Hello engineers, I've been wondering if you would help me with my problem I'm currently facing. I'm student and I want to learn as much electronics as possible. That's why I'm asking for an advice. I'm creating my own AM Transmitter project for my school things. I just wanna know these things:
Thank you for your response.
- Where can I get the source of carrier frequency (instead of buying some lab generator). Some integrated chips, or?
- Can my audio signal, alongside with carrier frequency (together) enter the transformer to step it up to some higher voltage level than I would obtain from LM386 audio amplifier? I think this would boost the transmission even more, am I mistaken?
- Can I use a straight wire antenna of around 2 meters? I don't wanna buy any of those perfectly-made antennas they sell online.
- What carrier frequency would you suggest to me? Somewhere around 20MHz?
Thank you for your response.
