    Does the Ten Tec Eagle have any kind of visual zero beat indicator? What about the Kenwood TS-590S?

    I haven't had a chance to use either rig and was just curious whether one or both of them included this feature.

    Not very responsive to your question but I would think the beat sound technique of zero-beating would be far more precise when done properly. The problem is some folks don't seem to know how.

    I'm comfortable doing it either way, but like having a visual indicator as it is a little quicker in my experience. And the one on my FT-950 is very precise.

    For rigs not having some visual zero beat indicator, you can always run a waterfall spectrum program on the receiver. Use whatever spectrum display program you like. Perhaps one you already use for digital modes. Merely adjust the tuning knob to put the received CW tone on the right frequency.

    I also like the one in the FT-950. The problem with doing it the old way is that you can vary the transmit offset frequency in most of these new rigs and that opens up a whole new can of worms. With the narrow filters that everybody uses these days (especially in a DX pile up and in contests), it doesn't take much at all to be out of the other stations passband.

    I'll second this method. I do have the FT-950 but for me, I find using the waterfall a lot faster since I usually have dm780 already running for the digi modes. Most of the time I just click on the signal in the waterfall then click the green C in dm780 to center it for me, don't have to touch the tuning knob at all that way. I don't think it gets faster than that.

    I actually like touching the tuning knob. I spend just about all of my work day in front of a computer display and so I try not to use one when I'm in the shack....I just gotta give my tired eyes a rest.

    Could you elaborate?

    Tuning the dial is required in both instances unless you are computer controlling the rig and offset. Having done it both ways, I don't understand how using two or more controls is easier than one (your ears). I'm of course discounting the pitch offset as that is a self-inflicted complication. Am I missing something?

    Well, honestly, a visual indicator might not be easier for you. I find it which I guess I really mean "quicker" use a visual indicator because, if I'm working with my ears only, it usually takes me a little while to tell when the tones are in zero beat. I have to really focus on the tones and not on anything else I may be hearing in the background (static crashes, etc.). Not a big deal. In fact, I don't mind doing it by ear at all to tell you the truth. But I'm a little quicker when I use a visual indicator. But I wouldn't necessarily expect what's easier for me to be easier for others in this area.

    Rigs do this in different ways, and I think the visual indicator is pretty slick. My little FT-857D mobile rig has one, it's just an LED up on the top of the front panel.

    Ten Tec rigs have a SPOT button on the front panel. You tune someone in, then hit SPOT and turn the dial until the tones match (zero beat) and release the button. That works very well and can get you within a few Hz very easily, but it takes two hands to push the button and turn the knob.

    In a "rapid fire" situation like a contest, I don't bother using that. I just set the IF filter to 150 Hz, which is pretty narrow, and tune the station in to a peak; when I transmit, I'm within several Hz of that frequency, which is close enough. That only takes one hand.:p
