    ten watts out the radio draws 3 amps

    i like gel cells they are cheap
    and easy to use

    using my IC 703 portable
    power it with two 7 amp hour gel cells

    at ten watts its good for one day at 20% transmit
    at five watts or less its good for the week end

    Hi
    When I had a 703 I set it to use the timer off function set to 60 mins in case I didn't touch it for an hour it would shut down, display backlight timer enabled or no backlight, in daylight you can see the display pretty easy without the backlight, no switch/button backlight, and ran it off a 18ah gel cell. Ran for days at 10w, mostly rxing though. Add a small solar panel and you should be good to go.
