RC Subs are good to about 10 feet in really clean water. I'd like to go deeper than that. Thanks John -----Original Message----- From: Scott F.

I am thinking of using 2m amateur transceivers on either end, and I'm wondering what kind of range I can get with a couple of watts. Also, if I put one half of the antenna (either ground or radiator) in the water, will that make a difference? TIA John -- http://www.piclist.com#nomail Going offline?
