Re: TX500: A Five-day Rollercoaster

 

Willis,

No, I did not install any isolation capacitors on the cables.? The GX12 connector assemblies are too small to put any components inside.? Plus, I assume that adequate isolation, blocking and shielding components are built into the radio.? Maybe just a ferrite choke around the wires will be adequate.?

I just found this cable in my closet.? It has 3 shielded individual wires with a ferrite core molded to the cable.? If I can get the 3 wires to fit the GX12 connector, this might be my solution.? I will remove the existing 4-wire connector to keep the wires as short as possible.

The Lab599 has sent me an video of how to disassemble the unit, take the PCB out and indicated the location of TDA7056AT. But replacing SMD components is beyond me, I will need professional help on this.

The Lab599 has also confirmed that there already has been "several cases."

Henry, do you have isolation capacitor installed on your data cable?

Thank you.

Sincerely,

Willis??
