Receiver sensitivity is around -50 dBm over the broadcasting AM band (525 – 1500 kHz) with more than 10 dB (S+N)/N ratio. Noise level is around -65 dBm.
Compared to the Atwater Kent models 20 and 20C, with similar components, the receiver sensitivity is reduced with at least 10 dB, even if 6 tubes are used instead of 5. The problem is the alignment of the tuning circuits with a single mechanical control. In practice, for a perfect tuning, there are few % variation from a tuning circuit to another, in special in the first stage where a certain antenna tuning is preferable. However, an easier tuning is done with the model 30 than with previous tree dial models.
