I'm new to this forum but been interested in electronics since I can remember. I'm definitely a newbie but have tried minor projects & can solder etc
In my hobby/sport, we use handheld radios to which we have a licence to use them. One radio has a speaker mic with female aux port (I use electronic ear defenders connected via aux lead to my speaker mic) & my other radios speaker mic doesn't.
My question for you guru's is this......
Can I wire a female aux port in place of the speaker or can I wire it in parallel of the speaker
Not quite sure what you are trying to do in the last paragraph. You may well need to examine the aux socket carefully - some have switching to do associated things, such as short or open the audio somewhere. Experiment!
