It is up to you to make the next advances. but they are passing.Īs a nation, we look to you to make the next innovations. People, in the developing years of these industries, did HUGE things that forced us all forward into the future just as we hoped…. Your progenitors that taught you are passing…. A very early computer mainframe programmer which you didn’t even know existed at the time… There are two HIGHLY noted aviators, one and aircraft designer of world record, still active and producing world records. That being said… others of his family also went into other electronics and technical studies. It is wished this continue for him in peace. The ONE of incredible note is of advanced age and living comfortably and peacefully in the same home where he first climbed WPDR’s mast to replace the lamp, and was hooked, and became one of the most influential members of the industry. There is a already a well established and fully replete history of the radio industry including their names in this State. It sounds like I’m trying to drag out some fame or association for myself, but this is not the case. My own family history is replete with radio “hackers” having risen to the highest levels of not only the hobby but the industry itself and dominates in the Southern half of this State.

If you want an antenna analyzer for $40 (or less, if you have a good stock of parts) this looks like a worthwhile project. Even so, he warns that readings higher than 1:1 VSWR are only accurate to 10% or 20% – still good enough for ham shack use. After plotting the values with known loads, broke the diode operation into three regions and used different equations for each region. One interesting feature of the Arduino code is how it deals with the nonlinear nature of the diodes used in the circuit. There is another version of the Arduino code that drives an OLED screen, although you still need a PC to kick the process off. Since this is a no frills, unit, you are expected to grab the output from the Arduino and manually put it in a spreadsheet to plot the results. It’s always easier to move stuff around on the screen than on the perf board. Since placement can be important with an RF circuit, this isn’t a bad idea. Although the build is on a universal circuit board, used Eagle to lay out the circuit as though it were a PCB. The design is rooted in another proven design, but changed to take advantage of parts he happened to have on hand. Unless you are a big time antenna builder, the unit will then sit idle on the shelf (or will wind up on loan to hams even cheaper than you are). As he points out, you probably only need an analyzer for a day or two while you set up an antenna. So it is no surprise that hams like will build an antenna analyzer from a DDS module and an Arduino instead of dropping a few hundred dollars on a commercial unit. Most people, however, just see them as cheap. If you are a hacker, you might consider ham radio operators as innovative.
