If you want to work on conversation gear — primarily in the 1960s — you possibly required a VTVM (a vacuum tube voltmeter), a way to produce frequencies, and a way to evaluate frequencies and electricity. The Soviet army experienced a piece of moveable equipment that could do all of this, the IK-2, and [msylvain59] displays up how just one looked on the outside and the within in the online video below. Be warned, even though. The online video is hard to halt looking at and it operates for about an hour, so strategy appropriately.
We never browse Russian, but centered on the online video, it seems like the lefthand piece of gear is a frequency generator that runs from 20 to 52 MHz and a electric power meter. The right-hand instrument is a VTVM that has some way to measure frequency and the center segment is a quartz crystal frequency standard.
The machine has a battery, despite the fact that there have been troubles with it in this device. It can also choose exterior energy. Inside the portable scenario is a strong-hunting pair of 100 ohm resistors in parallel to type a 50 ohm dummy load. The circuits within are, as you’d hope, substantial absolutely hand-soldered parts.
In accordance to a single of the reviews, the abnormal tubes inside of were being originally designed for Sputnik. Though it is really hard to consider these days, in the 1960s this instrument was a marvel of miniaturization.
It is fascinating how identical navy gear seems to be from possibly aspect of the iron curtain. Or room components.
