[amsat-bb] AO-85: Tone or no Tone for SSTV

two questions:

According to Amsat website, 67Hz tone is required for a couple of seconds
to activate repeater.

Once the repeater is activated, does it still require the tone every couple
of minutes to stay on, or does it only start the timer after normal
("un-toned") activity stops?

Will constantly sending the tone during SSTV Tx mess with the SSTV Rx?
I'm planning on eventually trying my own image, and want to be sure I don't
waste 36 seconds of valuable airtime.
