Friends,
I would like to point out a rather nice chat program for KST by Nick US8AR. In addition to chat, the program also includes a DX Cluster client and has a few interesting functions, as a QRG/QTF indication after clicking on the mark and displaying the hama image, if he has it on the QRZCQ server. The program is honored including a detailed manual. The latest version is available for download at https://sourceforge.net/projects/kstchat/. Installation consists only of unpacking the ZIP into a suitable directory and setting the startup icon on the desktop, so you can use e.g. even from USB memory.
The program looks like this: https://prnt.sc/EsWglQGmh7Ta
