RadFxSat(Fox-1B) Passes Mission Readiness Review
The RadFxSat (Fox-1B) Mission Readiness Review was held Saturday
morning, April 29th, at the Cal Poly campus in front of a board
representing
Tyvak, Cal Poly, and NASA.
The purpose of the review is to verify that all requirements are met for a
safe and successful launch and deployment. I presented 81 powerpoint
slides covering all of the ICD (Interface Control Document) requirements,
mission, operations, and deorbit.
At the conclusion of the presentation including questions answers, the
panel
unanimously approved RadFxSat as ready for flight. The next milestone will
be integration into the P-POD with launch scheduled NET (No Earlier than)
September 23, 2017 aboard a Delta II at Vandenberg AFB.

AMSAT at the Dayton Hamvention -- Call for volunteers
The Dayton Hamvention is less than three weeks away!
It is time to be creating your shopping list and making your travel plans.
Last year, we had 45 people assist with the AMSAT booth at Dayton. We've
had a good response so far to our call for volunteers, but we could really
use another 10-15 people.
The 2017 Hamvention is May 19-21 in Xenia, Ohio. Would you consider
helping AMSAT at the Hamvention this year?
The interaction with AMSAT members, satellite operators, designers, and
builders makes the whole experience a lot of fun. Meet or renew
acquaintances, exchange operating tips, and find out what antennas,
software and equipment other AMSAT members use. We currently expect
most of the AMSAT senior officers and board members to be there too.
If you're an experienced operator, great! We can use you and your
experience.
If you've never operated a satellite before, but want to learn more,
that's OK. We can use your help too.
Whether you're available for only a couple of hours or if you can spend the
entire weekend with us, your help would be greatly appreciated.
Please send an e-mail to Steve, n9ip@xxxxx.xxx if you can help. Thank you!

HamRadioNow: Look! Up in the Sky!
The bulk of this episode is an on-location interview with two Raleigh NC
area hams who gave a couple of live demonstrations of operating through
satellites at the Raleigh Hamfest, April 15, 2017.
There?s some banter between hosts David Goldenberg W0DHG and Gary
Pearce KN4AQ back in the studio. And toward the end Gary announces a
Viewer Challenge that we?ll detail down below.
The satellite hams are John Brier KG4AKV and Tucker McGuire W4FS. At 18
years old, Tucker is a relatively new ham who first started operating
satellites
last summer, and quickly jumped into the deep end. John?s been around
longer, but ham radio satellites and space operation captured his focus,
too.
He produces videos about it on his YouTube channel, Space Comms.
Gary talked to John and Tucker after they completed their second demo,
and he edited a little of each demo into the interview.
There?s video of all of both demonstrations on YouTube. John shot himself
operating through ?Saudi-Sat? SO-50, a ?Mode J? FM crossband repeater
(145.850 MHz uplink and 436.795 MHz downlink). John used three cameras
(including a GoPro on a headband for a unique view). Gary edited the video
and put it on the HamRadioNow YouTube channel as an extra bit if video.
Gary added two more cameras to the mix to shoot Tucker operating through
FO-29, a Japanese satellite that uses a 100 kHz wide ?linear
transponder? for
mostly SSB and CW (and NO FM, please) between two meters and 70 cm.
There?s a few minutes of that demo in this episode, and the whole thing is
on John?s Space Comms channel.

AMSAT-UK test ESEO payload command uplink
AMSAT-UK are providing an amateur radio 1260/145 MHz FM transponder
and a 145 MHz BPSK telemetry beacon for the European Student Earth
Orbiter (ESEO) satellite.
Over the weekend of April 22-23, 2017, AMSAT-UK members met at the
Surrey Space Center to conduct some final testing of the command uplink
on the Engineering Model of their payload which will launch on the European
Space Agency ESEO mission.
The payload, which will transmit 1k2 and 4k8 BPSK telemetry on
145.895 MHz, was set up in the Arthur C Clarke building, with the
AMSAT-UK team sending commands on L-band (1260 MHz) from some
distance away in the university grounds. A large string of attenuators
simulated the path loss to low Earth orbit, while the VHF telemetry
confirmed
the level of signal received at the ?spacecraft antenna? and that the
commands
had been executed correctly.
With the lab and range testing declared a success, work now begins on
constructing the Flight Model hardware. This is due for delivery by the
middle of
the summer so that it can be integrated into the 50 kg microsat. ESEO is
expected to be launched late this year or in the first quarter of 2018.

ISS Commander Peggy Whitson, ex-KC5ZTD, Sets New US Record for
Time in Space
Current International Space Station (ISS) Commander Peggy Whitson,
ex-KC5ZTD, this week broke the record for cumulative time spent in space
by a US astronaut. President Donald Trump -- with daughter Ivanka Trump
and astronaut Kate Rubins, KG5FYJ, joining him in the Oval Office -- called
Whitson on April 24 to congratulate her on her accomplishment. With Whitson
for the call on board the ISS was astronaut Jack Fischer, KG5FYH, who
arrived
on April 20 for his first mission aboard ISS.
"Peggy is a phenomenal role model for young women, and all Americans, who
are exploring or participating in STEM education programs and careers,"
President Trump said. "When I signed the INSPIRE Women Act in February,
I did
so to ensure more women have access to STEM education and careers, and to
ensure America continues to benefit from the contributions of
trailblazers like
Peggy."
Whitson tweeted back, "Thank you, Mr. President, for the great
opportunity to
highlight the research we are doing up here aboard the space station and
beyond!"
Last November, Whitson, 57, launched to the ISS on her current mission,
with
377 days in space already under her belt, and broke the 534 cumulative-day
record in space held by Jeff Williams, KD5TVQ. Whitson became the first
woman
to command the space station in 2008, and on April 9, she became the first
woman to command it twice. She also holds the record for most spacewalks
by a female astronaut.
"This is an inspirational record Peggy is setting today, and she would
be the
first to tell you this is a record that's absolutely made to be broken
as we
advance our knowledge and existence as both Americans and humans,"
said NASA acting Administrator Robert Lightfoot.
This is Whitson's third long-duration stay on board the space station, and
her mission was recently extended for another 3 months. Instead of
returning to Earth in June as originally planned, Whitson will remain on
the
ISS until September, returning home with Fischer and Russian cosmonaut
Fyodor Yurchikhin, RN3FI.
Whitson first served aboard the ISS in 2002 as part of the Expedition 5
crew,
was the Expedition 16 commander some 5 years later, and has conducted
numerous Amateur Radio on the International Space Station (ARISS) contacts
with students on Earth.
Whitson has since let her Amateur Radio license lapse.

Satellite Shorts from All Over
Saint Barts satellite operation
AI5P, N0KV, W0ZA and WD0E plan to operate from Pointe Milou, St.
Barthelemy Island (IOTA NA-146/Grid Square FK87) from October 17 - 26.
Operation will be on 80-10 meters (SSB/CW/RTTY) with satellite operation
by WD0E. Conditions may largely limit most activity to 20 meters and down.
Operating 160 meters is being considered; however, no antenna option is yet
finalized.
Satellite operation will take place on several satellites. A satellite
and pass schedule will be announced on the AMSAT-bb in advance.
Equipment includes three Elecraft K3's and two 500 watt Elecraft amps.
Antennas include a SteppIR crank IR vertical for 80-10 meters, a folding
hexbeam by Folding Antennas (Germany) on 20-10 meters, LPDA's on 20
and 17 meters and verticals on 30 and 40 meters.
Operation will be as continuous as conditions warrant. The Colorado
operators have decided to use FJ/N0KV as their callsign while AI5P will be
active as FJ/AI5P.
FJ/N0KV logs will be updated to LOTW while Rick's logs (FJ/AI5P) will
not since he continues to be an analog guy with an actual key and pen/paper
log. Paper QSLs will be available from both N0KV and AI5P direct and via
the bureau. US addressees send SASE; addressees outside the US should
send SAE plus $2 for return postage.
Use of Club Log is not anticipated.
Further information will be published as the trip approaches.

Yesterday was an 'open day' at our local radioclub. The radioclub is housed
in a scouting building and several scouts came to see what we were doing,
soldered a very simple electronic light and showed some real interest in
radio.
I noticed the ARISS contact with the school in Greece was during this open
day so I told the club I would demonstrate this and brought the arrow
antenna and a simple handheld radio to show the other amateurs and the
visitors that it is possible to hear an astronaut with simple means.
The announcement that we were going to hear an astronaut was received with
great joy and everybody who was there at the time came out to hear it.
After a few (tense) minutes the voice of the astronaut came through and we
al heard clear audio. Even some of the radio amateurs were surprised how
easy it is to receive signals from space.
For as far as I know nobody there understood greek so it was just the idea
of hearing an actual astronaut talk that held a crowd.

Subject: [amsat-bb] Receiving with an rtl-sdr, desense on transmit
Message-ID: <20170430195723.GA28001@xxxxxx.xxxxxx.xx>
Content-Type: text/plain; charset=us-ascii
I am trying to go full duplex 'on the cheap' by using an rtl-sdr on the
receiving side, keeping an ear on the downlink while transmitting.
Software wise this all seems to work. I use a linux setup, with gpredict to
track the satellites and calculate doppler shift. The gqrx sdr software can
act like a radio that gpredict can control so the receiving frequency is
correct. It controls both gqrx as receiver and my ft-857 as transmitter.
Hardware wise I bought an rtl-sdr with a small preamp and built the pre-amp
into a metal case.
This works up to the level where I received AO-73 and received a weak
Fox-1A and recorded the pass.
But when I pressed the transmit button on the FT-857 (tuned to the 70cm
uplink frequency) the receiver (tuned to the 2m downlink frequency) went
deaf.
Some testing with the arrow antenna and transmitting on 70cm shows the
preamp turns deaf on 2 meter. Even without the preamp but with the internal
amplifier of the rtl-sdr this happens. Setting the gain to 'automatic'
causes a huge drop in signal and takes time to recover.
Complete details, experiences, pictures of my setup and details I left out
start at
https://idefix.net/~koos/newsitem.cgi/1490542545
- has anybody done anything with an rtl-sdr as the receiving side, how do
you setup the gain? Is there a solution to fix this?
- specific to fox-1a: I am reading somewhat different reports of the
downlink and uplink frequencies when I search with google. I hope
http://www.amsat.org/?page_id=4690 is right. I did notice the signal is
weak even with an amplifier.
Thanks for any insights and tips,

Then I go into radio control in SatPC32 and define the proper com ports for
radio 1 and radio two. I exit SatPC32 and then reopen.
As SatPC32 opens I get two error messages, one for each com port defined in
radio control:
"Could not open COM3 for Radio 1.
Check whether COM3 is available on your system..."
I get the corresponding error message for COM4 on Radio 2.
Any linux experts who can help me with ideas on how to get the USB-COM
devices recognized in Wine?
Thanks

Hi Koos, I suggest not using preamp since the RTL-SDR has way too much gain
already, unless your preamp is narrow band (has a?built in pass-band filter,
ie: 144 -148MHz) it may be useful as a filter, but in any case you need to
adjust manually RTL-SDR AGC to a minimum necessary gain. AO-85 uplink freq
435.180 ST 67.0hz, dwlink 145.980.

Subject: [amsat-bb] Receiving with an rtl-sdr, desense on transmit
I am trying to go full duplex 'on the cheap' by using an rtl-sdr on the
receiving side, keeping an ear on the downlink while transmitting.
Software wise this all seems to work. I use a linux setup, with gpredict to
track the satellites and calculate doppler shift. The gqrx sdr software can
act like a radio that gpredict can control so the receiving frequency is
correct. It controls both gqrx as receiver and my ft-857 as transmitter.
Hardware wise I bought an rtl-sdr with a small preamp and built the pre-amp
into a metal case.
This works up to the level where I received AO-73 and received a weak
Fox-1A and recorded the pass.
But when I pressed the transmit button on the FT-857 (tuned to the 70cm
uplink frequency) the receiver (tuned to the 2m downlink frequency) went
deaf.
Some testing with the arrow antenna and transmitting on 70cm shows the
preamp turns deaf on 2 meter. Even without the preamp but with the internal
amplifier of the rtl-sdr this happens. Setting the gain to 'automatic'
causes a huge drop in signal and takes time to recover.
Complete details, experiences, pictures of my setup and details I left out
start at
https://idefix.net/~koos/newsitem.cgi/1490542545
- has anybody done anything with an rtl-sdr as the receiving side, how do
? you setup the gain? Is there a solution to fix this?
- specific to fox-1a: I am reading somewhat different reports of the
? downlink and uplink frequencies when I search with google. I hope
http://www.amsat.org/?page_id=4690 is right. I did notice the signal is
weak even with an amplifier.
Thanks for any insights and tips,

The only other thing I've needed to do in general (haven't tried SatPC32
specifically), is to add the group "dialout" to your account. Or run
SatPC32 under wine as root (not recommended, just on principles).
Good luck,

Koos,
I am working on a similar project and started with an RTLSDR device. I
have since switched to using an SDRPlay RSP2, due to its better input
filter, Digital resolution, and shielding.
One problem with these RTLSDR devices is that they have very broad-banded
input filters. Consequently, the transmitter signal, although
attenuated, is
received by the RTLSDR, causing it to desense. You will need add more
filtering to sufficiently attenuate signals outside of the receiver band
of interest.
