[Yaesu] Roofing Filter problems!

[Alfredo Velez WP3C]

Ok, Andreas thanks for your help!

     The Mark V in the menu 9-1 number 11 I do not have noise, in the number
12 one db.
     The MP in the menu 9-1 number 9 I do not have noise in the number 10
one db.

It is normal that the Mark V is in the 11 and the MP 9? 73'
