[chirp_users] Chirp and the volume control
I'm curious, why does Chirp advise you on Baofengs "(volume may need to be set at 100%)"?

In 4+ years I have been programming these radios I have only turned the volume up enough to get them powered on. These radios are programmed digitally using serial communications. The programming cables that I have don't even have wires for the speaker audio or mic audio. The volume level should not make any difference.
That being said, someone insisted that it clearly made a repeatable difference for them. Volume low = unreliable cloning. Volume high = reliable cloning. Maybe something in the volume settings of these cheap radios affects the TTL levels of the serial communications. Setting the volume to high shouldn't hurt anything (the internal speaker is disconnected) so I reluctantly added "(volume may need to be set at 100%)".

Thanks Jim. I was just curious. BTW, thanks for all your hard work you have put into Chirp and the help you offer others.

I have noticed this intermittently on the lower end Kenwood LMR radios as well.

It might be the pots get dirty at the low end and cause a problem. Just a guess, and probably not a good one at that.

On my uv5rc unit the volume control does control the volume of the speaker/mic. Thus it would also control the amplitude of the radio to computer signal while reading the radio. I expect that the chip in the cable starts with an adc which would only give a high with adequate volume level. My cable and radio works at half volume but other combos could need full volume and higher is better.

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.

Mine would not program without the volume control turned up.

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.
