Sounds like the converter is generating RF interference. :)
Are you seeing this problem with AM or FM reception or both? I am working a somewhat related problem with AM reception issues on our TT. The converter is definitely a source of RFI that appears to affect the radio's automatic gain control circuit causing it to reduce RF gain and hence volume. There are other RFI sources such as the fridge when operating on gas for example. If you see this problem on FM then it is probably not an RFI issue.
