Shack Status (2026/01/26)
Shack's appearance.
On the right are the shortwave YAESU FTDX3000 and FT-891
On the left is the ICOM IC-820H for satellites and a Kenpro rotator
To the right of the radio are a Lenovo ThinkPad X390 and a ThinkPad X1 Carbon.
For digital communications and software development

These are the ICOM IC-820H for satellite communications, the Kenpro Rotator KR-400, and the elevation rotator KR-500.

The last connector arrived on January 25th, but communication has not yet been established.

For about 10 days I barely played radio and was busy programming the repeater controller.
Programming with Arduino IDE for Mega2560 MPU
Finally, the framework has been debugged and is working smoothly.
Settings can be made using the PC setting software or the TFT LCD touch panel.

Once you receive the RTC DS3231 and DFPlayer Mini MP3 Player, you can create a voice ID function and you're done!

It was a great deal and we had plenty of fun for 10 days.
