Seems to just suggest that you might not get as good range with 433MHz
due to it requiring a larger antenna. Also appears that you can
software configure the 868 watch for 915 and vice-versa.

I ordered the 868MHz variant as this is the frequency used by the
RFM12B modules that come with JeeNodes. I have one of these waiting to
be assembled, and also a spare module to use with a Nanode, which is
also waiting to be assembled... Hoping that they can be made to play
if only via on-off keying and at low bitrates.



PS. Amusing that someone commented on the wiki that it'd be nice it if
had GPS. At under $50 be nice if it had an OMAP processor and booted
Linux too!
