Sorry the picture doesn't do well to show the connector. I tried manual focus, but it is really, really small. The connector is crimp on and inserts into a socket on the final PCB inside the back of the transceiver.
Sorry I wasn't clear enough in my fist post.
This IS NOT A LEAD WIRE, but is internal inside the radio
This is for a HAM HF (Kenwood TS-130SE) transceiver, putting out 200 Watts
There isn't really such thing as "MARINE" Ham radios, however this particular radio has served me about 3500 miles aboard my boat, reporting to Pacific Seafarers net. Non-tinned copper is quite common on all electronics marine or not. Even the best RG8X wire will corrode quite readily if the terminations are not made completely watertight.. been there tested that, shrink wrap everything. I use RG-8U for my coax fed antenna, and have had good DX up to 5000 miles.
I did find out that the wire is RG-274 micro coax, and was able to obtain replacement wire. The local electronics store said they have no idea where to get that connector. That is the only store within 275 miles (by water/air).
Unfortunately.. I am beginning to think that this simple repair is going to involve long hold times at Kenwood trying to get parts for a radio made before most of their tech support staff was out of diapers..
