Excessive warning about have Inverted cmd.hdr

[KG6KZZ]

I was getting too many excessive warning messages indicating that the header is inverted when the radio channel is in idle states with no traffic in the air.

Perhaps, it is due to too much audio gain on idle RF channel. In stead of root causing the problem, I reduce the trigger level of Inverted Header warning only when the received header is exact opposite. This drastically reduced the number of warnings, but still able to inform the user when the actual header is inverted.
