David, the Clifton lab's Si570 kit could work with the Minima, but the automatic filter switching, tuning, T/R, CW etc won't work. You will be better off spending an evening hooking up the Arduino instead. Mathematically, CW generated as single tone of SSB is no different from a pure carrier. It is just a way to generate CW. Perfectly legal. There's no way to differentiate a pure carrier from a single tone SSB. - f On Tue, Jan 21, 2014 at 5:14 AM, Steve VK2SJA <vk2sja@xxxxxxxxxxx> wrote: > Hi Dave, > > > Is CW operation an SSB Tone, rather than actual carrier?
