Quantar CWID with External tone/noise

Hi there

Two of our Quantar repeaters while sending their CWID (internal from the Quantar no external controller)

there is a side tone of about 400 HZ low modulation that is send in conjuction with the CW ID this is a bit annoying

Has anyone saw this ? what is the solution ? is it Hardware problem or Firmware ? ar mabe configuration

I have heard here and there that the CW is clear but it is only few times I have noticed this

Thanks Forward
