Many thanks to SWLing Post contributor, Jaap de Goede, who shares the following note:

Thanks for posting the hidden feature table to the Tecscun PL-330.

I see more and more videos of the PL-330 popping up on YouTube. I’m wondering what firmware they run. It’s easy to identify the firmware version.

Press and hold the VM/VF button when the radio is off. Release the button when all icons are displayed. Next, the display will briefly show the firmware version in the upper right corner. As you can see in the picture (above), mine has version 3302.

Thanks so much for the tip, Jaap! I am curious, too, if Tecsun is updating the firmware version with each release/update of the PL-330. With the PL-880, there were a number of iterations all carrying the same version number (8820, if memory serves).

It would be great for comparison purposes to check the firmware number.
