I put mine on a scope and watched the data stream. The volume control had no effect on the data. If it works for you and you believe it. I can see why Jim put it in Chirp.

Mine would not program without the volume control turned up.

On my uv5rc unit the volume control does control the volume of the speaker/mic.
As it should. The volume control controls the level of audio to the internal speaker and to a external speaker properly connect to the audio out lines.
Thus it would also control the amplitude of the radio to computer signal while reading the radio.
Incorrect. As I mentioned earlier, the radio communicates with the computer via a TTL level serial communication (+3.3 volts/0 volts). There is no speaker out or mic in audio involved. There aren't even any wires connected to the audio out or mic in because they are not needed or used for serial communications.
It is not AFSK (audio frequency shift keying) like over-the-air digital communications. That would be an added complexity that isn't required.
