Radio Shows

I was recently given a copy of an old radio show called The Shadow. I enjoyed listening to the program, and could not help but wonder if there are any new radio shows being broadcasted. I found a few shows that air in the UK, but I could not find any in the US. Does anyone know if there is a station that still has radio shows?

Battery removal from Mini Bluetooth Radio?

I have a battery that is dead inside a mini portable Bluetooth Radio, the radio can work only plugged for few minutes, then it turns OFF, a radio assistant says : "please recharge your battery"!!. As it is a Chinese product, i couldn't find this type of battery, i've taken out the battery and plug the radio directly to the adapter, the radio runs for 1.5 seconds then is turns off!! then a loop like this runs endlessly! so am wondering if there is any way to remove the battery element completely and use the Radio only with cable.

Is using PCB in a radio circuit a problem? Answered

I am making this FM bug: https://www.instructables.com/id/FM-Listening-Bug-Kit/ . I decided that I would use this instructable as my first PCB creation. However, I read that the copper creates small capacitors and would ruin the circuit. Would this be a problem on PCB?

Turning AM/FM clock radio into just a radio?

Hey guys, I'm new to this forum and couldn't quite find the answer to my question.  I have a cheapo AM/FM clock radio and thought it would be a fun Sunday afternoon project to turn it into just a radio.  I don't need the clock/alarm function anymore (I use my phone) and my dog likes to have some noise around when I'm not home (TV is an option, but I hate leaving the screen on all day).  Currently, the radio only turns on when the clock is triggered by the set alarm time...and it only plays for a max of 60 minutes.   Should be easy, right?  I opened the clock and couldn't quite figure out what I'm looking at...

DELAY MY RADIO!

I love baseball.  I want to watch the World Series on TV, but I don't want to listen to the TV announcers.  I want to listen to the radio broadcast instead.*  Problem is, the "live" TV arrives 1-2 seconds after the radio.  Which means I hear about the deep flyball to left before I see it. And that takes the fun out of watching the game. So, I'm wondering if I can add an adjustable delay to the sound from my radio, to sync up with the picture.  I can sacrifice a boom box or other radio for this if nec. Or some other solution? (I can record both and sync 'em up later using video editing software, but that's not practical). * for baseball fans:  it's the choice between the Buck/McCarver team (perfectly boring & perfectly obnoxious) and Jon Miller/Joe Morgan radio team (passionate and fun).

How to make a single frequency am radio receiver?

I know how to make a 1 mhz am radio transmitter, so now I want to make a 1 mhz radio receiver to receive audio. I would prefer to not have to wind any coils and just make solid state with few components. Do I need to have a coil to receive the radio waves? Also can someone link me to an explanation or explain how I can demodulate with a 1 mhz crystal oscillator. I don't want a link to 'how to make an am radio' I can do that myself. I just want to know A. how to receive the radio signals hopefully without a coil (only using a variable cap?) and B. How I can demodulate using a crystal oscillator. Can I somehow receive the signal using an oscillator like was done with a 555 timer here https://www.instructables.com/id/555-timer-radio/ Links to schematics / pictures of schematics must appreciated?
