![]() The AD9850 is controlled from an Arduino Micro microcontroller, and is used to generate sine wave outputs from 1MHz to 30MHz. The basic design uses an AD9850 direct digital synthesis (DDS) module to generate the testing output signal. PDF of testing results for breadboard version of the analyzer. The results from this test (as a PDF) are in the link below and gave me enough confidence to proceed with my project. I first constructed the unit on a breadboard, using a couple of germanium diodes and an Arduino Uno I had on hand to make sure I had the circuit correct and that it functioned reasonably correctly. □īut I did spot the K6BEZ Antenna Analyzer, and it piqued my interest. ![]() Had I been aware of this unit, I probably would have just bought one. I am also working on a so-called “magnetic loop” antenna, so I realized I was going to need to be able to analyze its impedance, and to tune it, so I started researching antenna analyzers online.Īt the time I had not yet spotted the “Nano Vector Network Analyzer” units available on Amazon and eBay – they didn’t show up on a search for “Antenna Analyzer”. ![]() Discussion of using a balun as an unun online at.I found Nooelec’s support exceptional – and indeed they ended up refunding the price for the unit, though I felt that was not necessary for them to do. But there is no reason why a balun cannot also function as an unun, as near as I can tell. I had some questions about it because it indicated it was an unun (unbalanced to unbalanced device), but when I received it, I found it could not be wired as the typical autotransformer style unun. Adding a Nooelec 9:1 balun (being used as an unun) increased signal levels some due to a better impedance match, but did not help the signal/noise ratio at all. I find it does not work that well – largely, I think, due to noise. Information on the original can be found at : Īfter dragging out my Sears-branded Yeasu FRG-7 shortwave receiver, I strung up a “random wire” antenna. What's more it is constantly being updated and upgraded so as long as you're paying a subscription you'll never have an out of date version.Note: Information on the original design (c) 2013 by Beric Dunn, K6BEZ, is licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported. The software allows musicians total control over the recording mixing and production of their music. There is also a comprehensive range of effects which can be used to transform the sounds of those instruments. There are numerous instruments which enable the user to build entire pieces of music from the ground up. The interface is designed to resemble an analogue console so you are given a selection of faders switches and swinging needle displays. It is designed for people who have the time to really sit down and make the most of it. Serious softwareĬakeWalk SONAR is not something that you can just download and very quickly start making complex music with. There are different levels of membership which have different price points depending on what exactly you want to achieve and monthly subscription is an option. CakeWalk SONAR is a digital audio workstation (DAW) that offers innumerable possibilities for anyone seeking a way of making music on their PC. ![]() For amateur and professional musicians alike ever-advancing computer software has provided exciting opportunities for experimentation and development.
