Tbe one that impresses me most is the old analog telephone which
does
everything over two wires without active electronics, only one very
clever transformer, speaker and carbon mike. I couldn't quickly find
a
circuit description and should return to fixing my fallen TV antenna
that had me abseiling down the snow-covered roof.

It's a good thing you were strung up.

I hadn't practiced a Dulfersitz in decades.

Wednesday the forecast was for 10-20MPH winds, not the howling gale
that blew the TV antenna down. Thursday I replaced the bent mast
section, then Friday the predicted few inches of light snow clung to
the guy lines and pulled it down again, and this time it smacked the
roof HARD right over me.

There are 5 oak insulator blanks sitting on the milling machine to be
completed tomorrow. I made one to replace the first fall's damage,
boiled it in wax to drive out the water and seal it, and didn't lose
any signal strength from it.
