[AMSAT-BB] Re: SatPC32 problem- Access is denied

2 Jan 2022

      I fixed my doppler frequency issues with my 9700. What I had to do is 
run PstRotator as a standalone APP to control the rotor, and use SatPC32 
to control just the radio. What is strange is that the  tracker , sat, 
SatPC32, function used to work flawlessly in PstRotator until about a 
year ago. So somewhere during the time I was up north for the summer the 
PstRotator program was changed and the function doesn't work reliably 
anymore. But it does work with my 9100. Anyway I'm going to run both 
radio's with the separate rotor and radio APP's. It's a little 
inconvenient, but not a big deal to do so. I also posted this issue to 
the PstRotator site and received no reply's.

I have a similar problem with my 9700. I have a 9100 along with the 
9700. The problem is only with the 9700. It also only happens here at 
my Florida home. The 9700 works flawlessly at my QTH in NJ It also 
works 100% when I use my 9700 for FD, and portable operations from the 
tailgate of my vehicle. The only time I experience SatPC32 drop out 
issues with my 9700 is just here at my winter home.
What happens is I notice I'm not doppler correcting, so I have to 
close SatPC32 and power cycle the 9700. This happens about 50% of the 
time and only while operating on linear sats.  It's been an issue for 
about a year, I've owned the 9700 for about 2 years.It worked fine 
here for about a year. I even  reloaded the PC's operating system when 
I upgraded to solid state drives. Problem remains. I  swapped USB 
cables between the 9700 and 9100 and the problem follows the 9700. I 
do use a different rotor system here, and AlfaSpid controlled by a 
Green Heron RT-21, and PstRotator. Up north I'm using a Yaesu 5500 
with a LVG box.  I'm convinced it's something to do with the 9700 
itself. This is sorta driving me crazy as I can't figure out what the 
problem is. I'm very interested in trying any suggestions from this 
thread...

You're right: running the program under my Admin profile is not the 
same as "Run as Admin", and I'd forgotten to try that. Intermittent 
problems can be annoyingly slow to show themselves, but I'll go down 
that rabbit hole and start over.

In case it isn't the cable, have you tried running SatPC32 as 
administrator also?

I feel your pain, Larry. I have seen the very same thing happen
on my end a bunch of times; it doesn't happen regularly, but it
happens enough that I have to keep a close watch on SatPC32. I'm
a full time RVer, so all of my operating is portable.When I
operate from what I consider my home grid (EM70), it's generally
not that big of a deal, but it's happened during roving trips too.

If the truck is disconnected from the fifth wheel, I'll set up on
the tail gate; otherwise, I'll use a small folding table from
Wally Worldand set up on that. My IC-9700 is controlled usually
by an Asus netbook but sometimes by an HP laptop; both are
Windows 10. I've used a variety of cables, but for the last
couple months have been using a Tripp Lite cable with ferrite
chokes on both end.

My thinking was that the problem is RFI related, so I've taken to
keeping the laptop separated from the rig by as much distance as
possible and in the opposite direction from the current satellite
pass' general azimuth. After I started spacing the rig and laptop
farther apart, I don't see the problem occur as much, but it
still does occasionally.

Most times, I discover SatPC32 has crashed because I hear my
downlink signal "take off" and I start sounding like Donald Duck.
A quick glance at the Tracking menu invariably shows that the Cat
control has become disabled, i.e. "C+" has become "C-". My
eyesight isn't what it used to be, so spotting that change gets a
little tricky since the laptop is farther away from the rig. I
get the "Access Denied" message when clicking the "X" too.
Closing the program with Alt F -> Q and then restarting it
usually does the trick, but sometimes I have to do a full laptop
reboot as well as disconnect and reconnect the USB cable. One
laptop has two USB ports and the other has three, and I've seen
the same thing happen on all ports. (Thankfully, the port
assignment doesn't change when I move the USB cable around, but I
keep a watch on that too just in case.)

So far, I've noticed these symptoms happen only on U/V birds, not
V/U. Also, I've seen this happen regardless of when I'm using my
User account or Admin account.

I'm interested to see what you find out. I'll let you know if I
figure something out.

Subject: [AMSAT-BB] SatPC32 problem- Access is denied

This problem has occurred a few times during a pass. SatPC32
stops working (I can see its not updating the frequencies) and
whenever I click the tone control (T0, T1) I get the message
"Access is denied" and the Countdown window dissappears. If I
click OK on the message popup, the window reappears.  It gets worse;
In order to restore operation meaning to get doppler control so I
can make a sat QSO, I need to restart SatPC32 but when I click
the X, I get the error message. I must click File, Quit.
By this time, the pass is over.  Restarting SatPC32 does restore
normal operation.
This problem is intermittent. Most of the time, SatPC32 works
well with my IC-9700. The PC is running Win10.
Do these symptoms point to a known issue or do I just reinstall
everything?
