This page purpose in give info about Yupiteru MVT-9000 series

I share my experience with those, all questions are wellcome.

Later on when i have time to do it, i will write my experience's with MVT-7300...

Is start, bit older info:

Yupiteru have made shielding even better After serial number 708xxxxx (cause CE certification)

    MVT-9000Mk2 vs. MVT-9000

    Just examined that, still basically same as MVT-9000 but one additional circuit board added and CPU  Board is slightly modified.
    CPU type and basic design is same as old one.
    Light changes on IF board and RF board is same as series 81xxxxxx 
    So no change's in front end. That "known" problem with that 10.8MHz is still bothering that unit!, Unfortunately!. 
    Modification is available for that unit!.
    That Mod basically give same additional features as modifications M2.4 and M3.4
    With mod MK2 model, is BEST scanner what i've own!!!  ;-) 
    But that's my opinion.....

    Only real difference in IF board is 455 kHz filter what was MURATA before is now change to TOKO made filter..... that cause little changes in AM/FM modes.
    Actually it have effect stop band attenuation.... less inference!.

    Also bandscope filters are different type than before but still MURATA's filters.
