Have you recorded the things before they've constructed? Or it was just tinkering? No - no, it has - I've already made a plan. And since I'm so - all the circuits I've recorded them all. Des was actually very complicated, tube circuits were, until then came at the end. So as an amplifier - in order to gain the high number of functions, it has - in his inside - the amplifier in another - the so-called intermediate frequency amplifier. He has always had the same frequency. So 100 pounds - 100,000 cycles per second. And because the sound waves have come in two tubes, that was a normal amplifier. Then it is on this intermediate frequency amplifier - that was another frequency that you had to vote on the stations. And when it came to the intermediate frequency, which was amplified without voting. And since you had at the end - there had been a discriminator. You had everything set up the same and continue to implement and language, because otherwise one would have heard a word. Because those were been different frequencies. So this had on the so-called voice frequency .. that number to 300-5000 cycles per second. This is the actual speech rate. This had to implement it and had to do this, build the amplifier.
