Heh, I guess it's all relative. :-) I'm used to a minimal image that basically just gets the machine booted with all the hardware usable. I suppose in UDRC/DRAWS terms, that'd be the necessary drivers

I've seen it crawl under Linux too. I was at work, so 50Mbps microwave link for Internet. Workstation and border router are both Linux (Gentoo on the workstation, Ubuntu on the border router), an inte

You might run afoul of one instance of Direwolf opening the ALSA device for the sound card and locking out the second instance unless you do some trickery in the ALSA configuration files to present th

Well, I've got mine just sitting bare at the moment, haven't done a lot other than tested receive with the board due to lack of time. My plan is to throw it into the top-box on a bicycle, it'll be int

Well, I tried it at first with my FT-897D, got no audio, then tried switching to an Icom IC-706MkIIG… still no joy. I was using arecord/aplay and netcat for testing. I have a Pi 3 with a UDRC-II board

The software I plan to use requires the SQL signal to key up PTT in a VoIP application. As stated in my original email: In short, I'll be doing FM and SSB voice via the DRAWS board. I'll have a look a

How do I read the state of the SQL pin if it's open-circuit?

Hi all, The DRAWS board arrived yesterday evening, and today I picked up a new Raspberry Pi 3 to connect it… so far things seem to be working but I'm yet to hook up a radio. Now, with the predecessor

Well, got it down, and now I see why it's 2.6GB in size… it's a full-blown desktop image. I usually like to start with a minimal image and add what I need rather than starting with a big image and hav

Hi all, Is there a mirror of the Compass Linux for the new DRAWS board? At the moment I'm downloading the "draws_beta13.zip" image off of nwdig.net. The Internet connection at my workplace is a 50Mbps

Hi all, Silly thought just occurred to me… one sore point with the Raspberry Pi is that the device provides no audio I/O apart from the PWM audio output. Now, the UDRC/DRAWS is a big improvement on th

WINE doesn't magically make a ARM CPU execute Intel 386 machine code.

If you want to avoid having to re-start tail, then use: tail -F /var/log/direwolf/direwolf.log This is a GNU extension, so not portable with BSD's `tail`, but `-F` means to follow the file name rather

If by "sound card", you mean a rather pitiful PWM-based DAC with minimal RC filtering, then yes, there's a "sound card". Not terribly high fidelity, and no ADC.

I wouldn't be drawing power for a fan directly off a 5V pin. The neighbours on that 5V bus may not appreciate the back-EMF the motor is liable to generate even if the current draw is small. I would su

Indeed. That, or I wonder if we can do something with hamlib, since FreeDV integrates with that. Anyone know if hamlib supports UDRC PTT? It is actually on my TODO list to get armhf builds of FreeDV g

[…] It should work. It is actually on my TODO list to get my little Raspberry Pi going with FreeDV. At worst, we might need to tell it how to drive PTT, and that should not be a hard modification. Act

Yeah, have a close look at the link. In fact, rename the file to have .html on the end and open it. Then please have a look at my earlier reply. ^^^^^^ Bourne Shell doesn't understand this.

That is a link to the directory listing. Yep, it is 'measure_deviate.sh', it links to the source code listing of that file. It is *NOT* the raw file, but a pretty-printed version for viewing in a web

You've downloaded a HTML file and you're trying to execute it as if it were a shell script. As the script in question lacks the initial #! characters to tell the shell what program is supposed to exec
