MarexMG recomendations for SSTV on ISS

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.

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%)
Record the temperature of the heat sink at the Antenna junction.
