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.

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.

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?

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.

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.

My apologies if this has been covered already.
Have you double-checked what you have designated as your home location?
QRZ.com shows this location info for you:
Latitude 43.610010 (43? 36' 36'' N)
Longitude -90.082150 (90? 4' 55'' W)
Grid Square EN43xo
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.

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

Not Satellite related, but people often ask about any RFI from my solar
arrays at home. Interest stems from an RFI issue in April QST and my letter
in Sept 2016 QST.
Well, FINALLY, the jury is in. For the first time since installing solar, I
finally got all my full-sized dipoles up in the air again. And listened with
the arrays on and off.
Yes, I have inverter noise about 12 dB above the noise floor every 38 kHz on
80 meters,. But couldn't really find anything on 20 meters. I did not do a
thorough search, but enough to finally say, "yes, there is some noise..."
I post this because my 16kw of arrays are conventional series string arrays
and much quieter than the "optimizers" on every panel all over the roof
noted in the April QST article. I always thought my string array was quiet,
but now I have some data noted above. This could easily be fixed with some
clamp-on ferrites down in the basement on the wires going into the
inverters...
But for my rare HF operating, the solar AC disconnect switch is about 3 feet
from the kitchen door. Easy enough to pull if I want HF silence. I could
also install a 40 amp disconnect relay from a switch in the shack... But
with my rare operating style, I'll probably do nothing. Of course it is
perfectly quiet at night ;-)
It took me 6 years to get around to this test, so don't hold your breath
waiting for me to add some clamp-on filters to the inverter wires and see
what that does.

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?

Another one of the reasons I left my old QTH was all the homes around me
had solar with many different styles and HF RFI during the day was awful
but I had no switch to shut them up.

Thank you to all for your responses.
I've been out of town, so I haven't had the chance to check other satellites
besides FO-29 (and AO-73, but that one is always shifting around due to
issues with the satellite). I'm going to try more experimenting with Pedro's
Doppler.SQF line and Erich's correction procedure. Yes, I've checked
location and time, and they are all as they should be.
I do have a theory that something has become corrupt in the program files
themselves, and I'm going to try a new download and clean installation of
SatPC32 to see if that fixes things.

Hello Mark,
try the following:
Track a FO-29 pass and find your signal using the "Upl. Corr." up/down
controls in menu "CAT". Fine tune the uplink for best audio (best around
the middle of the pass). Then click the "Change/Store Data File" in
menu "CAT" and in the little window that opens click on "Upl.
Correction". That will save the correct uplink frequency. That is easier
and more reliable than to enter observed frequencies manually in
Doppler. SQF.
At the next program start you should immediately hear your signal.
Little deviations (100 ... 300 Hz) may remain due to temperature
differences at the sat or the radio. You can easily correct them using
the +/- keys of the numerical pad with a few hits in steps of 100 Hz.
(The keys work only if SatPC32 must be the active program - blue header
line).
73s, Erich, DK1TB..
