Thanks

No Trimpot. slowly increased to 150. still not great. decided to try a 220 just to see. There was visible noise in some colors, and almost no improvement in jailbars. Truthfully the jump from 75 to 150 is not that noticeable either, but I guess I'll have to live with it. Is there always going to be bars in sms, or should I try looking for another model/chip?
