- I think the Omni 6 plus has all one needs for CW tuning. "I am tone deaf" is a complaint I hear. I can only say the proceedure for CW tuning is "zero beating" not "zero toning." The complaint of tone

- That's right. A zero beat means that the two tones are identical and so their vector sum is zero. Hence no output. Unless of course one does something odd with the phase of the two signals. Is that b

- To the contrary, when two signals are on exactly the same frequency the need not be out of phase, they can have any relative phase angle and when in phase they will add, when perfectly out of phase A

- You are confusing two usages of "out of phase": 1. having 180 degrees (pi radians) phase difference 2. not being in phase -- having a phase relationship of anything other than zero phase difference A

- Exactly - zero beat is when the "beat note" between the two tones goes to zero Hertz. Hence, zero beat. Musicians know all about this when they tune their instruments. 73, Duane Duane Calvin, AC5AA A
