I am looking for a good tx/rx voice activated radio design.
Needs to operate on batteries (portable). Needs a 2 km range or so.
I want to install on snowmobile helmits.
I can purchase the retail units at a nice high price but that takes all the fun of building your own. Can anyone direct me to plans or a kit?
