PPM with Asiar Pro - High pitched buzz

Post by StefanM »


I bought a Powerbox Micro for my little portable rig and power everything from the Powerbox Micro that is connected to a Jackery 500 powerstation (with a 12V DC "Cigarette plug adapter cable").

I experienced a small thing: My Asiair Pro is producing a quitly high pitched buzzing noise when connected to one of the 12V DC Outs of the Powerbox Micro. That isn't the case when powered thru an external 12V 3A PU.
Everything else is working fine.

Should I be worried? What may cause the Asiair to do this when connected to the Powerbox Micro? (btw: Nothing else was connected to the Asiair while doing the test)

Thank you!
