Notes:
MDS, blocking and two-tone DR measurements performed using the narrowest crystal filter setting. AM audio recovery tests performed using the widest bandwidth setting - about 12 kHz @ 6 dB down.
AM distortion numbers show the somewhat typical increase at lower audio frequencies - most often caused by the low audio frequencies riding on the AGC line. Also there is the usual increase in audio distortion as the modulation percentage increases. This is due to the detector's inability to cleanly demodulate the higher amplitude levels.
Thanks to W1MPY for use of this receiver.
