SDS100/SDS200: Uniden SDS200 and Bluetooth transmitter interference

[Schmelop]

I bought (with a little fear of interference) a Bluetooth transmitter/receiver for headphone out jack on my Uniden SDS200 to transmit to a Pioneer Receiver.
Well my fear was right it transmits to the pioneer but there is a buzzing sound along with the audio when played out of the Pioneer Receiver. Does anyone know of a clean method to do this or another device that will work other than hard wiring all the way.

You probably need a ground loop isolator.

Do other audio sources (when fed into the bluetooth tx/rx) have the same characteristic buzzing? This is diagnosis by subsitution.

I will give that a try and let you know!! Thank You.

No if I stream from my iphone to the Pioneer it is perfectly clean sound

You would have to have your iPhone getting ac power from the same electrical system as the Pioneer receiver to answer this question fairly. The feedback is through the common ground both devices share.

I'm not sure that tis has anything to do with it...(??)

SDS100/SDS200: - Question about SDS200 external speaker jack configuration

Either get a different BT transmitter or a ground loop isolator or both.

Definitely need a ground loop isolator
$10 at Amazon
It's what I use with my SDS200 with my Bluetooth adapter (bluetooth adapter powered by the USB A port on the front of the sds200

Doesn't all SDS200 have buzzing in their audio if they don't have that special no-hum modification being done to them? Listen with your ear close to the internal speaker and check that it has no buzz in its audio. Feeding the speaker audio to a HiFi system could reveal that faint buzzing so much more.

No, I cannot hear that on mine.

Does the Uniden SDS200 USBA port support at least 1amp as my Bluetooth Send/Receive requires 1 amp. It does come with a power supply but it would be nice to use the USBA port.

It doesn't actually use 1A, it's just how its power adapter are marked and are the smallest one you can get. It takes something like 150mA-200mA that are well within what any USB port must be able to deliver.

Ground loop isolator worked excellent. Works best when the Bluetooth transmiter gets its power from the USB-A port of the Uniden SDS200.
Thanks for the help

Thanks for the tip on using the USB-A port to supply power to the Bluetooth Transmitter while using the ground isolator as this worked better than using the power supply that came with the Bluetooth transmitter.
