Hi
With TS-480 its mandatory not to use the same power supplys for the Radio RRC and the Radio to avoid ground loops picking up RF
Qouting the website
"The Radio-RRC should also be powered by and external power supply (not the same as radio) to prevent ground loops which pics up HF. If you got that problem it is recognized by distorted audio from the microphone, which gets better and better as you reduce output power"
If it doesnt work you have missed a GND wire somewhere and need the powers supply to connect the GND together which is not good it will be very sensible to RF. Thats the problem you are describe further down in the mail
