Re: uBitx Easy-Digi Strange Output ?

Hello Chuck,

I saw the same thing on my V3 board.

First I checked that my BFO adjustment was correct and it was with the low frequency cut at just below 500Hz.

The xtal filter was in fact too narrow and cut at about 1800Hz too like you are seeing.

That led me to change C217 to C221 from 100pF to 82pF and I now have au audio passband from 480Hz to 2400Hz.

But check your low frequency cut off first to make sure it is not a BFO adjustment issue.
