Finally after many frustrating days, wsjtx and js8call are working with the draws hat. It was my fault and probably a rookie mistake but I will explain in case others are making the same mistake. It is in Basil's script. I read the script each time that I loaded a new image but I misinterpreted how to use it. There is a line that says, "if you want direwolf functionality, do this". Well , I didnt want direwolf so I didn't do the script below. A mistake! When I finally decided to run that script everything worked. I was always wondering why I was never asked for a password (nwcompass). But even then it took many tries before i finally noticed that between "app" and "config" there is an underscore "_" not a dash"-". I have never seen and underscore in a command before and the print is very small. I realize now that i should get my email with the raspberry pi so that i can cut and paste instead of read and type. Linux doesn't help you when you make a typing error. Just says that the command does not exist. That make me think there is something wrong with the program, not my typing. I am a retired teacher and one thing i learned is that giving foolproof instructions is very difficult. There are often assumptions made by the reader and the writer that can result is complete misunderstandings. Adding the reason for a given command is a big help. Don't worry about insulting the reader, give hints and examples. Explain what the response to a given command should be. Well, i feels good to be over this hurdle, on to the next. Bob ve3obo.

Stand corrected.Still a lot to learn (and relearn) since I last looked at this about 25 years ago.

Jack: AX.25 isn’t needed for Net-44... that’s a TCP/IP function.

Art,
My experience as well, except when one might want to setup tunnel connection as part of the ampr.net (“44.” Net). I plan to be doing that with some DRAWS functions. I thought that was a big deal out there in the PacNW.

That is correct. Direwolf can run independently of the AX.25 stack. And programs that can talk directly using agwpe or kiss over the network work just fine (e.g. YAAC, Xastir). Basil has done a lot of work to have a stable, reproducible AX.25 stack available for a variety of programs that need it, including an RMS, BBS, and various other applications (commonly used in EMCOMM). While running the AX.25 application stack, these (mostly APRS) applications can also run through the same direwolf instance, using the same radios, over agwpe or networked KISS. Direwolf by itself is also a capable digipeater and igate, though we tend to use it more often as a modem and let other programs handle the higher level protocols.

Basil, John
I setup Beta 6 today. The install was painless, it may be my growing comfort with the setup, but it ran smoothly. Testing was where thing fell apart. Unfortunately I still struggling to get the both the direwolf and fldigi drives level adjusted with the IC-7000. It appears that the poster who suggested a 100k ohm (variable) resistor in the audio line from the DRAWS to the transceiver may be correct. I will upload a text file of my observations while running the "Ackerman" no-test-equipment deviation method" style adjustments and using the "measure_deviate.sh" script if desired... but this should cover almost everything: In short: 1. Audio drive was too high for the IC-7000 as it was defaulted by AX25/direwolf setup. 2. Used the "setalsa-udrc-alinco.sh" script to set the audio levels to a level that "worked" NOTE: I tried all of the scripts you included. The Alinco" levels produced a signal my HT and APRS gateway could decode - it sounded hot though. 3. While "measure_deviate.sh" was activated, reduced PCM all the way, then increased it until I heard no increase in volume of the received signal. That point occurred at about -6.00 dB - but ALC on the rig was still very high. LO Driver Gain level was already at -6.00 dB. 4. Re-enabled the AX.25/direwolf stuff and observed that these levels still resulted in decodable APRS [packets). 5. Killed AX.25, went to fldigi and SSB to see how the audio output was driving the 7000. ALC was still very high. 6. Increasing PCM increases distortion sound and visual splatter on Spectrum Lab. 7. Backing PCM to -21.00dB saw the ALC start to drop - but would not drop below 50% point. 8. Once PCM drops below about -25.00dB, the ALC starts to pump and the signal gets dirty sounding with a feedback-like harmonic beginning to be heard with loud hiss and crackling noises. These "best outcome" alsamixer levels are still not optimal by any descriptions I have read. I don't challenge that. PCM L:[-21.00dB], R:[-21.00dB] ADC Level L:[-5.00dB], R:[-5.00dB] LO Driver Gain L:[-6.00dB], R:[-6.00dB] IN1 L:[10kOhm], R:[10kOhm] IN1 L:[Off], R:[Off] Conclusion - AFAICT, clean audio IS being produced at higher PCM and LO Driver Gain levels - but the signal is at too high a level for the IC-7000. NOTE: I seem to remember I had to use the dropping resistor setting in the SignaLink with this radio. So that leads me to the conclusion that a variable resistor/ resistance network will be needed to get clean audio at a level that the IC-7000 (and apparently some other radios) seems to like. Next time I have the unit apart, I will try to find a good test point to measure the actual amplitude of the signal with a handheld digital oscilloscope I have.

Read this:

https://github.com/nwdigitalradio/n7nix/blob/master/DRAWS_CONFIG.md The step where you run app_config.sh core setups up your image & starts direwolf from systemd. If you read to the bottom of the document you will learn the proper way to stop & disable direwolf and the ax.25 stack. Using killall leaves the ax.25 stack compromised and will give unpredictable results later on. /Basil Bob Orrett <boborrett@...> writes:

I hate to admit this but I don't know what is meant by "run Basil's scripts" Was I supposed to do something after the first boot up of beta6 ? Everything looks normal after the boot up. Exceot ft8 and js8call do not get access to the soundcard and I cannot seem to stop or start direwolf. Bob ve3obo

Thanks for the killall direwolf suggestion but I seem to have deeper issues. The response to that command was "direwolf: no process found" I have downloaded the Draws beta6 image about 3 or 4 times on different sd cards and direwolf does not seem to run, among other things. I do get the usual desktop for rspbian stretch. Everything looks great. Ft8 and jso call will not work. I have had them working before and I have made no other changes to the setup except a new image burned onto ghe sd card. I am at a loss. Must be the way I am burning it to the sd card. I am using etcher on windows 10. Bob ve3obo

John and Basil,
Good point on the appropriate scripts (not just killing direwolf)! I will be loading Beta 6 later today…
Suggestion: Is there any way these script functions can be put into/called by a “DRAWS/udrc control panel” app?
As it was in Beta 5, having Basil’s scripts scattered between ~/bin, ~/n7nix/bin, and ~/n7nix/debug made doing the set up and testing a bit of a challenge. Jumping around the different pieces of the directory tree made for some interesting “not found” errors.
Good work guys! We really appreciate what you are doing.

This will leave the AX.25 stack in a weird state, please use Basil's scripts to start and stop AX.25 and it will start/stop direwolf.
If you start direwolf without AX.25, then it can be stopped without AX.25

I noticed that killing direwolf on Compass Linux beta 1.5, ax.25 interface udr0 and udr1 are removed freeing access to draws sound card. sudo killall direwolf is a quite simple command indeed. Bernard, f6bvp Le 24/12/2018 à 04:48, Bob Orrett a

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. Joe K3JV

Excellent write up Joe. Did you adjust any other setting than adjusting ADC level in alsamixer for receive level? Outstanding post. Thanks for sharing Julian Julian OH8STN www.oh8stn.org www.youtube.com/c/OH8STN

Can’t speak for this implementation as I am waiting for the next DRAW run to be shipped. However my experience with other rpi implementations, my SD card contained a single image. I make sure by reformatting with SD formatter then burn image with etcher. You could try this approach. FWIW Art
