I am really excited about getting back on the Birds after a 40+ year absence. I've done EME, MS, AU, and all sorts of weak signal stuff on 144Mhz. I've played the DX and contesting on HF. All has been fun, but none except for the EME has given the most happiness than the memories of playing with the birds in the late 70's
Now let me know, I can take this off list if members here want me to, But This excitement is quickly turning into disgust. To the point I'm just about to say screw it and forget about Sat work again.
I am in the need of help with prediction programs.
Man in the late 70's it was the ARRL bulletin with keps etc. and a Oscar Locator.
Now we got ultra cool software programs that all are incredible! Except for me, I can not trust ANY of them. I have been testing several to see what I will make my primary program. BUT...... and there always is a "BUT" isn't there? I can not say what one to "Trust" The four I have installed are... SatLookDown1_28 HRDSatTrack Orbitron SatPC32
Now of course they all use the same computer clock. And it is accurate to less than a tenth of a second.
Each one periodically ask to Up-Date the TLE's and I say "YES" and let them do it all on their own. I change NOTHING on where they get their data.
The run them.
The, SatLookDown1_28 & HRDSatTrack, both agree very closely. Almost to the second.
But the Orbitron, is off, WAY off. like 15 minutes off.
And the SatPC32 is even worse the sat is like 1/2 an orbit off!
Now the ones that agree also match the page
http://www.amsat.org.ar/pass.htm#
So my guess they are the ones showing correct data.
Now what to do about the other two. How can I make them show correct passes?
Remember I can take this off list if no one wants to read about this... Just let me know,

Joe,
I feel your pain.
Back in the Oscar 7/8 and RS10 (et al) days, all I had was a simple program written in BASIC for which I had to manually update the element sets and which only provided a prediction rather than a "real time" view. It all seemed so much simpler and to some degree more satisfying.
Skip forward 35 to 40 years and we have all these wonderful near real time "ultra cool software programs", multiple computer platforms and operating systems (Windows, Apple OS, Linux, Android) and the choices are many, the learning curve can be steep, and it is easy to get frustrated.
From your list I have only first hand experience with Orbitron. The one I decided on is not in your list - GPREDICT.
I quickly settled on GPREDICT because to me at least it was intuitive and useable on at least Windows and LINUX. Generally I leave it running on a Raspberry Pi 3 and a dedicated monitor showing the various Amateur and Weather satellites in which I have an interest. Predictions are always spot on. I typically hear whatever satellite I am waiting for within a few seconds of the indicated AOS.
To be fair, I also have own GPS disciplined NTP time server which serves precise time to all of my networked computers plus I run NTP on each computer on the network. I check them regularly to unsure that all are correct.
Keeping you computer's time correct is the first hurdle. Having the correct time to the a couple of seconds is more than adequate in this case and if you have in interest in something like WSPR then within a second is usually sufficient.
The next hurdle is to get your latitude, longitude, and altitude set correctly in the program of your choice. Latitude and longitude need to have the correct quadrant be it specified as N S E or W or + for N, - for S, - for W, and + for E, and as precise as you can. But this you already know given your experience with the other modes you have listed. Altitude is also important but needn't be that precise but ensuring the right units is, i.e. ft or meters as required by the program. But again, I think you are already aware of this. I am just being complete in my reply.
Once all of your configurations are set correctly, I can't see these programs all giving different answers. It is possible but the underlying math is pretty much all the same for each of the programs.
cheers, Graham ve3gtc

I run most of those programs without any problems. I even run old Instantrak under DosBox, and WISP32. This all runs on a 64-bit Laptop Windows 10 system. SatPC32 needs to have the correct coordinates put in. You have to make sure that the longitude and latitude are the correct polarity as well. On WISP32 I merely have to make sure they are west/east or north/south.
I would definitely check your system time and date as well as QTH settings. Insure the time displayed is correct based on your settings in regards to local or UTC. I find that all of my programs come within seconds are less of each other for tracking.

I use InstantTrack for antenna control and Satpc32 for rig control. I download the NASA.all tle into Satpc32 and then load the same file into InstantTrack and haven't experienced any issues.
You might find it necessary to restart Satpc32 after you download the tle file or make any other changes to the program.

I think to the 4th decimal point should be accurate enough? -90.0826 actual was -90.0825925 Same accuracy with Latitude.
As far as time goes, I use, a program called Net time. it runs in the background and is constantly monitoring the PC clock. http://www.timesynctool.com/ It is set to Up-Date the PC clock if it is more than 0.1 seconds off. Being Leary of internet lag, when i first installed the program I was constantly comparing it to WWV directly over the air, , and it was always spot on.
I would definitely check your system time and date as well as QTH settings. Insure the time displayed is correct based on your settings in regards to local or UTC. I find that all of my programs come within seconds are less of each other for tracking.
A second off would be an eternity for me. I run WSPR with zero difficulties, and they say you must be less than a second off for that.
Plus think even if I was what 5 minutes off. wouldn't all 4 programs show the same error amount?

You didn't show your latitude. It should be positive. For example I use -80.703 Longitude and 28.161 for Latitude for my location. Also, you should be able to confirm by the map showing your location with a "+" where it thinks you are at. Also, try Wisat32 to see if you have the same problems.
Don't know what else to tell except that SatPC works fine for me provided the QTH info, clock info and keps are correct. Maybe someone else on here with more knowledge than I on SatPC32 can help.

Hi Joe,
Nice you are back on chasing birds ! Hope you get along and enjoy.
Thanks! for your comments on http://amsat.org.ar/pass.htm.
This app keplerians are updated 4 times per day, so don't need to update, it should take your location, local time and timezone by itself, further new sats get automatically its way into the application since launched.
Pass should also work on all sort of browsers and Op.Systems as well as portable devices running android (smartphones, tablets, etc) allowing to work birds on the field.
If using win, you can try the executable version at http://amsat.org.ar/pass.exe that with driver http://amsat.org.ar/wispdde.exe should handle rotor and Dopplers.
Pass is a cooperative effort where many users had contributed to keep it simple and usable.
So, welcome to space, wishing good luck kicking the amazing tin birds we have nowadays.

My apologies if this has been covered already. Have you double-checked what you have designated as your home location?

I have never used Orbitron, but in SatPC32 this is how to set it:
Open SatPC32. Towards the top center of the window, click on Setup, then click on Observer. A small pop-up window will appear with the title "Observer Setup". The second item from the top on the left side of the window is "Station Grid Locator". Click on the 2nd value down in the center of the window, to the right of "Station Grid Locator". Now enter your six character grid square in the field on the right side of the windows. Your Grid Square is EN43xo. Then click on the button [Locator>Degs], then click on [Store]. I am not sure, but you may need to close and reopen SatPC32 for the change to take effect.

Yup Qrz useds the middle of the square. Here I am https://goo.gl/maps/4XW2NDTGNkq and http://i63.tinypic.com/2vmfsk9.jpg And on SatPC did all that, and in the demo you have to do it every time ya open it. so re-opening it won't help.
By the way gang! Thank You for trying to help!
My EME program was on of all thngs a Timex Sinclaire, and it worked perfectly he he he amazing isn't it?

And the SatPC32 is even worse the sat is like 1/2 an orbit off!
Now the ones that agree also match the page
http://www.amsat.org.ar/pass.htm#
So my guess they are the ones showing correct data.
Now what to do about the other two. How can I make them show correct passes?
Remember I can take this off list if no one wants to read about this... Just let me know,

Joe,
SatPC32 normally works perfectly, and is used by the command stations for its accuracy and reliability.
Something to check. Click on Satellites, and see what the source file is. nasabare.txt is a reliable one. Look down at the bottom, and see what the file date is. It should be current within a day or so. You will need to do the update manually with the Update Keps button, for each source.
73s,
Alan WA4SCA
