Ok, having fixed the other problem with the Lorenz, I ran a 60'
pair from the Lorenz back to the bench in the back of the shop
where the PC and the level converter are hiding.

I put the Tek Scope across the MOS-Fet keyer and took a (bad)
picture of the scope display.

50 v/div vertical and 10 mS/div horizontal.

Looks like 110 volt over shoot with a duration of 10 mS.

Time to fiddle with the values a bit, but overall, I'm pleased
with the results. Although not necessarily impressed with the
quality of the pictures taken with the cell phone.
