Fault symptoms: icom ic705 wifi connection to ft8 is normal, but when JTDX frequency is opened, it repeatedly jumps erratically, and CAT always fails.
Root cause: The current JTDX has an outdated version of Hamlib, which has poor timing tolerance for the 【IC-705 + RS-BA1 virtual serial port + WiFi CI-V】 configuration. This results in out-of-order messages being misinterpreted as a trigger to send the VFO switch command.
Solution: Manually replace the Hamlib library within JTDX with a new version of libhamlib-4.dll from WSJT-X, which is known to work correctly, and place it in the JTDX directory.
