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

    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.

    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.
