Thanks Frank for the answer,
But no... the signal power down was in the middle of the second picture... the SSTV audio was still barely audible in the noise floor of one of my receivers... and disappeared just as expected at the end of the 3 minutes of tx just a few seconds after LOS
I searched for that pattern (3 on/3 off) on my full pass audio recording...
Never mind, just curious here...

Pavel,
The ISS Kenwood D710 is being duty cycled 3 minutes on and then 3 minutes off to minimize overheating. That is why you heard no signal in that period.
Thank you for your interest in the ARISS program and AMSAT (via -bb).

Just received 2 pictures #6 and #? 01/feb/2015 ~0031z here in Camag?ey Cuba, FL11aj
The start of the picture was just a few seconds of AOS, #6 with medium quality (jpole and HT whip antennas), unusual strong signal, in the middle of the second photo the signal dropped to the noise...
Three receivers here (RTL-SDR + base kenwood and baofeng UV-5R) and power down was noticed on the tree and stanle...
Just curious... does anyone have a explanation on that?... there was about 3 min to the LOS from a 9 min+ pass and the signal just dropped and stayed that way until LOS, not fadding...
Maybe a solar panel get on the path of the signal?
