[Elecraft] [K3] Width Control and AF Output Level

One of my friend K3 users report that AF output level with 100Hz passband width is lower than with 150Hz passband width. He also reported that a noise like “Ptsu” was generated on reducing passband width from 150Hz to 100Hz. He had guessed that these were specific to his K3, but some other K3 users including myself reported the same.
Some extreme users who use this narrow passband may have been bothered by this reduced AF output level and noise. If the AF output level change is caused by K3 DSP filter design or program, adding automatic gain compensation feature to keep same AF output level would be highly welcome.
