Yeah, those output numbers are typical of what I remember for all units except Decatur.
My Stalker II was 11 or 12mw when I got it 3yrs ago & have no idea what it is today. The majority of the time in use it's w/ the +12v cord when Testing to ensure max power out so it's within 3db of its big brother the DSR to near duplicate State Patrol (for detection distance purposes when testing friend's RDs) agencies using the DSR in NewEngland States.

I had no idea the Genesis II was only 5mw...wow. No wonder I hear complaints about sniffing that one out. Same goes for the FalconHR @ only 8mw.

One day I would like to see you report on absolute max range (flat road) for all of the above you are using on for cars only, not Semi trucks. I believe the DSR can do almost 2mi.
I think we've flogged your 34.7 short distance results w/o reaching any conclusive answer I'm afraid.
