Hi all,
I spent a number of years working as a
communications tech. One day I got a call from one of the logging companies we dealt with. One of their tugboats had sunk at the point where the tide changed. It had been below the surface when the tide was high and was now partially out of the
water at low tide. They had the
marine VHF and 2-meter
radio removed and sitting on the
dock. I told him to put both in a bucket of fresh
water and bring them to me.
When the foreman walked in with the bucket of water there were a couple of customers in the store who looked inside and laughed. Telling me I was crazy and to throw the radios in the bin. I made a bet with one of them for 20 bucks that I could get one, if not both radios back up and running perfectly.
The 2-meter was a Motorola worth 1200 bucks, so it was certainly worth a try for the logging company.
I took both radios apart, removing every piece I could and laying them out on a workbench. Then I took a can of PLID and completely covered each part.
Then I left them alone for three days. In the afternoon of the third day I wiped all the excess off, making sure any pins and connections were clean as its a dielectric. Then proceeded to reassemble both radios.
Both radios powered up and worked perfectly when connected to my
monitor. The Motorola had 49 watts on transmit. Not bad for a
radio rated at 50 watts that had been in
salt water for 12 hours. The
VHF was around 20 watts on transmit, it was rated at 25 watts, but they are always a little high on quoted ratings in my experience.
Both were taken and reinstalled on the tugboat and used for years afterwards.
I collected my 20 bucks and the logging company were very happy customers.
One thing to remember when using this is that it is a dielectric and any connections you put it on will stop being connections. We had a guy who put it on a bunch of
electrical connections on his backhoe. It stopped working until he cleaned it off.
I have no connection to the company that makes it, just wanted to share this because it really does
work and might save someone a bunch of
money or even their lives. Here is the link to their site.
