Arduino antenna tuner In this version I swapped the coil with a new, somewhat larger one, which has an extra connection about halfway. This capacitor forms a simple L-tuner, together with an inductor which you can't see The Arduino Sketch (source), Android source code (Eclipse project) and schematic can be downloaded on: https://github. Before we get deep into the project, I intend to outline what a magnetic loop antenn… The Arduino board is a fantastic tool for rapid prototyping, and can help radio amateurs in lots of homebrew projects. In each position, the capacitor makes a Jul 16, 2015 · Hello group, I am new to Arduino, like most I have purchased a couple Arduino's, and some different shields. The SWR meter (in the back) is hooked up to the Arduino, also a servo is attached which drives a capacitor. Using a relay (controlled by the Arduino) the inductance can be switched between half and full. By varying the load, it can find the ideal matching for the given antenna and frequency. Magnetic Loop Antennas are cool for size constraints, but suffer from low bandwidth. When the AutoCap application on the PC wants to move the motor on the antenna, it sends a simple text-based command to the Arduino unit, containing the details of the movement action required. Feb 1, 2018 · Arduino Antenna Tuner Last updated: 2018-02-01 Introduction This project is in BETA status. MagLoop Tuner does exactly that, by having a set of calibrated values and estimating the variable capacitor position for each frequency change. Apr 27, 2012 · This is version 2 of my demo for an arduino antenna tuner. Mar 31, 2012 · Ok, this is just a concept, I just wanted to show how the Arduino could be useful for radio amateurs. Jan 17, 2017 · A homemade semi-automatic antenna tuner for HF controlled by an Arduino Nano. the RF matching circuit is a going to make and automatic antenna tuner based on arduino and using economic card this atu project can be installed outdoors and controlled remotely by an rs485 link. This is my Arduino controlled antenna tuner for ladderline fed antennas. About Arduino-based Automatic Amateur Radio Antenna Tuner arduino amateur-radio antenna Readme GPL-3. If you didn't guess I am a ham. I have play a little bit with sketches, read lots etc My project is a remote antenna tuner. The antenna is a 33' vertical, but in order to make it a multi band HF antenna i need a means to remotely tune the antenna. It uses an arduino nano, which saves stepper motor positions, and relay settings to Jan 6, 2014 · To automate tuning, an Arduino switches a bank of capacitors and inductors in and out of the circuit. It can be either directly connected to a radio by this project describes an arduino based automatic antenna tuner for an end fed half wave efhw antenna working on 20 40 meter bands. Listed under the Technical Reference/Arduino category that is about Ham Radio - Arduino Projects. com/pu2clr/Antenna_Tuner_Android_Arduin Apr 25, 2015 · Arduino automated antenna switch, CW Keyer, Automatic Antenna Tuner, RF PWR and SWR Meter, APRS Tracker, Beacon Controller, antenna switch, Rotator Controller, Arduino as an SDR. Aug 5, 2024 · The tutorial of a DIY magnetic loop antenna for the amateur radio band featuring a remote tuning system implemented on Arduino with a RC servo. An automatic tuner could solve that problem by re-tuning the antenna whenever the frequency is changed on the radio. It features: Balanced and unbalanced output Support for “true” balanced L-C-L matching networks, or floating ground Optional LCD display Lock switch Tune button Receive bypass Regular and Latching Relay support through the use of hardware control macros Magnetic Loop Antenna Automated Tuner: Hello community - Dave here (radio callsign G7IYK), I am very pleased to publish details of my latest project which is a magnetic loop (ML) antenna automated tuner. Arduino-based automatic antenna tuner I've been looking for an inexpensive antenna tuner with a roller inductor for a while -- "inexpensive" is why I've been looking for a while. Apr 9, 2014 · The PC connects to the Arduino using a virtual serial port provided by the Arduino device driver. This project describes an ARDUINO based automatic antenna tuner, for an end fed half wave (EFHW) antenna, dual band for 20 & 40m. Aug 20, 2019 · If you work a lot with arduino's you might run into this very annoying problem that com port numbers keep changing with each upload The solution is to make your operating system forget the previous serial devices that have been plugged into the USB port. I wanted to demonstrate that it is very easy to build an automatic antenna tuner with the Arduino. 0 license Nov 4, 2011 · The Arduino board is a fantastic tool for rapid prototyping, and can help radio amateurs in lots of homebrew projects. larvx qwu djov yhocrz fwd iqlfo vljmg smvkydv fidl gegzans pbyae vpojgt gxjje diz zcorzdhy
