Followed by DV testing, conducted C4FM test for tone signals.
Simply put, no difference with DV mode that I have done the other day i.e. no-good tone was demodulated at the other end. I tried both DN and VW mode --- but no difference was seen(heard) this time.
I am not a specialist on this area, but if I am allowed to drop a comment on this, it could be some challenges while we are going to send CW onto DV or C4FM modulations.
My thoughts are, it could be related to DVSI's high compression algorithm to achieve very narrow BW optimized for voice. Someday, I wonder if I could hear their answer.
Thanks for this place and your time. I just wanted to share interests on "morse" whatever on the mode.
