Ham Radio Beepers? (paging)

I recall playing with some discarded pagers and decoding POCSAG right before I went to Radio Shack and bought the Technician-Class study guide.

I've been trying to swing a deal on a 900 Mhz Motorola Nucleus transmitter. Why? Its the cheap big iron of the day, thats why. Its also 500W on 900Mhz, and cheap! Heck, if the pieces for a 900 Mhz repeater fall in my lap, (freely or cheaply) why not build one?

But what about actual paging on Ham Radio frequencies?  We are nerds, aren't we?   ;)
