Audio processing and ALC in the FT-897D. I recently bought an FT-897D, and after a period of operation noticed. problems with what I perceived to be a low average level of output power and. reports of muffled audio. This is the story of my investigation to improve the. audio quality and increase the average level of transmitted power.
Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel. For example, English suffix-s is pronounced [s] when it follows a voiceless phoneme (cats), and [z] when it follows a voiced phoneme (dogs).
The words differ by the pronunciation of the s. In one form (the verb) it is voiced like zzz, and in the other (the noun) it is voiceless like sss. This sort of heteronym is not confined to noun-and-verb pairs. Here is a list of heteronyms in which one form is an adjective.
