Hi,

downloaded the firmware updater from lab599 and latest firmware. When running the firmware updater, it says it cannot find the device. Can't find a detailed procedure on their site for updating firmware on the lab599 tx-500. Thank-you mike WA0SPG

It's in the full manual - https://lab599.com/upload/Lab599-TX500-User-Manual-EN-v03-2021.pdf, page 24. Before updating you need to put tx-500 in firmware update mode:

While holding the third top function key, turn on the TX-500. The screen will display “The loader is waiting…”

Then update app will be able to find it.
