Batboard

When I go to read from the Johnson, it loads for 1 second then says “invalid file read/opened. Operation aborted.” The radio then shuts down and restarts. The programming will read the version and options though. Using PCConfig 1.28.0.8.
Radio:
File Format Version: 5.8
DSP Software Version: 1.2.3
Controller Version: 1.18.15

Solution found! The last owner used 1.30.07. As the pcconfigs are not backwards compatible, it wouldn’t let me use the 1.28.x version.
