Are you sure you're doing this right? You need +5V power on pin 40 relative to pin 20 (GND). Then confirm you have a strong 5V p-p 6 MHz clock signal on pin 19 and a weaker version of the same signal on pin 18.
Maybe check the good DME to confirm your scope is set up properly to detect the 6 Mhz signal.
