I had a JRC VHF radio below decks as a back up and convenience item. Anyhow, the mike cord on it began to unravel badly and delaminate. The radio is no longer serviced in the US and the cost to open it up was more than the cost of replacing it. Anyhow, since it still worked, I was going to put it on ebay until I realized my MMSI number is in it. I would not want to sell it with it, and I recall that there are only two tries to enter one in before it locks up, so I can't put all zeros in for example. So, I guess I'll just toss it, but figured I'd test my thought here first. Agree?
