Thank you, I found an Ubuntu .deb package that installed into Debian 12. 
Exactly what was needed.

shadow from the sun as people use that to check antenna pointing.

Re: [Gpredict-discussion] Gpredict-discussion Digest, Vol 84, Issue 1

[Nigel A. G. G8IFF/W. <ni...@ng...>]

You can't track planets and moons with most satellite tracking programs as the planets are in orbit around the sun and not the earth. There are no TLEs for planets.
You'll need to find a program written specifically to track planets.

Re: [Gpredict-discussion] celestial objects

[zed b. <chu...@gm...>]

The planets orbit the sun not the earth. Therefore they do not have tle's.
The tle describes an objects earth orbital parameters.

[Gpredict-discussion] Frequency Correction.

[Vince P <ve...@ya...>]

Hello everyone. 
Does any one know which file I can edit to change the satellite frequencies. When I change it manually in the radio control it reverts to the default incorrect frequency when the satellite is selected again.  

Using gpredict for windows. 

Thank you.

[Gpredict-discussion] Solar Terminator and Global shadow

[Jack F. <jcf...@me...>]

In regards to Gpredict 2.2.2 or later.

How do you get the Solar Terminator and Global shadow to display on the 
map view?

When I go to Preferences --> Map View
There is a list of items where the color can be changed. Included in the 
list is Solar Terminator and Global shadow. When I set either one to 
something like red and the opacity set to the maximum they don't appear 
on the map view.

What am I missing here?

Thanks.

The "L" is activated; and so do I expect that Uplink(TX) frequ. should

(_please see pictures_)
If I search for a station to call, I turn the RX(Down) frequ. and in the

*2)* _every 2 seconds the radio is switched to TX for a short moment_. 
and this again and again. until I swich off the "Start" Button.

When I remember in Hamlib3.3 the Uplink(TX)-frequ followed the 
Downlink-(RX) frequency immediately.

Currently Gpred is for me NOT usable to make a QSO on a satellite.

What is the (my) mistake ?

Re: [Gpredict-discussion] FT-847 not transceive

[Black M. <mdb...@ya...>]

There's a special option in rigctld that allows you to "twiddle" the knob.
add this to your rigctld command line.
--twiddle_timeout=2
Where the value is in seconds and once you start moving the knob no frequency changes by gpredict will be done until you stop twiddling for that # of seconds.  Two seconds seems to work for most conditions as you dial in what you want...maybe you want a bit longer though.  The Doppler will shift more when you stop twiddling the longer the timeout.

Re: [Gpredict-discussion] New Feature Request (And new subscriber :)

[Alexandru C. <oz...@gm...>]

Hi Al,

Thanks for your mail and the thorough description of your use case. I
always enjoy reading about how and under which conditions Gpredict is used
and it also gives me a better understanding of the use case scenarios.

You are not the first one to ask for enhancing the data interface and
provide tracking data in a more versatile way. I have now created an issue
in our issue tracker to keep track of progress on this item, see
https://github.com/csete/gpredict/issues/248 . Unfortunately, there are
many items on the todo list and have have very little time to work on
gpredict at the moment, so I can not come with any assessment about when
such interface will be implemented.

Cheers
Alex OZ9AEC

[Gpredict-discussion] New Feature Request (And new subscriber :)

[mudhwk <mu...@gm...>]

  HI Folks,

  Thanks for adding me to the list.

  I am a new "serious" gpredict user, after having poked around with it on
occasion for a couple of years casually.

  By way of background,  back in the 90's (Before hamlib),  I wrote an
FT-736r control program called FT-7361,  along with a tracking antenna
program called prrietrk.  It wasn't pretty,  but it did a lot of convenient
stuff reasonably well.

  When used in conjunction with Wisps' EasyComm interface,  it automated
all aspects of pacsat operation, while allowing me to automatically
schedule flipping tover to the local repeater at commuter hour, and
pointing my beam at whatever repeater I might use etc.

I happily wore out several rotators using this automation 24x7 for a
while,  then got away from it.

I'm recently back, and on a whim dragged FT-7361 kicking and screaming from
its Windows 3.1 origins to mostly running on my windows 7 desktop as an
easy way to get on the FM satellites.   For antennas, I've built a switched
array of small yagis computer controlled via a modified Ameritron RCS-10
antenna switch.  The antenna array is not super high performance but is
adequate for FM sats, and has no moving parts to wear out.

  This morning I threw together a python hack to impersonate rotorctl  and
was delighted to see gpredict seamlessly drive my antennas!

  Reliably controlling the FT-736r is more troublesome via hamlib,  and
although I'm still on the learning curve,  I can see some limitations that
I'd like to avoid.

Given the limitations of the FT-736 cat interface, something a bit more
tailored to the radio's quirks is probably necessary,  hence my desire to
resurrect FT-7361 as the "master of ceremonies" that drives the radio and
chooses what to track etc  (In particular FT-7361 can manage a Mode B <->
Mode J band swap if a third band module is present, which is hugely
helpful. )

  Sorry for this being so long, but I wanted to explain the use case a bit
before  getting to the  point:

  Would it be possible in terms of a new feature request to ask for
Gpredict to include a "wsjt-x style"   UDP Broadcast facility that would
broadcast an Easycomm protocol string with the currently tracked  satellite
name,  az/el/uplink/downlink frequencies and modes as well as the scaled
doppler value?

  With this,  I could directly tie FT-7361 directly to gpredict,  and
bypass hamlib altogether.   It's not a solution for the masses, to be
sure,  but I think that in addition to myself, this would be very
beneficial to a lot of the other homebrewers.   Hamlib is REALLY COOL for
commercial  equipment,  but it doesn't lend itself real well to off the
wall homebuilt setups may have different communications needs.

  Thanks for any consideration (and for a cool linux based tracking
program! :) )

Re: [Gpredict-discussion] Proxy server setting

[Jaime R. <ja...@ro...>]

Hello,
I personally don't use today the proxy settings but I think it os a good
feature that can allow some users to use GPredict in special environments
where there is no direct Internet connection.

I think it really makes sense to keep it if it is not disturbing too much
to the restnof the code :-)

Thank you for GPredict, it is a great software!

Jaime, EA4K
