Voice frequency speech output cannot be turned off. We do not have a workaround for this in the W4MQ software at this time, but it is on our “to-do” list.
What if I want to hear the speech frequency announcements, but the band is busy/noisy and I can’t hear them?
TIP: We have turned the voice frequency volume down, but you can hear it more clearly if you set the RF Gain down. Be sure to turn the RF Gain back up again so you can hear the receiver.
