Well I think I have the answer to my question. The backlight on my controller times out after 15 minutes of no activity on the user interface and no changes in TS-590 data. I was alerted to an anomaly when the back light unexpectedly turned on. The data appears to show that WSJT-X made 2 frequency changes, presumably with the intention of testing the rig interface:
2019-07-17 16:54:17 104:19:42.598 backlight off 2019-07-17 17:05:11 104:30:31.127 New IF - IF00018100055 004100005020010000; 2019-07-17 17:05:11 104:30:31.131 backlight on 2019-07-17 17:05:11 104:30:31.138 New FA - FA00018100055; 2019-07-17 17:05:11 104:30:31.141 New RX freq=18100055 2019-07-17 17:05:11 104:30:31.142 split offset = 945 2019-07-17 17:05:11 104:30:31.447 New IF - IF00018100000 004100005020010000; 2019-07-17 17:05:11 104:30:31.457 New FA - FA00018100000; 2019-07-17 17:05:11 104:30:31.459 New RX freq=18100000 2019-07-17 17:05:11 104:30:31.460 split offset = 1000 I would guess that this unnecessary test sometimes fails. I am competent to monitor my rig's frequencies and take full responsibility if they are not what I intended. Please give me the option to inhibit this check. 73, Andy, k3wyc
