I also agree the with the timer volume problem on the 7C. If Futaba cannot increase the volume, can you come up with a replacement device (a simple piezo beeper, I would think) that beeps at a lower frequency. It's the high frequency that's as much at issue as the volume. I can hear lower frequencies. If you can recommend a proper lower frequency part, I can do the modification myself if Futaba will not.

Please, help everyone with this problem come up with a solution!
