What's the difference between the standard horizon hx890bk and standard horizon hx890nb two way radio?

I believe the HX890BK is the black one and the HX890NB is the same thing in a navy blue color.

A range of five miles sounds low. Is it anyone’s experience that this is adequate? Is there an extension to the antenna to increase the range?

Five miles is about as good as it gets for a handheld marine handheld. Note that many manufacturers (not Standard Horizon) puff up there range by claiming a range of dozens of miles from a handheld. VHF is line of sight communications. If you are hanging from the crow's nest, you might get greater range but if you are standing on the deck, don't count on it. HAM radio operators talk with International Space Station astronauts with 2-watt handhelds at a range of 250+ miles because there are no intervening objects. The same handheld would be lucky to reach a mile on the ground to reach another ground based radio. Similarly, a 6 watt VHF handheld might reach the moon if there was anyone listening but at sea level your range will be limited to what you can see or less (horizon). For greater range, use a radio with a pole mounted antenna.

Does this radio have an emergency DSC call distress button like the units that are mounted in the boat?

Yes, but you require an MMSI number to input for it to operate.

What is the color of the night time backlight?

Letters and numbers are black, back light is white, both are adjustable.
