Yuri's hospitality was incredible! Photos and a write-up will be
forthcoming. We are in the process of moving to FL, so it may take a while.
For those who have sent QSL cards to us, we have them and the replies WILL
go out prior to our leaving VA. Please be patient and bear with the
pandemonium that comes with moving a family of six!

Yuri has left Norfolk and is on his way
to Mariel Cuba. You may have seen him at
anchor out in the bay after he left the
berth. A fuel barge was next to him filling
up his tanks!
Yuri has sent mail to the following stations:
KD8CAO W5PFG W5CBF N5UXT KJ4MCZ KO4MA WA4NVM
K4FEG N2PPL K9HF K8II W1PA WN9Q. If you don't
receive something in two weeks, please let me
know. As you can imagine, it is no easy job to
confirm so many contacts with so many different
stations. He does what he can considering the
time he can spare. It is a never ending job for
him.
You may have heard that WX4TV and his family were
able to visit the ship yesterday just before it
sailed. Yuri was very busy with his agents and
last minute paperwork but one of the crew gave
them a tour of the ship. I expect that Jim will
be sharing some photos/video of that visit.
We are very fortunate to have someone like Yuri
take an interest in operating the satellites in
hundreds of water grids. It's fun to make all
of those contacts, but it is also a lot of work
to get confirmations out when you are not at home.
Yuri is an amazing operator and ambassador for
ham radio. His callsign is recognized by vhf'ers
around the world. Good luck to everyone trying to
work him. The route down to Cuba should be new for
many operators.

The keps certainly look good here in Oregon. I had a predicted PSAT AOS out
over the Pacific Ocean at 16:02:01Z and picked up the first PSK-31 beacon at
16:02:16Z.

Today, (over USA) I am finding satellite to be 8.5 minutes behind the
ULTRAsat3 TLE. And get a very good match. I am listening to the PSK31 *FM*
downlink on 435.350 +/- 5 KHz and swinging the beam and watching Doppler to
confirm I am tracking well.
But Nico (below) sees it on time in Europe. I cannot explain the
difference... I am using the elements with an EPOC of 15 140.6701389 (shown
below) which were released at separation. There have been no updates yet.
As soon as I get them I will post them.
I did just turn on 3 USA and 3 European packet bulletins. And adjusted the
MA spacecraft counter so that the right bulletins will come on over the
right continents. DIGI will remain off since PSK31 is working so well!

Yesterday and today I performed detailed doppler measurements on high PSAT
passes, both on 70 cm and on 2 m.
I found that yesterday the satellite was 10 seconds early and today 14
seconds early, compared to the ULTRASat3 TLE set.
I wonder why you think it is 6 minutes late. Maybe you were confused by the
ASCII telemetry transmissions on 145.826 MHz of UoSAT-OSCAR 11, which passed
about 6 minutes after PSAT?

Bob,
Got a chance to listen to the PSAT PSK beacon this morning on what was to be
the 1246Z pass. I used HDSDR controlled by SATPC32 to get the passband.
HDSDR ot Digipan through a virtual audio cable to decode. The Doppler was
off which makes sense with the Keps that are off from what was posted. Saw
some initial short transmissions with gaps in between and then a rather long
run of transmissions. I never saw any other PSK31 activity besides the data
beacon. Someday soon I will give transmissions a shot.
Attached is a file with the data I decoded this morning. Approximate time
stamp of first beacon is at the head of the file.
I know you have made some reference in BB emails as to what some of the
parameters generally mean. Will there be more details or a telemetry
decoder soon?
I love the PSK transponder idea the University has created and look forward
to giving it a try.

Was PSK TLLM channel on 315 Hz or 375 Hz?
Were you also hearing PSAT 1200 baud packets on 145.825 at same time?
AL0I suggests some of us might be hearing BRICsat (TLM on 375 Hz)
While others (me) are hearing PSAT (TLM on 315 Hz) simultaneouisely with
PSAT packets on 145.825

NEVERMIND! End of SUBJECT Thread...
The original TLE is good!
***I must have made a typo entering TLE into Instantrack and had to retard
time by now 8.5 minutes to get it to work.
But with same TLE in SATPC32 (copy pasted instead of manually enered) then
predictions ARE CORRECT.
So FORGET this THREAD. TLE's from launch day *are* OK.
Back under my rock. Besides PSAT's PSK ID's as W3ADO-5 on 315 Hz and
BRICsat's as W3ADO-6 on 375 Hz.
Should be flying very very close to each other. Separation spring between
them was only 1mm long.

AMSAT 2015 Field Day Announcement - June 27-28
It's that time of year again: Field Day! Each year the American
Radio Relay League (ARRL) sponsors Field Day as a "picnic, a campout,
practice for emergencies, an informal contest and, most of all, FUN!"
The event takes place during a 24-hour period on the fourth weekend
of June. For 2015, the event takes place during a 27-hour period from
1800 UTC on Saturday June 27, through 2100 UTC on Sunday June 28,
Those who set up prior to 1800 UTC on June 27 can operate only 24
hours.
The Radio Amateur Satellite Corporation (AMSAT) promotes its own
version of Field Day for operation via the amateur satellites, held
concurrently with the ARRL event.
If you are considering ONLY the FM voice satellite SO-50 for your
AMSAT Field Day focus - don't - unless you are simply hoping to make
one contact for the ARRL rules bonus points. The congestion on FM LEO
satellites was so intense in prior years that we must continue to
limit their use to one-QSO-per-FM-satellite. This includes the
International Space Station. You will be allowed one QSO if the ISS
is operating voice.
You will also be allowed one digital QSO with the ISS or any other
digital, non-store-and-forward, packet satellite (if operational).
Many good contacts can be made on the linear transponder satellites
including AO-73, FO-29, and AO-7. During Field Day the transponders
come alive like 20 meters on a weekend. The transponders on these
satellites will support multiple simultaneous SSB or CW contacts.
The 2015 AMSAT Field Day event is open to all Amateur Radio
operators. Amateurs are to use the exchange as specified in ARRL
rules for Field Day. The AMSAT competition is to encourage the use of
all amateur satellites, both analog and digital.
AMSAT Field Day information is also posted on the web at:

Radio Amateur Sworn In as New NASA Deputy Administrator
Massachusetts Institute of Technology (MIT) professor Dava Newman,
KB1HIK, has been sworn in as the deputy administrator of NASA.
President Barack Obama appointed Newman last October, and the US
Senate confirmed her appointment on April 27. The swearing-in took
place on May 15 in her MIT office in Cambridge. Newman is Apollo
Professor of Astronautics and Engineering Systems and the director
of the Technology and Policy Program at MIT. She started her
official duties as NASA's new deputy administrator on May 18 at the
agency's headquarters in Washington, DC.
"I'm very excited to be at NASA," said Newman. "I'm looking forward
to being a part of the agency's work to expand humanity's reach into
space, advance our journey to Mars and strengthen America's
leadership here at home."
NASA Administrator Charles Bolden, ex-KE4IQB, said he's long admired
Newman. "Her talents and skills as an educator and technological
innovator will bring a new energy to our NASA leadership team, and
I'm ecstatic to have her on board," he said.
Newman had been on the MIT faculty since 1993. Her research has
included modeling human performance in low and microgravity
conditions, examining the dynamics and control of astronaut motion,
and the development of assisted walking devices for the physically
handicapped. Possibly her most prominent project has been the
development of the BioSuit, a skintight spacesuit that would give
astronauts unprecedented comfort and freedom in exploration of
planetary surfaces and extra-vehicular activity.
An avid sailor, Newman has circumnavigated the globe.

PSK31 and APRS CubeSat Status Update
Martin G8JNJ reports receiving the PSAT PSK31 FM downlink on the
online SUWS WebSDR located at Farnham near London. At 22:30 GMT on
May 21, 2015 Bob Bruninga WB4APR posted the following update on the
AMSAT Bulletin Board about the three USNA CubeSats PSAT, BRICSAT and
USS Langley along with a guide on how to use the PSK31 transponder.
We now have heard 4 of 5 transmitters from our 3 spacecraft all
still in a close cluster:
* PSAT packet is OK but WOD not working (no digipeating for users yet)
* PSAT PSK31 downlink is ok [remember, it is FM!]
* BRICSAT telemetry has been heard but is cycling OFF due to low power
* BRICSAT PSK31 downlink (also FM) has also been heard barely (when
ON)
* USS Langley not heard
PSAT CPU shows the 4 day-fail-safe backup reset circuit is not
counting down, so we have lost this (1 of 3) fail safe backup RESET
capabilities. Bad line of code already found. But cannot change it.
PSAT is not properly reporting WOD data and S#? STATUS packets are
being bundled until 255 byte packet length is reached and then it all
comes down at once. Noone has captured any of these long packets.
Please try with PASSALL ON so that you can receive partial packets.
Awaiting permission from BRNO University to authorize HF user
uplinks on PSAT PSK31.
BRICSAT PSK31 transponder is on identical frequencies as PSAT?s.
You can tell them apart because one has PSK Telemetry on 315 Hz and
the other is on 365 Hz. Both on the UHF FM downlink 435.350 MHz
We?d LOVE to hear from USS Langley, and we?d love to capture one of
those long WOD packets from PSAT. Our ground station is only getting
a few packets compared to some submissions from others. Keep it up.
SUMMARY:
145.825 1.5U cubesat ? PSAT 1200 baud AX.25
435.350 same cubesat ? PSAT PSK31 FM ? Brno University transponder
437.975 1.5U cubesat ? BRICsat 9600 baud

2 99993 055.0004 339.9238 0251027 182.3314 074.3075 15.12517086000014
Receiving the PSAT PSK31 FM downlink
Receiving the PSAT (and BRICsat) 435.350 MHz FM downlink is as
simple as placing your PSK31 laptop microphone next to the speaker
on your FM satellite UHF receiver and just watching the waterfall.
What you see is exactly what everyone else sees (its FM). There is
no Doppler added to the tones due to your station?s position relative
to the satellite. But you DO have to retune your FM radio at least 3
times during the pass (+5 kHz, 0, -5 kHz) to stay in the FM passband.
[Note: UK users should remember to selected the wide FM (5 kHz
deviation/25 kHz channel spacing) setting on their rigs]
User uplinks, however, will shift in the waterfall according to each
user?s position relative to the satellite. The shift can be as low
as 1 Hz per second to as high as 6 Hz per second. This is because
the uplink is on 10 meters where the Doppler rate is only 1/15th of
what it would be on UHF.
The TELEMETRY channel at 315 Hz (PSAT) or 375 Hz (BRICsat) is FIXED
with no Doppler since it is generated onboard into the FM downlink
WHAT TO DO:
1) We will need PSK31 authors to open the PSK31 frequency tracking
to accommodate more than 1 Hz per second Doppler tracking. Current
implementations can do 1 Hz/s but completely fail at 3 Hz/s. 2 Hz/s
might work a little?
2) Until then, ANY uplink user that is in line with a direct
overhead pass will have minimum Doppler at the start and end of his
pass (1 Hz/sec) when the satellite is going right at him and directly
away from him. (Though it will be MAX (6 Hz/sec) when it passes over
her/his station).
3) Just turn on MULTI CHANNEL window and let the PSK31 decode
everyone.The ones with the least Doppler at any instant may be
decoded for a while!
USERS can transmit later when BRNO University says it has completed
its tests. Brno provided the transponders for use in the PSAT and
BRICsat satellites.
So start preparing your station to TX PSK31 on 10 meters SSB and to
receive the audio from an FM UHF rig on 435.350 +/- 5 kHz steps of
Doppler.
DOWNLINK Limitations: The UHF downlink signal is only 300 mW and so
a UHF beam is needed on the downlink.
UPLINK RESTRICTIONS: *NOTHING MORE THAN* a Vertical 1/4 wave or
Dipole is authorized on the 10m uplink and no more than 25 Watts
(for now).
Remember a 1/4 wave vertical is the ideal antenna because it
maximizes the signal at lower angles and tapers the signal as the
satellite gets closer. This keeps user uplinks about the same during
a pass. Strong stations just drive down the AGC and ruin it for
everyone.
Use minimum power!! Remember, this is crossband FULL DUPLEX so you
can see yourself in the downlink just like everyone else can see you.
Act accordingly. And of course DO NOT TRANSMIT if you cannot see the
waterfall ? Duh!
Enjoy!
