Muito interessante

Hi, I have one UHF Converter in my collection at home. It is of Czechoslovakian manufacture, type: Tesla 4952 A. It was on our black and white TV of Czechoslovakian manufacture Orava 132 until 1981, when my father bought a then expensive colour TV. Nice and interesting video.

[@GoranDzambazov]

Interesting. I see that both devices have a similar design.
Thank you for the info.

[@donmurox]

Thanks it was helpful

[@GoranDzambazov]

Glad to hear that!

[@jugoslav91]

I was fixing those a long time ago, thanks Goran for creating time-machine

[@GoranDzambazov]

Thank you Nenad, I'm glad that you enjoyed this time travel to the past! :-)

[@gladstonerodrigues]

Qual é nome da marca desse conversor? E porque não conectou direto na televisão 📺 para vê se pegava canais mesmo?

[@GoranDzambazov]

The converter was manufactured by the Ei Niš factory, located in Niš, Serbia, in the time when Serbia was part of Yugoslavia.
In absence of TV stations that use analog terrestrial transmission, I'm using a setup that consists of a television pattern generator made by Grundig (as a source of the UHF signal), the Ei Niš UHF to VHF converter (connected between the generator and the TV) and a Samsung TV. I hope that this answers your question.

Imam Magnavox kozola sto ima izlez na kanal 3 i 4, i crno bel televizor sto go popravam ama toj podrzava samo vhf. Dali ke rabotat zaedno ovie dve raboti ili ke treba da pravam AV mod?

[@GoranDzambazov]

Каналите 3 и 4 се од опсегот VHF I, што значи дека треба да работи со тој телевизор.

[@windshield11]

@@GoranDzambazov Okej, fala mnogu. Predpostavuvav deka bi trebalo da rabotat edno so drugo deka se po dizajn od sedumdesetite, mada televizorceto e rusko a ova konzolava e germanski Magnavox praven po licenca. Bi trebalo malku da se razlikuvaat kanalite ama ako treba ke go rashteluvam tjunerot nisto strasno. Fala uste ednas.
