Video

Hello! I didn't design it, it's a WWII spy radio replica, it's called "paraset" on the internet, search for everything available. But as I wrote here, it's only half finished, I'll slowly be completely ready with it, then I'll make a new video. So far, there is no QSO with him, but I tested it on websdr on 40 meters at night, yesterday I heard myself on Novosibirsk websdr, which is 4300km as the crow flies and with an output power of around five watts is not bad. My antenna is just a 20m "long wire"

@@Sanyesz855 Я знаю эту радиостанцию, даже хотел повторить, руки пока не дошли. Одно время очень интересовался такими шпионскими радиостанциями времен войны. Да, ее многие повторяли, но ведь каждый немного по своему. 4300 км - это здорово! Класс! Успехов! Буду ждать следующего видео по ней. 73! de R1CBD.

@@Dromidont Thank you, I only modified it so that it works from 6900 kHz to about 7300. The original "paraset" goes from 3.5 mHz to about 8, in one band, with a piece of 100pf rotary capacitor, it is very, very difficult to use the original version. I want to make it a band switch, it can be switched between 40/80 meters, maybe even 60 meters if it's included.

@@Sanyesz855 Да, 80 и 40 метров растянутые будет самое то. Еще раз успехов!

Hi, I modified this to the extent that it only goes 40 meters. From about 6900 kHz to 7300, it works much better. Maybe I'll make it switchable so that it has 80 meters as well. The original paraset with the 100 pf capacitor receives a very wide frequency and is difficult to handle.

Hi, the output power at 50 ohms is 4-5 watts, so far I've only tested it on websdr, I heard about 2-3000 km.

Поддерживаю. Схему в студию!

Nem csak az én érdemem, sőt.....

Since I use a compiler, I don't fully understand the issue, it's a 200 kV transformer, the video is used at maybe 40-50kV, at this voltage its coils don't even pass through dry air.

@@Sanyesz855 but what's the DC resistance of the secondary? I too am curious :)

Szia, igen mind saját.

Üdv! Ismeretség, de ez csak egy vezérlő, a röntgen csöve nincs meg, csak a nagyfesz tápja.

Hi, x-ray transformer

We still have to wait for oil, I have to vacuum it out, I admit I'm a little scared of the full voltage :)

Wow got to be the first douchebag in the comments
