We have stored realtime, highres and wod since the satellite was first
turned on in the lab.
The plan is to make this available via a login to the warehouse and
allowing download of such correlations.
Please bear with us. My todo list is quite long :-)
I'm currently working on the highres for download.

I cannot seem to get the ISS portion of the program to operate properly with
1. Regular SatPC32 program works as it should
2. In ISS, I have CAT control (trigger on/off with C
3. SAT on the radio is turned off
4. In CAT, I can select the pair for the repeater and the downlink freg
will appear on the radio (VFO A) The initial freq in the program appears but
does not update further
5. Manual says "With the Yaesu FT-847 only use the 'TX' / 'RX'
controls of SatPC32ISSto switch
the radio to TX or RX, rsp.
Otherwise the VFO can't be tuned to the TX frequency
before the radio is switched to
Program is not displaying TX/RX buttons or controls nor am I
able to key tx with + or - keys on 10 key pad
6. FYI, there are no files shown in any o the aux files. (but, I suspect
that info is pulled from the main program)
I must have something set wrong. Any help appreciated

We did on PCSAT!
Caution to Satellite Builders: Be careful when using an EXCEL TREND LINE
equation for doing Engineering Unit conversion back to original units. It
was a big lesson for us back on PCSAT in 2001.
The problem is, generally, EXCEL displays trend line equations in a nice
GENERAL human readable form. For example, for our thermistors, the 3rd
order trend line equation to convert from telemetry count back to degrees
C was displayed by EXCEL as something like this: 2E-7 X^3 - 2E-4 X^2 +
1.804E-1 X + 2.379E2.
One would think one is getting a very precise to 4-significant digit
equation. WRONG. Notice the Cubed and Squared terms (which can be very
big at warmer temperatures) are only represented to a single decimal
digit(+/- 10%)!!! (2 and 2)...
When this trend line is used (as displayed), to give back our
temperatures from the incoming COUNT, the temperatures were way off!
The key is to make sure the trend line equation is displayed in SCIENTIFIC
format before you write it down and then try to use it. Then the first
two terms above are properly displayed by EXCEL as 1.544E-7 X^3 and
-2.069E-4 X^2. (instead of 2E-7 and 2E-4).
We catch this error in a lot of student's work...
There is an excellent article by Mark Spencer, WA8SME beginning on page 43 of the January 2014 QST.
It mentions that a limited number of complete systems will be available through the AMSAT Store. They
are not yet available, and we do not at present have a firm date when they will be in stock. Because
of uncertainty of the price and number which will be available, we are not taking advanced orders.
When we are ready to process orders, we will make the information public. Please do not call the
Following the great success of our preliminary versions of our CAPE-2
Ground Station Software, I have just released Beta Version 1.1.1, which
opens up the ability to send a new slew of commands.
New Commands are listed below.
- Update Clock
- Set Green Mode
- Send Text to Speech (Voice Options: Perfect Paul, Darth Vader, Big
Bob, Precise Pete, Richochet Randy, Biff, Skip, Alvin the Chipmunk, Robo
Robert, Goliath, and Gretchen)
- Operate Voice Repeater
- Send Emails via CAPE-2
I also made some design changes to the software to make everything much
more user friendly, and secure. I am also adding a few additions to the
Getting Started Guide on the software's
Please review the new information before diving in. We are most interested
in results from the email command at current. So please try to send
yourself an email from CAPE-2!
As always, please direct questions, comments, and concerns to me at
