I think back then the 2N2218 transistor and the Toyocom crystal filter were under embargo and export into the zone behind the iron curtain was not allowerd. Interesting that they got hold of them anyway.
Ça me donne presque envie d'essayer de construire une radio RF pour comprendre comment les ondes fonctionnent... Vraiment un beau morceau esthétiquement, ça l'air presque simple en plus... C'est juste très joli à l'intérieur par contre comparativement aux petits blocs noirs sur fond vert qui sont si communs aujourd'hui... Probablement le circuit le plus coloré que j'ai jamais vu! Très attrayant! 🙂
I have a question. The current Varta CP300H 9.6v NiMh battery (2 needed for this radio) are too long, the battery cap won't fit. Did you find a good replacement battery? Second question, the cap has a "+" emblem on it, so do I assume you insert the batteries with the positive terminal towards the back of radio, and the cap comes down on top of positive?Thank you!
Hi, can you not just give the modules a good soak in a bath of isopropyl or something like a solution of biological detergent? It seems an awful shame to throw them out.
Beautiful circuitry.

That's what i wonder - was this radio for military? They could use only COMECOM parts for military hardware (officially).
Bulgaria was a broker for such things, trade of rare goods betven west and east.
Iron curtian had a few holes left for purpose

Hello Mr. msylvain , Thanks for the video. They are amazing, like you, I look forward to your next videos
Interesting. Like.👍
👍👍👍👍👍😃
Hi, c'était juste des récepteurs ou il pouvait émettre ? c'est peut être pour cela qu'il y a ce relais .
C'est bien un émetteur - récepteur, 0,4 watts de puissance de transmission.
@@msylvain59 Ok, merci !

Your scrap radio fell into water or worse, a privy.
Nasty, burn that one.
Thanks for the video.
