I had a 75 degree pass of AO-7 this afternoon and thought I'd try to
hear the beacon. I've tried a couple of times now and not heard
anything. Maybe my high local noise level prevents me from hearing it,
but I don't have much noise with the antenna pointing almost straight
up.
Does the Mode B beacon on 145.975 MHz still function or has it failed?

But for the life of me, I can't think where we could find 70 megabytes
of ham radio content. Not useful content, anyway.

Ham radio CubeSat deployment postponed
The deployment of amateur radio CubeSats from the International
Space Station (ISS) planned for Thursday, February 6 has been
postponed.
NASA say:
Flight Engineer Koichi Wakata KC5ZTA spent his morning working in
the Japanese Kibo module to install a deployer mechanism that will be
used in concert with the Kibo robotic arm to "launch" the first set
of NanoRacks CubeSats. Wakata, who ran into some difficulty last week
installing an electronics box that would help control the deployment
of the mini-satellites, successfully installed that box after
troubleshooting an alignment issue. The deployment of the first
batch of CubeSats, which had originally been scheduled for this week
before being postponed following last week's installation issue, has
been postponed further to make sure that the CubeSats do not fall
into the intended orbit of the Global Precipitation Measurement
satellite launching later this month. The exact date of the CubeSat
deployment is still being evaluated.

Ham Video Commissioning postponed
ESA postponed the Ham Video Commissioning to March 8.
Possible dates for the four Commissioning steps are March 8 (step
1), March 9 (step 2), and March 16 (step 3).
Step 3 could be turned into step 4.
These dates are all on the weekend.
With this agenda, we have just 1 week of blank transmissions.
The agenda is still to be finalized.

Can Radio Hams receive NASA's ISSE-3/ICE ?
A post on the Planetary Society website wonders if radio amateurs
will be able to pick up the signal from the ISSE-3/ICE spacecraft as
it passes Earth
Emily Lakdawalla says: The International Sun-Earth Explorer (ISEE-
3), a spacecraft that was launched in 1978 to study Earth's
magnetosphere and repurposed in 1983 to study two comets. Renamed the
International Cometary Explorer (ICE), it has been in a heliocentric
orbit since then, traveling just slightly faster than Earth. It's
finally catching up to us from behind, and will return to Earth in
August, 2014.
It's still functioning, broadcasting a carrier signal that the Deep
Space Network successfully detected in 2008. Twelve of its 13
instruments were working when we last checked on its condition,
sometime prior to 1999.
The 36 year-old satellite is still apparently operational but it
appears that NASA can no longer send commands to it because the
transmitters to do so were removed in 1999.
Emily sums up:
So ISEE-3 will pass by us, ready to talk with us, but in the 30
years since it departed Earth we've lost the ability to speak its
language.
I wonder if ham radio operators will be able to pick up its carrier
signal - it's meaningless, I guess, but it feels like an honorable
thing to do, a kind of salute to the venerable ship as it passes by.
The satellite carries Redundant S-band transponders, each with 5
Watt RF output
Transponder A:
2090.66 MHz RHCP uplink, command or ranging
2270.40 MHz RHCP downlink, telemetry or ranging
Transponder B:
2041.95 MHz LHCP uplink, command
2217.50 MHz LHCP downlink, telemetry
Transmit antenna: medium gain with dual inputs for simultaneous
right and left hand circular polarization downlink, 8 rows of 4
elements, 7 dBi, ?6? beamwidth, multibeam, electronically steerable,
four lobe, omni directional coverage in azimuth
Receive antenna: 2042 MHz, intermediate gain, 1 row of 4 elements, 0

Send Your Name to the Asteroid Bennu!
NASA is inviting people around the world to submit their names to be
etched on a microchip aboard a spacecraft headed to the asteroid Bennu
in 2016.
The "Messages to Bennu!" microchip will travel to the asteroid aboard
the Origins Spectral Interpretation Resource Identification Security
Regolith Explorer, or OSIRIS-REx, spacecraft. The robotic mission will
spend more than two years at the asteroid, which has a width of
approximately 1,760 feet (500 meters). The spacecraft will collect a
sample of Bennu's surface and return it to Earth in a sample return
capsule.
The deadline to submit names online is Sept. 30, 2014. Participants
who submit their names to the "Messages to Bennu!" campaign will be
able to print a certificate of appreciation to document their
involvement.
For more information and to submit your name, visit
http://planetary.org/bennu.
Participants who "follow" or "like" the mission on Facebook
(https://www.facebook.com/OSIRISREx) will receive updates on the
location of their names in space from launch time until the asteroid
samples return to Earth in 2023. Facebook fans also will receive
mission progress and late-breaking news through regular status
updates.

Outernet - Shortwave radio from space
Outernet is described as the modern version of shortwave radio
broadcast from space
It is planned that the Outernet will consist of a constellation of
hundreds of low-cost, CubeSats in Low Earth Orbit (LEO). Each
satellite receives data streams from a network of ground stations and
transmits that data in a continuous loop until new content is
received.
In order to serve the widest possible global audience, the entire
constellation utilizes UDP-based multicasting over WiFi. Although
still not common, WiFi multicasting is a proven technology,
especially when the data requires only one hop to reach the recipient.
Outernet claims to be able to bypass censorship, ensure privacy, and
offer a universally-accessible information service at no cost to
global citizens.
They say lack of an Internet connection should not prevent anyone from
learning about current events, trending topics, and innovative ideas.
Although Outernet's near-term goal is to provide the entire world with
broadcast data, the long-term vision includes the addition of two-way
Internet access for everyone - for free.
The team hope to have the first test CubeSats launched in 2015.

FCC Seeks Comments on WR-2015 Draft Rcommendations
The FCC has invited comments by February 18 on the latest batch of
draft recommendations of its Advisory Committee for World
Radiocommunication Conference 2015 (WRC-2015).
At its January 27 meeting, the Advisory Committee (WAC) approved
draft recommendations on a number of issues that will be considered
by WRC-2015. Some items, including one which could possibly lead to
changes to 60 meters in the long term, could affect the Amateur and
Amateur-Satellite services.
Of interest to the Amateur Radio Satellite community, WRC-2015 will
consider a number of issues that could impact amateur allocations
above 420 MHz, including a possible extension of the current
worldwide allocation to the Earth Exploration-Satellite service in
the band 9300 to 9900 MHz by up to 600 MHz "within the frequency
bands 8700 to 9300 MHz and/or 9900 to 10,500 MHz"
Incumbent services in the 9900 to 10,500 MHz range include the
Radiolocation, Fixed, Mobile, Amateur, and Amateur-Satellite services.
The Amateur Service is secondary at 10,000 to 10,500 MHz worldwide,
and the Amateur-Satellite Service is secondary at 10,450 to 10,500
MHz worldwide.
The FCC said comments provided by interested parties will assist it
in its consultations with the US Department of State and NTIA in the
development of US positions for WRC-2015. "The recommendations...may
evolve in the course of interagency discussions as we approach WRC-15
and, therefore, do not constitute a final US Government position on
any issue," the FCC Public Notice stressed.
Comments should reference IB Docket 04-286 and specific
recommendations by WAC document number. Interested parties may file
comments via the FCC's Electronic Comment Filing System (ECFS) at
http://apps.fcc.gov/ecfs/ . The ARRL plans to file comments in this
proceeding.

This is primarily for the team getting ready for the Kicksat Sprite project
but I am posting it on the amsat -bb as well as there may be a science
teacher out there who may be interested.I'm not claiming it's revolutionary,
but timely.
The requirement is for an inexpensive antenna-head preamp, lightweight,
running on a battery.
I wouldn't claim it is a low noise preamp, but CATV ampifiers are available
for under ?5 including delivery from China.
I bought one in a car boot sale for a ?1. It was supposed to work on mains
electricty (220 volts!) and is therefore obviously unsuitable to use outside.
So I have taken out the mains transformer and the diode rectifier matrix and
now run it off a 9 volt battery. I've also shown that the input and output
sockets can be changed. This is simple soldering as even I can do it.
Obviously the same principle applies to any TV amplifier, broadband, and
needing filtering at the antenna head. Just look to see if 435 MHz is
included in the bandwidth.
At some point I'll design and construct an input filter.
For those who may be interested, here's a direct link to my page:
https://sites.google.com/site/andythomasorg/funcube/cheap-rf-amplifier
or you can get there by going to? http://www.andythomas.eu , choosing

A good example is the way some people stream live tracking data for all
satellites in view plus an update to the DX list of passes over the next 3
hours that is captured and displayed on all APRS radios in the local area.
The APRS radios capture this and display on the front panel the range and
bearing to the satellite, the uplink and downlink freqs and the Doppler.
Everything you needed to know to work the satellite while mobile in real
time.
In addition, if you have the voice module in the radio, the radio will
SPEAK the announcement of the satellite in view and will SPEAK the
elevation angle as "LOW or HIGH" every minute during the pass.
In addition, at any time during the day (or when you arrive in a parking
lot and just before you turn off the radio) one can hit the LIST button on
the radio and bring up the DX list and it will contain the next three hours
of pass times. (useful if there is one only 2 minutes away and worth
waiting for).
This way one never has to refer to a PC for tracking data, but simply watch
(or listen) for satellite alerts on your APRS radio. In fact it is ideal
to get alerts while you are in the mobile because that is also where you
can work em! There are many satellites that you can work from a mobile
with an FM rig, why not?
We have had this capability in all Kenwood and now Yaesu APRS radios going
back to 1998. You can see examples of the front panel displays on the APRS
HT on this web page http://aprs.org/localinfo.html about 90% down the page
under the paragraph heading LOCAL SATELLITE ALERTS.
And this is only a small part of the continuous streaming data on the APRS
channel (useful for the traveler). You also get the following data in real
time:
* FREQ, and TONE of locally recommended traveler Voice repeaters
(accessible with just a press of the TUNE or QSY button)
* FREQ, and TONE of nearby IRLP, Echolink or Allstar links
* TIMES and days of any local nets on these repeaters
* Times and dates of any local club meetings
*Announcements about upcoming HAMfests or events
* FREQ, location and distance to any other APRS mobile op in voice range
* Actual PING alerts if any other APRS mobile operator is in simplex range.
Too many people simply ignore APRS as a "tracking system" when it never was
intended that way. It was intended as a mobile data resource, pushing
relevant local content to the front panel about everything going on in HAM
radio in the local area for instant access. (And that includes satellites
in view) The APRS radios have over 900 pages of data memory that are being
refreshed constantly and are avaialble at any time. (Plus 10 pages of DX
list) Plus the data can be sorted for display by age, callsign, or
frquency, or distance.
See the above web page for all the content already available. But like
anything else in Ham radio, if no one is transmitting content in a local
area, then no one is even aware of this powerful Ham radio technique.
While traveling and just watching the data coming in from APRS, I have
stumbled into Hamfests, Pig roasts, club meetings and nets of all kinds to
just drop-in on along the road.
