Re: Error compiling dv3000d for NWDigital DV3000 AMBE board

Bob Nielsen <n7xy@...>
 

No. there is no template for configuring but there is a Makefile. K7VE has been helping on the ircDDBGateway list and at his suggestion I copied settings_raspbian_armhf.mk to settings.mk and it for a half-hour or so but then complained about "cannot find -lusb-1.0” during the linking process. John thought I might be missing portaudio19-dev but I do have that installed.

I did a lot of Fortran IV programming some 45 years ago but never learned C++.

Error compiling dv3000d for NWDigital DV3000 AMBE board

Bob Nielsen <n7xy@...>
 

I received my DV3000 yesterday and have installed it in my Raspberry PI running Rasbian (Debian wheezy-based Linux). I installed libwxgtk2.8-dev and portaudio19-dev. Following the instructions in http://nwdigitalradio.com/preparing-the-raspberry-pi-for-dv3000-applications/dv3000d I copied AMBETools-20140519 to my home directory and unzipped it. However, when I try to compile, I get the following error:

My card arrived today (that was fast, but it helps to be in northwest WA). It’s going to take a bit of reading before I am able to use it but hopefully I’ll have it going in a few days. I wish the GPIO headers on both boards were a bit shorter so it would fit inside my RPi case, but that’s a minor nit, since I will be moving it to the UDRX-440 when that ships.

Re: [pcrepeatercontroller] DV3000 Info

In that case, a simple USB<->Serial converter might work?

These are cheap and commonly available for working with microcontrollers (e.g., Arduinos in 'bare' form).

Hi Adrian,

We don't currently have any plans to offer the DV3000 in a USB or other factor.

However, as Jonathan points out.  The implementation of the dv3000d on the Raspberry Pi (and hopefully the Banana Pi) makes the device available over a network using UDP without some of the issues and headaches of the USB interface.

The GPIO interface is to a simple UART  (Gnd, V+, TX, RX, RTS) and if you can match the voltage and baud rate, then interfacing with other processors and adapters is pretty straightforward.

Hi Folks

As promised at Dayton here are the new AMBE Tools programs. One of them, DVToolReader was included elsewhere, but has now been upgraded considerably.

This suite consists of six programs, two are GUI based, DVToolReader and DVToolWriter and the rest are command line. All can work with either the DV-Dongle or the new DV3000 from NW Digital Radio. At their root these programs are designed to convert audio data to and from WAV files to either .dvtool files for the VoiceTransmit program, or for the announcements within the repeater, or to .ambe files for creating your own "Linked to" announcement, or even time ones. In all cases the WAV files should be mono and sampled at 48000 samples/sec.

The settings for wav2ambe and wav2dvtool are taken from DVToolWriter, and for ambe2wab and dvtool2wav from DVToolReader.

In addition DVToolWriter can record a microphone straight to these file formats.

Like the newly released Dummy Repeater, these programs can use the DV3000 which is hosted on a Raspberry Pi, and the same comments about the dv3000d running on the RPi apply.

For some reason, I can't upload my files to Berlios so the only source for the software is currently via this group.

Dayton Hamvention

NW Digital Radio announced, today, immediate availability of the DV3000 AMBE card. 


There is a Hamvention special for $89.00, which will be honored for 1 month or until current inventory is exhausted (about 100, er make that 90 units).  You may purchase at http://nwdigitalradio.com/shop 

This is the same card that will be used in the UDRX-440 but may be used with the Raspberry Pi.

Jonathan Naylor has adapted DummyRepeater and several wav / AMBE conversion utilities, which will be in his next beta release (Monday or Tuesday).

SVN users can get the code now, but there is a minor change that will be necessary.

Hi Paul,

Some very thought provoking ideas.

These are good tools for the community to start thinking about.  To that end, it is our plan for the API to include socket access to the modem, as well as many of the system metrics that would aid such tools.  As a small company, we will not be able to develop every tool that the community will want or need, but will support developers who wish to undertake their creation -- part of our commitment to an open architecture.

The processor is capable of running Python, C, JavaScript/NodeJS, etc. using standard Debian Linux interfaces and tools.

As we prepare for Dayton, our schedules will be pretty busy through the rest of the week.

Watch for some news from Dayton on Friday.  [ Sorry, it will not be that UDRX-440s are shipping :( ]

Brian,

The remote location may or may not have internet access.

The general concern for me is how do I prove that the initial
installation is good - the grounding, cabling, connections etc - then
add the RF emitter, and then the RF path - so that when I walk away from
a remote site installation I only have to be concerned about the RF
path.

I would like to see some general usage installation tools which would
provide a "good to go" check list. This means being able to locally
loop back a few megabits of data with no errors and then do the same
end to end over the RF path. Not all installations will be created
equally and it would be nice to be able to identify where data link
errors are injected into the UDR-X network...is it the installation or
the RF path?

I have used a Firebird and Fluke network equipment to do end to end
testing and I thought there must be software applications that can also
do some of the testing done with such equipment checking "keyboard to
antenna".

It is my understanding that the UDR-X is not full duplex so looping back
from RF output to RX input, using a RF signal sampler - Microlab / FXR
type - is not possible. So, the alternative is to use two UDR-X units
which adds additional complexity to the testing procedure but is better
than nothing.
The ability of the modem and emitter to operate full duplex certainly is
the ideal local test procedure without having to "go on the air". Using
two UDR-Xs would accomplish the same goal.

For end to end testing over the RF path here again full duplex would be
ideal. However, something similar could be accomplished by a store and
forward application running at the remote end. The local end would TX a
data stream of N bits and the remote end store and then TX back the bit
stream to the local end. A checksum, SNR, BER, and constellation
display application would give RF path quality.

There seems to be quite a bit of info on the internet regarding python,
ipython, matlablib, SNR, BER and linux. So, if the UDR-X computer is up
to the task then the possibility of general usage installation apps
running on it to test an installation looks promising....or maybe adding
a Raspberry Pi might also work.

Lots of things to think, do and have fun with (;

Looking for ideas....

Hi Paul,
When you say remote location, I assume you have no network access,
only RF

Looping 25W back into our receiver would be a bad idea. :) Looping the
modem
would just tell you the processor is running.
Do you mean more of a digipeater mode where received packets are
stored then
re-transmitted? We could disable checksum to guarantee a response for
analysis
locally.

As part of the Hi-Speed effort, we are building a channel sounder for
testing
purposes. This is a PN generator designed for analysis.
The easiest thing to do would be to put the remote UDR in sounder mode
and use
your local UDR to analyze the received data which includes RSSI and
BER.
Constellation is an internal design tool at this time, but we will
provide the
hooks to some enterprising WebGL folks for display.
The results could be logged locally. We could also run sounder as a
chron job
(telemetry or beacon) then you'd get results even if you couldn't
successfully
talk to the remote unit. A few second burst hourly would be
interesting.

Great topic. What if you had several internet connected UDRs receiving
results
for comparison?
I'd like more input, I think this topic has a lot of merit.

Yes, it's the RTL stick that I was thinking about (I have a few of these already). I'm interested in the high speed modes that are now being developed, rather than the existing 1.2 and 9.6 kbps low speed data modes.

Watching and (eagerly and maybe a little less than patiently?) awaiting release and delivery. :-)

Use an rtl stick (dvbt usb stick)

Then your favourite sr software (be it hdsdr, sdrharp or whatever)

Route the audio to "soundmodem" and you can receive 1k2 or 9k6 packet

Would it be possible/practical to set up GNUradio and a cheap SAT-TV SDR
dongle as a quick, portable test set for the UDR's transmitter?

It would be receive-only, of course, but having half the test gear with
you is better than none. :-)

I could certainly be done in 'spectrum analyser' mode, but it would be
interesting to be able to at least receive and decode the beacons or
packets that are being sent.
