FM Transmissor - Pitch Noise Problem
 

Hello everyone,
I bought a FM Transmissor and I´m facing a problem that I believe is happening to another users from this forum.

When I set the frequency that the transmissor will use to transmit the FM radio wave and hit the "ON" button, any radio that play the same frequency near me will listen to my songs....BUT...I can hear a disturbing NOISE, like a pitch noise, pi......pi........pi.........pi.........pi........ ..pi........pi.......pi, that I don´t know why it´s happening.

I have searched many forums and I saw something related to a "noise filter", that this kind of "FM Transmissor Wireless" don´t have. Maybe one of you that saw or read something about it or Know how to fix it can help me and other people with the same issue.

Please, any suggestion will be valid.

Thank you in advance

What FM range is your transmitter transmitting in?

I have one that is transmitting in the 88.x range and it works fine on my car stereo. There is an occassional 'static' noise, but as I keep driving, it goes away, so I think it's depends on the LOCATION.

Have you tried the other ranges available on the transmitter?

Hello Binh, Yes I have tried a lot of ranges....
My transmitter works in any range I set it to work...but I will try once more in the range 88.x.

If I record the pitch noise, would you like to listen to it?

Thank you
Best regards friend

I don't have the same FM transmitter as you do. Mine has a cradle so I can sit my MPx in it and it plugs straight into the lighter plug.

Mine also only has 4 preset ranges.

Quick question, you have tried turned up the VOLUME on your player to FULL then compensate it by turning down the stereo volume alittle? Maybe that might 'lighten' the pitch noise?

Otherwise I would suggest try to get a hold of another one as yours might be faulty.

Actually, try it in ANOTHER car if you can see what happens?
