Yesterday I have implemented emulation of keep-alive messages on server side. This means that the keep-alive messages sent by the front panel roughly every 100 ms are no longer sent over the network; instead, they are generated in the servers main loop with 150 ms interval.

In my first post about the IC-706 remote kit I wrote that we don’t really need to care about what data protocol is used between the radio and the front panel; all we need is to route the data between a serial port and a network socket. However, it turns out that taking a closer look at the protocol is not only a good idea but also necessary for efficient remote control.

Few months ago I purchased a used ICOM IC-706MKIIG in good condition and for a quite reasonable price. The primary reason for this acquisition was that l am spending 2.5 hours every day driving a car between my home and my work place and I wanted a mobile radio setup for shortwaves. Because of the detachable front panel the IC-706 is extremely suited for this purpose.

After completing the UI board I really wanted to see it work and test it one way or other without the RF board.

Last night I mounted the LEDs, the electrolytic capacitors and the LCD panel. I am using the HY28B which is why the display doesn’t align with the push buttons.

I forgot to post this update but I did make some progress since the last report in June. Finished mounting all connectors, buttons and encoders, see photos below.

Last night I finished mounting all the small parts on the UI board and today the board got cleaned of extra flux (there was a lot).

All parts have now arrived and I am soooo ready to build my mcHF

Please note that the information in this article is out of date and needs updating. I will do my best to update it soon.
In a previous post I wrote about using the UT-100C DVB-T modulator on linux and I promised to follow up how to use the modulator with live video sources. In this post I am going to describe how to setup the modulator on a Raspiberry Pi equipped with a RaspiCam camera module, effectively turning the Pi into a live HDTV transmitter.

Building the UT-100 driver module on the Raspberry Pi can be done the same way as on the desktop. The only difference is that instead of “sudo apt-get install”-ing the kernel headers and sources we have to fetch them from the Raspberry Pi git repository and install them manually. Although my instructions are written with the UT-100C DVB-T modulator in mind, the procedure is applicable to other out of tree kernel modules as well.
