I have for sale a Kenwood TS2000 HF/6m/2m/70cm satellite rig. This is the
model that does full duplex for the satellites, and does 100 watts on HF,
6m, and 2m, and 50 watts on 70cm. It has IF-DSP so you don't need any
optional filters and you also get noise reduction and an auto notch
filter. Has a built in TCXO, CW memory keyer, subreceiver that does AM/FM
on 2m and 70cm, and can also be used for Crossband repeat or Skycommand.
Also has a built in autotuner.
This is a 800xxxx serial number so it was produced before the bad filter
issue occurred with the TS2000. It comes with both original boxes, the
original manual, hand mic and power cord.
It is in very good condition with just a couple of very light scratches on
the case. I am asking $900 shipped in the US, and can take paypal/check/mo.

The nurse has given me limited clearance to go away on Labour Day
Weekend, so I will be making up my failed previous attempt to activate
FN27/28.
Friday and Monday will be travel days, and I'll spend Saturday and
Sunday on site. If the roads are no worse than I have encountered on
previous roves then I will attempt to activate FN37 as well. I also
plan to stop briefly for a few passes in FN26 on the way north on
Saturday morning around 1400 to 1500. Hopefully, not too early for
western and west coast operators.
I will spend Friday night in FN25 and Sunday night in FN24 on the way
home. I'll be on in the evenings from those grids.
My limited research shows that nobody has FN27/28/37. It ought to be a
busy weekend! Let's hope for good weather!
I'll post schedules as we get closer to departure day.

I added the PLOT of all the 46 APRS balloons on Eclipse day to my Balloon
page.
http://aprs.org/balloons.html
I assume these were trackers on all the 50 NASA balloons launched that day
by students all across the country to stream live video of the event. But
there is not a single mention of APRS on their web page, and not a single
Ham has mentioned involvement here on the APRSSIG or on AMSAT. Yet all the
balloons had Ham calls. I?d like someone involved to document the HAM
involvement in this massive undertaking and describe the APRS portion so I
can add it to the web page.
And why does FINDU.COM find about 148 Balloons in the USA, and I can only
count about 50 along the path and only a few more..?

ARISS Crossband Repeater is NOT Active for General Communications
ARISS reminds amateur operators that the voice repeater aboard the ISS
has not officially been activated for general radio contacts although
some stations have reported successful contacts using 435.050 MHz FM
as the uplink and 145.800 MHz FM as the downlink.
Last week these satellites with amateur radio were deployed by the
Russian crew during their EVA:
TOMSK TPU-120 (RS04S) 437.025 MHz FM voice announcements
Tanusha-SWSU-1 (RS-6S) 437.050 MHz AX25 9K6 bps, FM voice announcements
Tanusha-SWSU-2 (RS-7S) 437.050 MHz AX25 9K6 bps, FM voice announcements
The Russian team set up the ISS repeater as a crossband relay between
437.050 MHz and 145.800 MHz at the last minute because they were concerned
about getting telemetry from their satellites, which might be spinning
more than they had expected. They are hoping the nearby receiver on ISS
can capture and retransmit telemetry that is not being picked up on the
ground.
USING THE RADIO AS A VOICE REPEATER FOR GENERAL CONTACTS DOES INTERFERE
WITH THE INTENDED MISSION OF SUPPORTING RELAY OF TELEMETRY FROM THE TANUSHA
SATELLITES.
Radio amateurs wishing to try receiving the Tanusha telemetry can find
technical details on the Southwest State University Space Activity page
at: http://eng.swsu.ru/space
When the ARISS voice repeater is active and authorized for general amateur
voice contacts the uplink frequency is 437.800 MHz FM using the 145.800 MH
FM downlink.

CubeSat Launch Initiative Announcement of Opportunity
Accredited education institutions, nonprofit organizations, and
NASA centers can join the adventure and challenges of space while
helping the agency achieve its exploration goals through the next
round of the agency?s CubeSat Launch Initiative (CSLI).
Applicants must submit proposals by 4:30 p.m. EST, Nov. 21.
The CSLI provides CubeSat developers with a low-cost pathway to
conduct research in space that advances NASA's strategic goals
in the areas of science, exploration, technology development,
education and operations. The initiative allows students,
teachers and faculty to gain hands-on experience designing,
building, and operating these small research satellites.
To date, NASA has selected 151 CubeSat missions, 49 of which
have been launched into space. NASA has offered a launch
opportunity to 95 percent of those selected through previous
announcements, with 44 scheduled for launch within the next
12 months. The selected CubeSats represent participants from
38 states and 85 unique organizations across the country.
NASA will make selections by Feb. 16, 2018, and selection
does not guarantee a launch opportunity. Selected experiments
will be considered as auxiliary payloads on agency launches
or for deployment from the International Space Station
beginning in 2018 through 2021. U.S. non-pro?t and accredited
educational organizations are responsible for funding the
development of the small satellites.
For this round of the initiative, NASA is particularly interested
in participation from organizations in the District of Columbia,
Puerto Rico, and 12 states not previously selected. These states
are: Delaware, Kansas, Maine, Mississippi, Nebraska, Nevada, New
Hampshire, North Carolina, Oklahoma, South Carolina, South Dakota
and Wyoming.
CubeSats are part of a class of research spacecraft called
nanosatellites. CubeSats are built to standard dimensions of
10x10x11 centimeters, which are called units or U. They can be
1U, 2U, 3U, or 6U in size, and typically weigh less than 3 pounds
(1.33 kilograms) per U. A 6U CubeSat typically has a mass of
about 26.5 pounds (12 to 14 kilograms). The final mass of a
CubeSat depends on the selected deployment method.
Small satellites like CubeSats play a valuable role in the
agency?s exploration, technology, educational, and science
investigations, including planetary exploration, Earth observation,
and fundamental Earth and space science. They are a cornerstone in
the development of cutting-edge NASA technologies like laser
communications, satellite-to-satellite communications and
autonomous movement.

NASA Tournament Lab USSOCOM CubeSat Challenge
Do you have an idea that could advance the state of current CubeSat
technologies and payloads and demonstrate applications that may benefit any
of the USSOCOM missions? Propose new or innovative CubeSat payload
technology/use concepts that can be demonstrated to support USSOCOM missions
within 12-24 months. Seven $5,000 prizes will be awarded in the following
categories: 4 - 3U Winners, 2 - 6U Winners and 1 - People's Choice Award
Make sure to follow the competition to find out how you can get involved:
https://herox.com/cubesat-challenge
The United States Special Operations Command (USSOCOM) is the Unified
Combatant Command charged with manning, training, and equipping the various
Special Operations Component Commands of the Army, Marine Corps, Navy, and
Air Force of the United States Armed Forces. Core Activities within the
scope of Special Operations Forces (SOF) include: Direct Action, Special
Reconnaissance, Unconventional Warfare, Foreign Internal Defense, Civil
Affairs Operations, Counterterrorism, Military Information Support
Operations, Counter-proliferation of Weapons of Mass Destruction, Security
Force Assistance, Counterinsurgency, Hostage Rescue and Recovery, and
Foreign Humanitarian Assistance.
One of the guiding tenets of SOF is that most special operations require
non-SOF assistance. As such, USSOCOM is seeking global ideas on how to
advance CubeSat capabilities. Specifically, USSOCOM is conducting this
crowdsourcing challenge to solicit concepts that advance the state of
current CubeSat technologies and payloads and demonstrate applications that
may benefit any of the USSOCOM missions. Concepts should be viable for a
prototype demonstration within 12-24 months. These concepts will advance how
CubeSats can be utilized to support Special Operations Forces (SOF)
missions.
Example areas that are relevant to USSOCOM missions are (not an exhaustive
list):
+ Next-generation CubeSat and/or sensor technologies
+ Advanced communications; including full orbit Command & Control
and data exfiltration
+ Electro-Optical (EO)/Infrared (IR) sensing and imaging
+ Multi/Hyper spectral sensor technology
+ Propulsion capabilities to modify or maintain orbits
+ Advanced On-Orbit data processing
+ Multi-function payloads
+ Tagging, Tracking and Locating capabilities

Russian Arctic DXpedition Plan Includes Satellite Operation
Members of the Russian Robinson Club (RRC) continue planning for
their next Arctic operation. Look for RI1F to be active from
Victoriya Island (EU-190). They will will leave Murmansk sometime
late September (27th), and they are expected to operate between
October 1-7th. This island group has never been activated before.
By the way, these islands count for DXCC purposes as Franz Josef
Land. Activity will be on 160-10 meters, including the WARC bands,
VHF and UHF. Operations will be on CW, SSB, the Digital modes,
EME (dates are October 3-7th) and the satellites.
They plan to operate from two different sites (one HF and EME;
one VHF/UHF). The complete break down can be see on QRZ.com.
Currently, 12 operators have been named: Igor/UA9KDF (Team
leader), Yury/ UA9OBA (RRC President), Andrey/UA9LDD (CW op),

Hello fellow bird folk,
I noticed in the ANS today the specific note that the recent crossband
repeater activation was not to be used for general amateur communications.
With the popularity of this mode (and our current shortage of FM birds), has
there been any thought about making it a more common thing? It seems to be
wildly popular when it is active, and I'd like to think people would have
more respect for the times when it needs to be used for scientific functions
if it wasn't seen as just a really rare opportunity to make a QSO via the
repeater. Maybe there's a reason it's basically always off, just curious.

It?s basically always off for two reasons. First, we don?t have a
programmed radio that supports the mode. This experiment was being run on
an unprogrammed radio that the Russians sent up, not one of our standard
ARISS radios. Second, the stock D700 ARISS used in the past would overheat
in the high duty cycle repeater mode, because the stock fan doesn?t move
enough air to cool the radio in a zero-G environment.
But hope is in sight! The new Interoperable Radio System (IORS) that ARISS
is developing includes a TM-D710 specifically modified with repeater mode in
mind (along with some other things). We have a larger fan that should solve
the problem, and we expect the cross-band voice repeater to be a common
operating mode between school contacts, alternating with the digital
repeater and an occasional experimental mode.
The IORS had a final design review earlier this month, and a safety review
is coming in a few weeks (both reviews are with NASA engineers). All that
is left is to build and let NASA test our initial flight prototypes and then
build the final flight and training hardware. Oh, and raise enough money to
buy parts for the multi-voltage power supply that runs the radios.
ARISS encourages all hams that look forward to expanded ISS operations to
help by donating to the project. There is link for donations on the
AMSAT-NA website (www.amsat.org <http://www.amsat.org/>, click ?Donate? in
the menu bar).

With the popularity of this mode (and our current shortage of FM birds), has
there been any thought about making it a more common thing? It seems to be
wildly popular when it is active, and I'd like to think people would have
more respect for the times when it needs to be used for scientific functions
if it wasn't seen as just a really rare opportunity to make a QSO via the
repeater. Maybe there's a reason it's basically always off, just curious.

Subject: [amsat-bb] AO-85: Tone or no Tone for SSTV
Message-ID:

Content-Type: text/plain; charset="UTF-8"
two questions:
According to Amsat website, 67Hz tone is required for a couple of seconds
to activate repeater.
Once the repeater is activated, does it still require the tone every couple
of minutes to stay on, or does it only start the timer after normal
("un-toned") activity stops?
Will constantly sending the tone during SSTV Tx mess with the SSTV Rx?
I'm planning on eventually trying my own image, and want to be sure I don't
waste 36 seconds of valuable airtime.
