International Trioda Society Meeting
"Local Manufacturers of Radio Receivers from the Second Polish Republic Period - Poznań, Łódź, Katowice"
Grzegorz "gsmok" Makarewicz,
The meeting took place on April 14, 2013, in Warsaw. The venue was Nicolaus Copernicus High School, Bema Street 76. Unlike my participation in the October meeting (report), this time I arrived late (someone, out of spite, scheduled the meeting to coincide with a Formula 1 race report 😬). I was punished for my lateness before entering the meeting room – it turned out I was missing a "tag" for my ID badge – good for me. I was a bit surprised, because if I recall correctly, a few tags had been left unused the previous time. My surprise quickly gave way to amazement when I found myself in the meeting room 😮.
It turned out to be absolutely packed with participants. I honestly didn't think there would be so many people. Just look at this photo for yourself.
Quite a view 😄. And this is just a fragment of the room. But let's get back to the details for a moment. The following meeting agenda was planned and implemented:
- Welcoming guests.
- Trioda Society - nearest plans (Mariusz Matejczyk).
- Battery Receiver Factory "Radjofon" (Henryk Berezowski).
- Radium, Triokong & Silesia (Mariusz Matejczyk).
- Receiver manufacturers" Łódź and surroundings (Maciej Białecki).
- Curiosities from the renovation area.
- A collectors' exchange forum combined with a mini-stock exchange.
After completing the formal requirements, I invite you to view the photo gallery. The photos presented are not arranged chronologically – I've divided them into several categories so that those interested in specific information (e.g., a photo gallery of the collected radios) don't have to sift through the large collection of photos I've included here.
Meeting participants during lectures and breaks
That greenish jacket on the arm of the chair below to the right is my seat. Imagine how much I had to fight for it. Every time I reached a chair, it turned out to be already occupied. Finally, I found one, and even though the "owner" would come calling, I didn't budge and secured what was mine with my coat 😋.
A "Łódź" accent appears on the screen. The speaker is preparing for his presentation. I didn't realize there were so many radio manufacturers in the city of Łódź 🤨.
The two photos below show a presentation on making a "retro" power cable. This is a component of the meeting, included in the agenda as "Interesting Facts from the Renovation Area."
The screen shows (unfortunately somewhat blurry) the mains power cable made by the Author.
And here's the farewell to the participants. It was good, but unfortunately it's over 😒.

Just Telefunken. No additional information, unfortunately. The color is somehow out of date.

And here is a table with interesting advertisements and information materials from the era.
Mini-stock exchanga
Poor thing, destined for a trade. I hope it falls into good hands.
This table is a real treasure.
When I had my camera, it was closed. When it opened, unfortunately, I didn't have my camera with me. When I ran and came back with the camera, it was closed again 😒.
Yum, yum 😉.
I went back and "snapped" the contents of that table again.
I stand quietly in the corner - maybe no one will notice me and I will go home.
Finally, a fun fact: The organizers ensured the right atmosphere. During breaks in the proceedings, the audience could hear the sounds of atmospheric music played by a beautiful Elektrit Victoria radio. It worked hard to enhance the already wonderful atmosphere of the meeting. Here it is:
It's a shame that Trioda Society meetings are held so infrequently. I'm already looking forward to the next one.
