Autocom noise problems
Hi to all, spring's almost here.
I'm having some irritating problems with my seven pin autocom system that I hoped someone else may have some input on. I am using a Garmin Rhino 120 as the radio entity on my system only because the guy I ride with most of the time uses the same. Here are the problems I am experiencing: 1)After I speak and the mike closes, there is a single loud "chirp" noise which can be heard by me and the person receiving. This does not happen when the other person speaks. 2) When I receive a cell phone call, after about 8 seconds into the call a very loud ringing noise occurs, which makes continueing with the call almost impossible. Neither of these problems seem to change regardless of which position the ptt switch is in or if the ptt button is being used. 3)When I power the unit off the map light circuit, there is a lot of RFI which can be heard by others when I am transmitting. The RFI is engine speed related, ie as I accelerate, the noise gets louder. Not a clicking, but a whining.
I haven't tried using another radio, but sometimes it works fine with no problems at all.
Any help would be appreciated as I am just about to ride to Texas Hill country and Big Bend and this will be very annoying.
Thanks in advance
