An SD card image with the latest FoxTelem (V1.08r) is now available to
download from http://burnsfisher.com/AMSAT/FoxInABox. Look at the
readme.txt file for details. This SD card image is the same as what is
burned on SD cards currently shipping from the AMSAT store.
CAUTION! It is over 3GB long! There is a shorter file there (V1.07y) but
it has an older FoxTelem and it does not support Raspberry Pi 4.
Remember, you can also upgrade your existing FIAB SD card to the latest
FoxTelem. See the text file "Updating FoxTelem on your Fox-in-a-Box.txt"
in the same directory.

Nick,
I also have several of their (ARR) preamps, some with the choke for
power-over-coax and some without the choke for power via an independent
line. I have been following this thread and it is a little confusing at
times as EME requirements get lumped in with the satellite requirements. I
do both Sats and EME and I see them as very different animals. With EME
you are running many hundreds of watts probably a KW or more. Many EME
stations used separate feeds for Tx and Rx. The path loss is on the order
of 252 dB which means noise figure is really important. The
required relays in an EME preamp system can cost more than the preamp
itself. The switching requirements are pretty steep and everyone uses a
sequencer. The noise figure of the preamp is everything
For satellite work 20 watts is QRO. Most of us have gotten used to RF
switched preamps and that means no sequencer. In satellite work there is
most often a single feedline for Tx and Rx. Noise figure while still
important is not as strigent as with EME. The one thing a
satellite preamp has in common with an EME preamp is the need to be mounted
as close to the antenna as possible to be maximally effective.
The challenge I see with many of the cheaper preamps is all you are getting
is the preamp. Chances are you need to figure out how to box it up in a
weather proof enclosure. With a single feedline you will probably need at
least two relays to switch it in and out of line. Either you are going to
need to build your own RF sensing circuit or most probably invest in a
sequencer.
My point is when shopping around just make sure you are comparing apples to
apples A bare bones preamp with no switching circuit may look cheaper
until you look at everything else you are going to need to put it into
service.
73,
John

I have SatPC32 controlling my IC-9700. I'd like to control HDSDR (and my
RSP2 SDR) as well at the same time.
I acquired VSP Manager from K5FR as a solution but I struggle to get it to
work with both radios simultaneously. The virtual ports show up ok and I
can configure them but I don't get control of the SDR. And the IC-9700
control stops. Yes, the ports used for each radio are different.
Should I use the DDE function as described in section C3 of the SatPC32
manual?
I'm using Win7 and USB ports, of course.
Anyone have some tips to share?

Bob,
If HDSDR will do the same as SDR Console, and emulate a TS2000 as far as CAT
is concerned, you could use the helper app I use that a friend of mine - Tom
M0LTE - wrote for me:
https://github.com/M0LTE/satpc32-dde-utils
It listens to the SatPC32 DDE stream, and pushes the frequency and mode to
SDR-Console (or whatever is configured to pretend to be a TS2000 on the COM
port you specify) in real time.

John (M5ET)

Content-Type: text/plain; charset=UTF-8; format=flowed
My satellite rig is two HTs running to an Arrow antenna. Trying my best
to operate full duplex. When operating V/U I am using the UHF side of
the Arrow duplexer as a high pass filter between the UHF antenna feed
point and the UHF HT to keep the 2 m transmit signal from desensing the
UHF receive.
But it only sort of works.
This set up leaves the VHF end of the duplexer open and just hanging.
Would this setup work better with a 50 ohm load across that empty
connection? (Sorry if this is a dumb or elementary question, but I'll
never find out if I don't ask.)
All helpful insights are welcome.

Hi Steve,
I asked myself a similar question and decided to measure things both
terminated and un-terminated. Bottom line is you want to terminate that
unused port.

Steve,
I have had great success using a diplexer on the VFH side to eliminate
desense on V/u satellites.? I do not use a dummy load/terminator on the UHF
port.?Recently, I switched to a Mini-Circuits BLP-200+ as it has a smaller
form factor.? Note, the BLP-200+ has an?advertised? 0.5W power limitation.?
I have used mine with 10W output with no smoke released, yet.? Your mileage
may vary.

I use triplexers extensively here and they do a wonderful job of
eliminating desense on Mode B (2m down, 70cm up)
*The key is using good ones, not jun They key is using good ones, not junk.
*If there is no reliable published spec for port to port isolation...it's
junk.
All of mine are Comet CF-514J and isolate 2m/70cm/HF and can handle 500 to
800 watts on 3 segments. The port to port isolation is 60 dB, and I get 0
desense or intermode on my 2m downlink, even running 500w out on HF on the
same coax that has both my 2m and 70cm Eggbeaters. I also use an ARR GASfet
preamp in the 2m side...no issues whatsoever.
============================================
My main sat setup also uses Triplexers (and the unused ports are all
terminated in 50 ohm loads (little bnc terminators).
70cm Tx > Triplexer 70cm Port In > 1/2" hardline Out to Tower > Dual Band
Interlaced Yagi (common feed point)
HF Port on that Triplexer is 50 ohm terminated in shack.
===========================================
I have even run 2 triplexers back to back for increased isolation to keep
QRO HF out of my 2m Rx. Works just fine, and does not kill sensitivity for
SAT work.
My Noise Floor is calibrated to -95 dBm for a 50 ohm resistor on 2m. The NF
with an antenna is -91 dBm. I see passband noise on all linear sats (Mode
B), with typical peak signal strength of -60 dBm. Typically,. I see 25 dB
SNR when the passband noise is included.
...and not a hint of desense or intermod. I highly recommend the Comet
Triplexers, even if you only need a duplexer, because the port to port
isolation is higher. I found them as cheap as $28 on line...and as much as
$35 on line. I bought 4 of them when I found them at $28.
Maybe this will help someone get the most out of their sat setup, and
eliminate what can be a very frustrating problem.

Call for Proposals?
?
Current Proposal Window is October 1, 2019 to November 30, 2019
?
Upcoming Proposal Window is February 1, 2020 to March 31, 2020?
?
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew member on board the ISS. ARISS anticipates that the contact for
proposals submitted in the proposal window now open would be held between
July 1, 2020 and December 31, 2020.? ARISS is happy to announce a second
proposal window will open February 1, 2020 for contacts that would be held
between January 1, 2021 and June 30, 2021. Crew scheduling and ISS orbits
will determine the exact contact dates. To maximize these radio contact
opportunities, ARISS is looking for organizations that will draw large
numbers of participants and integrate the contact into a well-developed
education plan.?
?
The deadline to submit proposals for contacts between July 1, 2020 and
December 31, 2020 is November 30, 2019.? The proposal window for contacts
between January 1, 2021 and June 30, 2021 will open on February 1, 2020 and
close on March 31, 2020.? Proposal information and documents can be found at
www.ariss.org. Two ARISS Introductory Webinar sessions will be held on
November 7, 2019. The first is at 6:00 PM ET and the second is at 9:00 PM
ET. The same material will be covered during both sessions, so choose the
session that best fits your schedule. The Eventbrite link to sign up
is?https://ariss-introductory-webinar-fall-2019.eventbrite.com?.
?
The Opportunity?
?
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.?
?
An ARISS contact is a voice-only communication opportunity via Amateur Radio
between astronauts and cosmonauts aboard the space station and classrooms
and communities. ARISS contacts afford education audiences the opportunity
to learn firsthand from astronauts what it is like to live and work in space
and to learn about space research conducted on the ISS. Students also will
have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight
and the complexity of scheduling activities aboard the ISS, organizations
must demonstrate flexibility to accommodate changes in dates and times of
the radio contact.?
?
Amateur Radio organizations around the world with the support of NASA and
space agencies in Russia, Canada, Japan and Europe present educational
organizations with this opportunity. The ham radio organizations' volunteer
efforts provide the equipment and operational support to enable
communication between crew on the ISS and students around the world using
Amateur Radio.??

About ARISS:
?
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS).? In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

Just watched the latest batch of Starlink sats pass quickly over the
Denver area.? They were spread out more than I expected.? Very faint in
a sky that was still pretty light.? 10 minutes later they would have
been eye catchers.
