Re: Any update on availability?

 

Hi Andrew,

Boards are in FAB and we should have units in a couple weeks.

Re: RPi kernel upgrade problem

Basil Gunn
 

The lastest Raspberry Pi OS respository has Anna's fix to the driver
for the DRAWS sensors in kernel version: 5.4.51-v7l+ #1333

First determine your current kernel version for reference:

uname -a

If you previously put a hold on kernel updates then unhold them now:

sudo su
apt-mark unhold $(apt-mark showhold)

To verify there are no package holds pending run:

apt-mark showhold

It is now safe to:

sudo su
apt-get update
apt-get upgrade

Verify your kernel version, has it changed?:
uname -a

If your kernel was updated then run the following:

cd
cd n7nix
git pull
cd config
./bin_refresh.sh

# Force a sensor config file update
sensor_update.sh -f

You will now have an updated /etc/sensors.d/draws file which is
dependent upon kernel version & DRAWS fab revision.

reboot

# After rebooting verify sensor readings:

sensors

If you are starting a new installation there is a new RPi image
release, nwdr17.img, which has the updated sensor driver and
DRAWS sensor configuration.

Do NOT run draws-manager web app as it needs some work to be
compatible with the new sensors driver. The NWDR17 image has the
draws-manager daemon disabled.

Until further notice please do not upgrade the kernel on your RPi.

Linux kernel 4.19.118 is OK
Linux kernel 5.4.51 has MANY problems

Run this to get your current kernel version:
uname -r

The following commands will upgrade your kernel.
Do NOT use them for a while:

apt-get dist-upgrade
apt full-upgrade

Re: How susceptible is the DRAWS board to RFI? Metal Case required?

Mitch Winkle
 

Just last week, I took an RPi4 with the tiny fan in the lid of the plastic case (from CanaKit) out into the wilds of a military installation in the heat and humidity (and it rained almost the whole time).  I had it running for many hours shuttling data between HF radios in different places.  No issues whatsoever. They are a bit tougher than we give them credit for.  The thing bounced around in my car all the way there for hours of driving multiple times.

Re: AX25 Status Problem

Basil Gunn
 

Having the draws-manager error out will not affect ax.25/direwolf.
You probably should run and paste the console output of these commands:
manager-sysd.sh status
then:
manager-sysd.sh stop

This will give John more output to help him debug the draws-manager
problem.

I am more interested in if ax25-status came back OK or not in case the
draws-manager failure is a symptom of some other problem. Please cut &
paste the output of these commands:

aplay -l
uname -r
showudrc.sh
ax25-status -d

I am completely new to DRAWS, and I've run into my first problem. I am
attempting to run this with a Yaesu FT-891, and I'm using all the supplied

Open another console window to the pi and as user pi type:

ax25-status -d
After == failed & loaded but inactive units== you should see
0 loaded units listed.
This did not happen. Under that section, I see: " draws-manager.service

loaded units listed," what next? It almost sounds like there's some service
not running that should be running.

Re: Right Angle Power Connector

 

It’s 2.1 same as KPC3 and KX3 but the barrel connector is only on the latest rev.

Re: Right Angle Power Connector

Tim Ciesluk
 

I’m sorry. I re-read your question and realize you’re asking about the JST connector. I haven’t seen any right angle pigtails, but you may be able to replace the ‘socket’ or try to bend the pins at your own risk. Use jst connector as your keyword search.

Re: Draws image

Basil Gunn
 

Noobie question ..
Is the Draws image all that’s needed on the sd card?
Yes.
The DRAWS image starts with Raspberry Pi OS and does a small amount of
config to enable UDRC/DRAWS hat. It also installs a number of HAM
programs and provides configuration scripts for each.

Table of installed Programs here:
https://github.com/nwdigitalradio/n7nix/blob/master/docs/IMAGE_README.md

Terribly new to the Pi and programming.

And keeping the antenna as far away from the Pi as possible. Sometimes tricky using an HT.
Even harder on a bicycle… In my situation, it'll be mounted beside my
FT-857D which is inside a 44L motorcycle plastic top-box. I do
sometimes run 100W on SSB on the 80m, 40m, 20m, 15m, 10m and 6m bands.

The antenna mounts are to the sides of that same top-box (with an earth
strap for the HF antenna). So in that situation, the RPi will be
mounted barely 30cm from the base of the HF antenna (and maybe a little
further away from the 2m/70cm antenna).

Keeping RF out of the microphone (in my helmet) has been a challenge,
particularly on lower bands.

My plan is, when the case finally arrives, to earth that to the antenna
ground system, possibly even double box the thing in another case so I
can put some cable retention in as I can guarantee those mini-DIN6
cables will just shake themselves loose.

(We'll see how WiFi range goes, I only need it to reach about 10m.
There are ways to replace the on-board antenna with a socket. FCC be
damned, they aren't in charge in this country.)

It’s just the standard reference problem. Like a serial port. My TX goes to your RX


Re: Quick Q on interface cables...

Charlie Hein
 

Ok, Bryan, humor me here... looking at the mini-din pinout below, I'm a little confused by its nomenclature.  I think that what's labeled "data out 1200" is what should go to the "mic input" pin on the mic connector (see Mic connector pin out below).  Audio from the DRAWS board should go to mic on the radio.  Am I misunderstanding the direction that signals are heading out of the DRAWS?  Pretty sure I have everything else figured out.
