Hi Fellows,
Chris has asked me to upload a new MSPE 2.00L module for WiSP32.
This version is designed to work with UO-36. UO-36 has a power
budget problem and will turn itself off when not required.
This version of MSPE will send a turn on request which will turn
on the downlink when it is received by UO-36. Once turned on,
UO-36 will transmit for approximately 15 minutes before turning
off again. This is usually enough time to download between one
and two megabytes of data at 38,400bps. The uplink is at 9600bps.
The April 2000 QST magazine has a fine article on UO-36 written
by Stacey E. Mills, W4SM.
The turn on feature is automatic. WiSP will transmit the turn on
request approximately every 45 seconds during a pass until UO-36
comes on the air.
Sometimes it will not come on due to a software override in the
satellite because of low power conditions. This usually will
occur at night, but sometimes happens during the day also.
You must edit the Windows 95/98 Registry to activate the turn on
feature. Please do not activate this feature unless you are
equipped to copy the 38400bps downlink of UO-36.
The Registry editing procedure is as follows:
1. From the Start button select Run, enter REGEDIT and click OK.
2. Highlight My Computer and backup your Registry by selecting
REGISTRY, EXPORT REGISTRY FILE. Name this export file and save
it where you can get to it again in the event you do something
to your Registry. If you do not feel comfortable doing this,
stop now and forget it until you can find someone who can do it
for you. If you mess up your Registry we will not have the
pleasure of seeing you on the satellites for a while.
3. Go to
My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WiSP\Satellites\UO-36
4. Highlight the UO-36 Key Word in the left pane of the window.
5. In the top menu, click EDIT, NEW, DWORD VALUE.
6. The name of the new DWORD VALUE should be changed to
"Tx Request" without the quotes.
7. Now with Tx Request highlighted, from the top menu select EDIT,
MODIFY and enter a value of one (1) in the value entry space.
Entering a zero again will turn off the automatic turn on feature.
8. Close the Registry Editor.
Now every time MSPE opens with UO-36, it will automatically request
UO-36 to turn on.
This version will be posted on the AMSAT WiSP ftp site and on UO-22
and KO-25 as MSPE200L.zip. Let me know if you have any questions.
73,
Roy -- W0SL

I modified Windows WiSP registry to send a "turn-on request"
of the 38k4 downlink as follows.
Start-Run
C:\WINDOWS\Regedit.exe
HKEY_LOCAL_MACHINE
SOFTWARE
WiSP
Satellites
UO-36(TIUNGSAT-1)
Right mouse click
New-Dword value
Change to "Tx Request"
Edit-Modify
Enter "1"
UO-36(TIUNGSAT-1)
Right mouse click
New-Dword value
Change to "Max Holes"
Edit-Modify
Enter "25"
Base "Decimal"
When I have done this WiSP is automatically sending a command
to turn on the satellite transmitter when the satellite comes
into view.
