AM Radio

Schematic: http://i263.photobucket.com/albums/ii151/cameramanlink/AMRadioS.gif
Homemade AM radio. This circuit uses the standard All American Five design with series wired tube filaments. It is based off the Heathkit GR-10 with the addition of direct output and speaker jacks. Sound recorded with the shotgun microphone shown in the video. The direct output was recorded directly to the left camcorder.

The quality is so good!

@CassetteMaster Thanks! This has good quality because it's a superhet, a common design of the 50s and 60s. I don't know why, but radios of the TRF and crystal types don't have as good sound quality. You should try making a superhet on your breadboard. I've seen IF transformers for transistor radios online. They also have TRF radio chips that look like transistors, but are actually ICs.

@CameramanLink Is the ZN414 one? I have one of those.

[CameramanLink]

@CassetteMaster Yes, and I think this is the same one I used in a kit project a long time ago in my quest to build a well-working AM radio. This is going back quite a ways, but I think I got mediocre results with this chip in the kit. There are probably schematics online for circuits with this chip.

Sounds good, looks good too.

@AllAmericanFiveRadio Thank you. I hope the new one works just as well!

Bravo! The performance of the radio sounds excellent in AM band.

@umajunkcollector Yes, I often use new components in my projects, just because they're smaller and easier to get. Point to point is the only way to go; no PCB for me! I wish I had some chassis punches though because it would make things a lot easier (I use hole saws which make a mess).

@laurdy I can do that. That's a good idea! That'll be my next video! I have 3 transmitters and I'll do that with one of them. Check back next week; it should be up.

@ArmaHighVoltage That it is! That's why I make these videos in the first place
