I got a USB dongle that seems to work under 1GhZ. I was really interested in analyzing zigbee. I think that's in the 2.4GhZ ISM. Any suggestions?

I'm also curious ... are these cheap USB dongles just receivers? Or do they have ones that can transmit as well (i.e. transceivers).

You definitely can get SDR transceivers but 1) they are more expensive and not (to my knowledge) 'dongle' sized, and 2) in most jurisdictions there are understandably licensing conditions required in order to be permitted to transmit on the amateur frequencies.

If anyone with experience on SDR transceivers has some input here, that would be great!
