Hey, i'm from the uk and i'm at 113, curiously as soon as i plug in the charger it drops down to 88, do you think changing it back up would solve the issue of the transmitter being unusable when charging? I use my transmitter in my C3 at 107.3 with pretty decent reception, i occasionally get a bit of static, mainly when other pirate stations cross the frequence. I drive in the essex area and about the north m25 with my n900 sitting besides my steering wheel.
