I just bought a new programmable Sansamp BDDI and I noticed that my 2nd and 3rd channels are noisier than the 1st channel. The first channel is dead quiet but channel 2 has a mild buzz and channel 3 has a fierce buzz. Even when all settings are the same, it gets progressively louder. I read reviews that said it's not silent when changing channels but I thought it meant that there was a minor pop when changing channels, not having two that are not usable at all. Anyone else have this problem? The battery used in the BDDI was brand new.
