Decoding FT8 #ft-8 #draws #wsjt-x

JT Croteau <jt.tobit@...>

#3684

Does the Pi 3B+ decode FT8 properly or should I wait on the Pi 4 for the faster CPU? I'm getting mixed reports from other Raspberry groups.

I already have a DRAWS and just waiting to see how the Pi 4 testing continues.

Thanks

Thank you. I tried on a pi without the hat and it did not boot.

Does draws 11 have the same isdue with updating?

People have been successful using DRAWS™ with the new Buster Raspbian (see thread on here). If you make a new image, be sure to backup your current image so you can roll back.

To all using an HT with DRAWS:

Clamp on Ferrite Beads are recommended on both ends of the Cable to prevent RFI from interfering with the Pi.

I tried when the DR-2X first came out with no success and have not heard of anyone having success with it.

You would need direct access to the discriminator, modulator, and PTT with no interference from firmware.

For anyone following along at home, I did get all the hardware working, ax25 configured and dire wolf configured.

I installed pat, and am able to get the LED on the draws to light up when pat is trying to connect over ax25, so as soon as I can build my 6pin din -> wouxun HT cable I can start seeing how it works.

Thanks to everyone for all the assistance.

Goodbye signalink, and hello pi+draws.

Re: DRAWS on Pi 3b+ with Raspbian Buster #draws

Jon Gross

#3673

Thanks!

What I ended up doing was basically this:

1. vanilla buster install
2. update all the things (apt update ; apt upgrade)
3. add snd-soc-tlv320aic32x4-i2c and ax25 to /etc/modules
4. add dtoverlay=draws,alsaname=udrc and dtparam=audio=on to /boot/config.txt
5. install ax25, gpsd, hamlib, and related dev packages with apt
6. compile/install dire wolf from source

The hardware is working (gps confirmed, radio interface not yet confirmed), and I'm still working on getting the ax25 stuff configured and direwolf wired up correctly, but I think the hardware is functional now, as I'm seeing the sound card and the gps is working great.

Thanks again for your help!

#3672

Aha! Thank you both.

Instead of running the n7nix code, I've been using it as inspiration, and gotten things to recognize the sound card, thanks to n7nix, Lars and Karl and all the docs that exist in the wiki.

I ended up doing a(nother!) stock buster install, adding the tlv* modules to my /etc/modules, modifying my boot/config.txt, and now it looks like it's on it's way to functionality.

I may add a page to the wiki with my approach in case someone else wants to do it by hand as well.

Thanks all!

#3671

Lars is faster than me :)

If someone get a similar problem with RPi4, you should note that there are two variants of the kernel involved.

RPi3 by default boot the -v7+ variant that Lars refers above.
RPi4 use the -v7l+ variant (the difference is the lowercase LIMA)

The name of the modules are the same, but the path to the modules is different.
When I moved mye SD card with Buster from a RPi3 to a RPi4 it automagically chose the right kernel.

Jon, I hope you get some help from all this. You could run `lsmod` and see if the two modules are loaded:
snd-soc-tlv320aic32x4
snd-soc-tlv320aic32x4-i2c
If the modules show up, you could see if there is any relevant info in `dmesg` that can give a clue why sound (and probably GPS) is still not working.

Good luck!

Karl

Re: DRAWS on Pi 3b+ with Raspbian Buster #draws

#3670

Hi Jon,

Your /boot/config.txt seems to be the same as the one on my RPi4, so that looks correct.

The 2 files Karl refers to that might have been moved to /home/pi/tmp, are

/lib/modules/4.19.57-v7+/kernel/sound/soc/codecs/snd-soc-tlv320aic32x4-i2c.ko

/lib/modules/4.19.57-v7+/kernel/sound/soc/codecs/snd-soc-tlv320aic32x4.ko

Brgds,

LA4RHA, Lars

#3669

Hi, Jon

I actually did a fresh install of Buster on a RPi3b+ while I was waiting for my RPi4 to arrive. So it is possible to run Buster on RPi3.
(RPi4 require Buster to boot, but the setup of Buster should be the same regardless of running on RPi3 or 4. I was able to just move the SD card over to my the RPi4 when it arrived)

The boot config can be a bit tricky. The lines need to be in the right order.
The drivers in Buster are already patched to work with DRAWS. However some of the scripts under n7nix/ are not updated for this, so if run they will move the in-kernel drivers out but not be able to build new drivers.
If this happened to you, you should see two driver files under /home/pi/tmp/

All this from memory. I will update with a copy of my boot config and exact name of the drivers when I get home. If noone else beat me to it :)

Best,
Karl LA9KOA

I can't seem to get the drivers to load properly.

Curious if anyone out there running buster on a 3b+ gotten the sound card to work?

DRAWS Update! What about the Pi 4?

by k7udr

The DRAWS HATs are in stock but the announcement of the Pi 4 has changed the landscape.

We have Pi 4s on order, and a few of our customers have DRAWS working on the Pi 4 now (see our support group for details). This proves out the connectivity, but 3 issues remain; power consumption, thermal requirements and mechanical design of the case.

Once we have Pi 4s on the bench, we will analyze these issues and make adjustments accordingly. The goal is to modify the case so it will work with either the Pi 3 or 4.

In the meantime we have suspended ordering of turn-key units. Kits will ship with the case backordered.

Matt,
You may want to reset the radio.
I have done that in the past when problems arise.
I use the included menu settings after I reset the radio.
I am using the left audio channel.
Have you checked the draws manager and make sure AF (pin5) for your channel.
Also make sure Direwolf is not running
