Arduino antenna tuner code#

So far, I have written Arduino code for positioning the capacitor and the inductor, checking the limits, slewing slow and fast, stopping at the limits, going to a specific position, etc. This makes possible the six wire interface. The two motors and the meter readout are multiplexed based on which joystick was last pressed. The voltage is ratiometric to the Arduino's 5V supply, so is also read by the Arduino's AD converter and used to stop rotation of the respective shaft as the capacitor reaches min and max capacitance, and the inductor reaches the limit of its travel. The blue readout is just a voltmeter that shows the pot wiper voltage of whichever joystick was last pressed.

Holding the joystick for more than ten seconds causes the gearmotor to slew at full speed. Holding the joystick for ten seconds steps once a second. Tapping the joystick makes one little step up or down. The left one controls the capacitor the right one controls the inductor up to increase capacitance or inductance down to decrease, respectively. arduino servo arduino-firmware antenna antenna-tuner Resources. So far, the control box just has two center-off switches (joysticks) for testing. Here are two pictures of my breadboard (literally) as it exists so far: Goal is a hands-off remote tuner, and to get to learn more about what I can do with a $3 Arduino Mini. Even at a 1kW power level, the maximum voltages are manageable at < 3kV and the currents are < 3A on all bands of interest. The 18ft whip doesn't resonate on any ham band, but can be tuned without switching the configuration of the tuner. One trick I learned is that making the vertical antenna element 18ft long allows it to be tuned with a series-C input, shunt-L from whip to ground tuning network without having to reconfigure the network on any band from 20m to 6m. Will store the settings in EEProm during power down. I am going to use memorized (band-dependent) positions to preset the tuning to the same positions where the best match was found the last time I tuned that band as this tuner will always be connected to the same antenna.

With the AA-30.ZERO, dreams of radio amateurs are coming true!įor specifications, connection examples and software, please refer to the menu at the right side of this page.A directional coupler (to allow the Arduino to measure SWR) will be used for the final positioning of the L and C. Connect the antenna tuner to the jack and power up the Tuner Dipper. It features a balanced output and switched capacitor and inductor banks and can handle 150 wat. There is no chance to find such powerful competitor analyzer for such a low price. ♜ontroller Arduino Information HF Projects VHF Projects Antenna Projects APRS Projects CW Projects Junk Box Circuits. This is an Arduino controlled HF amateur radio antenna tuner.

Want to tune your antenna with driven elements? Use the AA-30.ZERO for fine tuning. Want to perform RF-circuits or antenna analysis remotely ? Pair the AA-30.ZERO with the ESP8266 Wi-Fi SoM and do it easily! DIY Arduino based Automatic Antenna Tuner How about building your own smart-tuner This is L-C-L matching network antenna tuner build and. Want to make your own automatic antenna tuner ? Use the AA-30.ZERO as a replacement for the directional coupler! Also, we have made available several examples of running the AA-30.ZERO in DIY projects. The AA-30.ZERO is perfectly compatible works our AntScope software.Įxperienced users may pair the AA-30.ZERO with Arduino boards making their own hardware/software project, since the AA-30.ZERO is compatible with Arduino standards.
