Oh, so you didn't have a license then. Smack handy you bad, bad boy
I did actually.
Another project I had on the go back then was a pirate radio transmitter, about 500 watts (a couple of 807s) and this needed about 700V DC. The obvious place to get that was the power rail on a train track. And no I didn't get a license for that one
We never got it going, because we found that the power wasn't there all the time...
