I purchased a PiZero Hat that included updated instructions for setting up the audio with simpleusb. I have misplaced those instructions. Is that document available or can the new settings be given here? Unless I missed it, I could not find an update instruction in Files for this group.

Hi Mark,

I have uploaded the document to the File section of this group.

Hi Steve:

I noticed that the suggested settings in this file are listed in an image, which isn't particularly useful for those of us with screen readers. I can scrape it with OCR, but it isn't very accurate.

On all my HamVoIP systems, I like to turn the DSP value way down, usually from 999 to 200, then increase the Tx Channel A level to compensate for that. This results in far less clipped/squished TX audio from the SHARI.

I also turn the rxaudiodelay value up, usually between 6 and 8, so people don't hear my squelch tail when I unkey. I've noted that many SHARI users don't do this. It isn't necessary, but it's nice.

Just as an example, this is how that part of the PDF appears to my OCR scraping. It's pretty mangled.

Reacrse Burst: n
squelch value: 1
Volume Value: 6
PreEmphas15 Enabled: y
High Pass Enabled: y
Low Pass Enabled: y
I suggest pu use these values when you first program the SA818 in a kit you build or you reprc?gram
the SA818 in an assembled SHARI.
Since filtering and pre/de-emphasis is tumed on in the SA818, you need to turn them off in Allstar,
So you should use the following settings in your simpleusb-tune-menu if you use the alwv?e SA818
