I havent covered testing the SWR bridge circuit yet, so thats next. I have divided the sweep into 3 bands, 1-10 MHz, 10-20 MHz and 20-30 MHz. Yes that is correct. The code on the blog works with the vk3yy/kn5ute software.
The input voltage to the Arduino board when its using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). Cheers, Glenn. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. Your time in production and sharing is greatly appreciated. In the next article, Ill show how to drive the analyser with the driver software, and hopefully resolve the noise issue. The result is pretty good.

Update 2014-10-05: The analyser was hooked up to the SOTA End Fed Half Wave to see how it looked. When building an antenna say, for example, a dipole you cut the legs of the dipole according to the usual formulae relating wavelength, frequency and cable velocity factor, erect the antenna, feed it appropriately, then plot measurements of the SWR across the band, using a SWR meter and graph paper.
