Sample Cases Have Arrived for DRAWS Workstation

The DRAWS Workstation Case

We are excited to give you a preview of the new DRAWS Workstation with it's beautiful red and black anodized aluminum case.  We have received our first manufacturing samples, and they look great.

As with any new design, there are some minor adjustments that need to be made before production. We are in the process of generating those change orders and they will  be in the hands of our OEM shortly.  This whole process, from change orders, to manufacturing, to delivery, will take approximately 6 weeks.  Look for cases in March.  We will open orders for the case once the production run is initiated.

The MSRP for the case will be $24.95.  As a thank you to our early adopters, we will offer the case for $19.95 for a limited time. (Standard shipping, plus sales taxes for Washington residents will apply.)

We will also announce pricing for the kit and fully assembled versions of the DRAWS Workstation in the coming weeks.  Details to follow.

Power Solution:

After much research, we have settled on a 5.5/2.1 mm Barrel Connector. This is the same connector used by the KPC3+, Elecraft KX3, and other consumer electronics. There are many 12VDC power supplies available with this barrel connector pre-installed. (You may even find a few in your junk box!)

The cases will ship with the panel mount socket which is soldered to the pigtail supplied with the DRAWS board. The first run, early adopters will need to modify the connector on the board slightly to fit in the case; we'll supply an app note. The next, and future, runs will not require any changes.

Powerwerx offers a standard cable to Anderson Powerpoles: DC21ST $7.99

The DC Jack is bonded to the case.

This looks excellent, and should help keep RF away from the RaspPi.

Will there be provision for a small grounding lug somewhere so i can bond the case to station ground, perhaps just a small extra hole somewhere that would allow me to add a #6 or #8 bolt ??

For portable use, the size and  price point and features of the FT-891 is hard to beat.

The Yaesu FT-817/817ND/818 are popular QRP rigs for portable use.  We have a couple on the air with DRAWS™ and with a good antenna work quite well. (Given 5W or less output).

HF Rig Recommendations #hf #draws

Ed Bloom, KD9FRQ
 

As I eagerly await the arrival of my second DRAWS, I am looking for some basic HF rigs that I can use for primarily for Winmor and ARDOP in parallel.

I was considering the micro Bitx unit with the JackAl mod along with the soon-to-be-released amp add-on.  The primary reason for this option is initial cost. A small bonus is that I get to build a little.  But I am open to all options accept the $15k SDR rigs.

Do you have any other rig recommendations?

Thanks.             73s, Ed, KD9FRQ "Freq" Radio

Re: IC-7300 with USB CAT control problem corrected in Beta 7 #draws #fldigi #gpsd #wsjtx

Thanks for finding this.
USBAUTO="true" in /etc/default/gpsd is an error.
That line has been removed in the BETA8 image.
See below.

The goal was to control an IC-7300 with a USB cable and operate fldigi, wsjt-x, and JS8Call using the radio's sound card. DRAWS received the audio fine, but would not control the radio. The IC-7300 was on ttyUSB0, but the command "stty -F /dev/ttyUSB0" returned the "device or resource busy" error. Unable to find the culprit I installed lsof with this command: "sudo apt-get install lsof" and ran: "sudo lsof /dev/ttyUSB0". The response showed that ttyUSB0 was being used by gpsd.

The Wiki directions for setting up gpsd read as follows:
Update, or create, the configuration file, /etc/default/gpsd, using a text editor, and set the following values:
START_DAEMON="true"
DEVICES="/dev/ttySC0 /dev/pps0"
GPSD_OPTIONS="-n"

I checked the file and it looked like this:
#Configure gpsd
START_DAEMON="true"
USBAUTO="true"
DEVICES="/dev/ttySC0 /dev/pps0"
GPSD_OPTIONS="-n -G"

So, I commented out USBAUTO="true" and rebooted DRAWS. Now "stty -F /dev/ttyUSB0" reported the port speed at 115,200 so I issued "stty -F /dev/ttyUSB0 19,200" to get the speed to match what was set in fldigi and on the radio. I created a symlink between /dev/ttyUSB0 and /dev/IC-7300 for a persistant name and now the CAT control works fine with fldigi, wsjt-x, and JS8Call (ver .13).

The question now becomes is it necessary to hotplug gpsd with
"USBAUTO="true"?
No. The draws board uses devices /dev/ttySC0 & /dev/pps0 to control the
GPS chip and NOT a USB device.

If not, perhaps rather than comment out the line I
should have used USBAUTO="false"?
If USBAUTO is commented out, gpsd config defaults to USBAUTO="false"

I would very much appreciated some
input on whether I need to make further corrections to this
configuration to insure that gpsd runs correctly.

Many thanks for DRAWS. What a fantastic product!

Re: Enclosure

Budd Churchward
 

Nice job! I am glad the file worked for you. That extra hole on the side of the case is for a barrel jack that will fit inside the case and hook up to the power leads that came with the board. I believe that the next batch of DRAWS boards will have the white JST power connector point up instead of out, which will make adding the power jack to the case even easier.
 
The key on the top is supposed to mate with another one just like it and provide a stacking mechanism if you have more than one case. I had room for two pieces with each case on the UDRC version, but I could only fit in 1 with this version. But if you have two cases, you will have two pieces and they will work fine.

That's a thing of beauty. I'd love a couple, eventually, when/if they're available. I have a DRAWS from the original shipment, and am waiting for a second my partner, K3XS, ordered. They'll both need cases.

The DRAWS™ HAT is just the board and some cables.

The DRAWS™ Workstation will be available as a partial kit or a fully assembled unit (with SD-CARD, case, etc.)

Re: Beta 7 stability #draws #fldigi

Basil Gunn
 

My suspicion is either a memory leak somewhere in the software stack
or heat. Both of those just because I haven't any better ideas.
To determine if you have a memory leak:

Run top

If you are using increasing amounts of swap space you probably have a
memory leak.

run top like this (batch mode, 1 iteration) to get a snap shot of
process memory usage. Save the output and run it at different times to
get an idea of what maybe eating memory.

If you have problems with your RPi freezing:

- upon the first boot capture your /var/log/syslog & /var/log/syslog.1 files and look for the
last entry before the first boot entry. ie. look for log entries before
a line that looks something like this:
Feb 1 10:56:05 drawstest kernel: [ 0.103179] vc-mem:
phys_addr:0x00000000 mem_base=0x3ec00000 mem_size:0x40000000(1024 MiB)

- try ssh from another computer to log in. If you can, then this tells
you the Window manager may have locked up. Now look at your syslog files
while the Window manager is currently unresponsive.

- On your other Linux computer run the 'arch' command to display the
machine architecture ie. x86_64 or armv7l. Saying that fdlog_enhanced
runs differently on a different Linux architecture provides useful
information.

I am not running FLDigi for long periods of time but I have a couple of
packet gateways that run continuously with DRAWS with no problems.
