hHere is a residual remnants?of the Resident Ghost o]f the Original Ghost On the Air in all units of the SBIITX and ZBITX..... The remnants of the ghost does some strange things, normally resolved by replacing the SD Card with another copy of the same -just ensure that you?have multiple copies of the sd cARD AVAILABLE. If you change the boot order and get it to boot from the USB Drive, it gives you some additional options!!!!!!...... PUT THE GHOST ON THE AIR TO REST!!!!!!

Have you made any progress?

Previously radio showed power and 1.0 swr on 15, 20, and 40 meters with similar readings on the off board meter.
As of this morning swr on the radio and the off board meter show high SFR 2 to 3:1.
Removed the radio from the antenna line and replaced it with an antenna analyzer, it shows a perfect 1:1.?
Another radio shows 1:1 on the radio and the off board meter.
?
Previously, maybe a month ago I had the same problem, spent time chasing down the antenna to no avail. Then one day all was well with no intervention at or in the radio.
?
All bands that were workable for the antenna show the same behavior today.
?
Trouble shooting help welcomed.
