Timer/Alert volume

Is there anyway to make the timer alert beep/alarm louder? I have it set to 10 but I'm running past my timers cause I can't hear the beep. It's very quiet when it goes off,maybe a different speaker?

Does your tx have a vibrate option like the Devo10?

You could fit a head phone jack and wire it up between the circuit board and speaker so when headphones are plugged in power goes to the headphones instead of the speaker.

I have the devo8s,I don't believe it has the vibration option,the buzzer is just so quiet.
