Fred: do you mean change to the ICAO ID, or use a device ID that is different from the chip ID? Yes to the first (see the user guide), not quite for the second. The transmitted device ID (as hex) is "8" followed by the last 5 hex digits of the chip ID. If that's not what is registered with OGN, change the registration. If that's not possible, there is a way to "override" it, see the "under the hood" document.
