After several videos were released showing the 10M SSB transceiver as heard by an SDR, I received some inputs that the only way to test the signal was using white noise Introduced into the microphone circuit. So that is what this video shows.
I see a couple of things in that the filter bandwidth is close to 2.8 kHz and that there is not a hole in the midrange. The white noise shows a drop off of the low range. BUT the Microphone circuit is full output below 200 Hz. But the microphone is a close talking noise cancelling job you know (that is a Big 10-4 Good Buddy) the kind so that may be skewing the results.
So, in all I would suggest lets get it on the air and the SDR Police will soon tell me things even I didn't know.
