Good day all,
I was wondering if I could ask you all for some advice/assistance on how to make a modification to a RF transmitter circuit I am working on.
The link to the schematic of the transmitter I am working on can be found here: http://www.bugplan.com/bbg.htm
I am building this transmitter (for a purpose other than a bug), and figured out that I do not need a microphone (as pictured on the schematic), but an 1/8th inch audio cable input instead.
However, I am not sure how to go by swapping the microphone with that kind of audio input, or if it is even possible. If you guys have any info on how to do this, or, better yet, know how, please let me know. That would be a great help!
Oh, and in terms of legality, I own a business and would be using this circuit to transmit on a frequency I am licensed to do so by installing a different crystal into the transmitter.
Thank you for your time and expertise!
