MMDVM_RPT_HAT for GPIO

Post by M0MCR »

Hi everybody,
I have the above board in a repeater setup running with 2 x GM340 radios. The system is functional and almost to the point of going online, but from the testing I have done it seems the output audio as received by listening stations is a bit too low, and they need to increase there volume. They do say the audio is clean and clear with zero packet loss and Zero bit error rate.

In need to find out I can increase the output volume.

Any hep appreciated

You are after the settings located in the configuration, extra, mmdvmhost scroll down until you see references to each mode and a level (think they are all set to 50 as default) be careful with this setting as it will affect the overall deviation and you shouldn't go beyond 2.75KHz otherwise you will be going outside the specified levels for the digital modes
