[Boatanchors] HBR Receiver BFO Question

[Whitebear1122]

Hi, I am working on the HBR-13 build.  Just finished the BFO and have powered it up separately.  I have a question regarding the output waveform of the oscillator.  While I scope out the grid side and get a nice sine wave, the output of the BFO is not symmetrical.  It’s on frequency, it sounds fine, but it’s not a sine wave anymore.   I tried submitting this post last week with a small photo but it never came through. I have a photo that I can email.  What is the BFO output wave shape supposed to look like?  Is it supposed to be a sine wave?  Thanks, 73, Scott WA9WFA
