Re: Distorted RX audio at higher volumes #ubitx-help

 

As you may have read that the volume control wires are incorrectly shown in the wireup diagram.

Please interchange the yellow and red on the volume control. This may solve the problem.
If it becomes worse then there is some other problem..

On all my boards I changed R51 or equivalent (in Bitx40) to 2.2K and even 1K and got much better
audio on strong signals.

Hi All,

My uBITX has arrived and went together with no issues. I have a question about the audio stage and a potential issue with my uBITX.

At LOW volume levels, the RX audio is smooth and sounds great, however any volume setting above roughly 20% starts to distort badly, and sound horrible. Therefore I have the leave the radio volume set very quietly to use it.
