Red face 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

I'm an "audio guy" . . . and, a "phone and computer guy". No matter what job I'm doing, the first thing I always suspect is the cable. Sounds to me like the cable going from your Rino TO the AutoCom is bad. Either it's not shielded properly . . . or it does not have a GLI (ground loop isolator) built into it.

I have a Rhino 120 and the bike power is a major problem while sending (only) and nothing to date has fixed it. To spare my co-riders the noise, I just operate on battery power. I have a SPIII so I don't use the GPS function on the Rhino. I don't know about the chirp but you might try swapping radios with your friend to see if it is in the radio setup. It can get strange with all the possible radio setups available. I did have a bad cable to the Rhino that had a short which allowed me to hear but I could not transmit. The cable was exchanged at no cost other than shipping.

If you find an isolator or choke combination that will clear the power cable to the Rhino, I would love to hear about it myself as that is the only thing negative I have found about the unit.

Update

I think I solved one of the three problems. The chirp that occurred after I spoke was probably that the radio setting "roger tone" was enabled. The ringing that occurs when speaking on a cell phone through the system comes and goes without any consistency. This did not happen to me but did happen to the guy that I was riding with. I think the Rhino is pretty quirky and with so many settings it may be the root problem for these intermittent problems which are exaggerated by operator error.
Hope your weekend is great!

get a new riding partner

Don't blame your goddamn problems on your riding partner. If it wasn't for him you'd still be stuck at some goddamn intersection trying to figure out whether to turn left or turn right! You wonks spend more goddamn time trying to figure out self-created problems than any other biker group. Strip all that goddamn crap off your bike and try to remember why you bought the goddamn thing in the first place...to kiss civilization goodbye!

Autocom makes a special noise reduction (audio) cord. I have not had any problems since.

Yes, but in comfort and with convenience. LT stands for Luxury Tourer, you know. If that doesn't float your boat, you could always buy a Hog and strip off all the unnecessary bits.

Or just ride one of these:

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Oh lovely, our old friend, the banned Archw is back. But not for long.

What do I smell? Might that be a little ozone?



Gone.
