Re: Pi-4, Dire Wolf and Signal Link---Where did the "Audio Device Settings" Go?

Mike Erstad
 

Hi John,
I’m trying to configure direwolf to use my Signal Link usb and I need the “Audio Device Settings” that are normally found in Preferences…

I just recently found how to install the Audio Device Settings back into the Raspberry Pi…

Code: Select all

sudo apt install -y pimixer
And then to launch it:

Code: Select all

pimixer
This allows me to choose and set up Audio Codec Device…
But as you mentioned in the “latter” I’ll try that to see if I don’t need this Audio Device Settings application or Preference and use your method...

Thanks Very Much
Mike

Hi Mike,

My setup is also Pi4, Direwolf, xastir and Signalink USB.  I'm not sure I understand your question, though.  Is the Pi4 trying to play system sounds out of your Signalink or are you trying to configure direwolf to use the Signalink?  If the former, use raspi-config as described here (https://www.raspberrypi.org/documentation/configuration/audio-config.md) to send system sounds out of your HDMI or headphones output.  If the latter, use the"arecord -l" and "aplay -l" commands to discover which device number your Signalink was assigned and "alsamixer" to adjust the settings (if needed). Portions of this video (https://youtu.be/9Ya0C308TQA) are helpful in figuring out how to configure the direwolf.conf file based on the values returned from the"arecord -l" and "aplay -l" commands.

I hope this helps.  73

I believe pimixer may have been removed from latest Raspbian for some reason.
You can install it with:

See the 2nd photo here for what the HamProjects folks did with their BRIAN product.


That's essentially the same path that I've followed.

Good question about 9600 baud packet. The DINAH page talks about selecting between 1200 and 9600, and the PCB has a jumper on the bottom for it, so one could assume that it's been tested.

Re: New MFJ TNC-PI (maybe) ALTERNATIVE at Less Cost.

KP3FT
 

It's true the same thing can be fabricated cheaper, which is what I do here, but for $35 the DINAH is actually a good deal.  A big plus with the DINAH is that the onboard GPIO pin on the CM108/119 chip which can be used for PTT by Direwolf, SoundModem, and others, is already set up for PTT.  It's extremely difficult to solder to that pin when home-brewing... and the pin isn't soldered to the board itself on the Ebay sound cards (at least the ones I've worked on), so it breaks off very easily if the wire isn't secured first.

One trick when homebrewing with the Ebay cards is to not remove the IN/OUT jacks and instead loop the wires through them for strain-relief, and solder to the pads on top of the jacks.

Re: configure tnc-pi on polaric server(java app)

hi

Randy:VE3YRG
Yes, this is one of the problems that I detect.

you cannot use pitnc_getparams or pitnc_setparams if RF is enabled on the polaric server. This will generate conflict with the port.
if you use it, polaric is not able to open it because there is a lock file from another application.

im using

2. 5.    yes i enable serial port and disable serial console, so i can access tnc pi  ,
3. ttysS80 was a test to simlink another number. . . . . .

sudo usermod -aG uucp pi

Have they been tested at 9600 baud packet?  It appears there are caps in the audio paths so that may limit the bandwidth needed.

Re: New MFJ TNC-PI (maybe) ALTERNATIVE at Less Cost.

Martin Cooper
 

And the point I was making is that DINAH is basically just a USB sound fob, so of course it can be used with Direwolf, just as almost all sound cards can. As for cost, I personally feel that $35+ for a USB sound fob kit is rather a lot when I can buy one that works well for a couple of dollars on eBay and modify it for a dollar or two in parts. However, I do realise that many will appreciate the prebuilt and pretested nature of DINAH, especially if they want an Allstar interface.

I do agree that interesting things are happening, and that the PiHat is one of those interesting things.

Re: configure tnc-pi on polaric server(java app)

David Ranch
 


I have a few ideas for you since you sited you have the TNC-Pi running in serial port mode to a Rpi 3B+:


1) You listed the permissions of /dev/serial0 but that's only a symlink.  What is the permissions of /dev/ttyS0?

2) Is the serial console function on your Rpi still enabled if you're using the TNC-Pi in serial mode?  It must be disabled to not interfere in communicating with the TNC-Pi

3) Your cited error of "RXTX fhs_lock() Error: creating lock file: /var/lock/LCK..ttyS0: El fichero yaokt. 22 08:39:28 ERROR (TncChannel): [rf0] Serial port /dev/ttyS80 not found"
talks about port /dev/ttyS80.  Why S80?  Is that a typo in your config?  Typo in your error report?

4) For the Unix account you're logged into, is it apart of the "dialout" group?  This is commonly required when not running programs via the root account.

5) Did you disable bluetooth and reconfigure the hardware BCM serial port to connect to the GPIO header?  https://www.raspberrypi.org/forums/viewtopic.php?t=253552

6) What distribution are you running on your Raspberry Pi?  Do you have gpsd or modem-manager installed?  Either of these might be trying to take over the serial port by default.

Symlinks are already set up by the raspberry pi OS.  You should have 2, /dev/ttyAMA0, and /dev/ttyS0.  One should point to /dev/serial0 and the other to /dev/serial1

Re: New MFJ TNC-PI (maybe) ALTERNATIVE at Less Cost.

Martin Cooper
 

DINAH has been around for a while, as have its relatives, BRIAN and SHARI. If you've seen any of the numerous posts around the web about how to modify a USB sound fob for Allstar, that's essentially what DINAH is, except that they've designed their own USB sound PCB with those mods built in, and packaged it with a 6-pin mini-DIN socket for convenience.

BRIAN is effectively DINAH packaged together with the innards of a Baofeng BF-888S radio. SHARI is the same thing, but using a NiceRF SA818 instead of the Baofeng.

The DINAH is available as a kit ($35+$8 ship), or assembled ($45+$8ship) and comes with a 6pin to 6 pin DIN cable that plugs into many 2-way ham radio data ports, such as my Yaesu FT-817 or Kenwood TM-V7A.  Preliminary as it is, it is less expensive that the MFJ.

They also make a SHARI - same idea except it comes with a 300-500MW VHF or UHF transceiver for local operation.

So let the experimenting begin.....

They also make a SHARI - same idea except it comes with a 300-500MW VHF or UHF transceiver for local operation.

So let the experimenting begin.....
