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?

hank for replying. I can not open alsamixer it gives me this error.

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).


Original UDRC

N7MQ Steve
 

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

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.

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 ?

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

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


Re: Yaesu DR-2X with UDRC

 

It looks like pins 8,9 and 19 plus gnd for  basic interface and you can power udrc and pi off the the 13.8 vdc out. (11)

I would have expected Yaesu to work with Repeater Controller manufacturers and have Beta Tested the DR2X like they did with the DR1X and SCOM. 

They don't have manuals, so we can't determine what the intended mode of operation is for the DR2X. And without knowing how it's supposed to work, we can't really file a bug report - maybe it's intended to work that way.


My own approach...

I'm using Icom FR-5000/FR-6000 commercial repeaters as my amateur repeaters.
I'm currently studying/planning how to interface a UDRC-II using either the DB-25 on the back, or if that lacks the signals I need, the UC FR5000 dPMR/IDAS networking card slot on the back of the repeater.

A really awesome outcome would be a plug-in card that slides into this repeater with a Raspberry Pi and UDRC-II integrated, but that would be challenging to produce in small volume.

eg. Further explanation what I'm talking about.

Well....after repairing the DR2x (had an internal connector that 
wasn't seated all the way), we found other (and bigger) issues.

The bigger problem seems to be the lack of discriminator audio out - 
as it turns out, Yaesu changed the firmware so now BOTH RX audio 
outputs (discriminator on pin 8 and de-emphasized on pin 9) are now 
gated by the DR2x's internal CTCSS/DCS decoder. That is to say that 
if you have the repeater set to either CTCSS or DCS, no audio is 
delivered externally unless the input signal has the proper 
tone/code. This is a huge problem (in the DR1x, audio was available 
regardless).

Another issue is that the logic used to select AMS/FM/C4FM on the 
back panel DB15 is different than the DR1x, therefore the ADR will 
NOT work with the DR2x without changes to the programming of the 
ADR's CPU. In fact if one goes by the DR2x manual, it is not even 
possible to force the repeater into analog mode at all anymore but we 
are experimenting with that. It will do AMS and output what it 
receives however (analog > analog, analog > C4FM, C4FM > C4FM)

Back to ye olde drawing board.....

Hi All

It appears the DR2x we received the other day has some problems as no 
signals seem to be available on the back panel DB15 (used to 
interface with an external controller). There is no COS indication, 
no discriminator audio, no CTCSS decode indication, etc. As such we 
are unable to do any meaningful testing.

I have personally been on the phone this morning with the tech staff 
at Yaesu, including the appointed "expert" and we're attempting to 
work our way through this (although they have indicated they really 
have little on-hands experience with the DR2x and no service manual 
is yet available). They did indicate that if we (Arcom) wants to 
troubleshoot the problem as we can, they're fine with that and we 
will attempt to do so as we have time. Obviously we cannot answer at 
this point, whether the ADR works properly with the DR2x or not.

I also asked a customer who also has a DR2x to check for signals on 
the back panel connector and his appears to have COS but not 
discriminator audio so he likewise is dead in the water for now.

I'll let everyone know what progress we make on this (if any).

Ken

Do you know whether it's a fundamental limitation with the DR-2X, or more of a question of additional engineering on your end?

At this point it is fundamental in that the pin that is supposed to provide discriminator audio doesn't decode -- but, I haven't had a chance to figure out if this is fundamental or can be overcome.
 
I noticed from the manual that EXT ports 1 and 2 are interpreted differently on the DR-2X, which would certainly break things; are there other issues?


Yes, I will have to address those with special cabling, but if I can't get clean discriminator all bets are off. I think we are OK on transmit, but won't really know until fully tested.

Also, there is the question of interplay with the LAN card (I have one installed, though I have tested with it disabled and enabled).
 
On a related note, we were about to send one of our DR-1X units with a UDRC-II attached back to Yaesu for an update; should we hold off because of potential issues, or are the problems you observed specific to the DR-2X?


I assume you would remove the UDRC-II before sending it in.  Is this just an update (eg. firmware) or in exchange for a DR-2X?  If just an update, it should be fine.  However, if going to DR-2X, I cannot recommend it at this time.
