Finally had a chance to spend some time in the shop this afternoon after a too brief stretch of spring weather, which I spent outside cleaning the yard of winter debris, and playing with the dogs.
As I said earlier, my oscilloscope was not working, so I took it apart (breaking the Tectronics seal) which voids the calibration. I didn’t find anything electrical wrong, but cleaned all the contacts, switches, and rheostats with “Deoxit”. Anyone reading this who is not familiar with Deoxit should become aquainted and purchase a can (aerosol).
Re-assembled everything after a good dusting and air spray, and, IT WORKS.
My friend Pete, KB7OVJ, in Oregon sent me some extra fiberglass alignment tools which arrived in the mail today. So now, I have no excuse for dragging my feet on the alignment process.
(so now back to work)
