Help needed in Fine-Tuning SSTV on ISS

ISS Amateur Radio

Miles WF1F of MAREX-MG has requested help in the fine tuning of the Amateur Radio Slow Scan TV (SSTV) system now operating on the International Space Station (ISS).

In an email on the AMSAT Bulletin Board (AMSAT-BB) he writes:

We need your help in fine tuning the SSTV system on ISS.
Here is how you can help.

VOX Delay:

There is an intermittent problem with the VOX box that controls the transmitter switch on the radio. When the VOX hears sound coming from the Laptop, it will turns on the D700 Transmitter. When the sound stops, the transmitter should shutdown in 2-3 seconds.

We need you to listen to the end of the SSTV signal and time the delay.
