treble only SSB modulation


Hi there uBitx owners,

today a ham confirmed me that my modulation was only in the treble part of the audio spectrum: no bass and (that the most annoying) no medium frequencies to hear...

I wonder  if this a known and common problem, although I was not able to find something related while browsing the group's messages.

For information, I just use the electret mike as delivered with my V3 board.

Any comments ?
