Thumb through an old Dutch radio book of the 1920s: the radio book for trade, amateur and listeners

Thumb through an old Dutch radio book of the 1920’s, named “Het rt adioboek voor den handel, amateur en luisteraar”, door ing. (engineer) J. Schiere, issued by Karel C. Schoemeijer, Bussum, the Netherlands, in the 1920’s.

Translation of the title: “The radio book for trade, amateur and listener”.
The video tells everything and needs no explanation further.
When you need more info: go the the website mentioned in the first minutes of this video (worldradiohistory). Thanks to Barry Blod, one of my YT followers, to give me this very important link for everyone interested in electronics/radio. You can find much inspiration there! 17 okt 2021.

Correction: on 14.38 I say: “transistor coupling” but of course I mean “resistor coupling” between the (in this case) 2 triode tubes, also actual nowadays (2021) when you want to couple transistor stage A to transistor stage B.

Could be done with resistor coupling or with a transformer coupling. More in my books. They all have their pro’s and con’s.

Sometimes the right English/American words for all these specific radio circuits don't pop up directly, sorry for that, I hope the explanation is enough combined with the elecronic schematics that everyone can learn/watch. E.g. the Dutch word "handel" is not "handle" but "trade".

When you have questions about (certain analog) electronic circuits and how to make them: go to my Channel trailer (Radiofun232 on You Tube) and go to the “looking glass”.

Type there the keywords that you want/need like: “power supply”, audio amplifier, capacitor tester, oscillator, radio, shortwave, shortwave radio, or any keyword you like to find the essential info & schematics on my YT channel.

You can contact me via email when you have questions about my published circuits. I always ask for a picture of what you have made + a problem description; I ask to communicate. When you don’t want to give information/communicate: please don’t ask help. Sorry that I am so strict now (since 15 may 2021).

It has to do with disappointing reactions of people since then that asked “help” (even fake help) and did not react afterwards or asked questions when they knew the answer.

My You Tube channel trailer is here: https://youtu.be/xbgQ8T3oqh4 When you search, search always “NEWEST FIRST” to get the right overview. You can also search via the “looking glass” on my Channel trailer via keywords like ”audio”, “radio”, “amplifier”, “filter”, “Shortwave”, “transistor”, “FET”, “oscillator”, “generator”, “switch”, “schmitt trigger” etc; so the electronic subject you are interested in. My books about electronics & analog radio technology are available via the website of "LULU”, search for author “Ko Tilman” there.

I keep all my YT videos constant actual, so the original video’s with the most recent information are always on YouTube. Search there, and avoid my circuits that are republished, re-arranged, re-edited on other websites, giving not probable re-wiring, etc. Some persons try to find gold via my circuits. I take distance from all these fake claims. I cannot help that these things happen. Upload 17 October 2021.
