Forgetting the ham radio modes which I can easily ID ( or tell what type mode it is ) & receive ,what is the mode that sounds like a buzz saw that I hear in various places day & night on HF ?
Right now at 12:30PM PT I'm hearing it on approx. 12.894 USB.
There seems to be many websites that have samples of ham radio digital modes ,are there any websites that have samples of the other digital modes used on HF beside ham radio modes. So I can at least tell what type mode it is that I'm hearing.
