This video presents a Magnetic Loop antenna controlled by an Arduino. The controller system receives a command via infrared transmitter similar to a TV remot…

Here is a brief video demoing the Kenwood AT-250. I am tuning a 2:1 SWR test load.

I am having trouble making a reply
Hi Bill. I have the same problem about right combination. I have tried to
take scraps of toys, computers and printers. But this is not the best way.
Thanks for the comment. 73. PU2CLR.
Youtube refuses my post giving a decent reply and the links to the gears
I posted my last weekend project about this subject on github/pu2clr.
Nice, will have a look at what you did.
I was thinking of doing a very similar project for my Yaesu FRG-7700. I
need to build the magnetic loops antenna first and then do the remote thing
with my NetDuino Plus, but use servos from RC airplan to move the antenna.
Cheers!
Thanks for the comment. I think you will like my weekend project “Automatic
Antenna Tunner with Android and Arduino”. I changed my project from IR
remote control to a Android Mobile Phone. I also introduced a QRP SWR Meter
to the System. See it in my videos
Good Job. I enjoy programming PICAXE micros and the Arduino. After
gathering a box of old stepper motors I was able to drive most of them
fast/slow/forward/reverse without problems. An old battery powered electric
screw driver is very strong for a low voltage motor, excellent for Linear
actuators too. However, I always have trouble finding the right combination
of gears to transfer mechanical energy, this seems to be a stumbling block.
Good Luck. Bill acj
That remote looks like the one that came with my Newsky TV28T (Elonics
E4000 & RTL2832U). Nice project, looks like a lot of fun.
My first prototype of Antenna Tuner controlled remotely for Magnetic Loop.
It was made in October, 15, 2012.
