    Why is there no sound from my Icom IC-M88 speaker?

      Jeffrey HigginsAug 17, 2025
      There might be several reasons for the lack of sound from your Icom Transceiver's speaker. First, the squelch level may be set too deep; try adjusting it to the threshold point. Second, the volume level could be too low; increase it to a suitable level using the [VOL] control. Finally, if the speaker has been exposed to water, drain the water from it.
