UV-82HP Programming

Hello,

I recently purchased the UV-82HP to use while boating. With all of my prior VHF radios I've been able to tune to the channel and send/receive without issue. It appears that with this model channels have to be added/programmed in manually.

I've read through the instruction booklet, watched the youtube video and reviewed these websites but have not been successful in getting the radio to work.

I'm located in Marblehead, MA 01945, Essex County.

I understand that I need to be in frequency mode in order to program a channel. I do not have the capability to connect the radio to a computer. At a minimum, I would like to get channel 16 working for the Coast Guard. I'm hoping someone can provide some help. What frequency do I use? Do I need to add the Offset? Any help will be greatly appreciated.

Thanks
