Cant turn off direwolf and ax25 #configuration #management #draws #direwolf #ax25

Bob Orrett <boborrett@...>
 

I am a newbie to RPi and linux. 
I have the beta6 installed and running. I cannot seem to be able to stop direwolf and ax25 so that ft8 and js8call will get access to the draws sound card.
I entered

cd 
cd bin
sudo su 
./ax25-stop 

The pi returns the command prompt but not anything like "ax25 has stopped".
I see the correct sound card input and output codec in the settings for these programs (ft8 and js8call) but no audio from the ft817 radio. I had this working before. What am I missing?

Bob Orrett <boborrett@...>
 

Great news. It seems that having all six pins connected makes the 817 unhappy. Basil said they know the problem now and will look for a solution. 
And having told you how successful I was, now I cannot seem to be able to turn Direwolf and ax25 off so that ft8 and js8call can have access to the sound card on the draws. I did it before and now it doesnt work. 
Do you use Basil's script?

cd 
cd bin 
sudo su 
./ax25-stop 

If you do, do you get a response from the pi. Like "ax25 has stopped". I get no response.

I am very pleased to have helped in some small way because you have helped me a great deal in the construction of my portable station. Just wish I could afford that 120w solar panel.

fldigi allows you to key the radio using the gpio pin interface (12) to mini din-6 (left)

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 ???

Edited

Basil, 

Thank you for the update on the 891. 

I only operate HF portable, so I connected the dummy load and corrected to:
 " If your radio is set for DATA (PSK) operation use ALSA settings IN2_L &
IN2_R. Turn OFF IN1_L & IN1_R "

There was an immediate improvement seen on the waterfall for fldigi.

Hopefully I'll be able to test in the field tomorrow.

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.

A couple of thoughts on #applications #beta #image #draws #support

 
Edited

I would just like to take few minutes to thank everyone for their testing and feedback on the images that we have for the DRAWS™ HAT.
 
We have key people at NW Digital Radio all looking at the feedback and trying to characterize how to provide quicker success for those trying various modes.  This includes Bryan, Basil, Anna, and myself.
 
I feel it is important to remember that we don't have every radio in the market, so our focus is on the proper settings for 'classes' of radio and applications.

We have several hundred UDRC/UDRC-II boards in the field.  The DRAWS™ sound chip and driver is the same as the UDRC/UDRC-II and we have users of those boards who have been successful with a variety of radios and applications. We are collecting feedback and will put it back out in a more organized fashion as we are able.
 
The beta image is put together as a starting point for operation of your DRAWS™ HAT.  It includes programs that are popular in the community and have worked with the UDRC/UDRC-II/DRAWS™ sound subsystem.  Interfacing the HAT to a given radio starts with a 'standard' DIN-6 interface as found in the packet radio world.  However, there are settings both for the HAT and the radio, as well as proper wiring that must be considered and optimized at the station level.  For example Yaesu mutes the speaker if the SQL line from the HAT is at a given level.  Also, there are two different pins to receive audio from the radio into the HAT, and depending on the radio and mode they may need to be selected, and have levels set, differently.  Also, some radios have internal settings for incoming levels from the HAT to the radio (e.g. FT-817 PKT MIC level), that must be matched to the output of the HAT.

We, at NW Digital Radio, are grateful for offers of documentation assistance, offers to loan equipment, and sharing of discoveries. We will incorporate such findings into documentation for users of the DRAWS™ system. We are hopeful that this community will be able to become a great resource for one another via our open communication and transparency in responding to support requests.
 
Just a few reminders:
  • All of the applications are written by people outside of NW Digital Radio and even though we include them on the beta image, as a starting point, the ultimate authority on the applications lies with the authors of those applications and their user communities.  We are here to help them optimize the programs to take full advantage of the DRAWS™ system and on occasion we have facilitated hardware and code to that end.  With your involvement and encouragement these applications will improve over time.
  • We are working on tools to make configuration and monitoring of the DRAWS™ simpler and more accessible, for example Basil's scripts, Anna's driver/hardware support, Bryan's schematics and hardware notes, and John's efforts on Wiki's and coming web based tools.  Some of us have full-time, demanding jobs in addition to the work we do at NW Digital Radio, but we try to be as responsive as we can.
Enjoy your holiday celebrations and know that we are working on DRAWS™ even as we celebrate outs.

73 from the great Pacific Northwest.

Re: Status: IC-7000 Audio Levels for V/UHF and HF modes #draws #ic7000 #hfmodes

Basil Gunn
 

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.

Joe,

 

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

 

Hope that helped.

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

Re: Status: IC-7000 Audio Levels for V/UHF and HF modes #draws #ic7000 #hfmodes

Jack Spitznagel
 

Basil and All,

 

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".

 

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?

 

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]

 

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).

 

Thanks for thinking this through with me…

Re: amixer questions Re: Set Up 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.

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

There is a wiki, it needs more content. If anyone wants to offer up some content, contact me.

Would love to have a sked with you, perhaps during winter field day!? Yeah, regarding the DRAWS, I know my post was a little harsh, but I find leaving out the diplomacy puts everybody on the same page. It also gives confidence to others to come out and say they're having a problem as well. So, based on the comments on the two videos and the blog, I had hoped on getting the "getting started" video up after xmas. Lots of operators are counting on it for the HF digital side. I'm kind of feeling like I let them down.

Let's see what the NWDR team says about a wiki. I think it's critical, and worth it, even if it delays the end result. I'm also willing to contribute to it.

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?
