The movie below has SSTV pictures I received and audio from back in 2008. After a number of tries I made a contact on 8/29/10 2230 UTC to CDR Wheelock NA1SS on ISS. I used 145.800 rcv 144.490 xmt on my Yaesu FT-2500 with low power to Arrow J-Pole at 14 feet. I had the frequencies on two different channels and switched between them.
You can use the Heavens Above on-line tool to know when the ISS is above the horizon. Be sure to set your location. Give it a try. Your ordinary 2 meter FM rig will handle it.
