On which channels do you see a difference? OK,I should fix description of band. Mayer> Do you have a clear picture in windows? Yes. Why clear, Japanese VHF band not use (about) 108-170Mhz. Below is *ABOUT* Frequency of Japanese TV band; VHF-LOW : 90-108 VHF-HIGH: 175-225 So, in Japan, this parameter is effective a coincidence :-( But, in Japan, configuration setting of tuner is more important than frequency. On setting of TUNER 2 or 17 ( a0,30,90) , VHF is not receive, and UHF is very low gain. On this setting ( at path: 40), gain is okay...but configuration of UHF is 04 more stable. Regards, Ohta.
