Hi again Well all seems well if you are getting a good wave at the flip flop output. Just a comment about your input wave forms yes the MF does show a second harmonic petty low and as you have said the MF version works OK. Please remember a square wave is in fact and infinite number of harmonic frequencies so this is not an issue the dominant wave is overwhelmingly the fundamental so that will be processed into a square wave by the Flip Flop. If the drive to the multiplexer is good as you say (I can not open the JPG but it doesn't matter) it sounds like the local oscillator divider chain is correct. I can only conclude the instability reported is at the oscillator suggest you concentrate on that as a source of your problem. ..... I have run out of ideas. Anyway good luck and please report the solution there are a lot of people very interested. 73 petefmt On Fri, Jan 26, 2018 at 10:16 PM, Chris Wilson <[email protected]> wrote:
