No need for complicated radio stuff, just something that will receive 145.800MHz FM mode, and ANY possible antenna, not neccesary to be 2m stuff, ofc one can use WebSDR with 2m but it's more fun to catch the pics. Tried even Baofeng UVB-6 - working good at higher ISS elevation :-)
Here some pictures better or worse received during ISS flyby last days received on FT-817 and 7ele Yagi for 50MHz with MMSSTV software. For flyby prediction free ORBITRON soft was used but there's many tracking software on the web, and also websites dedicated to it, i.e ISSTRACKER
