Marconi Instruments TF801D/1 AM RF Signal Generator
Manufactured by UK-based Marconi Instruments, the type TF801D/1 is an RF generator covering frequencies from 10 MHz to 470 MHz. Built at around 1960, the instrument is likely to have been pretty expensive if only for its highly complicated mechanical assembly. I got this generator ‘thrown in’ when I bought a second-spectrum analyser about 15 years ago. Since then, it has provided steady service in my workshop set up for the construction or repair of amateur radio transceivers.
