You can use an app like "ISS Detector" to get alerts when the ISS is over; that one also has an IAP that will show you any amateur radio satellite that's over your head, as well as the uplink and downlink frequencies. (Last time I was listening to cubesat AO-92, my social "nerd antenna" apparently went up to about 1 MW transmitting and I ended up pointing into the clear blue sky a lot while explaining to interested random passers-by why people still use ham radio. :-))
