Q: I have a number of different subjects and have the best range I live out of town, so I doubt there are many wireless networks nearby.

The difference in frequency between 802.11b/g channels 1 and 11 is so small that I doubt you'd see any change in max range (even in a lab environment).
The limiting factor is going to be the noise level in the environment at those frequency bands (as was stated by Jack)
We simulate distances by using variable attenuators, and I have never seen a trend in beacons to support any channel as having more range. Of course, this is in a lab, and we aren't measuring distance, but rather signal strength. I would fire up netstumbler and wander around with your AP on different channels, to find the best SNR, as has been stated.
One thing about 802.11G is that the channels share frequency to a point. Channels that are 4 channels off (1 (2 3 4 5) 6 (7 8 9 10) 11) do not over lap. In general, you want to get as far away from other APs as possible, shooting to be 4 channels from everything.

Re:Channel 11 is most likely to be interfered with by (some) microwave ovens.
Otherwise all the same (except freq).

what is a channel exactly?it would seem that they can't be right at 2.4 GHz unless the bandwaidth is not being all used and if not why did they not use it?is it incremental frequencies like 2.41GHz and 2.42GHz?
yes. remember when you had to tune your TV to "channels". Same thing.

Re:Channel differs only in the frequency that they are working at.
You should choose the one that gives you the best Signal to Noise Ratio.
As an Example if you have two neighbors one uses ch.6 and one using ch1, you probably would do the best with ch11.
