Subject: [amsat-bb] LilacSat-2 FM Transponder
I have noticed that LilacSat-2's FM transponder has been on nearly
continuously for the past four days They may be keeping it active
continuously during the holiday period in China.
It's worth checking out if you haven't worked it yet. It's got a good signal
and can be easier to track than SO-50 because the carrier stays active for a
period when not receiving signals. The downlink antenna also uses circular
polarization, so there is less fading when using linear antennas than on
SO-50.
Uplink: 144.350 MHz FM (No PL)
Downlink: 437.200 MHz FM
Keep in mind that this uplink frequency is not within the normal
145.800 - 146.000 MHz satellite subband on two meters, though this frequency
is within the 144.300 - 144.500 MHz "New OSCAR subband" in the ARRL band
plan and is allocated to the Amateur Satellite Service (as is the entirety
of 144 - 146 MHz). On passes over the United States, quite a few packet
signals can be heard through the transponder.
If you use LoTW, the satellite name to use when uploading QSOs is 'CAS-3H.'

Just a quick note, if you have placed your booking or are about to
and... you have an American Express card, take a look at the AMEX
offers. Either in the Apple app (might also be on android) or on
Facebook. There is an offer, spend $250.00 in one transaction and get
$75 back. Offer looks like it runs from now through April 15. When they
have given back their allotment the offer will be deleted. The offer
does not appear on my wife's account so I made a $10 deposit towards our
total and maybe they will give her the offer.

Please join us in listening to the ISS contact with participants at the
Powys Secondary Schools, Mid Wales, UK, Saturday March 5th. AOS is
anticipated at 1053 UTC
The duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be a direct between NA1SS and GB4PCS in Wales. The contact is
expected to be conducted in English.
Audio from this contact will be fed into the:
EchoLink *AMSAT* (101377)
IRLP Node 9010 Discovery Reflector
Streaming Audio at: https://sites.google.com/site/arissaudio/
Watch the contact live at: https://principia.ariss.org/Live/
Audio on Echolink & web stream is generally transmitted around 20 minutes
prior to the contact taking place so that you can hear some of the
preparation that occurs. IRLP will begin just prior to the ground station
call to the ISS.
Please note that on Echolink there are automatic breaks of 1.5 seconds in
the audio transmission. These occur every 2.5 minutes during the event.
Breaks on IRLP are manual and occur approximately after every third
question.
** Contact times are approximate. If the ISS executes a reboost or other
manoeuvre, the AOS (Acquisition Of Signal) time may alter by a few minutes

You can see the bit rate here:

It is a 90kbps downlink with pre-determined content. (The speeds could
be increased if they paid more to the providers. The tuners are
capable of receiving much more)
An interesting idea was if this was on an amateur geostationary
satellite. The soon to be launched amateur one over Europe/Africa will
probably have a beacon or carrier, but what if that carried the
outernet data. The receiving dishes would need to be bigger (depending
on bit-rate error correction). That would instantly give 1/3 world
coverage with uplinking possible (uplink would need 10 watt 2300Mhz
amplifier) The uplink sharing could be controlled by the downlink. I
am not sure a HF return channel would scale,

I think this could be a problem with the regulations for Amateur Radio
in several countries. Outernet content is taken from Wikipedia, Youtube
and so on. Probably not something you can retransmit freely over Amateur
Radio. Also, doing this would probably be considered broadcasting, and
Amateurs aren't allowed to broadcast, other than for calling CQ and
beacons transmitting a limited amount of information.
However, Bob's idea may still be good for the Amateur geostationary
satellites. Retransmitting the whole APRS-IS traffic is probably OK with
the regulations. I'm wondering how much bandwidth would be required for
this.
EsHail'2 will be carrying a linear transponder, so in principle there is
nothing which prevents a ground station from retransmitting this kind of
traffic through the linear transponder, as long bandwidth is OK and if
this is considered a good use of the transponder (in principle, it is
designed for SSB and other narrowband modes).

Dani EA4GPZ.

It is part of a large geostationary satellite due to launch at the end of 2016
http://www.spacex.com/missions
https://spacexstats.com/missions/future
I assume at this stage all the equipment is more or less ready waiting
for the launch. It is listed on this page as late 2016:
Many European stations are getting ready to receive signals with a
slightly modified TV LNB, connected to around a 1m dish. Narrow band
uplink will probably need a 1m dish and a 10W amplifier on 2300Mhz.
Wideband DVB-S uplink is possible but I assume it would need a much
larger dish. There is a narrow band DVB-S format with reduced
bit-rate. I have lots of experience in this area.

APRS already has 3 LEO's in orbit and three more that are manifest. These
extend the APRS uplink capability to everywhere on Earth and the LIVE feed
from the satellites is available on http://ariss.net and
http://pcsat.findu.com and the live feed everywhere else is on
http://aprs.fi . So, in addition to all the HF IGates, and the VHF Igates
and the Satellite Igates, there is worldwide uplink potential (that is
"uplink" into the APRS network where then it gets parsed into the OUTERNET
uplink).
I am only talking about amateur radio content, nothing else meets our rules,
but as a 2-way emergency communications capability with more than 2 million
licensed amateur radio operators worldwide, it does have potential within
our rules. And it lets OUTERENET support a low cost 2-way global
communications at virtually no cost to them either.
> OUTERNET has three UHF cubesats that should be complete by May. [in
> addition to the GEO downlinks].
>> It is a 90kbps downlink with pre-determined content.
And we don't have to stream the entire APRS global feed! Only packets with
the PATH of "OUTNET" in them. So any ham, anywhere on earth, can route his
packet via the APRS satellite, or HF, or VHF terrestrial network and then
have it routed into the OUTERNET uplink by including "OUTNET" in his path,
and it will get sent on the OUTERNET uplink stream and hence to the OUTERNET
GEO downlink. Thus, a 2-way system for Amateur Radio and their Emergency
response.
The current APRS Satellite traffic is about 1000 packets per day and all are
visibile on the above TWO satellite feeds. That works out to about one
packet per minute or about 1 byte per second. 1 Baud would not be too much
to ask of OUTERNET. Of course, if they turn it on for us, then the rate
might increase TEN fold or in a few years, ONE HUDRED FOLD... To 100 baud.
Or even one THOUSAND fold and the bit rate would be up to only 1 kbps or
less than 1% of their traffic! Oh, and that is supporting thousands of
two-way amateur and emergtency communicators globally anywhere on earth!
