I am trying to get back into working Satellites again after a hiatus of
about 7 years. In trying to catch up, difficult to sort out the current
landscape of what can be worked. So a couple of probably dumb questions for
you guys who seem very much on top of the entire subject.
- So where or how can I get a complete list of all the Sats that are
currently workable with a full duplex FM HT setup?
- in reading about the new CAS 4A &4B, it says they have linear
transponders and it lists VHF and UHF frequencies for up & down-link. So is
linear transponder a code word for SSB, can't be worked using an HT?
- What exactly is a Linear Transponder?
Tnx & 73

Hi Paul,
The AMSAT website can provide a lot of the information thatyou need.
An overview the operational satellites can be found on the AMSAT Live
OSCAR Satellite Status Page(http://www.amsat.org/status/). There are
hyperlinks to additional information for many of the satellites listed
below the Name column on the left of the web page. Additional
information and links can be found on the Communication Satellites web
page (http://www.amsat.org/?page_id=177)
Essentially, a linear transponder receives signals at a specific center
frequency with a bandwidth of tens of kilohertz. It then retransmits them
at a different center frequency with the same bandwidth, sometimes inverting
the frequency band along the way. The frequency inversion helps to mitigate
the effects of Doppler shift. For example, CAS-4A receives at a center
frequency of 435.220 MHz with a bandwidth of 20 kHz. The signals are
retransmitted at a center frequency of 145.870 MHz and the frequency band
is inverted.
It is by agreement that the communication modes used to communicate through
the linear transponder satellites are CW (Morse code) and SSB. This is
done to conserve bandwidth usage and power utilization accorded to a
particular transmission. Theoretically, you could transmit FM, or any
other modulation, through a linear transponder, but you would become quite
unpopular for using up the bandwidth of the transponder with an
'unacceptable' signal. You can also become unpopular for transmitting too
strong a signal into the transponder, as your signal will be accorded most
of the power the transponder uses to transmit, thereby reducing the power
available for the other signals.
(On a soapbox for a moment: Given the proliferation of low power, narrow-
bandwidth digital modes that have become available, I'd think that there
should be some discussion about expanding beyond CW and SSB for use on
the linear transponder satellites. End of soapbox and queue up those who
disagree...)
Right now, there are effectively only two FM satellites: SO-50 and AO-85.
While Lilacsat-2 has an FM repeater, it is not always available. There
are a couple of FM satellites that should be launched this year, so the
outlook for FM birds will be better in the future. There are also APRS
digipeaters available of the ISS and NO-84, which you can communicate
with using a 2M FM handheld connected to a computer, tablet, or smart
phone. Some handhels have APRS capabilities built in.
I hope I've answered your questions sufficiently. Hope to hear you on the
FM satellites soon!
73,
Mac / AE5PH

Welcome back.
SO 50 and AO 85 are the current FM birds that are most usable. Lilacsat2
is workable but very very seldom is it turned on for reasons known only to
the Chinese folks that put it up.
You are correct about linear birds. Unless you can find an SSB capable HT
they are unworkable with an HT. Some folks have gotten brave and put cw
into it but that seems to be frowned upon.
CU on the birds!

Off topic, but we are getting close to launching QIKCOM-2 which will have a
DTMF uplink with APRS and voice downlink if the FCC would ever finish the
filing of the API submitted back in Nov 2014.
This will let simple HT's with only a DTMF keypad participate in APRS.and
two-way contacts.
http://aprs.org/qikcom-2.html
We are also delivering PSAT-2 which will have the same thing, but a better
voice module and a secondary payoload of a PSK31 transponder like is on
PSAT. Again, only if the FCC will finish processing the API that was
submitted back in 2015.
http://aprs.org/psat2.html
I hate to make such announcements until it is actually in space and
working, but Im working 12 hour days for months trying to finish and it is
working GREAT on the bench.
As some of you may remember, I have been an advocate of using DTMF for more
practical communications applications for years...since EVERYONE has an HT
that will do it. (except modern Baefengs - Needs a 16 digit DTMF memory to
be useful)

Additional info on FM satellites , IO-86 is also an FM bird (and also APRS),
but as this bird is on an equatorial orbit, it is not as well known, only
being used over part of India, Southeast Asia Countries and Brazil.
Several operators in Indonesia with HT and simple Superstik antenna have
successfully QSO thru the bird.
As a tertiary payload on LAPAN A2 satellite, the FM repeater module is
activated only once daily as also the APRS module. Additional activation of
FM module on weekends.
The full weekly schedule is posted on:
http://pusteksat.lapan.go.id/subblog/pages/2017/49/Jadwal-Operasi-Satelit-LAPA
N-A2LAPAN-ORARI
I'm heading to the US visiting family in Lubbock,TX and Portland, OR. If
anybody is interested I can present a talk on IO-86 Indonesia's first
amateur radio satellite.

2017 AMSAT Field Day Rules
It's that time of year again; summer and Field Day! Each year the
American Radio Relay League (ARRL) sponsors Field Day as a "picnic, a
campout, practice for emergencies, an informal contest and, most of
all, FUN!" The event takes place during a 24-hour period on the
fourth weekend of June. For 2017 the event takes place during a 27-
hour period from 1800 UTC on Saturday June 24, 2017 through 2100 UTC
on Sunday June 25, 2017. Those who set up prior to 1800 UTC on June
24 can operate only 24 hours. The Radio Amateur Satellite
Corporation (AMSAT) promotes its own version of Field Day for
operation via the amateur satellites, held concurrently with the ARRL
event.
This year should be easier than many years since we have about 10
transponders and repeaters available, with more possible before Field
Day. Users should check the AMSAT status page at
http://www.amsat.org/status/ and the pages at
http://www.amsat.org/?page_id=177 for what is available in the weeks
leading up to field day. To reduce the amount of time to research
each satellite, see the current FM satellite table at
http://www.amsat.org/?page_id=5012 and the current linear satellite
table at http://www.amsat.org/?page_id=5033
If you are considering ONLY the FM voice satellites like SO-50 for
your AMSAT Field Day focus, do not, unless you are simply hoping to
make one contact for the ARRL rules bonus points. The congestion on
FM LEO satellites is always so intense that we must continue to limit
their use to one-QSO-per-FM-satellite. This includes the
International Space Station. You will be allowed one QSO if the ISS
is operating Voice.
It was suggested during past field days that a control station be
allowed to coordinate contacts on the FM satellites. There is nothing
in the rules that would prohibit this. This is nothing more than a
single station working multiple QSO's. If a station were to act as a
control station and give QSO's to every other field day station, the
control station would still only be allowed to turn in one QSO per FM
satellite while the other station would be able to submit one QSO.
The format for the message exchange on the ISS or other digital
packet satellite is an unproto packet to the other station (3-way
exchange required) with all the same information as normally
exchanged for ARRL Field Day,
e.g.:
W6NWG de KK5DO 2A STX
KK5DO de W6NWG QSL 5A SDG
W6NWG de KK5DO QSL
If you have worked the satellites on Field Day in recent years, you
may have noticed a lot of good contacts can be made on some of the
less-populated, low-earth-orbit satellites like FO-29, AO-7, AO-73,
NAYIF-1 or the XW satellites. During Field Day the transponders come
alive like 20 meters on a weekend. The good news is that the
transponders on these satellites will support multiple simultaneous
contacts. The bad news is that you can't use FM, just low duty-cycle
modes like SSB and CW.
THE 2017 AMSAT FIELD DAY RULES
The AMSAT Field Day 2017 event is open to all Amateur Radio
operators. Amateurs are to use the exchange as specified in ARRL
rules for Field Day. The AMSAT competition is to encourage the use of
all amateur satellites, both analog and digital. Note that no points
will be credited for any contacts beyond the ONE allowed via each
single-channel FM satellite. Operators are encouraged not to make any
extra contacts via theses satellites (Ex: SO-50). CW contacts and
digital contacts are worth three points as outlined below.
1. Analog Transponders
ARRL rules apply, except:
- Each phone, CW, and digital segment ON EACH SATELLITE TRANSPONDER
is considered to be a separate band.
- CW and digital (RTTY, PSK-31, etc.) contacts count THREE points
each.
- Stations may only count one (1) completed QSO on any single
channel FM satellite. If a satellite has multiple modes such as V/u
and L/s modes both turned on, one contact each is allowed. If the
PBBS is on - see Pacsats below, ISS (1 phone and 1 digital),
Contacts with the ISS crew will count for one contact if they are
active. PCSat (I, II, etc.) (1 digital),
- The use of more than one transmitter at the same time on a single
satellite transponder is prohibited.
2. Digital Transponders
We have only APRS digipeaters and 10m to 70cm PSK transponders (see
Bob Bruninga's article in the March/April, 2016 issue of the AMSAT
Journal).
Satellite digipeat QSO's and APRS short-message contacts are worth
three points each, but must be complete verified two-way exchanges.
The one contact per FM satellite is not applied to digital
transponders.
The use of terrestrial gateway stations or internet gateways (i.e.
EchoLink, IRLP, etc.) to uplink/downlink is not allowed.
Sample Satellite Field Day Greetings File:
Greetings from W5MSQ Field Day Satellite station near Katy, Texas,
EL-29, with 20 participants, operating class 2A, in the AMSAT-Houston
group with the Houston Amateur Television Society and the Houston QRP
club. All the best and 73!
Note that the message stated the call, name of the group, operating
class, where they were located (the grid square would be helpful) and
how many operators were in attendance.
3. Operating Class
Stations operating portable and using emergency power (as per ARRL
Field Day rules) are in a separate operating class from those at home
connected to commercial power. On the report form simply check off
Emergency or Commercial for the Power Source and be sure to specify
your ARRL operating class (2A, 1C, etc.).
AND FINALLY...
The Satellite Summary Sheet should be used for submission of the
AMSAT Field Day competition and be received by KK5DO (email or postal
mail) by 11:59 P.M. CDT, Monday, July 10, 2017. This is earlier than
the due date for the ARRL submissions. The preferred method for
submitting your log is via e-mail to kk5do at amsat dot org or
kk5do at arrl dot net.
You may also use the postal service but give plenty of time for your
results to arrive by the submission date. Add photographs or other
interesting information that can be used in an article for the
Journal.
You will receive an email back (within one or two days) from me when
I receive your email submission. If you do not receive a confirmation
message, then I have not received your submission. Try sending it
again or send it to my other email address.

Certificates will be awarded for the first-place emergency
power/portable station at the AMSAT General Meeting and Space
Symposium in the fall of 2017. Certificates will also be awarded to
the second and third place portable/emergency operation in addition
to the first-place home station running on emergency power. A station
submitting high, award-winning scores will be requested to send in
dupe sheets for analog contacts and message listings for digital
downloads.
You may have multiple rig difficulties, antenna failures, computer
glitches, generator disasters, tropical storms, and there may even be
satellite problems, but the goal is to test your ability to operate
in an emergency situation. Try different gear. Demonstrate
satellite operations to hams that don't even know the HAMSATS exist.
Test your equipment. Avoid making more than ONE contact via the FM-
only voice HAMSATS or the ISS, and enjoy the event!

Iceland/Greenland/Faroe Islands on Satellite July 4-19
Gabe Zeifman NJ7H/VE6NJH has finalized plans for an upcoming trip to
Iceland, Greenland, and the Faroe Islands. Once again, this is a trip
with family so radio is not his priority. However, he will put forth
my best effort to give these rare entities and associated grids to
everyone in range.
Gabe will be arriving in Iceland at about 0000Z on July 5 and spend
one night
at the hotel on the airport (access to HP83/84 line).
Gabe reports, "We will be in Iceland until July 10 with numerous
grids in the HP and IP fields possible, no strict plan yet.
"We will continue on to the Faroe Islands July 10-14. I will make an
effort to operate from both IP61 and IP62 while in the Faroes.
"Finally, we will head to Greenland on July 14th staying until the
18th. The destination in Greenland is Ilulissat in GP49. I do not
anticipate any other grids to be activated in Greenland, although if
there is an opportunity I will, but I don't expect any opportunities.
>From GP49 all of North/Central America and Europe should be in range,
along with portions of South America, Asia, and Africa, much of it
even possible on SO-50. I anticipate a nearly perfect horizon to the
west.
"On the 19th we travel back to the US with a several hour connection
in Iceland. I will also have two nights on the beginning and end in
New York City, and July 21-25 in Florida (anyone who needs EM90, hit
me up).
"In exciting news, this very well may be the last DX use of NJ7H.
Don't worry, I am not retired from roving. I am beginning my training
at the FAA as an air traffic controller on July 26th and will be very
busy with that. I expect facility placement in late October, and I am
requesting Alaska. Although I cannot yet be certain, I have been told
that I should expect to receive my request.
"QSLing for this trip will be via LoTW. I still need to get some new
generic cards printed, but if you need paper I'll get cards printed
eventually, just don't expect rush service (I have some from other
trips in the backlog, don't worry I havn't forgotten)."
Calls to be used:
Iceland: TF/NJ7H
Greenland: OX/NJ7H
Faroe Islands: OY/NJ7H

Wireless Institute of Australia reports amateur radio rescue of
satellite
I-Inspire-2 is a 20 x 10 x 10cm CubeSat built by the University of
Sydney in collaboration with the Australian National University and
the University of New South Wales (Sydney). On board the tiny
spacecraft is an experiment, part of the European QB50 project,
designed to ?explore the lower thermosphere, for re-entry research
and in-orbit demonstration of technologies and miniaturised sensors?,
as reported in earlier editions of the WIA broadcast.
Its operational frequency was coordinated by IARU to be in the
satellite segment of the 70cm amateur band.
It was placed in orbit from the International Space Station in late
May. The deployment was successful; however there were no signs of
life when the ground stations started looking for it. The engineering
group quickly tested various scenarios on the engineering model only
to come to the conclusion that, due to the extended delay in the
deployment, the satellite's battery was likely to be depleted and the
satellite was trapped in an endless loop, trying to deploy its antenna.
The engineering group suggested that the satellite is still
listening albeit with its antennas in the stowed position. This meant
that the satellite command receiver might have difficulty receiving
any signals from ground control stations. A set of commands were
devised which, if received, would instruct the satellite to wait
until the battery is charged before attempting to deploy its antenna.
Both UNSW and ANU ground stations transmitted the recovery command to
the satellite; however after a week or so of no success it was
decided that more transmitter power was required to overcome the lack
of receiver sensitivity caused by the still stowed antenna. A request
for assistance was passed to EME operators around the world and many
responses were received.
The greatest hope for a successful recovery was thought to be PI 9
CAM using high power and a 25 m dish, normally used for radio
astronomy but also EME. They were scheduled to transmit on the
weekend of the 10th and 11th of June.
On Sunday the 11th of June, during the morning pass, Rob VK1KW
reported a strong signal every 30 seconds on I-Inspire-2's frequency.
Dimitris VK1SV who is part of the ANU team, verified reception from
home around midnight. The following morning Dimitris drove to the ANU
ground station and was able to send commands to the satellite for the
first time since it was deployed. Many other radio amateurs around
the world also reported reception of the beacon. The satellite had
come back to life!
This is a wonderful example of successful collaboration between
radio amateurs and the academic community. If a frequency outside the
radio amateur band had been used, it is doubtful that the satellite
would have been brought back to life.
The crew of I-Inspire-2 wishes to thank all radio amateurs involved
and is looking forward to a successful collection of data for the
scientific experiment!
