ThumbDV using Buster

jimfielder@...
 

Received my ThumbDV this week, fired up Buster, added my local reflector and boom.  Works like a dream, excellent sound coming in and have had excellent audio reports from those listening.

Love it when a product works like a dream.

Bryan, heard your lecture live from MicroHAMS last Saturday and found out about Buster for the Mac.  Ordered it on Monday and it arrived on Wednesday.  Nicely done all around.  Software and hardware - both excellent.

Thanks!

Re: Two products now and no UDRX-440

Bryan Hoyer <bhhoyer@...>
 

Hi Paul, actually it’s 3 products now with the UDRC.

The UDRX remains our top priority internally. The other products were actually developed to allow some of the UDRX features to be tested easier.

The PiDV was built specifically for the UDRX to add AMBE Vocoder to the radio. Releasing it first got D-STAR integrated and tested by others.

The ThumbDV was just a re-packaging of the PiDV for Flex Radio.

The UDRC was initially developed to have an easier cheaper platform for audio testing and shares Power Supply and Audio CODEC design with the UDRX. The software work has focused on building the automated build process and software delivery/update mechanism which will be used on the UDRX

The development work for these products did not use any UDRX resources. We remain totally committed to the UDRX. Each of these products has helped out by generating much needed revenue to support UDRX Development.

Keep the faith,
Bryan K7UDR

Great to see product diversification for NWDigitalRadio.  But, what is the status of the UDRX-440?  Yes I have seen the latest video demonstration but where in the priority line does the UDRX-440 sit regarding getting the product into the hands of those of us that initially signed up for a high speed 440 data radio?  Devices which expand the world of Amateur Radio via the internet are interesting but more and more Amateur Radio is just becoming part of the commercial infrastructure rather than Amateur Radio building radio networks.  The UDRX-440 has the promise of providing a different path for those of us that want to "play radio" versus a commercial infrastructure connection.

My UDRX-440 money still waiting to be spent....

Re: UDRC

"John D. Hays" <john@...>
 

Documentation is tied to product release.  

If one knows how to open audio devices under Linux and manipulate GPIO pins on a Raspberry Pi, then one has the basic knowledge to program the UDRC.

I use WiringPi for GPIO manipulation.  Source of the dstarrepeatercontroller will be generally available for examples.

On the HD-15 connector (used to connect to the DR-1X) there are unbuffered GPIO pins for:
  • COS and PKSQL (digital and 'analog tone' squelch) input
  • PTT and REMOTE (take over) output
  • 4 mode setting pins output

Audio:
  • Discriminator audio from the DR-1X
  • Audio from the DR-1X
  • Tone In/Modulator to the DR-1X
  • Audio to the DR-1X

Ground and Power (The UDRC and Raspberry Pi are powered from the repeater)

The mini-din 6 will follow amateur radio convention, however the control pins will be buffered because of potential voltage differences.

More advanced topics will follow basic documentation.

Is there some specific information you’re looking for?
How about an UDRC python layer on top of the standard python GPIO
library that makes it easy to turn on the PTT pin to play over the
local repeater the audio of K7UDR promising to have the the product
ready by last weekend.

I’m not sure what programming documentation would be applicable for the UDRC. It’s essentially just a soundcard. It will show up in ALSA just like any other sound card. It supports the S16_LE and S32_LE formats and the following sample rates:
8000
16000
22050
44100
48000
96000

Is there some specific information you’re looking for?

Re: Thumb DV Software

Be aware that using mbelib with DSD to decode voice likely violates patents. Use of licensed AMBE decoders such as PiDV or ThumbDV is recommended.

To use the SDR dongle as a D-star receiver use SDR# and get from http://www.wb9coy.com

 

 the Download DSD1.7 from projects.  This add on to SDR# will decode any D-Star, DMR or P25 signal that you hear automatically.

Re: Thumb DV Software

Bill Vodall <wa7nwp@...>
 

As a software developer I got EXACTLY what I wanted from the DV3000 and the ThumbDV.
I may have just given myself a reason to need several DV3000 or
ThumbDVs. If I understand this right, a rPI, DV3000 and a 25$ SDR
dongle is all it takes to make an all (>HF) band DStar Receiver.

Could take it to the next extreme and create an all band DStar
transmitter using the rPI bit banging output.

Yikes - two more projects...

http://nwdigitalradio.com/a-short-udrx-and-udrc-update-from-microhams-2016/

UDRC is a Raspberry Pi Hat to provide a high quality sound card and control (PTT, COS, etc.) for various hamradio modes.

UDRx is a software defined, band limited, 25 watt UHF radio for digital and digital voice modes.

Re: Will it work with plain vanilla ubuntu linux?

"John D. Hays" <john@...>
 

The short answer is Yes, if you get the USB version, the ThumbDV.

The longer answer.  Whether the PiDV (for GPIO connection on a Raspberry Pi) or the ThumbDV (USB), the DV3000 looks like a serial port.  It provides a transformation between (digitized) voice and AMBE and the reverse.  

Everything else is dependent on the software you use.  For Linux that will be a combination of DummyRepeater and ircDDBGateway.  Those programs are by G4KLX and are obtained and supported via Yahoo! Groups ... see  http://nwdigitalradio.com/thumbdv-and-dv3000-resource-page/

There was a message on the Yahoo ircddbgateway group a few months ago about changes to the repository location.  The latest instructions in the files area of that group have been updated to show:

# sudo curl
http://repo1.ham-digital.net/raspbian/opendv.list -o /etc/apt/sources.list.d/opendv.list alternative if this address should not work:

# sudo curl http://download.prgm.org/dl5di-soft/opendv/repositories/raspbian/opendv.list -o /etc/apt/sources.list.d/opendv.list

Hi Bryan,


No offence taken as I don't think I' that much of an idiot as I can download an image etc.

The problem I am having is finding an alternative source to the ftp one listed in the section on Installing IRCDDBGateway: from a terminal

(get installation packages, PGP Public Key, update packages, and install ircDDBGateway)

$ sudo curl ftp://141.75.245.226:8021/raspbian/opendv.list -o /etc/apt/sources.list.d/opendv.list

$ cd /


$ sudo apt-key add dl5di.pk

Hi Bryan,


No offence taken as I'm not that big an idiot as I can cope with the basics of copying an image etc.

The problem comes, I think, with getting confuse with which directory things need to be saved into and built.

I think I need to go back to basics, clear all the memory from the SD Card, reformat it, reload Wheezy and start to build again.

One problem I do get is that the FTP addresses don't work in the section on Installing IRCDDBGateway: from a terminal
(get installation packa ges, PGP Public Key, update packages, and install ircDDBGateway)

$ sudo curl ftp://141.75.245.226:8021/raspbian/opendv.list -o /etc/apt/sources.list.d/opendv.list

Are there any alternative sources?
You can try:

Watching with great interest.

Was just about to ask about possible TDMA ability (Tx/Rx switching speed), but just hear someone ask that very question :)
