Kind of you to say that, Mike. I'm not surprised you've done well for yourself, you always did. Sometimes I am still amazed when I think back to the dedication and commitment so many had, while making barely livable salaries. Our country got quite the bargain. :). Be blessed, my friend.
Before the conversion to OT, ETN/ETR ratings did the maintenance and repairs on the radios, transmitters, antennas, and fix sonar system (including tape recorders).
My expertise in computers and electronics just got better and better. It became my hobby as well. But what I did as an OTM was the best most diverse tech I was allowed to work on. When I get challenged there are so many examples to draw on.
