From the Kenwood USA web site:
"Kenwood's compact mid-tier display portable line offers enhanced features for the budget conscious volunteer public safety, public service, government, industrial and SMR system user segments."
Now here is THE question, what are you doing or plan on doing with it? Unless you're an authorized user of one or more of the above and fall under the agency's/corporation's blanket license transmitting is strictly verboten. On the other hand they issue radios from the pool for use while on duty to be returned when going off so why do you even own it? Oh it's legal to own, the question is WHY.
Here's another thing, marine radio is NOT CB although unlicensed operation is permitted BUT only on the water, all other operation without special licensing again is verboten. Still it is not CB even if so many yakking it up on pleasure craft channels think it is so the end result is it sounds like CB with all the hoopla and stepping all over each other so a portable will only get lost in the sauce. Being in Long Branch just listen to them on your scanner come Benny season and you'll hear the mess for yourself.
Not to be insulting or anything but all things considered I don't think you're ready for a radio that talks. You may consider reading the CB and Amateur Radio threads here and check out some of the AR web sites and forums becoming a bit familiar first (you don't have to register, just read) and then come back with some far better questions we'll be happy to give far better answers to. Oh, kindly avoid the CB internet sites and forums unless you're prepared for your sensibilities to take a beating. Unfortunately most have become the low places on the internet (like a couple of ham forums I no longer visit) where loonies and "morans" gravitate to thus giving an otherwise good form of communication a terrible black eye.
Just point yourself in the right direction, THEN we can talk.
