Re: DRAWS™ Latest Board Run Defect (Standby) #recall #draws

Thanks for all the info that's been shared!

Is there a way to identify the affected boards from the O/S?  GUI or command line either one?

Or, is it just every board with the SMA connector down at the end opposite the USB & ethernet jacks?

Thanks!

How do we check to see if our board is one of the affected boards?

Here is there info needed to address the problem:

The Audio output has an RC Filter of 100ohms and 0.1uF for a -3dB frequency of 16kHz.

The boards were stuffed with 10uF instead for a 160Hz cutoff.

The filter is not really necessary so the caps may be removed.


If you do the rework yourself, send an email to sales@... with REWORK <order#> as the subject and we will refund $10.

Or you may send the board only to:

NW Digital Radio
REWORK<order#>
150 Cessna Ave
Friday Harbor WA 908250

We will rework it for you and refund $5 for the postage

We have updated our manufacturing test to provide better coverage.

DRAWS Compass refers to the current and now deprecated image.
That image does not have piardopc installed.
The next image most likely will since I am working with paclink-unix &
ardop on the RPi.

I ask because I see ARDOP available in the drop down of PAT.

If not, what does it take to active the ARDOP install in Compass so PAT
would see it without installing it again (using K4KDR instructional
video, for example)?
John Wiseman's documentation is excellent and I had no problems getting
it to work with UDRC or DRAWS on an RPi.

http://www.cantab.net/users/john.wiseman/Documents/ARDOPC.html

Below are my brief notes for using an UDRC II. The only thing to be
aware of for the DRAWS hat is the gpio setting for left or right mDin6
connector.

Command line used to start piardopc

./piardopc 8515 plughw:1,0 plughw:1,0 -p GPIO=23

Added this to .asoundrc
ref: ARDOPC.txt

pcm.ARDOP {

Hey Ed!

I believe you're referring to the excellent YouTube videos from KM4ACK.

I can't speak to what might have already been installed on the DRAWS Compass
image in regard to ARDOP... all I did was follow the steps in the KM4ACK
videos for both ax25 & ARDOP and both methods are working perfectly for me.
(I am also using the DRAWS SD Card image but followed the KM4ACK steps to
get those 2 PAT protocols configured & working)

Re: DRAWS™ Latest Board Run Defect (Standby) #recall #draws

  Thanks for the update!

  Could this explain why my recent DRAWs board (2 weeks old) doesn't work at all with the default TM-V71A alsa settings that ship with your image ? I mean the `setalsa-tmv71a.sh` script. I had to create a very different set of settings in order to get other stations to demodulate my AFSK-1200 properly...

Thank you. That is what I was going to do next. But was not 100% sure. So I stopped and asked the question.

Networking is not my IT strong suit. I am an application programmer generally speaking.

My next thing to learn is how to create a desktop icon to run pat http.?? I also need to double check the ARDOP install.?? It is included in the DRAWS package but I an not sure if it is fully setup and available to PAT.

I will need to watch your video again to look at the connections to radio. I will using an FT-897.
