[Elecraft] K3S Speaker sound question

[Jerry Moore]

Is this normal for the K3S speaker to sounds like this? I've not had the
radio long but not liking the buzzing in the speaker. I usually use my
headset but since attending Morse Academy I've been using the speaker more.
Thanks in advance.. The video is still rendering so it may not be
immediately viewable/hearable.
