I have found that one can put their callsign on the LCD display, but is there any way to get it to display the current frequency, mode, band etc? And what do the buttons do, besides the reset procedure?
When the 6500 and the 6700 were designed, the intent was for the OLED display to be used to provide diagnostic and status information in addition to allowing for positive user interaction to initiate boot time events, as it does now. Currently, there are other higher priority software projects to address than adding additional diagnostic and status information to the OLED display. At some point in the future, these types of features may rise to the priority level where additional functionality is added.
