Lyman, I will do it. I would love to have one of those guys, but right now I can't afford it. I have a Autec WM1, Computing Wattmeter which reads SWR, and Power average and peak in 3 scales, 20, 200 and 2K watts. It does read correct peak power, and works well with the SDR1K but doesn't have any other bells and whistles. It costs a little over $100 when I bought, which was several years ago.
