Hi to all.
I'm electronic technician and i start to repair some equipments for gliders and planes.So i have a problem with a Becker AR3201. The problem is when you press the PTT to talk or you receive a signal you hear at the headset or at the speakers a noise like the noise from alternator. I try to install a power line filter but without any success. I try with the engine not running (only with the battery) and the problem is still presents.
Any idea what happen ???
Thanks for any help.
