Older mice (the ones with "mouse balls") used two rotary encoders to sense and count movement in two directions.
The P3 uses a single rotary encoder and a knob to position a vertical line on a horizontal scale. The same encoder is used for P3 menu selections. A mouse is but one kind of "pointing device". Currently the most common of course. 73 de Dick, K6KR Sent from my iPhone On Dec 26, 2009, at 11:28 AM, "Bob Tellefsen" <n...@comcast.net> wrote: > Thanks Fred > Happy New Year > Bob N6WG > > ----- Original Message ----- > From: "Fred Atchley" <hamkt...@att.net> > To: <Elecraft@mailman.qth.net> > Sent: Saturday, December 26, 2009 11:13 AM > Subject: Re: [Elecraft] P3 question > > >> As I recall some of the discussions at the Santa Barbara Hamfest, a >> mouse >> interface would greatly complicate the design of the P3.
