Hi, I don't know if this is a Hamlib problem or a WSJT-X problem. I run a TS590S (Windows 10) and as you are aware I wrote my own logging/rig control software. When testing version 2.5.2 I noticed extraneous beeps from the TS590S whenWSJT-X switches from RX to TX. Using my software, I was able to determine that WSJT-X is sending extraneous Split commands ("FT1;" and "FT0") as it switches from RX to TX. The settings in WSJT-X is set to use CAT for PTT and SPLIT=RIG.There should be no reason to send these extraneous commands once WSJT-X starts and sets the TS590S into SPLIT. If this process is a regression in the new version, then please disregard thefollowing paragraph If the process was used so as to ascertain/set which VFO is used for RX and/and TX, it would have been much more efficient to use the "FR"/"FT" commands in conjunction with the "FA"/"FB" commands as it would be a lot less wear and tear on the relay in the rig. 73, Sam W2JDB
