Daiwa 801 series SWR/wattmeter


That is good to know. I am not a shop so I don't need spot on accuracy, but still would like to have a decent idea of what my equipment is doing. When I hook my amp back up, I'd like to be able to set it up with a good 1:4 swing ratio. I also want to make sure I am not over driving it too. No need to burn up my equipment because I am over driving it. I bought a Dosy a while back. It does fine for monitoring my SWR incase of a problem, or reading my dead key. But the peak reading is not even close. I am going to need something else.
 
I bought one also...newest version HP3...I'm happy with it...I think it's a little tight
One thing I don't like, you can't read swr in Peak range...
So I always check and set the tuner in AVG...then switch to peak mode
Other than that I give it a B+
All the Best

SWR is a static (non-varying) value: it does not increase when you increase the power unless there's something wrong with the antenna or feedline.

Inexpensive (okay, "cheap") SWR meters compare the reflected power with the forward power, without modulation. You have to adjust the meter after each power change or significant frequency change. There's no reason to measure SWR in "peak". Once properly checked it's not going to change unless, as I said, something goes wrong with the antenna or feedline.

If you are referring to my post about the Dosy, that is totally not what I meant. I have a Dosy. It reads 70W PEP on my Galaxy 95t2, that puts out somewhere between 100W-140W PEP. That means when I set my radio up for my amp, according to that meter, I will burn my amp because my radio is putting out much more than the meter says, so I need an active peak meter to avoid this from happening. It has nothing to do with SWR portion at all. I was stating that the Dosy is only good for monitoring SWR or setting dead key. It isn't good enough for measuring peak output, which is why I am asking about the Daiwa.

Unless you were commenting on the other guy's post about it not measuring SWR in peak mode.

Unless you have lab quality measuring equipment you wil never see the difference between the Diawa and a Bird. As I said before a Bird meter's reputation is mostly hype. I have used Bird meters in the past and I know of commercial broadcast equipment manufacturers that use them but they do not use them for their alleged super accuracy. They use them for their ruggedness and for the fact that they can easily be calibrated to a standard reference in order to maintain the accuracy that they have.That combined with the wide range offered by various slugs results in a nice rugged dependable meter.
