It does look as though you are both connecting to DIO2: "When the RFM69 is used in continuous OOK mode, the signal can be read from the RFM69 DATA (DIO2) pin."
What I'm still not clear on is: is DIO2 presenting you with an analog value, or purely a binary value HIGH-LOW based on a threshhold that you set? I do realize it says DIO2, not AIO2, but what really happens isn't constrained by silkscreen alone. In looking at his plot of the the Oregon Scientific V1, it does seem as though he's reading an analog strength value (what he calls "raw RSSI"): "...it is easy to record the raw RSSI and OOK data from a RFM69..."
Maybe it's just me, but I find it a lot easier and faster to read code when there's a high level description as to what's going on, and then try match that against the code, than it is to read code purely bottoms-up.
