Tom Hall does amazing things with solder and electrons in the heart of New York City. I give him extra credit for doing this on the island of Manhattan because 1) that's where I'm from and 2) EVERYTHING is more difficult there.
I may have presented this video before. If I didn't, I should have. And if I did, well, here it is again (I guess my NYC attitude is showing here).
Look at the ease with which Tom switches bands. Fantastic! But even more important, LISTEN to the quality of the reception. Listen as Tom tunes in on strong CW and SSB signals. Do you hear any signs of the dreaded phase noise that is supposed to plague the Si5351 chip? I do not. I think this receiver sounds great.
I don't know why the Si5351 got such a bad rep for noise. Could it be that some people were testing it with boards other than the Adafruit or NT7S products that we have been using? Could it have been that in the tests the boards weren't completely installed? (It is important to have the VFO and BFO signal lines properly shielded.) Could it be that in the tests they were using physically adjacent clock outputs from the board? (We use CLK0 and CLK2, skipping CLK1 to avoid the "bleedover" problem that was noted by early users.)
