Hey! I built the AM transmitter. Its works awesome-ly. I have some wires stranded around my basement and the signal can be heard around my house. I felt my oscillator and it felt kinda warm. Adding an old computer fan on top seemed to help, but I dont have that many batteries!

I have 3 questions:

Is it OK to leave it on 24/7?
Should I use 5Volts instead?
Is there any way to improve the signal upstairs?

Thanks!

The oscillator can run hot. It won't hurt it.

If you want a better signal, you can get a license (easy to do) and put out more power,
or you can get a more sensitive receiver, or you can use a bigger antenna on the receiver.

That's good! I was really worried I was feeding too much power into it. I'll look into the license too. I heard if you get the right transmitter/antena, you can broadcast 1/2 mile away without a license.

Thanks again. It was really fun building this, and I learned how to solder!
