Glen Popiel, KW5GP, author of the newly released ARRL publication Arduino for Ham Radio will be the featured guest on a webcast on Thursday, October 30, at 0100 UTC by Tom Medlin, W5KUB. Arduino devices are powerful and inexpensive microcontrollers, and they are an easy way for radio amateurs, students, and professionals to create devices that interact with their environment through sensors and…

The Arduino has become widely popular among hobbyists and ham radio operators. Hams are exploring these powerful, inexpensive microcontrollers, creating new projects and amateur station gear. With its Open Source model, the Arduino community freely shares software and hardware designs, making projects easier to build and modify.

A video showing my DSP audio processors. 🙂 JC
I was messing around with my Arduino board and figured out how to make a cheap portable electromagnetic field (EMF) detector. It only requires a led, 3300000 Ohm resistor, and wire. As I approach an EMF the led gets brighter, so I can locate the source. Messing around with the code and resistor values I can change the sensitivity of the device; when I first made the EMF detector I could only find one place to stand in my apt where it didnt go off. I am working on getting a commercial EMF detector that spits out quantitative values so I can calibrate my version and have it do the same on a LCD. *UPDATE you can decrease the sensitivity of the device by making a loop with the antenna. Also the code can be found on my website, aaronalai.com
First experiment with an arduino and a servo with a variable capacitor connected to a Tp-Link Ps310U through ethernet. Power on Ethernet. Fast and fine manual tuning with a Griffin Powermate. It work very well! Also mouse wheel work. Pc software writed with AutoHotKey

ATSC Centronics antenna tuner installed! Connected via the componant ports. Set can display in 1080i when a 1080i signal is present. Works great and I show the main features of the antenna tuner. The HD on the Sony Trinitron is fantastic. Free TV is back baby!! I’m approximate 20 miles from most of the transmitter towers. The stonger staions work verywell at night. Lets say after 7:00 PM. In the late afternoon, I get pixallation and drop outs. I think perhaps due to cars going by

First test with Arduino tuner. The Lock button on FT817 is used to tune the capacitor. On 20 and 40 meters (actually) there is a fast tuning function. On different frequencies all the capacitors course are analyzed to find better SWR. Arduino is used to drive the servo,read frequency,swr and lock command from FT817 and set FM mode for tuning.At the end of tuning procedure Arduino set again LSB or USB depending the frequency. Based on Alain De Carolis project (alain.it)
This is a new Palstar AT2K tuner that I purchased, and I hope for it to be the last antenna tuner I ever buy. So far it’s living up to that reputation flawlessly. The construction is top notch, the level of attention to detail that Palstar has put into this tuner is stellar, and I wouldn’t hesitate to recommend this tuner to anybody, even with the most demanding antenna tuner needs.
This is version 2 of my demo for an arduino antenna tuner. In this version I swapped the coil with a new, somewhat larger one, which has an extra connection about halfway. Using a relay (controlled by the Arduino) the inductance can be switched between half and full. In each position, the capacitor makes a full sweep, while the Arduino monitors the reflection (watch the right meter in the back!). After this, it puts the inductor and capacitor in the position with the lowest SWR. This demo is quite slow, I experimented with different speeds and was able to let it tune within 2 seconds!

Ok, this is just a concept, I just wanted to show how the Arduino could be useful for radio amateurs. The SWR meter (in the back) is hooked up to the Arduino, also a servo is attached which drives a capacitor. This capacitor forms a simple L-tuner, together with an inductor which you can’t see on this video. The Arduino does a full sweep on the capacitor while measuring the SWR. It stores the position with the lowest SWR and after the sweep it rotates the capacitor to that position. Mind the SWR meter (right needle) while the capacitor is rotating!

www.hamradiofinds.com Here is a video showing the JW MIller AT-2500 HF Ham Radio Automatic Antenna Tuner..This tuner covers 80-10 meters & will handle 2Kw+ of power..It has one input & 5 outputs, including one long wire connection..It runs on 110VAC, but can be switched to run on 220VAC..The tank circuit is well constucted using heavy duty parts..This would make a great addition to any HF ham radio shack..Thanks for watching..73s, Mel, WA5UTK
