IU3UHF (Francesco Lorenzi) lab notes
Academic blog: lorenzifrancesco.github.io ยท Thanks to QSL.net!
Welcome to my page where I show some experiments in my electronics lab, involving vintage electronics, RF (and a tiny bit of microwaves), and a bit of acoustics and optics.
-
Troubleshooting poor focus on a 1970s GO 10: checking the HV and supply sections, inspecting the discrete vertical amp and timebase, and replacing a failed plate driver BJT.
-
A piece of vintage radio technology representing early consumer wireless comms (VHF).
-
A dual-input satellite LNB with an "exotic" DRO (dielectric resonator oscillator).
-
Microscope views of some devices: a semiconductor die with logic gate transistors, an LCD screen, and a mysterious piece of thermionic equipment. Can you guess what it is?
