It’s not the type of cable, it’s a fault in how one is made. RF interference is a pretty nasty subject, and you need some specialist knowledge to work it out, but you need to determine what type of radio you are hearing as this sets the cure. If you live in an area that has an active AM radio station locally, then this can be demodulated by the components in many studio kit, but a preamp, taking tiny signals and processing them is a likely culprit. However, as a cloudlifter is a phantom powered device, if the ground was missing, it wouldn’t work. It is possible the cable is miswired and the shield is not connected to pin 1. Oddly as long as the wiring is 1 to 1, 2 to 2 and 3 to 3, it will work, but be lacking shielding. Obvious things to check are substituting cables. See if this makes the interference go away. If you do not have an AM station nearby, the source of the interference is less easy to determine. Can you identify the station. If it is not a local one, then it could be much harder. I had one once where I could hear a BBC local radio station through a PA system, but this ‘local’ station was from another part of the country. It was tracked down to a loop system in a bar next door, that was fed from a long forgotten about computer fed from the net. Somebody had cut through the cable and this was spreading via the mains wiring.
start with removing and swapping cables methodicall, one by one and report back.
