I was looking into an active peak meter but can't afford a bird. I was wondering if anyone had any input on this meter? I am interested in its quality and accuracy.
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.
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.
