Is the radio working without any excessive hum now that you have replaced R17. If so dont worry about the screen.
Is the other coax cable screen connected to chassis? Only one of these screens need be connected to the chassis, if both are connected to different parts of the chassis then sometimes it can introduce an earth loop which can cause problems with hum.
