I guess there was a time when manual tuning was the in-thing, even though
everyone would drift off the end of the bird's pass-band. However, speaking
of the 21st century, I've always considered computer based Doppler tuning as
a minimum in my operations with SSB birds.?
Technically, each station should be using ONE frequency pair "at the
satellite".? In fact apps like SatPC32 and HRD et al, have been designed
precisely for this.? Someday a dedicated Arduino or PIC based dongle may
replace the need for a full fledged PC to do this.?

In case you missed it. Radio astronomy news.
Greg N3MVF
(CNN)Far outside our Milky Way galaxy, something is causing repeating short
bursts of radio waves to be released into space. Scientists have recorded
the second repeating fast radio burst to be discovered, according to a study
published Wednesday in the journal Nature.
The finding was also presented at the 233rd meeting of the American
Astronomical Society in Seattle.
These radio bursts are only millisecond-long radio flashes, and such rapid
bursts themselves aren't rare in space.
But this is only the second one that has been found to repeat. The mystery
about why these bursts happen and where they come from continues, which
always spurs believers to think that advanced extraterrestrial civilizations
are creating them.
The first one, deemed FRB 121102, was discovered in 2015 by the Arecibo
radio telescope, and it was revealed in 2018 that the bursts release an
enormous amount of energy.
What's sending mysterious repeating fast radio bursts in space?
This new repeating fast radio burst is called FRB 180814.J0422+73 and was
recorded six times coming from the same location, 1.5 billion light-years
away.
This is one of the very first detections made by the new Canadian Hydrogen
Intensity Mapping Experiment, or CHIME. The radio telescope was still in its
pre-commissioning phase and operating with only a small amount of its full
capacity in the summer of 2018 when it detected this and 12 singular fast
radio bursts.
And although this new detection doesn't solve the biggest mysteries
surrounding the radio bursts, the researchers who recorded it believe that
other repeating fast radio bursts will be found -- which could allow them to
figure out where they originate.
"Knowing that there is another suggests that there could be more out there,"
said Ingrid Stairs, a member of the CHIME team and an astrophysicist at the
University of British Columbia. "And with more repeaters and more sources
available for study, we may be able to understand these cosmic puzzles --
where they're from and what causes them."
One hypothesis is that powerful astrophysical phenomena are causing them.
The first repeating fast radio burst was recorded at a frequency of 700
megahertz, but some of the bursts CHIME recorded were as low as 400 megahertz.
"[We now know] the sources can produce low-frequency radio waves and those
low-frequency waves can escape their environment, and are not too scattered
to be detected by the time they reach the Earth," Tom Landecker, a CHIME
team member from the National Research Council of Canada, said in a
statement. "That tells us something about the environments and the sources.
We haven't solved the problem, but it's several more pieces in the puzzle."
The low frequency of this new detection could mean that the source of the
bursts differ. "Scattering" was detected in the fast radio bursts, which is
a phenomenon that helps determine more about the environment surrounding the
origin.
The CHIME team believes this scattering is indicative of powerful
astrophysical objects at the source of the bursts.
"That could mean [the source is] in some sort of dense clump like a
supernova remnant," team member Cherry Ng, an astronomer at the University
of Toronto, said in a statement. "Or near the central black hole in a
galaxy. But it has to be in some special place to give us all the scattering
that we see."
And if CHIME was able to make these detections before it was even fully up
and running, the researchers are hopeful that the new radio telescope will
help them find answers about these mysterious signals.

Eric:
MacLoggerDX stores log data using SQL data-base-like format.
The logging software also has an ?abbreviated entry? "contest mode" in
which minimal fields of data are typed / input.
That reduces the per-QSO typing but still gets legacy QSO data into your
log.
If it?s easiest for you to move your log data into a database, MacLoggerDX
can easily import it.
Or if it?s easiest to type the data directly into the logging program,
that method works well too.
Here?s another possible alternate way:
Select a trusted family member/student going to college who needs a little
extra cash. Hire them (per 100 QSOs)? to type the data in with their pay
based on the accuracy of the resultant data they?ve input.

I did it using Fast Log Entry.

It is still a laborious process, but FLE greatly reduces what you have to
repeat.
I have ka0yos (old call) entries on LOTW back to RS-10 and AO-10.

The TLE data depends on the exact positions of each item. Positions are
compromised when copying documents.
Such damaged TLE data are not in sat programs as GPredict) processed.
The repair is simple. Just compare the positions of dots and dashes in
TLE data? and move items to the correct positions.
Already for FOX-1D I wrote a TLEdoctor program that can display flawed
positions and can easily be corrected by comparing with the template.?
After repair,? GPredict data can be uploaded and we can take all

Hi all,
Are we waiting for a reset on MINXSS-2, if so, when is that due, or is
there other issues..?
regards
John

For those of you with an SDR dongle, for example the Funcube Pro +, how do
you protect it from not being damaged by TX energy? I?m thinking of hooking
mine up to the 70cm antenna in my M2 LEO pack while I TX on the 2m antenna
and was afraid I?d overload the SDR. I see folks using them for their RX on
linear birds, so I?m just wondering how you have them hooked up.
Thanks in advance for your advice.

Hello All AMSAT members in worldwide,
Before the New Year 2019 I 'm Tanan, HS1JAN and Khun Chawalit, E20KEW
along with Khun Krisada, E21EJC visited Prof Dr. Suwat, the Knacksat
Project Leader, and Dr. Pongsathorn, the Knacksat Project Team Manager at
the King Mongkut Institute of Technology North Bangkok (KMUT-NB) to enquire
about the status of the Knacksat satellite following its SSO-A launch by a
Space X rocket on December 3, 2018.
Due to problems with the Space X rocket, the launch had been postponed
several times with the Knacksat satellite being kept on hold and the
satellite's batteries may have become depleted by the time the satellite
was finally launched by SSO-A. When the deploy switch has been working for
about 30 minutes the VHF/UHF antennas are deployed with heat from the
nichrome wire. https://www.facebook.com/knacksat/videos/818456401588168/
This creates a need for high-voltage electricity which may be the reason
that Knacksat satellite batteries had lower power than normal. If this were
the case Knacksat satellites would then enter "Save Mode", or a sleep
state, in order to charge the battery and to await orders from the HS0AK
Ground Station.
We are confident that the Knacksat satellite is still in a state of sleep.
The Knacksat team expects that it may take up to many months to charge the
battery to get to the original energy level. Hence, I would like to ask
amateur radio operators in the AMSAT group to help the Knacksat team as
well.
The Knacksat team needs urgent help in receiving reports of the CW beacon
signal on the frequency of 435.635 MHz because the Knacksat satellite will
send the CW Beacon signal when the solar cell panel receives enough
sunlight to charge the battery. Hence, there may be a signal from the CW
beacon with the power of just 10 - 100 mW from the Knacksat satellite at
any time.
The Knacksat team has prepared rewards for anyone who sends them details
with a signal report received from the Knacksat satellite including QSL
cards, and Knacksat shirts, etc. Anyone who copies the satellite should
please send an email to knacksat@?????.??? or enter a report at this
website: https://knacksat-26d23.firebaseapp.com. Details can be found at
http://www.knacksat.space/
Since the satellite was launched about one month ago only two persons have
received signals of the CW beacon and the signal has been very weak such
that the CW could not be fully copied while the telemetry could not be
fully decoded. Therefore, we would like to make an urgent request for
amateur radio operators to study the information below and to please get in
touch by email with knacksat@?????.??? to help the Knacksat team.
1. The need is for an amateur radio station with an antenna with the EME
level of gain to help. The UHF frequency at 435.635 MHz requires an antenna
with a very high gain to receive the very weak CW beacon signal.
2. The need is also for an amateur radio station equipped at the EME level
with a high-gain VHF antenna to try to send the sound (MP3) for command
change mode uplink VHF frequency. that will wake up the Knacksat satellite
from being in Save mode.
Therefore, if any AMSAT member knows of anyone or can help or who can
co-ordinate efforts to contact or is capable of receiving signals from the
Knacksat satellite, could they please get in contact with the Knacksat team
as quickly as possible.
Thank you in advance for helping the satellites of Thailand. In the near
future and not later than the second quarter of 2019 (Q2) the JAISAT-1
(?Joint Academy for Intelligent Satellites for Amateur Radio of Thailand.?)
satellite will be launched into space and we will keep you informed of
progress with further news.
With respect
Tanan Rungseeprom, HS1JAN
