I'm not set up to transmit on 10M-FM but I do listen to it on my HT and Scanner. If conditions are right, there are no terrestrial limits on range. I've heard Australia, England and Japan come in like they were locals.

If the prop is good and your antenna is tuned, you should have no problem. A lot of people listen to CB to find out what band conditions are. If it's happening on 11M, it's pretty much happening on 10 too.

The FT-8900 is a cool radio. I have the FT-857, FT-817, Alinco and Azden all which have 10M-FM. I also have a 10M h/t but the antenna on it is a joke.
