A splatter control circuit (28) for a noise blanking receiver (10) includes a SAW filter (40) having an output (115) in a main signal path. A noise blanker (27) having a control input (86) and a signal input (128) connectable to the input of the SAW filter, and an output (58), produces at its output signals received when no noise pulses are detected and the blanker switch blanking the SAW output when a noise pulse is detected. A level detector (80) having an input connected to the output of the SAW filter and an output, the level detector producing a signal at its output to stop the blanker from blanking at its control input when the SAW filter passes a signal above a predetermined level.
