Hi!
Earlier today, I tweeted a quick comment about what I saw on
the ISS 145.825 MHz digipeater just after 1900 UTC this
afternoon. Since tweets are limited in length, I'm posting a
longer message here...
In the past few weeks, once word got out that a replacement for
the failed Ericsson VHF HT on the ISS was being sent up to the
station, many were anxiously looking forward to seeing the ISS
digipeater move from 437.550 MHz back to 145.825 MHz, where it
had been until the old radio's failure in mid-October 2016. I
understood that many would welcome this change, but I was not
jumping up and down with excitement. Unfortunately, after
seeing the activity on the ISS digipeater in the past day or so
since the replacement VHF radio was put on 145.825 MHz, my
worries have been confirmed.
For many, the move to 437.550 MHz meant many stations that could
easily work 145.825 MHz would have to change. Whether it was a
different antenna for the 70cm band or dealing with Doppler with
the 437.550 MHz frequency, almost all of the unattended stations
that had been present on the 145.825 MHz frequency were gone. If
you wanted to use the ISS digipeater to work other stations, this
was a great opportunity. Many stations using APRS-ready HTs and
mobile transceivers were showing up, using a group of memory
channels to compensate for Doppler, and were making contacts. Some
fixed stations, including those already capable of satellite
operating, were also showing up. Even on the busier passes, the
437.550 MHz always seemed to be clear of the clutter from the
unattended stations that previously inhabited 145.825 MHz.
Fast forward to yesterday (Friday, 14 April). The ISS digipeater
switched to 145.825 MHz in time for afternoon/evening passes over
Europe (around 1330-1400 UTC). Lots of stations showed up, based
on looking at the ariss.net web site. The same thing started to
happen here in North America, later in the day. The passes I worked
last night were not bad, but there were more stations on one pass
that went over much of the continental USA than I'd typically see
on 437.550 MHz.
By midday today (1900 UTC), it seemed like many more stations were
on the frequency. I saw 11 other call signs on a pass just after
that time this afternoon. At best, there may have been 4 or 5 other
operators at their keyboards or keypads, looking to make contacts.
The others were just squawking away, not answering APRS messages
sent to them. By the time the ISS footprint was reaching the east
coast, the frequency was congested. Lots of position beacons were
coming through, but not much of anything else. This is not new;
Clayton W5PFG wrote about this about a year ago, here on the
AMSAT-BB list:
http://amsat.org/pipermail/amsat-bb/2016-April/058200.html
For the two passes I worked this afternoon, around 1900 and 2035
UTC, I made two QSOs on the earlier pass, and one on the later
pass. A shame, considering there were so many other call signs
on the earlier pass, and even some rare spots - stations in DM44
in northern Arizona and CM86 in Santa Cruz CA were seen.
It is interesting that hams want to have their stations squawk on
145.825 MHz when nobody is at the keyboard. It could be doing it
24/7, no matter if the ISS is in view or not. Would anyone
think of setting up their satellite station to automatically
transmit their call sign and location every 15/30/60 seconds to
SO-50, unattended? I think not! That could be a violation of
the regulations, and would definitely be poor form by that operator.
Bob Bruninga WB4APR has a couple of documents with recommendations
for beacon intervals when working the ISS digipeater. One mentioned
a 5-minute interval for unattended stations:
http://www.aprs.org/iss-aprs/iss-tx.txt
Another document recommends that unattended stations should be in
"receive ONLY mode." (emphasis is Bob's):
http://www.aprs.org/iss-aprs/utiquet.txt
I agree with the latter. If your station is unattended, why have
it transmit at all?! It may be different for less-populated parts
of the world, where gateway stations may transmit and then receive
their beacons from the ISS, which will show up on ariss.net and
other sites. For Europe, and definitely North America, the gateways
really don't need to transmit if they are unattended. There should
be activity on most passes, maybe even late into the night, to
know 145.825 MHz on the ISS is up and running.
Please don't misunderstand me... I think it is great for hams to
set up gateway stations listening on 145.825 MHz for the space-borne
APRS activity (ISS, NO-84, even NO-44 when it gets enough power to
transmit complete packets). But these stations, like other stations
that aren't operating as gateways yet transmit automatically,
shouldn't contribute to the congestion on the frequency.
I know I am in the minority on the ISS digipeater moving back to
145.825 MHz. Between the unattended stations clogging up the
frequency and some local interference I hear on 145.825 MHz around
my house, having the ISS on 437.550 MHz was fun! I worked it from
home, and on some of my road trips in the past 5+ months. Even for
some of my last NPOTA activations at the end of 2016. I'll continue
to work the ISS digipeater, almost exclusively with my APRS-ready
HTs (TH-D72A, or TH-D74A), looking to make QSOs by exchanging APRS
messages with other stations. If you can work packet from your
station, and we are in the same footprints, I hope to hear you (and
see you on my screen) soon. Like W5PFG mentioned a year ago, let's
get more stations on 145.825 MHz making QSOs...
73!

The RARSfest satellite demos today were a success, despite some
difficulties. In all we made 17 contacts across one SO-50 pass and one
FO-29 pass.
You can see a few pictures of the demos here:
http://imgur.com/a/uMOF4
I had trouble getting into SO-50, and Tucker, W4FS, had trouble
hearing FO-29. After reviewing a video I made of the SO-50 pass, I
realized I wasn't aiming the antenna in the right direction for the
first half of the pass. I had a hard time tracking it as the location
we chose which was the easiest for attendees to find was also right
next to the building the hamfest was in, and SO-50 rose right behind
it. By the time I heard the bird around 20 or 30 degrees elevation, I
wasn't aiming quite right, so every time I tried to get in I got very
intermittent audio at best. After one complete transmission, Jeff,
WB8RJY, came back to me and said hi to the hamfest and everyone
clapped. Unfortunately I wasn't able to complete the QSO. At max
elevation I knew exactly where to aim and called him back and
completed the QSO. Towards the end of the pass when the bird was
further north and less people were in its footprint I made a string of
contacts adding up to eight in total.
As for FO-29, Tucker was getting S9 noise during the first half of the
pass and could barely hear any signals. I experienced the same
interference yesterday when I did some practice passes. It's something
local we can't control. It was so bad Tucker actually turned off the
radio halfway into the pass and apologized to everyone that he wasn't
going to be able to complete the demo. Not long after this he noticed
a text message from a friend listening to him on the downlink saying
he sounded fine. So he turned the radio back on and this time there
was no noise because all we heard were very clear voices. After he
found himself on the downlink and made one CQ, Clayton, W5PFG, came
right back to him. And the crowd cheered when Clayton referenced the
hamfest and said he was from Texas. After that Tucker had a mini
pileup and made eight more contacts adding up to nine in total.
It looks like I had a crowd in the high 20s and Tucker had a larger
crowd in the low 30s. I was pleasantly surprised we were able to get
such a good turnout considering this was added to the hamfest at the
last minute.
Thanks to all of the operators who worked us! And to anyone that
called us who we couldn't get back to, like Paul, N8HM, thanks for
trying and sorry we couldn't make contact.

Hi Patrick,
Thanks for your post and feedback. It is much appreciated.
I am too looking once in a while for an ISS contact. On the other hand, I
have realized that many stations are actually on the keyboard and they
answer, but I don't decode it on my system and they might not either. I see
it later on the web. In addition, folks are not that quick in response also
and trying to type an answer and get a packet out especially on a less
elaborate station is not always easy. Yes, I am using UISS with
pre-recorded answers and a quick mouse click but I still need a few tries
to sometimes see or hear my own packet repeated. So, bottom line for me, be
happy for the few contacts and help others along :-)
73, Stefan, VE4NSA

Packet From The International Space Station Is Back On 145.825 MHz
The ARISS Team (Amateur Radio on the International Space Station) is
pleased to announce that packet from the International Space Station
(ISS) is once again on 145.825 MHz! ARISS did the foot work and
paperwork a few months ago to launch the last back-up Ericsson VHF
handheld radio to the ISS. This work was begun in October after the
failure of the Ericsson unit that had been used on the ISS. The
Ericssons have been operating on the ARISS for 16 years. In the last
days of February, the SpaceX 10 launch vehicle, Dragon, flew to the
ISS with the HT onboard. After the docking, ISS crew members had the
odious job of unloading and unpacking 5,500 pounds of cargo,
including the Ericsson HT.
ARISS got word Friday morning that we now have VHF capability back in
the Columbus module. Followers of ISS Fan Club have already posted
that they've heard and used VHF packet, and are thrilled and happy to
have it again!
In 2015, ARISS began its first fundraising campaigns. ARISS relies
on NASA, ARRL, AMSAT and many fine individual donors, along with
ARISS volunteers, to maintain the day-to-day operations and cover
those expenses along with all costs and work related to the hardware,
and building a new radio system, including the expensive space
certification tests. Donors can go to www.amsat.org and
www.ariss.org to support the program that excites hams and young
people and educators who are inspired by amateur radio on the ISS.
About ARISS
Amateur Radio on the International Space Station (ARISS) is a
cooperative venture of international amateur radio societies and the
space agencies that support the International Space Station (ISS). In
the United States, sponsors are the Radio Amateur Satellite
Corporation (AMSAT), the American Radio Relay League (ARRL), the
Center for the Advancement of Science in Space (CASIS) and National
Aeronautics and Space Administration (NASA). The primary goal of
ARISS is to promote exploration of science, technology, engineering,
and mathematics (STEM) topics by organizing scheduled contacts via
amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of
experienced amateur radio volunteers, ISS crews speak directly with
large audiences in a variety of public forums. Before and during

AMSAT at the Dayton Hamvention -- Call for volunteers
Last year, we had about 50 people assist with the AMSAT booth at the
Hamvention. It was the efforts of those volunteers that made the 2016
Dayton Hamvention a success for AMSAT.
The interaction with AMSAT members, satellite operators, designers,
and builders makes the whole experience a lot of fun.
The 2016 Hamvention is May 19-21 in a new venue: the Greene County
Fairgrounds in Xenia, Ohio. Would you consider helping AMSAT at the
Hamvention this year?
Whether you're available for only a couple of hours or if you can
spend the entire weekend with us, your help would be greatly
appreciated.
Please send an e-mail to Steve, n9ip at amsat.org if you can help.

Australian university students to launch satellite in 2018
Students at the University of Melbourne are well advanced on a
program to build a nano-satellite, with the Wireless Institute of
Australia assisting in the IARU frequency and other coordination
processes.
Through the Melbourne Space Program (MSP) affiliated with the
University of Melbourne, all is moving ahead for a hand-over of the
nano-satellite in November and a launch as early as January 2018.
Funding comes from the University of Melbourne, while the Melbourne
Space Program is an organisation that holds the licensing, and other
matters related to the launch.
In a media release, the MSP revealed that plans are well under way
with rideshare provider SpaceFlight with a contract signed for a
November hand-off and its launch as early as January 2018. It has
involved a group of ambitious students, seeking to understand and
help redefine the Australian space sector through innovation in
education, economics and policy, as well as engineering.
Australia is the only Organisation for Economic Cooperation and
Development (OECD) nation without a space agency. In 1966, University
of Melbourne students built Australia's first satellite that was
launched in 1970 as Australis Oscar 5 to be tracked by 200 radio
amateurs in 27 different countries.
The Melbourne Space Program has about 70 active members who are
students ranging from 1st year university to masters level and post-
graduate.
The key objectives include being the first students to launch an
Australian nano-satellite, create education, research in space,
collaborate with academia and industry, and promote gender parity in
the STEM (science, technology, engineering and mathematics) and Arts
disciplines.
Work was continuing to launch Australia's first nano-satellite and
more news is expected in coming months.
(Fred Swainston VK3DAC/VK4FE, WIA STEM Coordinator)
Aussies tracking satellite
Students of the FH Aachen University of Applied Sciences in Germany
will launch the COMPASS 2 cube-sat in May and are at looking for a
possible ground station partner in Australia.
WIA Director Fred Swainston VK3DAC/VK4FE, WIA STEM Coordinator says
the International Space Station Crew Fund Scholarship winner for
2017, Ian Benecken has asked the Wireless Institute of Australia for
help to track it.
COMPASS 2 is to be launched from a Polar Satellite Launch Vehicle by
the Indian Space Research Organisation carrying other commercial
satellites.
>From a polar 600 kilometre high orbit the cube-sat will beacon once
a minute the callsign of ON04DL (ON zero four DL) on 437.300 MHz.
The unique location of Australia makes it ideal for partner ground
stations, and already it has piqued an interest from the ARISS
telebridge centres on VK4, VK5 and VK6.
Soon to be published is software that anyone can use to decode the
beacon signal and the launch is likely to be on the 1st or 2nd week
of May.

Hi Stefan!
I also look online after the passes, hoping to see gateways picking up
the activity. Looks like some of the gateways either need to be turned
on again, or switched back to 145.825 MHz.
Seems like there are a lot of stations using UISS, which makes the
use of APRS messages an easy thing. Several of the calls I saw on
the radio today were the same calls that never responded to APRS
messages in the past. More often than not, if the station is using
an HT, or maybe a mobile radio (as identified on the screen when I
see details on that station on my screen), those are the stations
I have the best chance at making a QSO.
Maybe some of these stations won't stay on 145.825 MHz, after the
novelty of the ISS digipeater coming back to 2m wears off. If there are
operators at those keyboards, hopefully they will answer the APRS
messages they receive from me and others, and try to contact stations
they see/hear on these passes.
Hopefully we can make a QSO over the ISS digipeater on 2m soon! 73!
