Hi Wolfgang,
I have found the reason of this issue. Version 5.102 and higher implements an "under construction" code for a new analog S-meter function which will work under certain transceivers. I implemented the code for some transceivers (ICOM, Kenwood and new Yaesu models) but I couldn't test in Kenwood and Yaesu because I don't have any. Except ICOM and new Yaesu, every Kenwood transceiver has different values for s-meter and I need to write a different code for every model (which is nightmare really...). I did a mistake in the line to read the s-meter value for the TS-890S.
I have fixed this and I have enabled the S-Meter function in the VIEW menu. Please download and replace the executable file by this one:

Please let me know if now it's working well. Also test the S-Meter function. Keep in mind that S-meter reading is not accurated and may differ from your real S-Meter reading in your transceiver.
