Physically moving cables around can reduce or even eliminate hum and or interference as you can often 'cancel' it out by having the 'interferance' out of phase. The root cause should be sought really because you don't want to have to tinker with wiring position every time you change ANYTHING!
The fact you have some radio in there is a clue as this should not be happening at anything like a level that interferes with line level monitor signals. Find out which station is broadcast and get technical details from them. A 100KW transmitter 500 Metres down the road will upset things.
Ferrite beads, rings, filters, foil on walls, metal plate the room, pull the nearby transmitter down, move house (studio), the list starts off cheap!
Actually, contact the monitor manufacturers as they should not be so sensitive to 'airborne' interference.
Good luck
