Re: ERROR ON gps

Jack Spitznagel
 

When I was trying to install Xastir, exactly the same occurred to me after I tried to invoke X from inside a terminal window with the command “startx” while running the GUI already.  I found the only solution was to blow away the image, create a new one and write it to the microSD card with Etcher, the start to configure all over again.
Sorry I can’t be more helpful.

Re: DRAWS downloadable Image? #setup #compassimage #draws #earlyadopters

 

Art,

We do test the DRAWS Hat on HF and have it working on different radios.  Obviously, we don't have every model of radio or physical wiring configuration.  However, there are tools and advice to try and diagnose what is happening in your specific installation.

Mostly, it is making sure that the "UDRC" (and DRAWS) sound CODEC is visible to the applications and setup properly.  As Bryan said, there are software controlled switches to help select which pin on the DIN-6 are used to input audio to the CODEC.  Then there is level setting.  We provide scripts to initially set the values on the CODEC, but a particular radio may need adjustments to be made.

There is a tool at https://nw-digital-radio.groups.io/g/udrc/wiki/Generate-a-Tone-to-Set-Radio-Deviation-via-the-UDRC%E2%84%A2 that can key the PTT and send a tone (mainly used for checking deviation on FM but the tone generation will work for other modes as well).  

A good description of your setup may help us and others (who have similar setups) to advise you on getting this working.  The key is to write it up, then step away for a while and then come back and read your writeup as though you knew nothing about it and make sure it has all the details that one would need to debug, then send it to the forum.

Re: Draws Analog to digital interface

 

Rick,
I guess I am not sure what you are looking for?  The sound CODEC on the DRAWS Hat can certainly convert analog audio to digital analog (typically PCM) and back.  Transcoding and routing is a separate function.

I would like to get more information on a local hardware based interface if available, dmr is not a concern since we have interface to decoded through Brandmeister and there are very few DMR users in southern Indiana.

Any options will be an depreciated and explored.

This is a functionality that is typically done in software.  You might look at the Allstar Digital http://lists.allstarlink.org/cgi-bin/mailman/listinfo/allstar-digital  or MMDVM software stack.

The DRAWS Hat can connect up to your analog radios/repeater.  There is also a version of MMDVM in process for DRAWS (it won't do a DMR repeater [because of TDMA] but it can be a hotspot for DMR  -- on the others it can be a repeater or hotspot).

Re: DRAWS downloadable Image? #setup #compassimage #draws #earlyadopters

 

Is Direwolf running? You can’t run Direwolf and FLDIGI at the same time.

This is a sw issue that we’re working on.

Hi John, while this works for Dierwolf on VHF/UHF radios, the mixer settings are not working on HF radios using FLdigi , WSJT-x, or JS8call.
See my other posts to Bryan on this issue, the work around posted does not work either.

The TX only supplies a low ticking noise , and no RC audio from the HF radio is getting to any of the applications.

There should be a space between /dev/ttySC0 and /dev/pps0 in the gpsd config.

Re: ERROR ON gps

 

The space goes between the 0 and the /. Those are file names for two different devices. When you run them together, you are creating a file name that doesn't exist and so the program can't open it.

The first thing you need to do after burning the compass image and booting the Pi for the first time is to edit the config.txt file:

$ sudo nano /boot/config.txt

go to the bottom of the file and change the last line dtoverlay=udrc to dtoverlay=draws  save the changes

Then reboot and look here $ cd /dev  then $ ls you should see a long list look for ttySC0 and pps0

ttySC0 is for the gps serial port and pps0 is for the pulse per second.

Re: DRAWS downloadable Image? #setup #compassimage #draws #earlyadopters

Jack Spitznagel
 

Brian,

Is this the same issue I see below?

I have had what seems to be a similar issue after using the provided Alsamixer script then trying to use direwolf (and xastir) with both FT 817 and IC 7000 on 144.39MHz. All I hear is a a very very short and slightly noisy key up when direwolf tries to digipeat a packet from my main AGW system on the home workstation. I have played with the transmit audio controls, but nothing brings up the TX audio level.

The Draws setup is receiving flawlessly but is essential “mute”. Xastir sees incoming packets and maps them, but can’t key the system at all. Direwolf key without sound and way to short

If the solution is not in your explanation below, can you point me to where to properly set audio and extend the keyup and keydown times before and after the audio payload. (txdelay and hang time after packet has been TX)?

Hi Art,

Yes I know what the problem is.

DRAWS has an analog mixer in the Front-End to switch between Discriminator on Line-In 1, which is typically used on VHF/UHF Rigs and Audio on Line In 2 which HF Rigs use.

To switch the input in alsamixer set IN1_L to off and IN2_l to 10 kohm
It’s the same for the right channel

Hi folks, wonder if anyone else ran into this? 
Built FlDigi and installed JS8Call. Before I ran the SH script to set DAC levels, I had perfect TX tones on PSK31 and JS8call but no receive audio.
After running the SH script to set DAC levels , I get TX low level background noise only in the transmitted audio;  and still no RX audio into FLdigi or JS8Call.
Have set FlDigi capture and playback to UDRC hw-0,0  and also default to test. Both same results.

This is tested on both my FT-891 and FT-817 in data modes. CAT control was easy as I had set that up before on "other" PI and Tinker Boards before.
Plugging in my Signal Link into the Pi/radio(s) the audio TX/RX is perfect from USB Audio Codec.

Opened Alsa Mixer and moved the UDRC Capture and playback ADC levels, nothing changes at all.
I am using the left 6-pin connector on the Draws board as specified by the board detail pic.  Switched to the right to test to make sure. Used both supplied cables to make sure one was not bad.

The first thing you need to do after burning the compass image and booting the Pi for the first time is to edit the config.txt file:

go to the bottom of the file and change the last line dtoverlay=udrc to dtoverlay=draws  save the changes

Then reboot and look here $ cd /dev  then $ ls you should see a long list look for ttySC0 and pps0

ttySC0 is for the gps serial port and pps0 is for the pulse per second.

Not sure if I follow you on missing a space,it looks as though all letters are correct but not sure about space.Linux is new to me,a challenge brings back the old DOS days.But I am persistent.
Thank You

Hi Bryan, I made those changes suggested as below. No differance ; tiny tx audio noise, no water fall no receive of audio from radio.

#  Turn on AFOUT
sset 'CM_L to Left Mixer Negative Resistor' '10 kOhm'
# original sset 'IN1_L to Left Mixer Positive Resistor' '10 kOhm'
sset 'IN1_L to Left Mixer Positive Resistor' 'Off'
 
#  Turn on DISCOUT
sset 'CM_R to Right Mixer Negative Resistor' '10 kOhm'
sset 'IN1_R to Right Mixer Positive Resistor' '10 kOhm'
 
#  Turn off unnecessary pins
sset 'IN1_L to Right Mixer Negative Resistor' 'Off'
sset 'IN1_R to Left Mixer Positive Resistor' 'Off'
# original sset 'IN2_L to Left Mixer Positive Resistor' 'Off'
# original sset 'IN2_L to Right Mixer Positive Resistor' 'Off'
sset 'IN2_L to Left Mixer Positive Resistor' '10 kOhm'
sset 'IN2_L to Right Mixer Positive Resistor' '10 kOhm'
 
sset 'IN2_R to Left Mixer Negative Resistor' 'Off'
