John's solution is also one I have used for years: feeding a separate
signal into the receive-only HF input on the TS-2000. I ran this way on
AO-40 as well, taking the 2m signal from the atenna-mounted downconverter
and running it through a Hamtronics 2m-10m converter to both the TS-2000 and
another 10 m rig to independantly monitor the beacon (very handy). Elegant:
no relays, and no danger of ever tranmitting into it. I still have the
Hamtronics converter, now installed in my truck, so I could work the S-band
downink from AO-51 on my FT-100.
For the birdie problem, I used to be able to tune around it with the big
antennas and Landwehr preamp I had at my old QTH (circa 2000-2003).
Seriously--if you have enough signal gain, you can tune above it and then
below it and overpower the damn thing. My setup is more modest now, so I
simply connect an HT for the ocassional AO-27 pass. For SO-50, I find you
can tune below the signal and work most of the pass (except when it is
approaching you on a high elevation pass). Obviously, you can't use
computer control for the receive signal on these two birds. I have had this
rig since November of 2000 and found no other serious complaints (except it
only has one PC port--but that is another discussion).

John, K8YSE posted:
As many of you know, my satellite radio is a TS2000X.
If you have visited my satellite webpage, you have seen
many recordings of AO-27 and SO50 from AOS to LOS. Most
of these recordings were made when I was not sitting in
front of the radio.
At first I used a uhf mobile to hear AO-27 and SO-50. The
problem was that those radios were not computer controlled
so you had to tune for the doppler. That worked fine when
I was in the shack, but it didn't work when I was away. The
obvious solution was another radio that didn't have the birdie
problem, or a simple UHF to 10M downconverter which wouldn't
have the birdie problem. Back in the day, UHF and VHF down-
converters were very popular because we didn't have a lot of
DC to Light radios out there. Now these converters are sitting
in junk boxes and are long forgotten by their owners.
One of the more popular manufacturers of these inexpensive
downconverters was Hamtronics. They made all kinds of stuff
for repeaters etc. At first their products were not that great,
but they evolved into some better designs including their
UHF to 10m downconverters. Unfortunately most downconverter
manufacturers stopped making them when the devices they were using
became obsolete and unavailable. The use of current production
devices required a redesign of their PC boards and since the demand
was no longer there, these products were abandoned.
I was fortunate to find a Hamtronics converter on a qrz.com posting
from several years back. It never sold back then and the owner still
had it. I purchased it and ran some tests on it against the receiver
in the TS2000. It turned out that the downconverter had a slightly
better sensitivity than the TS2000!
The big concern when using a converter or preamp is the fear of
transmitting into it and smoking the front end. But the TS2000
has an auxiliary antenna jack which is receive only and perfect for
a downconverter output on HF. As Drew mentioned, SatPC32 can
compensate for a downconverter and tune the TS2000 for doppler
in the 10m band. This allowed me to track AO-27 AO-51 and SO-50
unattended and make all those recordings without any human
intervention.
A coaxial transfer relay was inserted into the uhf antenna line so
that when the converter was in use, the UHF antenna was switched
to the downconverter input (which outputs to the aux antenna jack
on the TS2000) and the UHF antenna jack on the TS2000 is switched
to a dummy load. So if you transmit on UHF, power goes into the
dummy load and all equipment is safe. When I want to transmit on
UHF (VO-52 and AO-7 mode B), the coax relay switches the UHF antenna
back to the UHF antenna port on the TS2000. The downconverter is out
of the antenna circuit at this point. I did not use the downconverter
when operating on FO-29 so the aux antenna jack had to be switched to
normal in the tS2000, menu #18 (FO-29 is a linear bird that outputs on
UHF, currently not working).
Every owner of a TS2000 that operates satellites needs a UHF to 10M
downconverter. Hamtronics is making a VHF to 10M downconverter now.
If everyone emailed them to encourage them to make a UHF model, they
might just do it. The only other solution is to make one yourself,
or find a used downconverter or transverter that is gathering dust on
someone's shelf. I now have an IC910H and am doing comparisons against
the TS2000. My first impression it that I prefer the TS2000 but that
might be because I'm so familiar with it. I use another TS2000 in the
mobile sat truck but don't have a downconverter for it. I simply use
a uhf mobile for receive on AO-27 and SO-50 since I'm in front of the
radio and don't run it unattended. I have a coax switch to switch
the UHF antenna from the TS2000 to the UHF mobile.
Now that AO-51 is silent, all of the FM operation is on SO-50 and AO-27.
If you have a TS2000, you'll want to investigate the use of a downconverter.

One of those over SE Australia would be a very interesting
proposition - a repeater that could potentially cover all of one
state, parts of 3 others and the ACT. :) In other parts of the
country, you'd get lightly used rural repeaters, which could be
useful for travellers. Wondor how much one of those could be put up for.

High altitude balloons are fun. There's a group here that launches
them as well from Adelaide. Had fun when they installed a crossband
repeater on one of their balloons. Also had a go at decoding
telemetry, but being on the edge of the footprint and with small
antennas, I haven't had much luck with telemetry. :(

Hi Satelliters,
?
Using Keps from Space-Track for ARISSat-1? (37772)? I have been plotting
various parameters including Mean Motion.
Rrecent results were unexpected.
?
From day 328to 334 the daily change in Mean Motion has been exactly the same.
The orbital decay is going at a very steady rate. This is completely
different from earlier observations where there is quite a bit of daily
variation.
?
My interpretation is that the?atmospheric density along the orbital track
has been remarkably unchanged over 6 days or so.
This is something I have not seen before.

Again nothing heard from ARISSAT-1 on the Nov 30 13:43 Z pass. I will be
observing the 13:59 Cincinnati pass on Thursday Dec 1. I believe it may
be out of eclipse long enough to be active. If so, I will be listening,
looking on 145.930 and trying to send SSTV, on 435.750. Hope many others
will also try. Tx and Rx of SSTV has been demonstrated a couple of times
through the Transponder even with its shortened antenna and I believe with
persistence can be done again. This is the last, possible active, useable
pass for my area until mid December. I will be back Dec 18 if ARISSat-1
is still in orbit. Please report any thing received Dec 1. Thanks

With the research and recent "heads up" by Mineo Wakita, JE9PEL, Allan
Biddle, WA4SCA and Clint Bradford, KCLCS it appears there may be only a few
weeks left to receive and experiment with ARISSat-1/RADIOSKAF-V.
On Monday Nov 28 I will be set up to receive voice, CW and SSTV via the

at 14:47 Z pass over Cincinnati. This pass may be too soon after the eclipse

I have used a HamTronics downconverter on my TS-2000x for many years, and it
works perfect.
But, to be clear, I am downconverting the UHF signal into the receive ONLY
jack of the radio, on 10 meters.
This virtually eliminates the birdie problem, and allows for full rig
control with SatPC32 just perfectly.
I have a coax switch on the UHF antenna, for when I need to work the UHF
birds that do not have an output on the birdie freq.
Sadly that it cost about $100.00 to resolve the issue, but that's a small
price to pay to still be able to use all the other features of the radio.

KC9DOA mentions that he still had the birdie problem with a downconverter
and that is understandable.
The TS2000 radiates the birdie and if your downconverter is not shielded or
the UHF antenna is too close to the radio, you might still pick it up.
Simple experimentation will find the right combination to virtually
eliminate the birdie. So try a UHF handi or mobile unit and see if it hears
the birdie on 436.798. Then move things around to see if you can minimize
the effect. I've been able to do that in the sat truck and don't have the
problem at the base station. Try a dummy load on the UHF antenna jack on
the
TS2000 as well. Use quality coax with good shielding.
Drew posted a link to High Sierra Microwave for a UHF down- converter that
is up-to-date in design and performance, all at a reasonable price. The
specs call for a 5v supply but Bill N6GHZ advised that the converter will
operate fine up to 16vdc input. No special supply required. He also
mentioned that the converter will perform well from 432 to 438 MHz. So this
is one possible source of a current production downconverter manufactured by
someone who knows satellites. The output IF is lower but the TS2000
receiver is continuous so there should be no problem. Instead of a 407MHz
offset, use 425MHz and the receiver shifts down to 10MHz for a 435MHz input:
doppler.sqf entry:
AO-27,436795,145850,FM,FM,NOR,425000,0
I've not seen a whole lot mentioned about the Funcube performance when
connected to a big antenna in a crowded RF environment. I've had mine on
the KLM's and the performance is poor because of overload. Cavity filters
work wonders but not everyone has them.
High Sierra also makes front end filters and filter/LNA combinations for the
Funcube as well as other products which make the Funcube more versatile.
It's worth checking out the webpage to see what is available.

Nothing heard from ARISSat-1 this AM Dec 1 during the 13:59 Z Cincinnati
pass, too close to the eclipse. Depending on updated Keps will be checking
mid Dec for renewed opportunities. In the meantime, I hope many stations
in other areas will keep trying to get SSTV through the TRANSPONDER. Henk,
PA3GUO , the Netherlands and I were successful with a picture . (See

All,
The FASTRAC satellites have been in operation for more than a year and the
team has been able to get a
lot of data from them, in great part due to the amazing support from the
amateur radio community. Over the last
month the team noticed that one of FASTRAC-1?s on board microcontrollers
which controls one of the experiments
has not been booting up correctly. The team has done everything possible to
correct this issue apart from turning it
off which can only happen if the batteries fall below an specific charge
level. Since the satellites have been power
positive throughout this whole year the only way this can happen is if the
satellites transmit more often. Given that
one of FASTRAC goals has always been to eventually provide a platform for
amateur radio enthusiasts to use after
the primary mission was over, the team has decided to open up FASTRAC-1 to
the amateur radio community with
the hope as more people use it to digipeat through the satellite, the
battery levels will diminish and cause a hard reset
of the microcontrollers on board. The satellite will be configured so that
amateur radio operators can use it
beginning on Friday Dec 2 at 10:00 AM CST. Starting on this date people
will be able to digipeat through the
satellites. The call sign and frequencies of the satellite are summarized
below and an example of
digipeating through the satellite is also shown in below. To increase the
chances of causing a hard reset, it is
requested that as many amateur radio enthusiasts try to digipeat through
the satellite on the weekend of Dec 10. If
you are successful at digipeating through the satellites or have any
problems doing so please let us know at
fastracsats@xxxxx.xxxx through our Facebook page (
www.facebook.com/fastracsats) or through the forums on our
website (

Mount the down convertor at the aerial/masthead! way out of range for
the spurious
and you can use cheap cable for the 10mtr down feed line!

Are there any online websites that provide orbital predictions for FASTRAC 1 ?
I couldn't find it at http://www.amsat.org/amsat-new/tools/ and www.n2yo.com
lists it but doesn't provide tracking.

CURRENT INFORMATION ON 02-05.11.2011 SERIES OF SPASE EXPERIMENT
?SHADOW-BEACON?
Dear friends!
It was earlier announced that? timetable of SpEx ?Shadow-beacon? sessions on
November 26-27 -2011 was reduced because the crew is newcomers and need much
time to assimilate the experience. For the same reason earlier announced
sessions on December 02-05 -2011 are cancelled all.
Sergey Samburov (RV3DR), the employee of space-rocket corporation "Energia"
which is responsible for an amateur radio on ISS, explains that an observed?
fact that the onboard radio ?Sputnik? was accidentally switched on standard
simplex 145.825 MHz not the ordered duplex 144.36/ 145.825 MHz digipeater
mode because of old age of the onboard gear- it is in use more than 10
years. Some times Sergey has already observed? malfunction? like this.
New radio are to be delivered onboard ISS by April cargo vehicle and Mission
Control Center (TsUP) plans new SpEx ?Shadow-beacon? sessions on May-June
2012. With this reason you are asked not to delete your registration on our
site.
Again? many thanks for those submitted reports and made other assistance!
The results of data processing will be presented on our site.
We wait for further cooperation!
