Hello to everyone...sorry for my bad english...the story begins: It was a nice (for me!) rainy day, actually a storm,and i decided to record some thunders....but i was "out of battery" and i had to use the charger... so when a thunder stroke nearby a static noise(click) came from my headphones and the md stopped...it wasn't an AC overload(i am sure of this) just very electric atmposphere(static everywhere)...since then every time i use the charger i hear a really strong 'humm' noise but only in record mode(not at playback)...so to avoid the hamm i record only in battery ,but i also noticed that when i am touching the keys from the md (not the remote) static(clicks) and humm noise occure...also when i'm holding the md near the center... anyone electronic engineer here in the forum?i don't understand why the problem is only in record mode... thanks!
