[EX Q]: I bought 2 of these radios and at 1st i was happy with them but after a few weeks the sound became distorted (crackling etc) when playing songs or using in stereo mode on FM. You have to turn both radio's off and back on, then they resume normal. Tried upgrading firmware without any luck, tried multiple frequencies still not acceptable. Now one radio doesnt detect FM radio stations at all, cannot scan for weak signals. A poor purchase!
