Hi all,
I opened up the T16 to get rid of the play on the scroll wheel. Since then the radio makes a static sound ‘tac’ on power up, like before the screen powers up. Shouldn’t be anything related so I am perplexed. Maybe some electronic wiz has an idea?

This is a known issue to some T16 and reported to Jumper. Last I saw an update from them, they said they would address the issue in future firmware updates.
