Hi!
I just uploaded my MP3 from the LilacSat-2 pass where I
worked Glenn AA5PK to my Dropbox space. The link to hear
the recording is:
https://db.tt/sPOYLsJF
I used my Icom IC-2820H and Elk log periodic to work
this pass, transmitting at 50W to get through the muck
on the 144.350 MHz uplink frequency. Once I found the
downlink, it was easier to hear than SO-50's downlink.

Hi Rick!
You should be ready for a downlink lower than what was
published. Glenn AA5PK and I were giving each other our
downlink frequencies late in the pass, so we could
compare where we were listening. If you didn't have more
than HT power (5W), you may have also had issues getting
through. Hopefully the FM transponder stays on, as these
lower passes compared to other satellites only leave me
one workable pass per late afternoon. If only these
satellites were launched 60 or 90 mimutes later...
As for the uplink frequency and where it falls in various
bandplans, Arizona - like the ARRL's 2m band plan - appears
to be the exception to the "rule" that nobody recognizes
anything more than 145.800-146.000 MHz for satellite
operation. I saw this page from the Amateur Radio Council
of Arizona, which is the coordinator in Arizona, for the
2m band plan:
<https://t.co/Y8DvZR8q3i>http://azfreqcoord.org/bp/144bp.html
Other than the APRS and AM calling/net frequencies, this is
one of the rare cases where amateur satellite operation is
actually recognized in a local band plan for this part of
the 2m band.
Since LilacSat-2, like most of the others launched over the
weekend, didn't receive IARU frequency coordination - it
won't be eligible for an OSCAR number. A shame, but I
understand the rationale for that. Just give a quick listen
on the 144.350 MHz frequency before transmitting, to make
sure you don't interfere with anyone else who might be
there, before working these passes. And be ready to adjust
the downlink quicker than you do with SO-50.
73!

Hi all,
Thank you very much for all the QSO reports via LilacSat-2! The repeater was
turned on at about 2230 UTC at 0.2W power. Not high but may hear good
because of our special antenna design :)
Due to some technical reasons, 437.200 is for TLM/FM/APRS and 437.225 is for
TLM. No 144.390 use any more.
Please check the radio info page for updated frequency table and more
information.

Patrick,
I saw the message about the FM transponder being on around the middle of the
pass, by the time I got my gear out and set up on the VFO (frequencies now
in memory) the bird was about 20 degree from LOS. Since I operate from the
backyard of my North facing house, it was down near the rooftops. I did
throw my call out, but did not hear the downlink. based on your report, I
was probably too high. I won't be available tomorrow or Thursday to try
again, maybe Friday. My Schedule is starting to ramp up with theater
season....
As for the choice of uplink, Here in AZ 144.410mhz has become the defacto Fm
simplex frequency for SOTA (Summits on the Air). So dredging up a discussion
from a few weeks back about the choice of frequency, It appears that the
IARU will not coordinate these frequencies, so does that mean these birds
will not receive OSCAR numbers?

Hi Glenn!
Thanks for the QSO on that pass, that started just after
0110 UTC. I was in a downpour in my back yard during the
last couple of minutes. Thankfully, thunder and lightning
stayed far enough away to be in the yard with my Elk. I
also heard KO6TZ and W7KKE, but they never returned calls
from either of us to make QSOs. I heard someone else near
the end of the pass, but I was having to shut down as I
tried to keep my radio from being swamped with rain. I went
with my Icom IC-2820H and Elk log periodic for this pass,
and I'm glad I did. HT power would not have been enough to
get through tonight, and that is a shame.
The uplink frequency appeared to be spot-on at 144.350 MHz.
Once I lined up the downlink, I didn't need to change my
uplink frequency, and did not have to go to narrow FM to
make it through the satellite. This frequency is an
unfortunate choice for an uplink, as it is not in a
recognized satellite subband in very many places. It is
in the "New OSCAR subband" according to the ARRL:
http://www.arrl.org/band-plan
Even though ARRL has specified 144.300-144.500 MHz as
another satellite subband, many parts of the US go in a
different direction for this part of the 2m band, never
mind other parts of the world. The IARU regional band
plans say nothing about amateur satellite operating
around 144.350 MHz. Here in Arizona, the ARRL-specified
144.300-144.500 MHz OSCAR subband is observed (with
exceptions for APRS on 144.390 MHz and AM on 144.450
MHz), but I know I have heard AM and SSB activity around
there in the past. In neighboring southern California,
the 144.300-144.500 MHz subband is for FM simplex, with
the exception of 144.390 MHz for APRS. In the southeastern
US where SERA is the frequency coordinator, this subband
is for "multi-mode operation", with APRS specified for
144.390 MHz. In any event, the international radio
regulations - and, for that matter, FCC Part 97 here in
the US - permit amateur satellite operations anywhere in
the 144-146 MHz range, and this is probably what was
being considered in China for this and the other
satellites recently launched.
The downlink appeared to be low, possibly as much as 15 to
25 kHz below the nominal frequency published before the
launch. When I shut down my gear, I was down to 437.190
MHz to hear the satellite. AA5PK said his radio was down
to 437.191 MHz at that point. My IC-2820H only tunes in 5
kHz steps, so I didn't have the finer tuning as Glenn had.
The downlink was strong, much stronger than SO-50. This
should be a big help for those who never heard satellites
like AO-27, AO-51, or HO-68 with the stronger downlinks
they had a few years back.
?For at least the last half of the pass, there was what
appeared to be a steady carrier on the 144.350 MHz uplink.
Glenn and I were able to overcome it, and - at least for
a moment or two - so were KO6TZ and W7KKE. W7KKE's audio
sounded a little on the low side, and I missed his call
in real time (Glenn didn't, and he called W7KKE without
success). I tried to overcome the carrier using the low
(5W) and mid (15W) power settings on my IC-2820H, and
those attempts failed. The high (50W) power setting? was
the only one I could use to get through. If I had to
rely on the memories in the radio to work this satellite,
I'd prepare many more memories with the downlink frequency
going down to 437.190 MHz and possibly even 437.185 MHz.
Be ready for anything, where you may even have to go
higher on the downlink frequency, but definitely be ready
for it to go way below the published 437.225 MHz frequency.
Weather permitting, I hope to be on another pass tomorrow
evening around the same time (0100 UTC, if my prediction is
correct). I can't work the pass before this one, between
the low elevation on that pass and I'll still be at the
office at that time.

Patrick,
A JA op posted a screen shot of LilacSat-2 on the AMSAT Facebook page, he
too was down around 437.191, so it does appear to be quite a bit lower. I
did notice the quick doppler change, especially near the zenith.
I'll give it a go on the D72a, if that proves unworkable, I'll set up the
Icom IC-7000 & HDSDR and see how that goes.
I'm currently working on a pair of Crossed Moxons so I don't have to lug
gear outside all the time. I'll add the AMSAT preamp, and hopefully that'll
hold me until I can afford the M2 Leo pack.
Not sure when I'll ahve the time, but now that it's cooling off, we need to
get together so you can elmer me on the fine art of working the linear
birds.

Good morning,
I just worked a pass of LilacSat-2 from here in Washington, DC. The
downlink signal was good and I was able to work KO4MA with 5 watts,
though the constant carrier and audio filtering made it tough to know
when I was getting in to the satellite. I had to listen very carefully
to hear my own voice coming back from my headphones. There was
terrestrial interference, but I was able to get in below 6 degrees and
heard the satellite all the way down to below a degree.
Equipment used was two Yaesu FT-817s, an Arrow antenna, and a High
Sierra Microwave LNAA432 preamp.

Fox Telemetry Decoder Software Version 1.0 Available for Download
Version 1.0 of the FoxTelem software, the Fox Telemetry Decoder is being
released to enable setup, testing, and debugging of your Fox-1A ground
station prior to the launch of the satellite. FoxTelem is used to
demodulate, store and analyze telemetry data from AMSAT?s Fox series of
Cube Sats.
Fox-1 satellites include two telemetry formats:
+ Slow Speed, also called Data Under Voice (DUV) is 200 bps FSK data
sent at the same time as the transponder audio. Whenever the trans-
mitter is on, data is being sent. This happens during beacons and
during live QSOs.
+ High Speed is 9600 bps FSK sent instead of the transponder. This is
used for data intensive experiments such as the Virginia Tech Camera.
This is only active when commanded from the ground. You can recognize
High Speed because it sounds like an old school computer modem.
FoxTelem will receive and store both formats assuming you can feed it audio
that does not have the frequencies below 200 Hz filtered. For High Speed,
the audio must also extend to include the full 9600bps bandwidth of the FM
signal. For both modes this is best achieved from a Software Defined Radio
or from the 9600 bps packet port of some radios. The FoxTelem User Guide
provides more details.
FoxTelem is supplied as an archive file (.zip on windows, .dmg file on
MacOs, .gzip on Linux). Links for downloading can be found at:
http://www.amsat.org/?page_id=4532
You can unzip the contents and put it in the directory of your choice.
Also, detailed in the User Guide, are instructions to select the sound
source and set received audio levels on your computer.
Until Fox-1A is launched you can confirm everything is working by testing
with test wav file which will be available from:
http://amsat.us/FoxTelem/recordings . Access to the test file is
accomplished by selecting ?Load Wav File? from the FoxTelem File menu, then
navigate to the directory where you saved the test wav file. Once you press
the start button the file will play through the decoder.
The FoxTelem page can also be accessed from the main AMSAT web page:
http://www.amsat.org --> Fox Project --> FoxTelem Software for Windows,
Mac, & Linux
The direct link to the page is: http://www.amsat.org/?page_id=4532
