Yeah my transmitter pretty much sucks. The range, on a good day, is maybe ten feet but usually much shorter then that. I too, often have to raise the transmitter above the window line, and I usually have pretty good luck at that point.

One thing that I’ve noticed is the Volvo transmitters are VERY susceptible to outside interference, i.e. other car remotes, radio/TV/cell towers, plus a whole slue of other “stronger” transmissions. I was battling with some guy in a BMW the other day to try and get our cars locked. On occasion (maybe three times) I have had to use the key when the interference is too strong.

I seem to remember other people on the board have lengthen the receiver’s antenna with some success but has anyone attempted to add a signal booster/amplified antenna to the receiver.

I would imagine that chin technique employed by many allows the transmitter to use your body as an antenna.
