Re: [uBITX] How to adjust CW sidetone volume? #ubitx

Rod Davis

Hi Dean,

Just yesterday I changed R250 (the input of the low-pass network for the sidetone) from 1k to 220k, and my sidetone is comfortably low at full volume.

100k probably would have been better, as the sidetone is a bit weak.

I only had 0805 parts, but they fit just fine on 1206 pads. No worries.

Good Luck,

Is it possible to adjust the CW sidetone volume in the uBITX?  I'm finding that if I have the volume turned up to hear a weak station and I hit the key to respond, my sidetone will be ear-splitting.  Any easy way to fix this?
