Re: Trying to set the UDRC2 pins and levels via the script

w5pfr@...
 

Is there somewhere that I can find the settings for the dstarrepeater, (not Gui) here? i changes the soundcard RXdevice to 0, and still not able to decode on two meters. 
most everything is set to 0, and the PTTinvert looks to be set to 1.

I have been changing them, but Dstar radios are not able to decode the signal coming out of the DR1X. 
The repeater does hear it and will TX the dstar signal, but non of my dstar radios are able to decode. (The infamous dv/fm flahsing)

Thanks in advance:
john 


Re: Trying to set the UDRC2 pins and levels via the script

 

If you are setting up for a repeater, you might want to try this approach. https://nw-digital-radio.groups.io/g/udrc/topic/4816993#1419

Then try the rest of the commands as if you had used cd ~ (~ means home directory). 

BTW you should change the password if your pi is accessible to the network.

Re: Original UDRC

N7MQ Steve
 

Well I've tried the web based install and a fresh install with an older image of compass and I still get the same error. "I/O error". There must be something wrong with my board. It is and original UDRC that has been knocking around. I'll get a different one and get it running then.

Re: DTMF Tones and UDRC

Matthew Wolf
 

There was zero interest in my area for a APRS Touch Tone gateway.  My UDRC II is now sitting in a drawer because it is not being used.

I routed the receive audio from two radios into direwolf. One radio for APRS and the second radio for  Touch Tones.  The audio output was split between direwolf and the festival speech synthesis system. One of the audio output channels on the UDRC was used by direwolf. The second output was used by festival.

Below is the asound.conf file I used to route the audio input and output.  

After the asound.conf is the direwolf configuration file I used.

Then after the  direwolf configuration are the two shell scripts that I used to generate the voice responses for Touch Tone transmissions.  

asound.conf:

pcm.card1 {
    type hw
    card udrc

pcm.dmix1 {
    type dmix 
    ipc_key 34521

    }
}
pcm.dsnoop1 {
    type dsnoop 
    ipc_key 34523
    slave {
        pcm "card1" 
    }
}

Re: Original UDRC

 

Steve,

I was looking at GPIO.7, which looks OK.  Sometimes when this is designated as a different mode it indicates a problem communicating to the UDRC.

Have you tried a fresh install?  There may be something elsewhere in the OS causing the problem with alsamixer.

Re: Original UDRC

Hi Steve.

I'm afraid that I am at a loss... You could try installing alsamixer again (sudo apt-get install alsamixer), but likely something else is missing.
It may be easier (rather than working out this problem) just to start at ground zero again with a fresh install of compass.
Also, I forgot to ask...are you running a GUI or just the CLI?

Re: Original UDRC

Hi Steve,
I've been running an original UDRC on a DR-1x for about a year and a half on a raspberry Pi 2, running Compass(Jessie). What do you see when you run alsamixer? Audio levels ( PCM, ADC) should be set to approx. 48(use this as your starting point).

Hello All! I am trying to setup the original udrc for a DR-1X. I am running 1.00z firmware on the repeater, but the trouble I'm having is getting the urdc to work. I just got the urdcii to work at home with a kenwood 750. That setup was straight forward and easy. This setup with the udrc and the DR-1X seems to partially work. When I start dstarrepeater it will not acknowledge any digital traffic but will suspend RPT State when FM is keyed.

Anyway the error I'm getting is:

pi@compass:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: udrc [udrc], device 0: Universal Digital Radio Controller tlv320aic32x4-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
pi@compass:~ $ sudo ~/set-urdc-dr1x.sh
amixer: Mixer hw:0 load error: Remote I/O error
alsactl: get_control:256: Cannot read control '2,0,0,PCM Playback Volume,0': Remote I/O error

The card is recognized by the system but I'm getting a I/O error when I try and load the script. Any help would be greatly appreciated.

73's,

Re: GMSK modem

Bernard f6bvp / ai7bg
 

Hi John,

Nano satellite project IgoSat from University Paris-Diderot will use GMSK modulation for UHF telemetry downlink (Isis VHF/UHF module).
An UDRC-II modem was kindly provided by NW digital as a backup for receiving telemetry.
I would like to experiment with GMSK between two RPi with UDRC II modems in order to prepare next generation students work in coming six months.
How can I change from default 9600 bauds FSK to GMSK  UDRC settings ?

Wow.  That’s what I get for not touching this for months.  Its alsamixer.  Dee dee dee.

So I did an apt-get update and apt-get dist-upgrade and now aumix is gone.  I installed it and now it cant find the mixer.  Are we not supposed to update?

Ritron VHF Data Radio Modules / FYI

Randy Neals <randy@...>
 

Slightly off topic, but an FYI on some data radio that may be useful for ham digital projects

I discovered these on eBay and thought I'd drop an FYI here to share.
5 Watt VHF commercial data radio module that would seemingly be good for digital VHF use.

http://www.ebay.com/itm/Ritron-VHF-Transceiver-PCA-136-156MHZ-5-Watt-Model-DTX-142-GCWD-I-/191557457767?epid=1448345366&hash=item2c99b6d767:g:qqcAAOSwrklVKx~S

Spec Sheet:
http://www.lauttamus.com/_pdf/TwoWayRadio/Ritron/dtxls.pdf

Service Manual:
http://hydrolynx.com/manuals/RTR-LS-VU.pdf

What I've learned thus far:

The manual says that the W in the model means it is Wide band.
That's probably why these are radio modules are available cheaply because most commercial radio systems now have to be narrow band.

Audio for Data Purposes:
Aux Audio Input pin 7 is 7-3000 Hz without pre-emphasis. 300mV produces +/- 3kHz deviation.
Aux Audio Output pin 8. When loaded @ 600 Ohms, output is 7-3000 Hz without de-emphasis. Higher load impedance will lower the low end frequency response.

Programming:
Looks like the Ritron software is pay-to-play.
Online radio sellers list the programming kit (cable & software) at $125.
Part number for the programming kit starts with DTXL-PCPK

Re: Yaesu DR-2X with UDRC

John:

Thanks for posting the detailed issues. Let's hope a future firmware update restores the discriminator audio.

Yes, I was talking about a firmware upgrade to an existing DR-1X, not a swap for a DR-2X.

Thanks,
Paul, K3PGM
