You are hearing this because one of your base station transmitters is disabled and the belt pack receiver is looking for a signal. If you still hear this after enabling the base station, the base transmitter may be mistuned.
Check the base transmitter “separate” and “combine” switch to ensure that the two transmitters are feeding the ports that you intend to use. If you are going into a TX-8 combiner, then you must place the switch in “separate” and connect both transmitter antennas. If you are using one transmitter antenna, then you must place the switch in “combine”.
Make sure that all base stations are in “Master” mode and make all settings. Connect the cable and cycle power on the base stations. If using one to five “slave” base stations, make all setting in the “Master” Mode then change to “Slave”. Again, cycle power on all base stations with the link/sync cables connected.
Keep all systems powered up and disable the base transmitters. You may be getting AM radiating RF onto your wired comm through poorly shielded chassis or cable. Get some distance between the base transmitter antenna and the wired comm cables and chassis. Also, use only the amount of RF power out of the base as is required for the task at hand. You rarely need to use 250 milliWatts.
The headset cable is the counterpoise for the VHF transmitter antenna. It must be connected for proper transmission from the belt pack
The belt pack locks to Channel 1 to ensure a closed loop system. Channel 1 must be turned on in the belt pack receiver. If you do not want to hear it, turn the volume control down.
