Is there any uplink SSTV or is this downlink only?

To prevent crew overload, the Uplink will not be published at this time.
Schools are using Odd splits, etc.
Uplink may not work at this time because of a last minute computer change. The SpaceCam1 software did not incorporate the Auto Sync software at the time it was developed. The Sync needs to be manually set for the Uplink and Down link on SpaceCam1. As soon as we have the opportunity to test on a terrestrial version of that computer we can figure out the Sync value and enter it into the ISS computer. Any images set up to ISS today would not be usable.
I am trying to work through the Red tape to arrange the test.

Thank you for the reply. I just wired a simple patch cable from my APRS radio spk jck to the line in on my #2 Soundcard. (I have 3) I am located EM84 Lavonia, GA I will leave MMSTV running 24/7. I will cross my fingers.

The SpaceCam1 SSTV program has the ability to run 5 different flavors if SSTV imaging formats, including: Robot-36, Robot-72, Scottie S1 and S2 and Martin M1
If the crew is using the system Manually, they may use any format they wish. However if the SpaceCam1 automatic Slide show mode is used, we need to be concerned Thermal issues with the regarding transmitter.
We do not have convection cooling in space! All electronics in ISS will run hotter than they would on Earth. The Kenwood TM-D700 has not been modified to operate in Zero-G, without Convection cooling!
Therefore the official recommendations from MarexMG are the following:
Run the Slide Show mode at 5 minute intervals more. Set the TX power output to Low or 5 watts. Set the Image format for Robot-36! (reduce the duty cycle to 15%) Do not run Unattended until we have established the stability of the VOX and set the Audio settings to prevent continuous carriers. Record the temperature of the heat sink at the Antenna junction.
