Re: Ubitx microphony

Hi Alf,toggle quoted messageShow quoted text
It is entirely possible for the vibration from the speaker to rattle the microphonic parts on the board. Remove the speaker from that equation by using an external speaker at some distance. That will remove the speaker vibration induced microphonics and expose any remaining distortion from an overloaded amplifier that is probably clipping. If the speaker is causing some distortion on strong signals as you have described that would be in addition to clipping.
Turn the volume down to reduce the clipping. Use the external speaker to reduce the microphonics:)
