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.

Thanks,

Before you update your image capture your current alsamixer settings
somewhere. Just run ./n7nix/bin/alsa-show.sh & make a copy of result.

First of all, thanks for all the time you are putting in.
See suggestion for PCM, LO Drive gain below.

Tried to take a scientific/stepwise approach with setting the DRAWS board
audio out today.

I went through the entire level and deviation check routine again today and
wound up with very similar settings to my previous attempts. I then tested
direwolf VHF-FM first and then after disabling AX25, fldigi and wsjt-x on
HF. Results "ain't purty", but at least everything is being consistent.

Software function status:

VHF - with direwolf/Xastir transmitting and receiving on the local packet
network does work .

Comment: I don't really have a an easy/better way to test than function on
APRS network locally. I have a sense that the audio may be high, but I won't
know until I have time to putter with Spectrum Lab. It will become my
"Deviation Meter" with an IC-7100 functioning as my "sensor".

Check this out by John Ackermann N8UR
Look for: "The No-Test-Equipment Packet Adjustment System"
https://www.febo.com/packet/layer-one/transmit.html

Do you have a handy talky?
use the measure_deviate script: n7nix/deviation/measure_deviate.sh
Pick a tone, bring-up alsamixer Set PCM to 0db & drop LO Drive until there is no
clipping ie. no distortion or just follow John Ackermann's suggestion.

UHF - have not tried anything yet. TBD

HF - With the alsamixer settings below (visually they produce the "lowest
splatter" per an IC-7300 panscope and using Spectrum Lab 2 with the IC-7300
internal audio subsystem via USB. Rig coax is grounded, RF gain at 20% with
20dB of attenuation:

1. Fldigi drives the IC-7000 up to full power (if set) but transmits a very
dirty sig at any power above 5%.

Comment: The sig can be copied by others, but the ALC bar is reading 60%.
Not making any friends in the PSK world. These are ALC symptoms. Reducing
either the PCM level or LO Driver Gain results in very much increased noise
and a feedback like whistle at a different freq. Increasing the two settings
results in more splatter and harmonics.

2. WSJT-x receives just fine but DRAWS produces only an extremely low
transmit audio level according to the IC-7000 and signal being received on
other transceivers. Only testing with FT8 no other JT modes tested. TBD:
wspr.

Comment: In transmit there is no Power Out deflection on the IC-7000 - even
if I adjust the PCM and IO Driver levels to the max, together or separate.
So the PCM/LO Driver Gain level settings that "work" in fldigi, don't work
in wsjt-x. I even went back to check that invoking wsjt-x did not somehow
tweak the alsamixer settings. they remained the same.

Key Question: Why is DRAWS overdriving in fldigi, and then not putting out
enough audio level to drive the IC-7000 to set power level in wjst-x FT8
mode with alsamixer settings remaining the same between apps?

I don't have an answer but your description is a good data point.

Here are my current alsamixer settings:

PCM L:[-21.50dB], R:[-21.50dB

ADC Level L:[-2.00dB], R:[-2.00dB]

LO Driver Gain L:[6.00dB], R:[6.00dB]

IN1 L:[10kOhm], R:[10kOhm]

IN2 L:[Off], R:[Off]

So PCM set that low is very suspicious. It means you are not using many
bits of the CODEC. I would play with returning PCM at least close to
zero & dropping LO Driver Gain down.

I am stuck until I can figure out how to coerce wsjt-x into transmitting at
set power with the same audio input levels to the rig as provided in fldigi.
At this point I don't even care if the overdrive issue isn't solved. I have
decided to put the FT-817 aside because other are working/reporting on it. I
am only testing with the Beta 5 provided software and the IC-7000 until I
get these critical pieces working reliably because that will be my main
radio for this DRAWS kit.

Now need to go pay attention to other stuff (like family and the local zoo
of 4-legged furries we keep here on the farm).

Yep. I understand.

Thanks for thinking this through with me.

Thanks for taking such a methodical approach.

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

Fixed typo for FT-891:
IN1_L & IN1_L -> IN1_L & IN1_R
IN2_L & IN2_L -> IN2_L & IN2_R

/Basil

I've been staring at the FT-891 & 817 Yaesu manuals and discovered the
following for those 2 radios: (Warning I do not own either of these
radios)

You need to match your Yaeseu radio configuration settings with the ALSA
settings used to config DRAWS.

FT-891
------

If your radio is set for DATA (PSK) operation use ALSA settings IN2_L &
IN2_R. Turn OFF IN1_L & IN1_R

If your radio is set for RTTY (FSK) operation use ALSA settings IN1_L &
IN1_R. TURN OFF IN2_L & IN2_R

See pages page 62-66 of manual FT-891_Advance_Manual_ENG_1806-F.pdf
Yaesu mDin6 pin 4 is labeled SHIFT, this is Discout on other radios.
Also see page 25 of manual FT-891_OM_ENG_EH065H201_1611A-BO-2.pdf

FT-817/818
----------
See page 41 FT-817ND_OM_ENG_E13771011.pdf

Different connections are used for 1200 & 9600 (AFOUT & DISCOUT)

ALSA settings
Use IN1_L IN1_R for 9600 baud (DISCOUT)
Use IN2_L IN2_R for 1200 baud or less (AFOUT)

Radio settings
Use Menu #40 (PKT RATE) to select DISCOUT or AFOUT
Also Menu #39 (PKT MIC) allows adjusting drive level.

Basil, I have an 817 that only get taken out of the closet to keep the
battery healthy. I bought it for my daughter, but she isn't ready to commit
to a home station.
I purchased a DRAWS to support the development and out hobby. I have no clue
as to what to do with it, but I know it takes money to develop. So there you
have my contribution. I eagerly await a turn key solution and image.
I would be willing to send you my Yaesu, if you think it would help further
this project. You just have to let me know.
This is not a trick.

quick update: got rid of imagemagick (xastir breaks and can't find it), used graphicmagick instead

Also, I still cannot get the gps to update in xastir. It works fine in YAAC and it shows the fix/time perfectly fine.

anyone get xastir to update with gps? i'm running 2.1.1

Ok, so I'm running xastir 2.1.1... and i'm having issues with the gps

I have the networked gps set up and when I run gpsmon it shows i have a valid fix, however when i go to view -> gps status in xastir it says either 'gps data older than 30 seconds' or 'sats/view:00 fix:invalid'

does anyone else get that?

if not what version are you running and what did you install to get it to run?

Art

Thanks. I distilled your alsa config to this:

PCM L:[0.00dB] R:[0.00dB]
ADC Level L:[-2.00dB] R:[-2.00dB]
LO Driver Gain L:[0.00dB] R:[0.00dB]
IN1 L:[10 kOhm] R:[Off]
IN2 L:[Off] R:[Off]

/Basil

Another issue came up for me, and this stems from a repository issue but I thought I'd add it here

So, when you install xastir from apt (apt-get install xastir), it pulls a fairly old version.... which I can't get the gps to work right in it (keeps saying the data is over 30 seconds old)

I've updated my install script to deal with this, however I am now having to install at least one library from source (imagemagick) and a few other things along with my initial install.

right now here is the library support file list you need for current versions of fldigi and its suite, plus xastir:

sudo apt-get install libfltk1.3-dev libjpeg9-dev libxft-dev libxinerama-dev libxcursor-dev libsndfile1-dev libsamplerate0-dev portaudio19-dev libusb-1.0-0-dev libpulse-dev libmotif-dev gpsman gpsd gpsd-clients python-gps pps-tools libgps-dev chrony -y

that will auto install all the libraries that should cover the current fldigi build, for imagemagick run the following:

sudo apt-get remove imagemagick -y
sudo apt-get build-dep imagemagick
cd ~
git clone https://github.com/imagemagick/imagemagick.git
cd ImageMagick
./configure
make
sudo make install
sudo ldconfig
identify -version

identify -version should kick out something like 7.0.something,

once done:

cd ~
git clone https://github.com/xastir/xastir
cd xastir
./bootstrap.sh
./configure
make
sudo make install

NOTE: when configuring any software from source always read through the summary at the end... double check that it finds everything then continue with the install, when in doubt double check the programs website and build instructions and make sure it compiled correctly

also, most ham radio software in the apt repository is severely out of date... compiling from source is recommended for fldigi and xastir. direwolf seems to be fine as.

My script for the DRAWS board is located at github.com/nouse4anick/DRAWS, its still a work in progress (I have to update the config files for fldigi and xastir, direwolf seems to work fine) however you can still use it and modify it to do quick installs when you have to update your image.

Tim,
Take a break but don't give up on it. Even with my frustration, I know the DRAWS is a huge step forward in portable digital ops for ham radio. I also know we will get there.

Bob, thanks to you I had my first psk31 qso today with FLDigi and the 891. The miniprosc cable worked like a charm. The mod for the NW Digital Radio cable did not work. 
I still had a very high ALC, but this is forward motion.

julian oh8stn

Hi Jack.
You described perfectly one of the FT891/ftt817 symptoms. I can not reduce levels low enough to get the ALC to zero. 
I was able to have a QSO with FLDigi today, but was told my signal was a couple of hundred hz wide. :(
Thanks for the support Jack. I love the potential for the DRAWS, and won't give up.
