Hello
Some enhancements are coming to satreporter
There will be a new main table sorted by last heard to give you an idea of
what was heard in time
The uptime an availability has been very good
I might setup a production and live machine to make interruptions seamless
Let me know if any other satellites need to be added
I can also do email alerts for satellites
I want also to do a daily report of APRS satellites
I have to rework the statistics

Hello
I used to make use of predict using scripts
Since then the raspberry pi and arduinos have come along
What LINUX satellite tracking program could be queried or send data about
Satellite elevation and angle
Satellite doppler frequency
I want to make a multi satellite radio and rotor control box with auto
update keeps
I want to use perl to do the hard work
I want an arduino or the Pi to do the doppler and rotator

I have an open source Java / tomcat web app that provides that and can make
it available.

The libastro library contains essentially the same tracking functions
that Predict uses internally.? It is available for most distributions.?

All of the above can be handled by an Arduino or compatible board that has a
wifi or Ethernet module. I did it with an Adafruit Feather M0 and TFT
feather wing. I started development on the auto update of keps from AMSAT
using a wifi version of the board. I had to pack all that stuff up when I
relocated out of Los Angles but now that I have to deal with winter I plan
to get back to some of these projects that are collecting dust. You can have
a look at one of my posts on twitter here

Andrew,
I wrote this a while back but it's still worth a look if you don't ind
using Python on your PI. Google code is gone these days but so many
others had forked the project that I didn't bother backing it up.

Andrew - If you can use Python, consider the pyephem module. It can predict
satellite passes, calculate azimuth/elevation, determine eclipse state, etc
based on TLE data. See http://rhodesmill.org/pyephem/tutorial.html.

I think I used predict for LINUX
Does that ring a bell ?

The VUCC Standings for October 2017 are improving in terms
of callsigns that have gone missing. AI6GS K7TAB N1AIA
and AK4WQ(EN34) are back on the list. This month I am listing
the previous months totals along with this months totals for
the ones that have changed. If you don't agree with what is
on the November 1st listing, please contact the ARRL DXCC desk
and make that known.

Congratulations to everyone who made the list this month.
This list was developed by comparing the ARRL .pdf
listings for October 2nd and November 1st, 2017. It's a visual
comparison so omissions are possible. Apologies if your
call was not mentioned. Thanks to all those who are
roving to grids that are rarely on the birds. They are

Subject: [wsjtgroup] Caution Urged in Using High Duty Cycle Digital Modes on
Satellites
Satellite enthusiasts planning to try FT8 or MSK144 via satellite are
being urged to use caution or possibly to avoid digital modes altogether
in light of problems being blamed on the modes? high duty cycle.
Stations have reported problems getting into satellite transponders,
even during favorable passes, which were traced to digital-mode signals
in the transponder passband.
AMSAT News Service quoted an AMSAT-BB post (full thread) by Matthew
Stevens, NJ4Y, who cited his recent experience with FO-29.
?Experimentation isn?t the problem, too much power is,? Stevens said.
?It?s bad enough on SSB, worse with CW, and killer on constant duty
cycle modes like FT8.? ? Thanks to AMSAT News Service
