at all.
Turning the bias tee on and off will show if you have problems communicating
with it. - Just see if you get 5V on the SMA.
Or you can turn the LNA on and off, this will increase or decrease the noise
level from your speakers
Weaker than usual signals on the expected frequency ( - 30/40dB) can
indicate either mechanical damage from excessive pressure to the SMA. (This
can crack a SMD capacitor)
Or a blown front end MMIC which can happen if its been transmitted
into.....Although they are surprisingly rugged to RF.
Thanks
David
Hello to the list,
Please i have a FCDPP that doesn?t work properly.
Any chance to send it for a check and if need a repair?
I have tried to leave several messages on the http://www.funcubedongle.com
Site but did not get any reply.
Any help will be really appreciated.
Thanks

Good afternoon,
I was able to decode 9 packets of telemetry from AO-73 via FO-29's
transponder at 1647 UTC today. Signals were unusually strong as the
satellites were close together, so I decided to try feeding my
recording of the pass into the Dashboard.
See an image of the Dashboard and a screenshot from SatPC32 showing
where the two satellites were at the time here:
https://twitter.com/PRStoetzer/status/728631296658944000
I was using just an Arrow antenna, High Sierra Microwave LNAA432
preamp, and an FT-817.

Heard the astronaut side of the school contact really well here EM79. I
made a recording but I haven't checked it out yet.
Max elevation here was 28 degrees but with nice flat area I could hear
ISS horizon to horizon.

Hi All,
FUNcube-1 has just switched to continuous amateur mode with the transponder

AHHHHHHHHHH...........
you beat me to the punch!!!!!!!!!!!!
We also received AO-73's signal via FO-29 today at the VTGS (we only got
6 packets!).
We did this as part of a class project for ECE-4644 Satellite
Communications, and the students that were with me during the
observation of the event received a half letter grade bump on their
grade for the class project. The student project was to build a piece
of simulation software that would predict when the chain events between
the two birds would occur and to compute the doppler offset and link
budget in one second time steps for each event in a two week period.
I'm proud to say they not only predicted when the event would occur,
they were SPOT ON in the doppler computation (from around +5 kHz to
about +10kHz offset from center of FO-29's downlink here in Blacksburg VA).
Score for Amateur Radio supporting Students' Education!
And Congratulations Paul! If I'm not mistaken, this is a first ever in
Amateur Radio satellite work, reception of a crosslink? Way to go!

Zach,
Probably the first telemetry relay, but not quite the first relay. I recall
literally decades ago
there was a relay, probably but not definitely from 70 cm to 2 m to 10 m.
It might have included AO-7
in its first incarnation. Perhaps some of the really OTs might recall the
details. Still, a great
achievement. Especially calculating the hop to hop Doppler!
73s,
Alan
