Radio Theory Part 1

[@andyfritchen6409]

I have watched many vintage radio videos for various repairs but this video is right up there with the best basic explanation of radio operation I've come across. Nicely done and thank you for your time and effort.

Very good Dennis! I picked up a few little things that I didn't know - well worth watching! Great, steady, organized approach! There is no way I could come close to your teaching skills, I would be jumping all over the place! You connect it all together quite well!

Thank you for that, that is the best explanation of the oscillator circuit I have seen so far.

Thank you,best introduction to how a valve radio works.

[@LouinVB]

Thank you for the excellent explanation. I have a Zenith radio that I can pass an AM signal straight through from the mixer to the speaker, but it does not tune to any station on its own. You gave me some ideas as to what to check. BTW, I do hear interference on another nearby AM radio as I turn the tuning knob on the defective radio so most likely the local oscillator is working on the defective radio. The radio has been fully recapped, and the FM band works great. First thing I'm going to check are switch contacts.

Great explanation! I learned something even though I've repaired a bunch of these and kind of know how they work.

Thanks for taking the time and for sharing your knowledge in such a clear and lucid way. Beautiful video

[@ernestberry-songsrestored5637]

Thank you so much for all your videos. Absolute gold dust !

Dennis-Just found you channel a few days ago. Your videos are fantastic!!!You are an incredible teacher! Thank you so much for all your effort in making these videos. I'll be watching them every day. Get better soon. We need you! Take care and may God bless and heal you. Chis

Thanks for the video. I got a better understanding of the input stage.

[@fibberscloset498]

Just found this video and your channel. Nice explanation!

[@victorwilson6826]

It's nostalgic how you still call a capacitor a condenser. Great video though.

[@teeeeeeeeeet]

Excellent. Looking forward to part two.

[@Ragitysdad]

Thanks Dennis it is starting to sink in.

[@francismannion7075]

Wow ! That was a great explanation thank you very much.

[@BretFrohwein]

These are great! Thanks Dennis!

I have a 4 band radio but not thats circuit diagram it has MW SW 1 SW2 SW3 SW3 its oscillator coil is 5 pin and 2 pin gives continuty one hand on the other hand 3 pins give continuty (Center tapped ) aprt from center tapped rest two of these 3 are grounded I couldn't guess how tank circuit is being constructing over here
