Why does my Flex 3000 make cracking noises from inside when it gets warm?
Harry

My Flex 3K makes cracking noises inside the blue box when the PA gets warm. I don't really bother with that noise since I most of the time operate with headphones on. But when something expands/ contracts all the time, I am afraid it will eventually break. Any idea how I could identify the cracking source or should I not worry at all? 73 Harry, 7Z1HL

Harry, We need to look into this hardware issue in more depth. I have converted this Question topic to a Problem post and transferred it to the HelpDesk. If you are experiencing issues of this nature, please submit a HelpDesk support ticket (using the Zendesk link on the front page of the community in the right side bar)0

Mine did this popping for about 6 months and finally settled down. It is some kind of thermal expansion.0

Hi Tim, I loosened all screws of the PA board and moderately tightened them again. Now the radio is lovely quiet again as when it was new. I guess the screws holding the board to the chassis were too strongly tightened after repair. Case closed and one more happy ham with a Flex 73 Harry, 7Z1HL1
