No not sure. I think I was told they work without an antenna as well,
but I didn't look into it further. I assumed 'without antenna' means
there is some antenna on the module, but that's just a guess. Maybe
they don't even work 'without antenna'.

You mean the Radica IM Me device?
Where is the hacking going on? Any URLs?
You are saying HopeRF's RFM12 is based on Integration/Silican Labs IP.
Can you tell us more about this? Is this good or bad? :-)
