If you want to bother, turn off polling. Turn on data logging on the first tab of the Misc Ham Setup screen. Close that form, operate the kenwood for a minute.  Turn off data logging. Send me the data log file.  It will be in the TMP folder inside where LOGic is installed (C:\program files (x86)\LOGic\tmp unless you installed it elsewhere).
Tnx & 73,
