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


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?
