[QUOTE="PhaseTech, post: 475323, member: 3149"] Possibly because in your area, 195 - 210 is a particularly quiet range. I always notice when in a bad emi area, the Auto Tune is usually a high number. 128 is just the mid-point on the scale, there has to be a value in there from factory, so why not start in the middle. The manual is correct in that if you get to a new spot, it would take forever to audition the noise level in each channel number. I think it is sometimes possible to find a quieter single channel, than what the Auto Tune selects, and you can find a sweet spot for a particular location, but this is usually worked out (calculated??) over repeated trips to the same area. If you keep a finds diary, well worth jotting down your Tune number whenever your machine was running sweet and particularly when you found something. [/QUOTE]
