Clive,
Thank you for sending this out - this may answer something I was wondering
about a few weeks ago....
I was out during a morning 1300-1400z HO68 pass about 3-4 weeks ago, and
as
I was doing the pass, I noticed the S-meter on my TRANSMIT HT was peaking
at
about S7 (I was using one HT to receive the 435.675 downlink, and the
other
for the 145.825 uplink). I turned the volume up on the transmit HT to see
what it was, and I heard the EXACT same audio that you have on your
webpage
of Oscar-11's telemetry beacon on 145.826 (1 kHz off of the uplink for
HO68). I am assuming that what I heard on my transmit HT was probably the
Oscar-11 beacon - could anyone confirm that?
73,
Zack

Subject: [amsat-bb] OSCAR-11 Report
OSCAR-11 REPORT 30 September 2010
This report covers the period from 30 March to 30 September
2010. During this time the satellite was silent until it was
heard by JA0CAW on 29 August. Since then, it was heard until
08 September and from 18 to 29 September. Excellent signals
have been reported from stations located around the world,
and good copy obtained from decoded telemetry frames.
There has been a significant change since the previous
period of activity which ended in March 2010. The on-board
clock is now very stable. It's gained only three seconds in
30 days. This is comparable with its accuracy when the
satellite was fully operational. During its first 21 years
it gained approximately one minute per year. However, there
is still an accumulated loss of 309 days, which has occurred
during eclipses of the last few years.!
The other change is that it's now transmitting during
eclipses, although signals are weaker at those times. This
indicates that there is still some capacity remaining in the
battery.
These two changes suggest that some part of the system may
have recently failed 'open circuit' thus reducing the
overall power drain of the system, and allowing more power
to be available during eclipses. There was an unexplained
current drain observed when analogue telemetry was last
transmitted. This fault might have cleared. Interestingly,
the status telemetry shows that the Digital Store & Readout
experiment has switched off, since the satellite was
previously heard in February.
The satellite appears to be operating for ten days on,
followed by ten days off, so it should start transmitting
again around 09 October.
The Beacon frequencies are -
VHF 145.826 MHz. AFSK FM ASCII Telemetry
UHF 435.025 MHz. OFF
S-band 2401.5 MHz. OFF
Reception reports have been received from Bernard FY1LE,
Roland DG1EBR, Mike DK3WN, Tetsu JA0CAW, Adam SQ8MFC,
MM0DNX, Tony VK3KKP/G8HIM, Martin DC1MAR, John M0BIC,
Etienne F1GRR and Carlos KD6GRF. Many thanks to everyone.
Many reports have also been added to the live satellite
status page, on the website set up by David KD5QGR and Bob
WB4APR. This is a very convenient and easy to use facility,
which shows the current status of all the amateur
satellites. Strongly recommended for future reports! The
URL is http://oscar.dcarr.org/index.php
For the benefit of new listeners, here is a short history
of OSCAR-11. It was lauched in 1984, providing telemetry
and other digital services for amateur radio and educational
users. During its many years of operation it survived long
periods of eclipses and continuous full sunlight.
In 2002 the satellite reverted to its default mode of
operation, controlled by the watchdog timer. In 2005 all the
analogue telemetry channels failed. Solar eclipses also
started to cause the watchdog timer cycle to reset, which
switched off the satellite for approximately 15 days.
In 2008 solar eclipses became a permanent feature of every
orbit, causing the satellite to switch off for about 15
days, probably after only one orbit of transmission. Thus
the satellite was not expected to be heard again for any
continuous period until 2019, when there will be some
eclipse free periods. However, the satellite started
transmissions unexpectedly in November 2008. These continued
until March, when it was followed by silence until until the
recent period of activity.
OSCAR-11 transmits on 145.826 MHz., set receiver to NBFM.
The satellite has a characteristic sound, rather like raspy
slow morse code, sending "di di dah dah dah dah dah dah dah"
sent over a period of five seconds. If you are receiving a
very weak signal, switch the receiver to CW or SSB. You
should hear several sidebands around the carrier frequency
and should be able to hear the characteristic 'morse code
like' sound on at least one sideband.
Please note that you need a clean noise-free signal to
decode the signals, and your receiver must be set to NBFM
mode, for a decoder to work.
If you need to know what OSCAR-11 sounds like, there is an
audio clip on my website www.g3cwv.co.uk/ which may be
useful for identification and as a test signal for decoding.
The current status of the satellite, is that all the
analogue telemetry channels, 0 to 59 are zero, ie they have
failed. The status channels 60 to 67 are still working. The
real time clock is showing a large accumulated error, but is
now incrementing accurately to within a few seconds per
month. The day of the month has a bit stuck at 'one' so the
day of the month may show an error of +40 days for some
dates. The time display has switched into 12 hour mode.
Unfortunately, there is no AM/PM indicator, since the time
display format was designed for 24 hour mode.
The spacecraft computer and active attitude control system
have switched OFF, ie. the satellite' attitude is controlled
only by the passive gravity boom gradient, and the satellite
is free to spin at any speed.
The watchdog timer now operates on a 20 day cycle. The
ON/OFF times have tended to be very consistent. The average
of many observations have shown this to be 20.7 days, ie.
10.3 day s ON followed by 10.4 days OFF.
Listeners to OSCAR-11 may be interested in visiting my
website. If you need to know what OSCAR-11 should sound
like, there is a short audio clip for you to hear. The last
telemetry received from the satellite is available for
download. The website contains an archive of news &
telemetry data which is updated from time to time. It also
contains details about using a soundcard or hardware
demodulators for data capture. There is software for
capturing data, and decoding ASCII telemetry. The URL is
www.g3cwv.co.uk .

Almost certainly. I've heard it several times, including last Monday
while I was out mobile. Around 11am local, it was loud even going
through the Charing Cross cutting in the middle of Glasgow - obviously I
couldn't hear it while I was in the tunnel section - and remained so for
a good five minutes. When I was out in the clear away from buildings it
was a solid fully-quieting signal.
Has anyone decoded anything off it yet?

Message-ID: <181341.61326.qm@xxxxxxxx.xxxx.xxx.xxxxx.xxx>
Content-Type: text/plain; charset=utf-8
At the (British) National Hamfest yesterday I had a play with the
pre-production model of the THD-72E and asked about full duplex.
I couldn't get into full duplex on the menu and had to give the set back
but I insisted onthe question in the name of AMSAT and they went to the
manuals while some other guys played with it.
On the second manual(printed off the cdrom) - which they said was about
the packet function - there was the following instruction:
"FULL DUPLEX
Ths transceiver is also capable of simultaneously transmitting and
receiving signals. So it is possible to transmit audio on the current band
while receiving packet data on the other band (data band).
1 Set operation band to band B
2.Press [F DUP] to enter Duplex mode
...
Notes
* When operating on band A you cannot change to full duplex mode.
* When in single band mode and Band A/B is set to VHF/VHF or UHF/UHF you
cannot change to Full Duplex mode.
* When usin the Full Duplex function, connect an earphone to the SP jack.
using an earphone will prevent feedback that can cause the transceiver to
emit a howling sound."
I have photographed these instructions and transcribed from the photo. For
some reason I photographed the manual not the radio which is a squat fat
two-tone grey thing. It's got a gps built in. Available end 2010, they
said.

http://www.pa3guo.com/webradio.html
Not tested against all platforms (Firefox, Mozilla, ...).
No clue how many simultanious listeners I can handle.
Anyway, I will monitor HO-68 CW beacon today (435.790).
Of course you only hear something when it is overhead at my QTZ (Europe).
If you dont mind, I would be interested to hear:
- if you could connect
- if you noticed the 12 second delay
- how much better your own station is (a lot most likely)
- which browser used
Maybe later I will also monitor AO51/Echo

ARISS ham radio contact planned with IRSEA Institute, Italy
An ARISS (Amateur Radio on the International Space Station) radio
contact is planned with IRSEA, a non-profit Institute for Research
and Education, located in southern Italy.
IRSEA's mission is to provide a bridge between university research
and trade unions and corporations in the fields of education, devel-
opment and innovative research.
The ARISS contact is scheduled Tuesday 5 October 2010 at 15:28 UTC.
The contact will be a telebridge, operated by ARISS ground station
K6DUE, located in Goddard Space Flight Center, Maryland. Stations
in North America may be able to directly hear the ISS downlink on
145.800 MHz.
The contact will be available on EchoLink AMSAT conference server
and IRLP Discovery Reflector 9010. The contact will be webcast on:
http://www.cittadellamediterraneadellascienza.it/
ARISS is an international educational outreach program partnering
the participating space agencies, NASA, Russian Space Agency, ESA,
CNES, JAXA, and CSA, with the AMSAT and IARU organizations from
participating countries.
ARISS offers an opportunity for students to experience the excitement
of Amateur Radio by talking directly with crewmembers onboard the
International Space Station. Teachers, parents and communities see,
first hand, how Amateur Radio and crewmembers on ISS can energize
youngsters' interest in science, technology and learning.

AO-51 Resumes Operation
After a software crash on September 26 aboard AO-51 took the satellite
off the air Ground Station Mark Hammond, N8MH reported that as of
September 29, "The reloading of AO-51 is essentially complete; the bird
is in good order."
The AO-51 Command Team configured the satellite for simultaneous opera-
tion of both the S-band and U-band transmitters. The tradeoff is that
U-band will be low in power-around 250 mW or so. Also, please notice
the use of the 145.880 MHz uplink!
September 29
FM Repeater, V/S-U
Uplink: 145.880 MHz FM (no PL tone)
Downlinks: 2401.200 MHz FM *and* 435.300 MHz FM (at low power!)
Mark said, "This is a great time to work on improving the sensitivity
of your receiver setups! The 250 mW will challenge some of you for sure.
PLEASE be sure to follow the "if you can't hear it, don't try to uplink"
basic rule of satellite operation."
If the satellite supports the dual downlink mode OK, controllers may
extend the V/S-U mode a few days past the original mode schedule in
order to give mode S operators a fair shake at some operations and
testing--while at the same time allowing some low power mode V/U
operations.

September 27, 2010
1. School Contact
English Estates Elementary School in Fern Park, Florida had a scheduled
contact on Thursday, September 30 at 18:00 UTC. Through hands on
activities,
students will learn about space satellite tracking. The school has an
established liaison with the Lake Monroe Amateur Radio Club and an
on-campus
ham radio emergency operations station.
2. Astronaut Doug Wheelock Chats with New York Students
On Wednesday, September 22, students from Windsor Central and
Owego-Apalachin
School Districts in New York participated in an Amateur Radio on the
International
Space Station (ARISS) contact with astronaut Doug Wheelock, KF5BOC.
Wheelock,
a graduate of Windsor Central High School, fielded 16 questions put to him
by
the youth during the ISS pass. The school districts collaborated with the
area's
Kopernik Observatory and Science Center to put together an education
program
for the students which included topics on space, radio communication,
satellites
and rocketry. The final outcome of this project will be the purchase of
amateur radio equipment for each school and the formation of amateur radio
clubs for the youth.
3. ARISS International Team Meeting Held
The monthly ARISS-International team meeting was held on Tuesday,
September
21.
Topics of discussion included the recent ARISS elections, Columbus Module
equipment
and a status on ARISSat-1. Minutes have been posted.
See: http://www.rac.ca/ariss/arisstel2010-09-21.htm
4. MAI-75 Experiment to be Activated
The Russian ISS crew members will activate the MAI-75 (Moscow Aviation
Institute)
experiment on September 27 - 29. The activity is planned for 2 runs per
day
over
Western Russian between approximately 07:00 - 11:00 UTC.
5. Amateur Radio Newsline Covers ARISS Activities
On September 24, the Amateur Radio Newsline Report 1728 included two ARISS
related
stories. "Ham Radio in Space: ISS ATV Activated Briefly on September
14th"
is about the recently held MAI-75 Slow Scan Television session. The second
item,
"Ham Radio in Space: ARISSAT 1 Near Completion" covers the final
preparations of
ARISSat-1 prior to shipping to Russia. Both stories may be found

At the (British) National Hamfest yesterday I had a play with the
pre-production model of the THD-72E and asked about full duplex.
I couldn't get into full duplex on the menu and had to give the set back
but I insisted onthe question in the name of AMSAT and they went to the
manuals while some other guys played with it.
On the second manual(printed off the cdrom) - which they said was about
the packet function - there was the following instruction:
"FULL DUPLEX
Ths transceiver is also capable of simultaneously transmitting and
receiving signals. So it is possible to transmit audio on the current
band while receiving packet data on the other band (data band).
1 Set operation band to band B
2.Press [F DUP] to enter Duplex mode
...
Notes
* When operating on band A you cannot change to full duplex mode.
* When in single band mode and Band A/B is set to VHF/VHF or UHF/UHF you
cannot change to Full Duplex mode.
* When usin the Full Duplex function, connect an earphone to the SP jack.
using an earphone will prevent feedback that can cause the transceiver to
emit a howling sound."
I have photographed these instructions and transcribed from the photo.
For some reason I photographed the manual not the radio which is a squat
fat two-tone grey thing. It's got a gps built in. Available end 2010,
they said.

Lesson learned ''number 1": HAMs use Firefox !
So: I fixed my poor HTML just a few minutes ago.
Now also Firefox users should be able to listen in.
Next are a few HO68 CW beacon passes coming up:
19:02-19:20utc HO68 beacon (41 degrees)
20:49-21:08utc HO68 beacon (56 degrees)
See if you can hear the beacon stronger yourself as via my WEB station.
A more scientific way of saying the same:
"My ground station will in the next few hours download telemetry
from an experimental satelliet in space (HO-68) and feed the audio
of the beacon live on the internet for further analisys by users."

13:41-13:53utc AO51 435.300 (13 degrees)
15:17-15:32utc AO51 435.300 (64 degrees)
16:57-17:11utc AO51 435.300 (21 degrees)
17:18-17:33utc HO68 beacon
