If yours comes with some film on the right hand side remember to remove it as stops the channel up and down from functioning correctly. Interesting and nice weight to the microphone and now ongoing tests to see how well this idea is going to work.
Think the mass shipment of these maybe comes via sea shortly. It’s my understanding that only a few arrived at the moment.
Below the new revised manual

Over 100 emails about the engineer mode. Suddenly so many bad radios and from people who really liked them before
More FM Hub = Export Mode
More Power A Little = Jumper Move 2-3
More SSB Audio = Export Mode
Don’t need service mode for these things

I wonder if this “Key” pin on the connector is for connecting a CW key. Maybe, in that case, the microphone could be equipped with a 3.5mm socket for external keys, like mods for the Radioddity QT80 do exist (see product page). Might even be possible with the original mike?

If the microphone keys in CW mode then socket mod will work
