Amplitude Modulate 3mhz carrier

Projects General Guidance
1

Hello All,

I am participating in the Jackson Tesla Magnifying Transmitter replication project (Yahoo | Mail, Weather, Search, Politics, News, Finance, Sports & Videos) and I would like to know if the Arduino Uno is capable of transmitting a 3mhz analog amplitude modulated signal? Ive just started looking at the Arduino and it appears very versitile. If it is capable of this, are there any additional addons I need to purchase with the Arduino Uno to do this? Currently the resonant frequency of my device is 3mhz but it may change. I have a junky old function generator that works for short periods of time but it's output diminshes so I would like to use the Arduino as a replacement for it. My plans include transmitting an AM signal to a receiver and eventually transmitting digital data (I will need more bandwidth and therefore a higher resonant frequency. But I'm crawling at this point.

Thanks for any response.
Jim

I wouldn't count on trying to generate such a high frequency directly from an Arduino output.

I would like to know if the Arduino Uno is capable of transmitting a 3mhz analog amplitude modulated signal?

3 micro hertz is high?

That would be "milli Hertz" :wink:

Hahaha that's funny milli and micro. And helpful too. My BAD. Mega hertz for those who couldn't assume that I was too lazy to type the capital M. I guess I set myself up for the wanna be comedians. Lesson- never sit in the front row at a comedy show. Hahaha

Thank you to KE7GKP for your reply. The answer to your question is analog. I can build an analog or digital modulating circuit without using the Arduino. That's not a problem. I was trying to avoid that and have the luxury of fine tuning my transmission carrier (~3Mhz) digitally from the pc. The Tesla apparatus appears to work better sending a digital carrier vs. analog. If the Arduino is capable of that task on it's own I won't have to bother building my own oscillator and modulating circuit. Plus the bonus- I can use the Arduino for other projects as well. I will look at the DS1077 closer. Any other suggestions from the less "case sensitive" experts will be appreciated. -Jim

I rarely assume anything where units are concerned - remember, 1 RPM is 16mHz.

Thank you again KE7GKP for your reply. You have been very helpful. I see why you have God status. I will look at your suggestions... Netduino=700 pages of light reading. OUCH! Maybe I'll stick with building my own circuits for this project for the time being.

Thank you again AWOL for your very informative reply. I will look into the 1 rpm = 16Mhz information. Whoops! Was that M or m? ]:slight_smile:
