Re: Adding a second radio

Basil Gunn
 

I think you want a second ax.25 channel, which should already be
configured.

In a console run this:

ifconfig
or
ip a show

You should see ax0, your first ax.25 channel on the left connector & ax1
the second ax.25 channel on the right connector.
You need to set the baud rate you want (9600) in /etc/direwolf.conf
under "Channel 1 Properties". Change the MODEM 1200 line to MODEM 9600.

By default the left & right channels are always configured so it
shouldn't be too difficult to get the second channel going. The hard
part is that 9600 baud packet requires you to set deviation more
precisely than 1200 baud packet. Having access to a service monitor
helps.

Let me know how you make out.

You can add the second channel in direwolf.conf

Similar to udrc-ii


Use DRAWS™ Manager to set left and right radio channels.

Thanks a million for the secondary download location, William.

Pulled down a copy and just booted the Pi-3 / DRAWS to take a look and make sure I had followed the correct setup sequence.  Looks like the DRAWS is recognized & all ready to use.

Many thanks to Basil for putting v14 together!

Hopefully I won't fall too far behind, but for now I'll continue with the card I have fully setup from the last v13 image.  With everything configured & working so perfectly, I just want to keep using it as-is for the moment.  I've manually installed or configured the latest versions of everything I use (Direwolf, PAT Winlink for ax25 & ARDOP, JS8Call, WSJTx, and all the other stuff), so I really don't want to re-do everything on a new system at the moment.  I like to stay current as much as everyone else, but it's so nice to have a good portable system that "just works".

Appreciate everyone's effort on the project!

-Scott,  K4KDR

Basil,

I have a Raspbian Buster RPi 4 running the desired kernel. I want to

Not sure why you would want to do this as the provided image has already
done the heavy lifting of the install but if you really want to, look at
this file for instructions:
https://github.com/nwdigitalradio/n7nix/blob/master/docs/CORE_INSTALL.md

Building an image will take a few hours to a half a day depending on how many
problems you run into. Then a few days of testing to confirm it works
the way you think it does.

I suspect there is no file n7nix/config/image_install.sh installed
anywhere on my system. Correct me if I a wrong, please.
Correct. Read CORE_INSTALL.md link above.

Your instructions in the Wiki under "Make your own Raspberry Pi image"
stop after creating the Raspbian image, much as I have done. There
are no instructions on how to proceed after that.
Correct. I really do not want to support making your own image.

In an earlier post I saw instructions that may be what I am looking
for, but they were prefaced by "off the top of my head." If those are
the instructions, I would prefer that they are a bit more verified and
part of the official Wiki instructions before I make trouble.
The CORE_INSTALL.md contains (most of) the instructions I use to build
an image. It is not as straight forward as you think. ie. gpsd in the
Raspbian repository has problems so I build the latest from source. Also
in order to build FLdigi you must increase swap space. There are
probably another half dozen or so things that you need to take care
of. This is why there is a provided image.

Having said all that I understand the reasoning behind making a more
minimal image for things that do not require a window manager like an
APRS digipeater or an RMS Gateway or if you just want to run HF programs
like js8call.

If you look at the config/image_install.sh script you should be able to
pick the things you want in an image that fits your requirements. If you
go this route please know I most likely will not answer your questions
but it is a forum so others might.

Glad to hear you have things working!!

The ./btest.sh script runs OK (packets seen on aprs.fi) too on port
udrc 1.
I originally made this script as a quick test for packet using any of
the hats UDRC/UDRC II/DRAWS.

I still have to fix up the location finding via gps as on the udrc II I
have a BU-353S4 usb gps not the draws device. Although gpsd is running just
fine, the position data parsing provided in btest.sh is looking for NMEA
sentences, while I am fairly certain my device is not NMEA by default.
I wanted the btest.sh script to work for UDRC/UDRC II hats ie. without
the on board GPS so I just conditional'ed the GPS stuff based on hat
type. Please hack this script to make it do what you want. I have both
gpsd & nmea functions in that script.

After that I will takeon the APRX install....
Yes, APRX is the way to go for APRS gating/digipeating.

Since you have a working configuration why not save it to a file &
compare it with the configuration you are using with the new image.
ie. save /boot/config.txt, alsa-show, ax25-status -d

You could try a transmit test to see what that gives you
cd
cd n7nix/debug
./btest.sh -P udr1 -p

Remember that on a UDRC II the mDin6 connector is port 1 not port 0.

I notice that you have manually edited /boot/config.txt. I did not

Re: NWDR14 image release announcement #beta #support

Dave,

The "DRAWS specific software" are two codec drivers that are in the Linux
kernel and an overlay that loads at boot time.
The drivers are:
snd_soc_tlv320aic32x4_i2c
snd_soc_tlv320aic32x4

The overlays are either: udrc.dtbo or draws.dtbo depending on which hat
you have installed.

While there is some specific configuration required to take advantage of
the DRAWS hat gps & A/D converter all the other software provided in the
image are scripts that install or configure other software that could be
used by any sound card or serial/i2c TNC.

Most everything that I do to create an image I do with a script. See
n7nix/config/image_install.sh. That's only mostly true because there is
always some futzing around with a new Raspbian distribution to get some
things to work properly.

Perhaps you could explicitly state what you want to do and I can provide
some guidance on how to get there.

NWDR14 image release announcement #beta #support

Basil Gunn
 

Before you update your image, please capture any configuration changes
you might have made like current alsamixer settings.
Run alsa-show.sh & make a copy of result. Note a minimum
microSD card size of at least 16GB is recommended.

Latest RPi image current_image.zip has been updated to nwdr14.zip at
this location: http://images.nwdigitalradio.com/downloads

Please follow the "Getting Started Guide" from the UDRC Wiki.
https://nw-digital-radio.groups.io/g/udrc/wiki/DRAWS%3A-Getting-Started

This image has a Linux kernel (4.19.66) that includes Anna's main line
TI tlv320aic device driver that supports the UDC / UDRC II & DRAWS hats.
This means you can more easily make your own images.

On first boot, if you have an attached monitor, you will see the piwiz
configuration screen currently used on new Raspbian images.

If you are using a Raspberry Pi 4 and your monitor is blank then add
this to /boot/config.txt to use HDMI safe mode.
hdmi_safe=1

If you have any problems please include the output of script showudrc.sh
with your problem description.

Changes since last release

* Image NWDR14 release
* Use Raspbian Buster (Debian 10) with main line tlv320aic driver as image base
* Compass is deprecated
* Updated all HF programs
* Updated 'Getting Started' guide
* Fix permission problem when installing iptables
* Made beacon scripts independent of gps.
* Add script to easily switch between 1200 & 9600 baud packet.
* Add script to change RPi led trigger method

Re: image update failure

Basil Gunn
 

John,
I verified that the following method also works.
Copy the following alsa control values from your working image,
you can read them by running alsa-show.sh.

LO Driver Gain
PCM
ADC Level

Boot your new image and run:
cd
cd bin
sudo su
./setalsa-udrc-din6.sh

Now run alsamixer and set LO Driver Gain, PCM & ADC Level. To make
things more convenient you could use an editor and set the 3 values in
the setalsa-udrc-din6.sh script. They are the first 3 levels set.

Verify by running alsa-show.sh one more time.

sset 'IN1_L to Left Mixer Positive Resistor' '10 kOhm'

Since you have a working configuration why not save it to a file &
compare it with the configuration you are using with the new image.
ie. save /boot/config.txt, alsa-show, ax25-status -d

You could try a transmit test to see what that gives you
cd
cd n7nix/debug
./btest.sh -P udr1 -p

Remember that on a UDRC II the mDin6 connector is port 1 not port 0.

I notice that you have manually edited /boot/config.txt. I did not

Re: image update failure

Basil Gunn
 

First, beacmin.sh was meant to be a minimum beacon command and doesn't
have any arguments. That means it only outputs to the first port (udr0)
which will not work on the UDRC II unless you edit the AX25PORT variable
at the top of the script. The btest.sh script is similar to beacmin.sh
but provides command line arguments to select some things. This is the
script you should use when testing a UDRC II

/btest.sh -h
Usage: btest.sh [-P <port>][-s <num>][-p][-m][-v][-h]
-P <portname> | --portname <portname> eg. udr0
-s <num> | --sid <num> set sid in callsign, number 0-15
-p | --position send a position beacon
-m | --message send a message beacon (default)
-v | --verbose display verbose messages
-h | --help display this message

Second, the APRS symbol is two characters. The first is the symbol table
identifier and the second is the symbol code from that table. If you
look at the beacon_msg variable in either beacmin.sh or btest.sh you
will see that the first character is between ${latdir} & ${lon} and the
second character is between ${londir} & $timestamp.

For more information look at the APRS manual around page 24.

Did you set your alsa settings the same as what you had on your
working
BETA10 image?

yes.
It is very clear that the attached radio is receiving aprs packets.
There is likely something obvious I am missing ...?
I think that your ALSA audio routing is incorrect.
If you route through ALSA IN1 then you are using DISCOUT or
discriminator audio. If you route through ALSA IN2 then you are using
AFOUT or
compensated audio (preemphasis/deemphasis). Verify how your radio is
configured. On my Kenwood if I select DATSPD 9600 I am selecting
DISCOUT. This works well for both 1200 & 9600 baud packet.
This is not clear to me. I have tested the RPI3/UDRC-II controller to 2
different Yaesu radios both of which work fine with the beta 10 version.


Could you please return the console output of:

Re: image update failure

Basil Gunn
 

I used a new image (nwdr14) with a UDRC II and it worked fine. I will
release that image today. The only thing I changed from the scripts was
to select discriminator out using the alsa commands. You can do it from
the alsamixer gui as well.

sset 'IN1_L to Left Mixer Positive Resistor' '10 kOhm'
sset 'IN1_R to Right Mixer Positive Resistor' '10 kOhm'

Since you have a working configuration why not save it to a file &
compare it with the configuration you are using with the new image.
ie. save /boot/config.txt, alsa-show, ax25-status -d

You could try a transmit test to see what that gives you
cd
cd n7nix/debug
./btest.sh -P udr1 -p

Remember that on a UDRC II the mDin6 connector is port 1 not port 0.

I notice that you have manually edited /boot/config.txt. I did not
manually edit any files for my UDRC II test.

Did you set your alsa settings the same as what you had on your working
BETA10 image?

yes.
It is very clear that the attached radio is receiving aprs packets.
There is likely something obvious I am missing ...?
I think that your ALSA audio routing is incorrect.
If you route through ALSA IN1 then you are using DISCOUT or
discriminator audio. If you route through ALSA IN2 then you are using
AFOUT or
compensated audio (preemphasis/deemphasis). Verify how your radio is
configured. On my Kenwood if I select DATSPD 9600 I am selecting
DISCOUT. This works well for both 1200 & 9600 baud packet.
This is not clear to me. I have tested the RPI3/UDRC-II controller to 2
different Yaesu radios both of which work fine with the beta 10 version.


Could you please return the console output of:

Draws Hat with Cooling #case

Frank Ivan
 

Hello Everyone,

I have updated my case and it is Thing 3897403 https://www.thingiverse.com/thing:3897403.  It uses a Raspberry Pi Poe Hat between the Raspberry Pi and the Draws Hat.  This brings a temperature controlled fan blowing on the Pi's CPU and also is sealed so that hot air can't recirculate back through the fan but must exit through the cooling slots.  Again - can be printed for Pi3 or Pi4.

Case for Raspberry Pi 3b or Raspberry Pi 4b + NWDR DRAWS hat with GPS port on side.

Added PoE Hat as temperature controlled fan - keep Pi cool no matter load

SCAD file provided so you can help tune the design

STL files for both Raspberry Pi 3b or Raspberry Pi 4b print your choice

Has a powerpole power port

Nice fit for DRAWS card

Rounded corners

Machine screws into card spacers hold case together

 

Hardware

4 M2.5 x 8mm hex socket head machine screws (8mm does not include head)

4 M2.5 x 15mm female to female spacers

4 M2.5 x 8mm male to female spacers

4 M2.5 x 25mm hex socket head machine screws

1 Adafruit ADA2223 - 8.5mm header 40 pin stacking header - also available on Amazon

1 4 Pin Extra Tall Header - https://thepihut.com/products/4-pin-extra-tall-header-push-fit-version-poe-hat

 

1 Official Raspberry Pi Power over Ethernet card - must be official Raspberry Pi PoE hat

Available on Amazon - but PiHut is cheaper and you may want to get 4 pin header from PiHut

 

Assembly

Clean out screw holes - 7/64 or 3mm bit does it nicely

Clean out ports

Install Powerpole connector - maybe use a bit of thin double stick tape to hold in place

Install DRAWS card in lid. It's a close fit but should not be difficult

Push M2.5 x 25mm screws into holes

Slide baffles into slots - keep fan power notch on right as you look from back to front of lid

Install 8mm spaces on screws coming though Draws card

Install 40 pin spacer header into PoE Hat with header pushing into header on PoE Hat

Install PoE Hat onto Draws card - you may need to work the hat past the baffles

Install 15mm spaces onto screws coming through PoE Hat

Plug Pi into Poe Hat - make sure it is aligned with the pins go into correct holes

Install base

Secure with the 4 M2.5 x 8mm screws

Tighten every thing up with allen wrench

 

The PoE Hat will keep a Ri4 down to under 60C under extended load.  It easily passes the heating test from the Explaingcomputers YouTube videos testing Raspberry Pi4 B cooling.

While the PoE Hat is primarily used as a cooling fat, but a nice side effect is you can power the system from the ethernet port.

Note: If you need RFI shielding line the inside of the case with copper foil tape. 

Enjoy and 73
