Found this, the mixer is making more sense now: http://www.ti.com/ds_dgm/images/fbd_slos602c.gif
I spent a while staring at the draws schematic trying to figure it out when I finally realized the DIN6 sockets weren’t diagrams, and that pins 4 and 5 are supposed to be on opposite sides.

If that's not how it works, then how does it work? That’s exactly how it works. The TLV320AIC3204 has three inputs that can be connected to the ADC. Each input also has an inline resistor that you can select from the mixer. We suggest that you use 10k, because that’s been shown to work in all the situations we’ve tried, but if you need to do some advanced configuration you can use the 20k and 40k values. Please also note that it is a valid configuration for the codec to hook both input 1 and 2 to the ADC at the same time. The signals will merely get mixed. So, if that’s not something you desire, remember to turn off 1 when 2 is in use and vice-versa. Also read the entire mixer description. There are indeed switches for things like “IN1L to Right Mixer” where you can cross things up. The “ADC Level” analog control determines the input gain for these. Left and right are separately controllable. I’d love to be able to pare down these options to be more specific to udrc/draws, but the alsa code doesn’t really allow you to do that very easily. On the output side, it’s quite a bit simpler. There’s one right and one left output off of the DAC. They are hooked to one of two amplifiers, LO and HP. LO is line out, and HP is headphones. UDRC/Draws only brings out the LO amplifier to pins. There’s an “LO DAC” control that should always be on unless you never intend on transmitting. This hooks the output of the DAC to the LO amplifier. There are then two output controls, one for each of the left and right pin. These are brought out to the output pin on the DIN6. The trickiness here is that there are two level controls for the output. The first is the PCM control. This controls output from the DAC itself. The thing to note about this control is that it’s a digital control, which means it’s really just multiplying input values to the DAC by a scaling factor. That means that the lower you set it, the less effective bits of the DAC you’re using. This can cause more quantization noise in your output. The other control is the “LO Drive” control. This controls the gain of the LO amplifier. Because of the lack of quantization issues, you would prefer to use this one for the bulk of your setting if possible. With regards to the “LO Drive” and “PCM” controls, my experience has shown that 0dB on both controls is pretty close to clipping the outputs, so use caution when adjusting them above 0dB. If you need more output than the defaults can provide, there’s a secret device tree overlay called udrc-boost-output that’s in our repository that you can use to change the power source of the LO amplifier. How to use such is an exercise for the reader since it’s rarely needed. And what is IN3? A Unused. -- Brian N0KZ -- Annaliese McDermond (NH6Z) Xenotropic Systems mcdermj@xenotropic.com

I am looking for some basic guidance on getting fldigi configured for VHF and UHF. I have been successful with the DRAWS Beta 5 image and running Direwolf/YAAC and now that I know the "core image" checks out and works. I rebooted the PI/DRAWS combo and shut down Direwolf and ax25 with this command sequence: cd bin, sudo su, ./ax25-disable. I then selected fldigi from the drop down menu on the home screen of beta 5 image. When the configuration helper for fldigi comes to selecting the sound card I am left with one option and that is to select "pulseaudio" and it responds wit no pulseaudio server. It doesn't give me an option to choose udrc 0 or 1. What do I do from here to get an audio source selected ??? Thanks Joe K3JV

Jack Spitznagel
Joe, - Check to make absolutely sure that Direwolf is not running after your reboot.
- If it is not running, you should see PortAudio as a selectable option. Check the box.
- Now Select udrc: - (hw:0,0) for both capture and playback.
- You can also check “Device supports fell duplex” (it is in mine by default and I just left it that way)
Hope that helped. KD4IZ Jack Spitznagel FM19oo

Thanks, Indeed ax25 was not shut down I ran ./ax25-stop after ./ax25-disable and that did the trick. In the fldigi set up port audio lite up and I was able to select hw udrc 0.0 for capture and play back. I will let you know how I make out getting audio levels right for my TM-V71.

Next issue is with getting the radio to transmit. First off, I
have used Fldigi with the TM-V71 many times on vhf uhf with
success using a signalink and a sound cards with simple
interfaces. I noticed right of the bat that the squelch on my
radio does not stop the waterfall with the DRAWS interface...what
is that about? Using the alsa mixer control no value of ADC
changes the waterfall appearance, it doesn't dim or get brighter
with open squelch. Squelching off the signal of the radio does not
stop the water fall ??? I have never seen that before. Lastly I
cant key the radio and no value of Lo Drive Gain or PCM makes any
difference.
Do you have any suggestions ???

Hi Joe, You have a radio I do not know anything about. I’m only about a week ahead of you in learning how to make DRAWS sing. I just happened to have been working with fldigi and my IC-7000 and the questions you asked were central to making fldigi work with the DRAWS hat audio device and that rig. How did you configure fldigi to key your radio? Since you are no longer using a SignaLink, you can’t rely on the SL VOX keying circuit. If you want to use VOX for PTT, the radio has to have a VOX function and it has to be set up and adjusted. Only other approach I can think of is to make sure your radio can be controlled and/or keyed by flrig’s CAT control and set it up. Then set fldigi to control and key the radio using flrig. That seemed to work for me with my IC-7000 and Yaesu FT-817. Sorry I can’t be more helpful. KD4IZ Jack Spitznagel FM19oo

I wanted to share the good news of having success with the Beta6
image of draws with Direwolf , YAAC and a leap today with fldigi
running on a Kenwood TM-V71 dual bander.
I downloaded the beta 6 image today and ran through Basil's
"Verify_Config.md". I found a notation symbol that gave me
trouble until I changed it.
Under "check ALSA settings for deviation " instructions go as
follows:
cd ~/n7nix/debug
~/alsa-show.sh
I removing the tilde and the ~/ for the line alsa-show.sh after
trying the command as noted several times and then it ran fine.
At first I couldn't get fldigi to allow me to select udrc under
the sound card configuration. It just wasn't there. During the
Verify_Config.md the instructions required two changes in the
/boot/config.txt to test analog audio un comment, remove the #
from dtparam=audio=on and /boot/config.txt hdmi_drive=2 when your
done with the Verify_Config.md make sure you go back to
/boot/config.txt and comment out, put the # at the beginning of
the lines #dtparam=audio=on and #hdmi_drive=2.Reboot and run:
sudo su
cd ~/bin
./ax25-stop
also run :
sudo su
cd ~/bin
./ax25=disable
Now select fldigi from the "internet menu" on the home screen and
you should be able to go to the "configure" menu of fldigi then
sound card and select "port audio" in the drop down menu you
should see the selection for "udrc". If you dont it either means
you have not shut down ax25 or you didn't comment out
dtparam=audio=on or hdmi_drive=2
Also from the home screen of pi go to preferences and bring up
"Audio Device Settings" and setup PCM, ADC Level and LO Driver
Gain.
I found that setting the audio out (Transmit) levels where easy
to adjust to -20db using the alsa mixer controls of PCM and Lo
Driver Gain. I use a free audio spectrum analyzer called
"Spectrum Lab ver 2.93" for setting the audio drive level on
fldigi for FM vhf and uhf. For HF the best thing is to adjust the
xmit drive level so you have NO ALC showing for ssb transmit. The
signals sound clean on second TM V71 I have. Also the receive gain
was easy to adjust to keep the audio within range of the green
indicator diamond on fldigi.
I had not experienced the issues that people were having with
FT817 at Ft 891 ?? but I had not tried fldigi with the beta 5
version of the image. Beta 6 seems to work just fine with the
Kenwood TM V71.

I found that setting the audio out (Transmit) levels where easy
to adjust to -20db using the alsa mixer controls of PCM and Lo
Driver Gain. I use a free audio spectrum analyzer called
"Spectrum Lab ver 2.93" for setting the audio drive level on
fldigi for FM vhf and uhf. For HF the best thing is to adjust the
xmit drive level so you have NO ALC showing for ssb transmit. The
signals sound clean on second TM V71 I have. Also the receive gain
was easy to adjust to keep the audio within range of the green
indicator diamond on fldigi.
I had not experienced the issues that people were having with
FT817 at Ft 891 ?? but I had not tried fldigi with the beta 5
version of the image. Beta 6 seems to work just fine with the
Kenwood TM V71.

Hi Joe,
You have a radio I do not know
anything about. I’m only about a week ahead of you in
learning how to make DRAWS sing. I just happened to have
been working with fldigi and my IC-7000 and the
questions you asked were central to making fldigi work
with the DRAWS hat audio device and that rig.
How did you configure fldigi to key
your radio? Since you are no longer using a SignaLink,
you can’t rely on the SL VOX keying circuit. If you
want to use VOX for PTT, the radio has to have a VOX
function and it has to be set up and adjusted.
Only other approach I can think of is
to make sure your radio can be controlled and/or keyed
by flrig’s CAT control and set it up. Then set fldigi to
control and key the radio using flrig. That seemed to
work for me with my IC-7000 and Yaesu FT-817.
Sorry I can’t be more helpful.

Next issue is with getting the radio to transmit. First
off, I have used Fldigi with the TM-V71 many times on
vhf uhf with success using a signalink and a sound cards
with simple interfaces. I noticed right of the bat that
the squelch on my radio does not stop the waterfall with
the DRAWS interface...what is that about? Using the alsa
mixer control no value of ADC changes the waterfall
appearance, it doesn't dim or get brighter with open
squelch. Squelching off the signal of the radio does not
stop the water fall ??? I have never seen that before.
Lastly I cant key the radio and no value of Lo Drive
Gain or PCM makes any difference.
Do you have any suggestions ???

Joe,
- Check to make absolutely
sure that Direwolf is not running after your reboot.
- If it is not running, you
should see PortAudio as a selectable option. Check
the box.
- Now Select udrc: - (hw:0,0)
for both capture and playback.
- You can also check “Device
supports fell duplex” (it is in mine by default and
I just left it that way)
Hope that helped.

Issues #setup #fldigi #draws
I am looking for some basic
guidance on getting fldigi configured for VHF and UHF.
I have been successful with the DRAWS Beta 5 image and
running Direwolf/YAAC and now that I know the "core
image" checks out and works. I rebooted the PI/DRAWS
combo and shut down Direwolf and ax25 with this
command sequence: cd bin, sudo su, ./ax25-disable.
I then selected fldigi from the drop down menu on the
home screen of beta 5 image. When the configuration
helper for fldigi comes to selecting the sound card I
am left with one option and that is to select
"pulseaudio" and it responds wit no pulseaudio server.
It doesn't give me an option to choose udrc 0 or 1.
What do I do from here to get an audio source selected
???
Thanks

Merry Christmas Julian
All of the adjustment I made to the receive signal was through
the ADC Level of the alsa mixer. FLDIGI has a go no go "diamond
shaped" icon on the bottom tool bar of the main screen. It
lights up "black" for low receive audio, "Green" for ok and "Red"
for over driven receive. The ADC Level adjustment got the green
diamond to light with plenty of room to spare.

Excellent write up Joe.
Did you adjust any other setting than adjusting
ADC level in alsamixer for receive level?
Outstanding post.
Thanks for sharing
