There are several satellites up and running right now ... from just being able to hear
some telemetry, to receiving and decoding telemetry - to working an FM repeater, and
monitoring/passing APRS traffic through the ISS!

Links to info on working AO-73, SO-50, FO-29, AO-7, and the ISS-PACKET are all on the
SAT SKEDS page at ... http://www.work-sat.com

In addition, some are hearing CUTE-1 and HO-68 - and more. Watch the Live OSCAR
Sat Status page - AND enter YOUR reception reports! - at ... http://oscar.dcarr.org/

There's more workable satellites in space than you might think! (grin)

And this great news just in from Pedro -

We knew that our LUSAT start transmitting again a couple of years ago, but
only when illuminated by sun, and was not heard during the night.

On the occasion of testing the application http://amsat.org.ar/sat.htm saw
there was a nightly pass, which was tried to listen.

Without much hope tuned 437.125 MHz, surprised to hear the usual strong
900mW continuous carrier +/- Doppler, but this time after 22 minutes of
being LUSAT in the dark.

Commenting locally, several other hams also tried and received LUSAT.

It's almost a miracle that after almost 25 years, LUSAT vintage Ni-Cd
batteries can receive and hold charge.

It seems LUSAT is willing to greet hams on his 'Silver Jubilee' due next
Jan-22 thru continuing talking with us from space after its more than
128,000 orbits.

The LO-19, next to Oscar-7 and UO-11 is one of the most long-lived active
amateur satellites.

We have included short report and audio on http://amsat.org.ar/?f=z ,
Amsat-LU logs.

More information on LUSAT (although in Spanish) on http://lusat.org.ar

Reports welcomed at info at amsat.org.ar

Last weekend, we had the ISS, SO-50, FO-29, AO-73, and AO-7 up and running. And although there were a couple 80-degree-plus passes of the new Chasqui-1 right over Southern CA, not a peep heard from it.

SO ... What are you going to work this weekend? Any projects or new birds in your plans?

Finally going to give it a try Saturday morning from DM03xs. Last weekend practiced tracking and receiving SO-50 on a couple of passes, one of them 86 deg up, passing almost straight overhead. Seems we started getting stuff only when it was 10 deg high or better, and lost it when it dropped below that. This was with an Elk 2m/440L5 and a Kenwood V7A.
Take heart knowing that your live hamfest demos weren't wasted!

THANK YOU for your kind words!

That 10:35AM PDT pass for So CA might be worked by a bunch of Scouts -
here's the pass, courtesy of PocketSat3:

Scout leader extraordinaire Tom N5HYP advises me he will attempt this pass tomorrow. As N5HYP.

NEXT Saturday the 13th at 10:45AM Central time he will have his Scouts and will be working SO-50 as K2BSA/5.

Sure.  I worked a really nice pass of AO-73 just a while ago using my FUNcube Dongle Pro + as the receiver and my Yaesu FT-857D as the transmitter.  While working stations, I was simultaneously decoding telemetry via the Dashboard application.



The above screenshot shows the beacon (strong red vertical bar) and two QSO's to the right of it in the transponder's pass band.



I captured 161 telemetry frames on this pass using my 7 element yagi, computer controlled for azimuth and elevation tracking.

There's a very nice SO-50 pass coming up at 7:23 UTC today, September 6.

The ISS is also sending SSTV and the packet digipeater is enabled.

From Jim G3WGM -

FUNcube/AO-73 is now in continuous transponder mode with low power
beacon, as at 09:32 UTC. Change back to Auto eclipse mode planned for
Sunday PM UTC.

Sorry its late this weekend (normally Friday evening). Please put this
down to operator error!!

Enjoy the transponder.

Amazing and wonderful results!

If you want to get a "taste" of playing with an SDR dongle - but do not want to spend US$204 for
the FUNcube Dongle Pro+ - try one of these for less than US$25 from Amazon ...

Absolutely the most fun I have derived from a $25 ham radio equipment-related purchase! There
is free software to use ... you might want to also pick up one of the suggested MCX antenna adapters
to easily improve the antenna.

No luck on SO50 today. We'll try again tomorrow, a good high pass happening.

CHECK YOUR SETTINGS! Although mobile, I heard comms on SO-50 this morning during the 10:35AM PDT pass over Rancho Cucamonga!

Better luck today.   Smiley

Thanks for the QSO on SO-50 just after 1100 PDT/1800 UTC this morning.  Good to finally work you on a satellite, after seeing you at the Yuma Hamfest for at least the last couple of years visiting the AMSAT booth.  Your signals sounded good through the satellite, and I will look up your e-mail address so I can send you an MP3 recording of the pass.  I will also prepare a QSL card with SASE, and get that in the mail tomorrow.

I also worked N7JY on that pass.  Any relation?

Thank you, we (my brother N7JY and I) got onto the satellite finally! Don't know what was wrong yesterday, we heard some stations but couldn't hear ourselves during the two times we tried, and heard no comeback.  Today went much better. I didn't hear much of my own audio on the downlink when transmitting, and I wonder if the 2m transmit through the same antenna was desensing the 70cm receive?  But thanks to you and KB6LTY for the audio files you both sent. I was surprised by how crisp my audio sounded there. This was with 5 watts.  I'll bring my QSL card to you in San Diego this coming weekend for the convention.
