Good afternoon, The following occurs here. I work with the yaesu FTdx101MP and when I work with commander and I set my filter in Commander to narrow it automatically goes to 450Hz Can I set the filter narow myself or is it always 450Hz?
+ Yaesu's CAT documentation for the NA (NARROW) command does not describe its actual function. I suspect that it controls the "IF NOTCH WIDTH" mentioned on page 99 of the Operator's manual, but that's a guess. If all else fails, contact Yaesu support.
