The Barrel Connector was incorporated into the latest Boards. There is a PowerPole to 2.1mm DC Coax Cable available from Powerwerx

If you have an earlier board you can terminate the supplied JST XH Pigtail to anything you like, wether it’s coax, PowerPole, or whatever works for your application. Of course most of you have already done this.

These pigtails are available from Pololu and others if you need another one.

MAKE SURE TO CHECK POLARITY! as they are not all the same. RED on RIGHT

Best Practice is to Fuse the power link at the source 1-2.5A

Yes, the cases work with Pi3 or 4, here’s pics:

Great News. Will the the "early adopter" case work with the PI 4? The website photos are not displaying with an image of the case.  Looking forward to receiving it. Ordered it back when I running it on Pi 3.  Thank you.   JJ1PJI Kevin

Interested in buying the DRAWS kit from NW digital --

Sounds like a good application for some of the economic impact stimulus funds...

Interested in buying the DRAWS kit from NW digital -- when will it be
back in stock?

Thanks John!  I'll shoot an email over.

Hey Basil,

Thanks for replying.  That is the 6-pin MiniDIN adapter that I have.. I even tried my spare with no success.  It's had this issue from the start and I did get frustrated with it and gave up.  Just decided to pick it back up and give it another shot.
I've only ever had it out in the open without a fan.  It does have the heat sinks on it as well.  Luckily I've been on the list for a case which as a built in fan so hopefully that will work after the fact.

What would be the process if I do have a defective DRAWS hat?  It's had this issue from the start and I did get frustrated with it and gave up.  Just decided to pick it back up and give it another shot.

Re-stating your problem to see if I have it right:

CAT control is not working between an RPi 4 and and a Yaesu FT-100D
which is a multiband HF/VHF/UHF radio.
Connection is through a Yaesu CT-62 cable which is an 8 pin mDin to
USB serial device connection.

This has nothing to do with the DRAWS hat!

The most common problem is finding the correct Linux serial device name
for FLdigi/FLrig.

# With the CT-62 disconnected from the RPi find all current USB serial
device names:

ls /dev/ttyU*
ls: cannot access '/dev/ttyU*': No such file or directory

# In my case their are NO USB serial devices plugged into the RPi.
# Now plug your CT-62 cable into your RPi and execute 'ls' to find the
# name of the serial device.

ls /dev/ttyU*
/dev/ttyUSB0

# In this case the USB serial device name is /dev/ttyUSB0
# This is the device name to use in your FLdigi/FLrig configuration for
# CAT control.

Note if you unplug/plug your CT-62 cable in your RPi while it is running the
device name will change.

Thanks Basil for the rapid response,

That's good to know.  So, how do I get the frequencies to show up in the display and/or flrig?  The cat cable is CT-62 with USB end.  No serial-to-usb converters in the middle.

Eric,

Placing A Hold On Kernel Upgrade
* FOR REFERENCE ONLY, the current Linux kernel is safe to use with
DRAWS

You do NOT need to place a hold on kernel upgrade. That procedure was to
fix a problem that affected the DRAWS overlay last summer.

I will take this reference out of the 'Getting Started Guide' later on
today because that section was "For reference only, the current Linux
kernel is safe to use with DRAWS"

The drivers in the current kernel, 5.4.79-v7l+ #1373, works fine with DRAWS.

Hi team,
I've been having issues with the Draws hat and it is installed on a Pi4. I first tried getting it to work on KM4ACKs Build-a-Pi (Ham experimentation right?). Then I formatted my sd card and followed the getting started guide https://nw-digital-radio.groups.io/g/udrc/wiki/8921 for image nwdr18.img.xz ( http://nwdig.net/downloads/nwdr18.img.xz ) 2020-Dec-05 08:36:33 1.8G and got as far as the fldigi configuration. ax.25/direwolf appeared to work and sent/received appropriately. fldigi keys the radio (yaesu FT-100d attached currently to 1 watt to dummy load) but it appears my cat cable is not reading or setting the radio frequency so I also tried fiddling with flrig to no avail. I stopped here. Reading further:

--------------------------------

* For reference only, the current Linux kernel is safe to use with DRAWS

To verify your current kernel version

uname - r
*

You should see: 4.19.118-v7l+

*

If you see : 5.4.51-v7l+ then your DRAWS hat will have problems

* The driver for the TI ads1015 chip is missing in this kernel.

To revert your kernel back to 4.19.118 run the following (courtesy of Thomas KF7RSF):

sudo rpi - upgrade e1050e94821a70b2e4c72b318d6c6c968552e9a2

*

Do NOT use the following commands:

* apt-get dist-upgrade
* apt full-upgrade

What I saw was not kernel 4.19....
and n7nix's verify_config guide 'sensors' fails to show
ads1015-i2c-1-48
so I try

*

* sudo rpi - upgrade e1050e94821a70b2e4c72b318d6c6c968552e9a2

and get sudo: rpi-upgrade: command not found

I formatted (again) and haven't connected to network or configured anything.
First check of uname -r gives me 5.4.79-v7l+

Help, please and thank you!

Use deviation guide here:
https://github.com/nwdigitalradio/n7nix/tree/master/deviation

Running measure_deviate.sh will allow you to output a tone so that you
can use alsamixer to change the 'Lo Drive' & 'PCM' alsa controls.

I used the Argent Data 6-pin MiniDIN adapter for the Moto CDM 1250
https://www.argentdata.com/catalog/product_info.php?products_id=169
You have to be careful how you plug that into CDM 1250

It looks like you are using the right hand mDin 6 connector. Channel 0
is the left hand mDin6 connector which is the default connector for
using scripts to set up packet.

If you can't get enough volume using the measure_deviate.sh script you
may have a defective DRAWS hat.

The soft temperature limit bit is set in the get_throttled register.
The current temperature, 59C, is fine but at some time your RPi over
heated.

First off thanks for creating such a versatile board!

I've ran through the setup a few times and I'm still having the same low transmit audio problem.  I've tried it with 2 radios (FTM-400 & Motorola CDM1250).  I have to have my HT turned up all the way and I can still barely hear the data bursts.  I've tried adjusting through Manager as well as alsa from ssh and I'm not able to get much change.

Here is the output from my showudrc.sh:  https://pastebin.com/raw/krbtCAm8

We will announce ship dates on the blog and the groups.io site
