Hi.
You would need to use a x10 probe and look at the waveform on the IF amp grid. Adjust the scope so you can see the audio clearly in the carrier. If you see bits missing in the middle of the carrier it is overmodulation most likely from the transmitter. Compare it with a nice clear station and you should see the difference.
