Try looking between about 1275 and 1300 MHz. In the larger metropolitan areas, there is usually some FM repeater activity. You can find some SSB activity on 1296.1, probably mostly on weekends and in the evenings.
There is actually quite a bit of ham activity on 2304, and even higher bands, but most of that occurs during contests, and unless you have good antenna and an even better preamp you won't hear it.
