Checking the legitimacy of the claims. Is this radio really 8 Watts? Is it IP67 Rated, for real? I conduct a 15 minute (I know I say 30 in the video) underwater test to see if the UV-9R is waterproof.

Part 1. Leave a comment below what you would like to see in part 2!
Just wanted to point out with the Emissions: The mean power of any spurious emission from a station transmitter or external RF power amplifier transmitting on a frequency between 30-225 MHz must be at least 60 dB below the mean power of the fundamental. For a transmitter having a mean power of 25 W or less, the mean power of any spurious emission supplied to the antenna transmission line must not exceed 25 µW and must be at least 40 dB below the mean power of the fundamental emission, but need not be reduced below the power of 10 µW. A transmitter built before April 15, 1977, or first marketed before January 1, 1978, is exempt from this requirement.
With that, while operating 5W on UHF, this is right at 40 dB below the mean power of the fundamental emission. power emitting from the spurious emission is somewhere around 23µW.
I'll test this further in part two, along with the explanation of the 2 cell battery.
Thanks again for checking everything out.
