Re: Utilizing DRAWS to encrypt handheld radios

Steve Stroh
 

FH is a valid modulation method in Amateur Radio as long as the hopping pattern is published.

But DRAWS isn’t a radio, it’s more of a modem. It doesn’t really control a radio either. That would be a task for its companion Raspberry Pi computer.

I would use caution here. Part 97 includes several references to obscuring the transmission, other than coded commands for remote control devices.

Using encrypted radios is completely legal in the US.  the FCC rules are more based around the language of frequency and tx power.

Re: GPS Troubleshooting

 

Remember the LNA in the antenna is powered through the coax, so make sure you are not disrupting the path.

Re: GPS Troubleshooting

Mike,

Machine has been on for over 24 hours...gps antenna in same position
that previously allowed to to receive all the satellites. Receiving
no sats. I am now going to attempt a third antenna.
I've noticed that on some of the RPi cases I use, the case prevents the
sma connector for the GPS antenna to attach properly.
If you do not get a GPS lock in 15 or 20 minutes then power cycle, move
the antenna and try again.

Doing the Sensors command I get the following...

pi@draws:~/bin $ sensors
rpi_volt-isa-0000
Adapter: ISA adapter
in0: N/A

ads1015-i2c-1-48
Adapter: bcm2835 I2C adapter
+12V: +13.66 V
in5: +2.52 V
User ADC 1: +0.00 V
User ADC 2: +0.00 V

What is in5: and is that a good number behind it?
I have notes on the 8 pin auxiliary connector here:
https://github.com/nwdigitalradio/n7nix/blob/master/docs/DRAWS_AUX_PORT.md

in5 is GPIO pin BCM5.

Re: Utilizing DRAWS to encrypt handheld radios

 

DRAWS™ can be used for amateur and non-amateur applications. NW Digital Radio has some non-amateur customers, but I am not aware of any encryption application.

DRAWS isn't limited to use by Amateur Radio users.

Re: GPS Troubleshooting

Basil Gunn
 

Hi Mike,

I have 6 DRAWS hats in test. 5 are on all the time, 1 is in my truck so
gets powered on every few days. A couple of hats have been on for over a
year most of the hats have been in test for over 6 months. All hats have
CR1220 batteries. So far I haven't experienced the problem you are
describing.

I ping'ed Bryan about this and he said that the battery has around a 40
day life span if the RPi/DRAWS hat is not powered on.

Look here for commands to verify GPS
https://github.com/nwdigitalradio/n7nix/blob/master/docs/VERIFY_CONFIG.md#check-gps

If the gps is not working for some reason your RPi system time will
eventually be set by the chronyd daemon. Type the following to see the
sources chrony is using to set system time: chronyc sources

Once the gps has satellite lock the time displayed with gpsmon should be
correct as well. You should get a lock within 15 or 20 minutes IF your
gps antenna is in a reasonable place.

The easiest thing to do may be to head up to Amazon and get some new
batteries.
https://www.amazon.com/Maxell-CR1220-Lithium-Batteries-5-Pack/dp/B0014WUYWC/ref=sr_1_5

Hope this helps.

I know I saw some troubleshooting steps here a while ago.

First of all I pulled the battery, and it was down around half a
volt...it was brand new when I put it in a couple of months ago, and
the draws has pretty much been powered most of the time...so that 40
day battery life unpowered is not a thing...OR it is 40 days per
battery, powered on or not.

As I remember, if you can't get satellite info, you try running it without a battery etc.

So Basil, could you refresh my memory on GPS troubleshooting?

(Mine had been working fine till maybe a day or two ago...powered up most of the time)

So now the system time is correct including date...but the time/date
listed on gpsmon is 2026-02-11...and I believe this is what happens
when the onboard RTC loses power...and it will correct itself
eventually (24hours?)

NWDR16 image release announcement

Basil Gunn
 

Latest RPi image current_image.zip has been updated to nwdr16.zip at
this location: http://images.nwdigitalradio.com/downloads

There were 8 image releases last year. This is the 2nd release of
2020, there may be one more this year.

You do NOT have to download the latest image to run the lastest
kernel/programs. You can get the most up-to-date kernels/programs by
doing the following with your current running image:

sudo apt-get update
sudo apt-get dist-upgrade
cd
cd n7nix
git pull
cd config
./bin_refresh.sh

You can verify & update image program versions with these scripts:

./bbs/bbs_verchk.sh
./xastir/xs_verchk.sh
./ax25/ax_verchk.sh
./gps/gp_verchk.sh
./hfprogs/hf_verchk.sh

The hf_verchk.sh script maintains current versions of these HAM programs:
js8call wsjtx flxmlrpc fldigi flrig flmsg flamp fllog

Current version numbers of programs on the image are kept here:
https://github.com/nwdigitalradio/n7nix/blob/master/docs/IMAGE_README.md

Before you update your image, capture any configuration changes you
might have made like current alsamixer settings. Run alsa-show.sh &
make a copy of result.

It is recommend having at least 2 mSD cards & not over writing your
current mSD card. NOTE: MINIMUM recommended microSD card size is 16GB.

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

The current image has Linux kernel (4.19.97) that includes Anna's main
line TI tlv320aic device driver which supports the UDRC / UDRC II & DRAWS
hats. To view the changelog for this kernel go here:
https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.97

Included in this image is gpsd ver 3.20.

NOTE: Direwolf version 'dev 1.6 E' has a problem building & running
with version 3.20 gpsd since the gpsd program updated their API version
number which is NOT handled by direwolf.
See reported issue here: https://github.com/wb2osz/direwolf/issues/241
If you use direwolf as an app that uses gps instead of just a sound
modem do not use this image, or install gpsd version 3.19.

On first boot, if you have an attached monitor, you will see the piwiz
configuration screen used on current 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 with this image please include:
- output of script showudrc.sh with your problem description.
- *ALL* console output showing the problem

Changes since last release:

* Image NWDR16 release
* Packet:
* Fix BBS install script & version check for version 7.0.9
* Add aprx install script
* Add missing Xastir run time library
* Fix RMS Gateway stat directory permissions.
* Add support for APRS client nixtracker
* Add alsa settings support for Alinco DR-x35 radios.
* Fix Setting direwolf SSID to 10 as already used.
* HF:
* Fixes for ardop-start, ardoplist.sh & ardop_install.sh
* ardop & arim functional install working
* Update all HF programs to current versions.
* Both HF & packet:
* Make split channel work on HF for right mDin6 connector.
* Fix split_status.sh
* Make some alsa settings scripts UDRC II aware

Re: Image NW 16

Hi J P,

Been a little unfocused lately. As my dog would say "Is that a
squirrel?" I have a nwdr16.img candidate but started playing with BBS
software and using a ThumbDV for a stand alone D-Star connection. Also
looking at using socat for connecting paclink-unix to FLdigi
kiss-over-IP interface.

I will work on the nwdr16 image over the next week.

BTW on Saturday I will be tuning into the MicroHAMS virtual Digital
