For a hobby project I have, I need to make a circuit that will transmit a radio frequency between 10Hz and 25kHz. I don't need to know the specific frequency being emanated so I'm fine with controlling the frequency with a variable potentiometer. I'm aware of the issue of RF interference in this spectrum so I only need something with enough power to send the signal about ten feet. I would expect to run this thing off AA batteries.
It would be an added plus if a speaker jack could be included in the circuit so that, for frequencies in the human hearing range, I would be able to plug in my headphones to hear the same frequency as the RF signal.
I have a very basic working knowledge of electronics.
What do you think? Is there an easy way to do this?
Thanks in advance for any help you can give me.
