How Superheterodyne Works

How Superheterodyne Works

[@DERB_Seymour_Indiana]

Hey Rick. I've used that method to prove and show that the local oscillator wasn't working on several occasions on both AM and FM radios. Also the color mix was a very good way to show how the frequencies mix. Very good demo indeed. :)

Thanks Doug. It is amazing what you can do with PhotoShop.

Another great educational video Thank you. As a kid of 5 in 1960 the mixing of those pixies has always fascinated me . I found a Rocket Radio in the garbage and have been interested ever since.

Thank you, and your welcome.

Thank you. I am a novice at vintage radio repair and member of CVRS here in Canada. I appreciate the tutorial greatly. Bravo.

The animation of the signals at the first tube really helps. Been struggling to understand these tube radios.

Thanks! I also have a FREE Ebook that may help.

Rick you always do a great job explaining how things work. I hope you have a great Thanksgiving! Jason RadioRescue.

[@AllAmericanFiveRadio]

Thank you Jason, and Have a great Thanksgiving!

Excellent video. Provides a clear understanding of hoe superheterodyne works. Thank you!

Thank you, and your welcome.

Rick, I owned a Motorola Two-Way Comms dealership from 1977 through 2017, hold a 2nd Class ROL (the 'really pretty wall-hanger' certificate, not that "orange copy paper thingy"), and now understand far more about superhet in both theory, and soon, hopefully, in practice. I have three 50's Zeniths, a Crosley, and two "braille radios" in the lineup at my bench, and I'll be performing a much more 'observant' alignment procedure on them thanks to this video. I'll probably cut my ROL into tiny pieces, and mix them in with my corn flakes tomorrow morning!

[@AllAmericanFiveRadio]

Thank you. I’m glad the video helped. Don’t cut up yourROL. Hope you have good luck with your radio projects. It is great getting those old radios working again. I have a FREE Ebook that also may help.

[@CrispyCircuits]

Thanks. So the + side and the - side are both there, exactly the same and adding up to zero. So nothing to amplify. The diode strips of one side and then there is a signal to amplify. This is a good Thanksgiving for me. I've managed to find a great video here and a great short series on explaining and modifying an audio amplifier on another channel. It's actually hard to find explanations that fill in all the blanks, this one did it for me. Have a nice weekend.

Thank you, and your welcome.

Am band is ~ 540 KHz to 1600KHz. Thanks to your video I now understand why 455KHz comes up so often in these things because it is below the AM band.

[@AllAmericanFiveRadio]

Thank you, and your welcome.

[@W1RMD]

Great to have you do a new video! Happy Thanksgiving!

[@AllAmericanFiveRadio]

Thank you.

Hello from New Zealand. I found this a very good demo. However, no mention of AGC. What I have been trying to find out, is why, on many AA5 's is the frame of the tuning gang connected to the AGC and not to chassis? If anyone can help, thanks.
