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.

CAT Support uBITX Firmware CEC Version 1.06 Release (Added WSPR)

uBITX Firmware CEC Version v1.06 (changed v1.061)

I deployed 1.06 and received feedback from WSPR's beta tester, Philip (G7JUR).
It was a problem that the LPF was not automatically selected according to band selection during WSPR transmission.

Version 1.08 has been released.

I modified it soon and changed uBITX Firmware CEC Version to 1.061.
uBITX Manager also changed Version to 1.01.


I released version 1.06 which added WSPR function to uBITX.
Beta testers have been very helpful when embedding WSPR functionality. WSPR will continue to improve in the future.

By using WSPR before and after QSO, you can check where your uBITX is spreading all over the world.  If uBITX Manager is used to put WSPR information into uBITX, uBITX no longer needs any external device to transmit WSPR.

The uBITX group's excellent tester also shared a …

CAT Support uBITX Firmware CEC Version 1.01 Release(Changed from v1.0)

CAT Support uBITX Firmware CEC Version 1.01  Release (Changed from v1.0)

uBITX Firmware CEC Version 1.06 has been released.
Please click the link below.

This version of the concept is an upgrade without hardware modifications. No hardware modifications are required to use this firmware. Continuous release and testing has been done in the uBITX group. I tried to put only the basic functions that an HF transceiver should have. The features have been upgraded with the advice of people who have great ideas in the uBITX group.
It was a project that started to contribute to the original source in github. The project was intended to fix some simple bugs and request merge to the original source. And I was planning to delete the project. At the beginning of the project there was a bit of discussion about this in the uBITX group.
Since then, I've keeping the original source type to allow code share with any user fork…
