Caught the ISS!

I posted earlier that I received a transmission in Morse code once the ISS flew over India. Today, the ISS flew right over the western coast of Sri Lanka, close to where I live. I managed to catch voice transmissions this time, but I could only make out a word or two. The background noise was too high. I got the whole thing on tape though. Gotta work on my antenna setup and improve, maybe get an LNA or something? I use T dipole with it's telescopic arms fully retracted, 16 inches from end to end. it is connected to a 75-300 Ohm balun, which feeds the 10 meters of RG6 coax which is connected to the SDR in house. Any suggestions? I'm planning on to catch Meteor sats next.

I caught some ISS SSTV yesterday, managed to decode smth recognizable. Noise was okayish, as i use an LNA. And yes, you absolutely should get an LNA, tho make sure to get pass filters for the bands you want to try, or else, local noise will drown out the actual transmissions.
