Just realized that my Icom R-7000 with the NTSC TV Adapter should be able to receive these signals. I've got a nice loop Yagi for 900 MHz as well sitting in the attic. Just sold the receiver on Ebay, but not shipping it until Monday morning--so may have to try to receive a pass over the weekend. Sounds like fun!

I sold the R-7000 thinking that I'd simply replace it with a FunCube Dongle Pro at some point. Never dreamed that I'd have a nearly immediate use for my old standby. Ah, well.
