Re: Beta7 release announcement

quick point I started an audio settings thread for people to add their configurations to for comparison between different rigs and other audio notes.

one stop shop for sound level questions #documentation #draws #beta

Art - KC7SDA
 

Ok, so I think we needed one place with all of the definitions of each setting and its reasoning behind it.

I don't understand about the xk ohm resistor settings, nor what each setting is in the mixer and what it will change (ie this slider will change the overall output-speaker volume and this one will change the input on the left channel)
Also I want to share fldigi settings on this so we can troubleshoot and get them right for both the left and right channels

Please note, I'm assuming the din next to the gps is channel 1 (or 0 in direwolfs case) and the other din is channel 2

for fldigi, sound card settings are:
port audio: udrc both record and playback
on right channel tab, both reverse in transmit and receive are checked (this is for channel 1)
for gpio i'm using BCM pin 12 (GPIO 26) with the value box checked

now, for dumping the settings, the alsa-show.sh script is in the n7nix/bin directory (wasn't in my user bin), so if you have a set of settings that work, please post them, I'm interested in the variances between setups and what people find work the best, please include your radio and if you have to change settings (just say which ones and what direction, you don't have to post another list of settings)

I'll be dumping mine after I upgrade to beta 7 and run my test script

AllStarLink channel driver for UDRC/DRAWS

William Franzin
 

Good evening

Does anyone have a working channel driver for the UDRC/DRAWS board? I've borrowed a UDRC board and also have another controller based on the same codec and want to get them both up and running for AllStarLink.

Thought I'd ask before doing it .. With nice hardware like this it's fairly easy. Just need the alsa driver and gpio and we're good. The same thing exists already for BeagleBone using gpio.

Best regards
William

William,

 

Please let us know your experiences using the IC-7000 with the software you are trying to run. I need to compare my outcomes with other 7000 owners. I will be loading Beta 7 this evening to give it a try.

Re: JS8Call #js8call

Basil Gunn
 

You can determine the js8call version installed on your DRAWS image like
this:

dpkg -l "js8*"

Draws Beta7 image has js8call 0.12.0-devel

This js8call version was released Jan. 2.

Re: DRAWS and the FT-817 #ft817 #draws #ft-817

Jack Spitznagel
 

Basil and All,

I set up the FT-817, broke miniDIN6 pin #6 in a spare cable to nop the squelch. So, direwolf/Xastir did transmit sound at those original alsamixer and FT-817 settings below:

===== ALSA Controls for Radio Transmit ===== < (I just had to fix Tansmit to Transmit, compulsive speller!)
LO Driver Gain L:[-6.00dB] R:[-6.00dB]
PCM L:[-16.50dB] R:[-16.50dB]
DAC Playback PT L:[PTM_P3] R:[PTM_P3]
LO Playback CM [ Full Chip CM]

===== ALSA Controls for Radio Receive =====
ADC Level L:[-2.00dB] R:[-2.00dB]
IN1 L:[Off] R:[Off]
IN2 L:[10 kOhm] R:[10 kOhm]

The FT-817 [menu #25] DIG MIC is set 65 as was recommended.

However, using fldigi, the FT-817 was transmitting noise with high ALC with the settings above.

I played with the sound and rig input settings until I got to the following settings:
===== ALSA Controls for Radio Transmit ===== < (again)
LO Driver Gain L:[-2.00dB] R:[-2.00dB]
PCM L:[-8.00dB] R:[-8.00dB]
DAC Playback PT L:[PTM_P1] R:[PTM_P1]
LO Playback CM [Full Chip CM]

===== ALSA Controls for Radio Receive =====
ADC Level L:[-2.00dB] R:[-2.00dB]
IN1 L:[Off] R:[Off]
IN2 L:[10 kOhm] R:[10 kOhm]

The FT-817 [menu #25] DIG MIC is set to 25 instead of 65.
There is no ALC reading (1 bar or less), signal looked very clean on the panadapter scope and immediately had a QSO with HI8MU in the Dominican Republic and received RSQ of 599 - running 5W with a GAP Titan vertical on 20 meters. I think that qualifies as success.

Using the same settings had an wsjt-x FT8 20M QSO with KC9FLD in Dubuque, IA received a -22 report but no retransmits - I consider that a success. Again the ALC was one bar or less.

The changes in settings has no effect on direwolf/Xastir performance. I am going to alter the local script to set up the FT-817 this way. I won't have to re-adjust the FT-817 [menu #25] DIG MIC setting again since this is the new TNC/sound card. 😊

Now back to the IC-7000!

In one of the Radio App Notes: FT-817, a reference is made to a config file "setalsa-ft817.sh", but I don't see this file in my BETA6 load and it reports no file when run.

Where might I get this script(and maybe related files for the FT-817)?
The script setalsa-ft817.sh is supported in the BETA7 image which hasn't been released yet.

My kids bought me an Ender 3 for Christmas.  

Looking at the inside you can see that there are four supports for both the top of the DRAWS hat and the bottom of the pi.  The two tall screw towers are the only ones useable for fastening the case shut, which is non-optimal, but it actually fits snugly with no screws at all.

If you look at the scad file you can see how the powerpole mount works — there are tiny details that engage the roll pin holes.  It is easy to install and remove but it doesn’t come loose during use.  This detail was the main purpose of the case design.   Everything else got very little attention.

Please note that the design is a remix of Thingiverse 2985738

The good:
SCAD provided so you can help tune the design
Added a powerpole power port
Stretched the case to protect the power connector
The bad:
Extraneous screw holes that can't be used with DRAWS
GPS antenna connector is a stubborn fit, so there is a big gap
The ugly:
SD card protector dimensions are just plain wrong. The card is inaccessible.

The scad file was provided, I used OpenSCAD.

Fixing the card issue should be pretty easy. I didn’t care enough to reprint since I don’t need it, but if there is interest we can make it a customizable SCAD.

The only changes I would make is to move the screw holes to the bottom, and perhaps add protective wings around the GPS connector.
