low-cost camera pan tilt for Amateur radio (First Test and First Modification)

I bought a pan tilt controller for the camera a few days ago.

perhap it's use for Amateur radio antenna, Especially, it seemed good to use it for the satellite antenna which requires not only the horizontal rotation but also the vertical rotation.

It will cost $ 150 and will be very successful if you can raise the satellite antenna.

It uses AC24Volt and is controlled by 485 communication. connected using the usb to 485 sold on the Internet.
The default protocol for this is pelco-D, and programs for pelco-d are easily found on the Internet.

I am developing a program dedicated to this and will release it soon.

1.First Test - Elevator test

The maximum angle seems to be insufficient.

2.Rotator test

The angle of rotation is very perfect. There is a limit setting part at the lower part, and if one is removed, it can rotate up to 360 degrees.

3.Simple Modification for Elevator

open pantitle

found Limiter for elevator - It acts to push a switch that prevents it from turning anymore.

Looking at the picture below, there is nothing to prevent rotation in other parts of the structure.

I cut (Sharpen) the limiter by the desired angle.

4.Elevator Test

The angle of rotation is very perfect. 
Lightweight yagi antenna for satellite communication seems to be able to control enough.

 Now I only need to pick the right antenna.


  1. SInce it is meant for a camera, wouldn't the antenna need to be very light and balanced at the mounting point?

How to upgrade uBITX Firmware

uBITX is based on Arduino Nano. So uBITX's firmware upgrade method is the same as Arduino.
There are two ways to upgrade the firmware of uBITX.

The first is to compile the source from the Arduino IDE, and the second is to upload the compiled hex file using the Firmware Upgrade Tool.

I'll show you how to upload a compiled hex file as a second method.

1.Connect the uBITX's USB cable to the computer.

2.Run Device Manager on your computer.
  The way to open the Device Manager for each OS Version differs slightly.
  In most Windows, you can easily launch the Device Manager by running.

  On your computer, press the Windows key + R.

 Type devmgmt.msc and press OK Button.

On most operating systems, there will be a serial port named Ports with CH340. If so, the next step is skipped.

If the serial port is not installed as below, you need to install the driver.

Included in uBITX is the Adonano, which uses the CH340 USB To UART part.

Download the latest CH340 driver from the Internet.
