It seems that any time I leave SatPC32 to operate my FT-857 on HF,
SatPC32 leaves my radio in split mode. Is there a setting or something
else I have missed somewhere?

I need someone interested in adding quadrature 2 meter antennas
to the outside of a 10" diameter sounding rocket by middle
May...
This launch is going to space (100 miles up) from White Sands on
a sounding rocket to then come back down by parachute. Antennas
cannot stick out far (maybe an inch?) but can be bent back along
the surface. Temperatures will approach 800F during the 10
minute flight. G' forces will be huge.
The payload will be (what else) an APRS trackign system and
2-way APRS communications transponder.
So, if anyone wants to take on this antenna, lemme know.
All I need is the detail design and analysis. The machining is
paid-for. Oh, it also needs quadrature GPS antennas, but that
can just be a pair of 1.5" monopoles...

Sorry for late notice
I will check to see if AO 7 in in Mode B in 20mn.
Then look for me on FO29 and VU52 this evening.
I will post tomorrow's schedule. I plan on being on the 15:50UTC AO7 pass
which will be bes shot for many towards the eastern edge of the footprint. I
will send update later tonight. I also plan on FO29 and VU52 passes during
Wednesday morning HI time.
Have to run to set up. Please note we are experiencing heavy winds today and
it may be difficult handling the ELK antenna. At least the heavy rains have
stopped.

Hi all,
Does anyone know of a commercially available TNC that supports GMSK at 4800
bits per second? I have a KAM-XL which has 9600 bps GMSK, and it seems like
the KPC-9612+ is also close, with 4800 DFSK (or could a DFSK device talk to
a GMSK device?). KISS mode or something similar would also be very nice.
Thanks and 73,

Hi!
Alex XE2BSS will be traveling to grid DM30 tomorrow morning, and will
be out there through Saturday (4/3) afternoon. He will try to work
AO-27 and SO-50 passes from there. Alex will only have FM gear on this
trip, so he won't be able to work other birds from there. Alex will be
in the city of Caborca, in the Mexican state of Sonora - approximately
90 miles/140km southeast of the Lukeville (Arizona) border crossing.
If you work XE2BSS over the next few days, I am his QSL manager. Please
send QSL requests for XE2BSS to me, and please include an SASE with those
QSL requests. I may be able to post updates while he is down there, as
he should have Internet access from there.
Thanks and 73!

I also recently got a Wouxun KG-UVD1P and today gave it a try on HO-68.
My antenna is a long telescopic whip, Diamond RH-770 (quite similar to
Pryme AL-800).
I was very surprised to hear traffic from HO-68 almost immediatelly it
was over the horizon.
There was many very strong stations and I did not manage to get my 5 W
signal through,
but at least the receiver-side seems to be very sensitive. There is
few quirks in the
usage of Wouxun, but with pre-programmed channels and other settings I
probably
can live with it. Anyway Wouxun's felt quality and usability is sheer
improvement
compared to earlier HT offerings from China I've seen.
I have not made comparisons with other radios yet, but to me Wouxun
seems quite promising.
I usually use Yaesu FT-60r with Arrow II yagi for my backyard-portable
FM-satellite QSOs.
The SMA-connector in FT-60 feels quite fragile for long telescopic whips
(Yes, I know KC2BHO's adapters might provide a solution), whereas
Wouxun's casing
provides some support even with standard BNC-SMA(F) adapter, reducing the
stress
caused by a long whip.
In Europe, Wouxun's are available in some reputable vendors, with CE
approval (whatever
it's worth..). Mine came from eBay, though...

I have had several of you ask why I am not on the FM satellites. I actually
have been on FM.
I was recently on AO51 when it was in VU mode. I was on Oahu at the time and
I had blockage from the local mountains and hotels on several passes. Even
being on the 33rd floor did not helps matters but I was able to work a few
people. Many contacts were made in FM mode.
AO27 and SO50 schedules simply conflict with my vacation plans on Kauai,
sorry. There are several Hams on KH6 who are on almost every weekend and
will be happy to work you on those satellites.
There is only one operator on Oahu able to work the linear satellites. He
can only work down to 30 elevation. At my QTH here in Kapaa, HI I can see
the ocean from our deck and I can work the low passes very well that is why
I am concentrating on SSB as this makes the most sense due to the limited
time I am here on the islands.
There are some good morning (HI) passes that I will be able to make and I
expect some fairly busy passes over the next four days. Please make an
effort to show up based on my posts to the AMSAT BB. Again this evening I
worked a pass up Western US Coast into VE and Alaska. I called CQ the entire
FO29 pass with no takers.
I recently messed up an HO-68 FM pass I heard many stations calling me but
my transmit locked up. I finally figured out my SatPC had locked up and this
messed up the transmit. A major opportunity was lost. Blame it on the
technical gremlins. Sorry.
I hope to be on the HO68 FM pass on 4/3/2010 at 18:55 UTC subject to better
weather. We are having strong wind gusts up to 50 mph, the next few days.
Keeping the radios and Antennas intact are top priority. If I am not on the
satellite based on the provided schedule it will mostly be due to the wind.
Thanks for listening to my rant. I have appreciated all the kind notes for
sked requests (many have been successfully completed) and encouraging emails
but I have also been frustrated to be the only station on numerous passes
with a good footprint to Hawaii. Even stations with fixed elevation antennas
should be able to work the SSB sats Let's get some activity going.
I hope this adventure encourages others coming to HI in the future to try a
DXpedition from the 50th state to help those that could not make a contact
with me this time around to get them HI in their logs. The gear all easily
fits in a travel bag!
Aloha, Adrian AA5UK/KH6

OSCAR-11 REPORT 30 March 2010
OSCAR-11 achieved 26 years in orbit on 01 March! It was designed,
built and launched within a period of six months, using commercially
available 'off the shelf' components (COTS). Once again,
congratulations to Professor Sir Martin Sweeting G3YJO, his team at
the University of Surrey and groups of radio amateurs who also
contributed to the project. Unfortunately, the satellite wasn't
transmitting on its birthday, but was heard briefly, three days
later.
This report covers the period from 23 February to 30 March 2010.
During this time the satellite was heard during three passes on 04
March. Good signals were received, and decoded. There was also an
unconfirmed report that it was heard on 25 March.
Due to eclipses, deterioration of the battery and other parts of the
satellite, it's not possible to predict when the satellite will be
heard in the coming months. It is likely that it may be heard
occassionally, by stations tuning around the beacon frequency.
The on-board clock was 263 days slow, when last heard on 04 March.
The increasing error suggests that the clock may be stopping, when
the satellite is in eclipse. Sometimes, the date counter also fails
to increment. However, the retention of the date and time does
suggest that a small amount of power may be still available during
eclipses.
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 REQUESTED!
Please send reception reports to xxxxx@xxxxx.xxx (replace xxxxx by
g3cwv) or post to amsat-bb. If you have a file, please do not send
it but let me know that it is available.
You may also like to add your reception report to the live satellite
status page, on the website set up by David KD5QGR and Bob WB4APR.
The URL is http://oscar.dcarr.org/index.php
The satellite transmits on 145.826 MHz., set receiver to NBFM.
OSCAR-11 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 satellite is now subject to eclipses during every orbit. Long
term predictions indicate that eclipses will occur until 2019, when
there will be some eclipse free periods until 2023. However these
very long term predictions should be regarded with caution, as large
tracking errors can accumulate over long periods of time.
When eclipses started around 2005 the watchdog timer often switched
the transmitter off before the ten day on period had finished, during
parts of the eclipse cycle. When eclipses became a permanent feature
of all orbits, after April 2008, the transmitter switched off within
a single orbit, thus the satellite was effectively non operational.
The satellite unexpectedly started regular transmissions in November
2009. Although there was a small variation in the length of eclipses,
this wasn't enough to explain why the satellite started regular
transmissions. It is possible that a fault developed, which prevented
the watchdog timer resetting when the power supply fails, and now the
watchdog timer settings are no longer retained during eclipses. The
transmitter switches off during eclipses, and the real time clock
stops during most of the eclipse.
When analogue telemetry was last received, in 2005, it showed that
one of the solar arrays had failed, and there was a large unexplained
current drain on the main 14 volt bus. After 26 years in orbit the
battery has undergone over 100,000 partial charge/discharge cycles,
and observations indicate that it cannot power the satellite during
eclipses.
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, although during ten minute passes the clock
increments correctly to within one second. 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 operates on a 20 day cycle. The ON/OFF times have
tended to be very consistent. The average of many observations show
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 .
