Hi All,
First of all, thank you all for the QSOs on my trip to HM58. Being a
rare grid these days, I've done my best to keep up to you all. My
initial setup was a FT-857 and a portable home made V/U yagi. Eventually
my brother, CU7BC, lend me his TS2000 so I got upgraded to full-duplex.
It helped a lot, but not being computer assisted I was still floating
around the passband. The problems I face with my home made yagi were far
from over, but still we made it.
I've uploaded all QSOs as CU2ZG to LoTW and eQSL. The accurate grid was
HM58qm, and if you want a more accurate location, please look into
QRZ.com for CU7BC, my brother. All QSOs were established from his lawn.
Those wishing for a paper QSL please let me know. I've logged the
stations (below), so if I missed any please let me know - I took all
callsigns and times from my external recordings.
EB1AO, CT3FM, G7SVF, F0DIH, CU3EQ, KB1RVT, KO4MA, HI8KW, WB8RJY, N1AIA,
N8IUP, K8YSE, F4DXV, DG1EA, F4EJW, KK4FEM, YV4DJY, K4FEG, N8HM.
I couldn't pass this opportunity without adding a remark about over-power.
Being in the middle of nowhere I get to operate satellites when no one
else is on them, while those footprints are entirely over the ocean.
Having the full available power to myself is a great opportunity to
check theories, antennas and setups. Also great to check on satellite's
health, and all those other things only possible where urban noise is
virtually zero. I remember that at the AMSAT Symposium Clayton, W5PFG,
was shouting a quiz at us, and one of the questions was about APRS
satellites. He said that NO-44 digipeater was not entirely healthy, to
which I objected saying that if you find yourself alone on the footprint
you'd find that this particular satellite is still alive.
Having this said, there was no way I couldn't notice that there are some
stations, many (according to my standards), operating way too much power
on linear satellites.
When the satellite's footprint is over water I'm expecting no one but me
or a couple of station where island are seen. Being on an announced grid
expedition, 10kHz from the center frequency, I'd expect that people
would come on looking for me, or at least show up in an orderly fashion.
I was totally wrong.
Once the footprint hits the USA I get flooded by people calling CQ,
almost randomly - "is this frequency in use" still applies for
satellites? - More than half of them are using so much power that now I
can barely hear myself on the downlink. It reminded me of CQ contests
where you must squeeze yourself into a "safe" spot in the spectrum. My
best solution was to move away to some 20kHz from the center leaving my
skeds alone and looking around for me. Some never made it. Those
following me on Twitter found an angry twit of mine saying that "this is
not HF".
This past year using an omni antenna at my home station had me find some
passes where my downlink was nowhere to be found. I'm tempted, now, to
say that the problem was desense caused by over-power from other stations.
Please don't take this as a problem existing only in North America. I
got the same thing on European passes. I'm sure it happens all over the
World.
The passband is a limited resource. The satellite is not infinite. Power
is not infinite. Use it wisely.
Thank you All for this Christmas op. It was great talking to friends again.

The packets I am seeing on APRS.fi look like W4DEX is using UIview32 to
send the packets directly to the APRS-IS network via an internet
connection. Possibly via a cell phone data connection. It does not appear

... I have a lot to learn on this subject! If I?m understanding correctly,
while it?s true that the station who uploaded KD4KOY-11?s info to the APRS
network was indeed TCPIP-only, I was under the impression that he received
the packet FROM the balloon via radio.
For example, the most recent contact is pasted below. Am I correct to
assume that KD4KOY-11 transmitted via radio and was digipeated by W4YSB and
iGated to the greater APRS network by WD4LSS (who used an internet
connection to do so)?
=========================================================
KD4KOY-11>CQ via W4YSB*,WIDE2-2,qAR,WD4LSS (good)
WD4LSS>APU25N via TCPIP*,qAC,T2TEXAS
=========================================================
Understanding all this is of particular interest to me because this is
exactly how I iGate packets digipeated via the ISS... I receive via RF (an
SDR on a Rasp-Pi) and use an internet connection to forward what I receive
to APRS after it?s decoded by the direwolf application.
Thanks all.

Since APRS is indicated, that would be 144.39 in this part of the world but
it could also be using something like 145.825 and be picked up by iGates
configured to receive the previously-used ISS packet traffic on VHF.

Somehow grabbed the wrong callsign. KD4KOY-11 looks like it is on 144.39.
My apologies.

I only just discovered an email in my spam folder from the principal
investigator of the Roscosmos International Space Station
"Shadow-beacon" Experiment indicating that the experiment series has
concluded. Valentin Strashinskiy has requested that experiment
participants provide corrected names and addresses for certificates of
participation from Roscosmos. See the email below, and check your spam
folder if you didn't receive the email.
Hopefully, we will see more such opportunities for amateur radio
operators in the future.

Dear friends!
I hereby inform you that the space experiment "Shadow-beacon" on the ISS
is declared completed after expiration of the planned timing of its
implementation.
There were conducted six series of experiment sessions, the total number
of participants was about one hundred of the 31 countrieswith the
largest representation from Russia - 21, Ukraine ? 13, US - 12, Japan -
7, France - 5 and the UK - 4, the total number of submissions ? more
than 200. The results are reflected in the abstract and in the
presentation of the report released in 2014, see the links in chapter
?Experiment results? at our site
http://knts.tsniimash.ru/shadow/en/Default.aspx.
The full text of the alert is placed in section "News", where also
presented is the full list of participants, reporting on their
observations in any sessions of the experiment. As stated on our
website,you will receive honorary certificate of participation approved
by Roscosmos.I ask you to provide your name as you would like to see in
the certificate and the mailing address as it needs to be placed on the
envelope. Also make please a brace for my address vastra@xxxx.xx
<mailto:vastra@xxxx.xx>. Note that your personal data is only accessible
by the site administrator.
I sincerely thank you for your interest in our project and personal part
in it.
Would hope that your interest in space exploration will attract you to
participate in any future projects similar to the "hot" experiment
"Shadow" with plasma injection, if there is the necessary technical
capabilities and will take appropriate administrative decisions.

I am going to send up a few micro beacons (milliwatt HF CW transmitters)
probably using Walmart balloons and thin wire as the active antenna/payload
string.
The CW beacon RF module is a really simple oscillator that drifts a certain
amount with temperature - that way I can tell how cold it is based on the
received frequency from on the ground. An ATtiny or something similar will
probably be used to keep the beacon legal and send out CW every 10 mins to
break the carrier.
So the whole RF module and beacon is extremely light, basic
transistor/crystal oscillator + ID chip so I don't have to worry about
recovery. The only consideration is the battery. I will probably have
something operational between 3 and 7 volts, so I am thinking about just
stringing a few watch batteries together. Is there a certain recommendation
for low temperature operation miniature batteries? I need to make this
payload as light as possible.
The goal is the cheapest Amateur Radio balloon project where recovery is
not a worry. Signal strength reports across the country as well as wind
predictions can get a good idea of where the balloon travelled. I can then
match this data up with the daily National Weather Service launch data to
determine how high my balloon went based on temperature.

Thanks for the reply Richard,
I have updated the doppler.sqf file, which is correct.
So maybe that's what I'm missing, that it's tied to another object, and it's
just not broken out yet in the NASA tls file yet.

Skyler, you may want to look at various li-po batteries at your local hobby
store. You may find more capacity at the same or close to same weight as
watch batteries

Subject: [amsat-bb] High Altitude Balloon micro battery reccomendation
I am going to send up a few micro beacons (milliwatt HF CW transmitters)
probably using Walmart balloons and thin wire as the active antenna/payload
string.
The CW beacon RF module is a really simple oscillator that drifts a certain
amount with temperature - that way I can tell how cold it is based on the
received frequency from on the ground. An ATtiny or something similar will
probably be used to keep the beacon legal and send out CW every 10 mins to
break the carrier.
So the whole RF module and beacon is extremely light, basic
transistor/crystal oscillator + ID chip so I don't have to worry about
recovery. The only consideration is the battery. I will probably have
something operational between 3 and 7 volts, so I am thinking about just
stringing a few watch batteries together. Is there a certain recommendation
for low temperature operation miniature batteries? I need to make this
payload as light as possible.
The goal is the cheapest Amateur Radio balloon project where recovery is not
a worry. Signal strength reports across the country as well as wind
predictions can get a good idea of where the balloon travelled. I can then
match this data up with the daily National Weather Service launch data to
determine how high my balloon went based on temperature.

Thanks for the reply Richard,
I have updated the doppler.sqf file, which is correct.
So maybe that's what I'm missing, that it's tied to another object, and it's
just not broken out yet in the NASA tls file yet.

What file are you using? It shows up in the NASABARE.TXT file. Due to it
having been launch as a secondary payload with a classified primary payload,
it won't show in most element sets.

I have searched up and down through the Keps and can't seem to find AO-85 or
Fox1 in there anywhere.
And because of that, I can't find that in SatPC32 of course.
Is there some other name that it shows up as in the keps file that I have
missed somewhere?
Many thanks,
Walter/K5WH
