Stereo Tool

Hello,
I’d appreciate it if you could answer my question.

I’m using a Pira Tuner to measure over-the-air broadcasts. Although the audio, RDS, and pilot levels are normal, I can’t seem to reduce the Noise/AM (Alternative Modulation) value. Even though my RF level is good, the signal quality in the top-right corner of the device remains at 3-4 bars and doesn’t reach full. Interestingly, with other radio stations, even when the RF is low, the signal quality is perfect.

Do you have any recommendations for Stereo Tool?

Is the low signal quality on the Pira and the high Noise/AM value significant for modern radio receivers?
