John,

It is a DV3000 pic header. 

Also thanks for the info on the not O but 0. Makes more sense. I will give it a try.

Re: DStar Tinkering

 

Hi Rob,

The PiDV and ThumbDV are AMBE encoder/decoder devices and don't have anything to do with RF directly.  You can  get on the D-STAR network with them using software on your computer and connecting via the Internet.  The Wiki is a good start.  https://nw-digital-radio.groups.io/g/ambe/wiki/AMBE-Devices

Unless you are building a dedicated AMBEserver on a Pi, the ThumbDV is more flexible since it can plug into the USB port on a variety of computers.  https://nw-digital-radio.groups.io/g/ambe/wiki/AMBEserver-Addendum

Re: dsdcc

Steve <kb9mwr@...>
 

Some things I have noticed; Apparently you need the mbe library even if you use a AMBE dongle... I wasn't able to get around this dependency.  On the other side of the coin, apparently you also need to build serialDV even if you don't use it. 

We were able to get dsdccx to work with the NW digital dongle. But not without, as we get the "Error writing to output" repeatedly if not using the ambe3000 dongle.

And lastly I don't know if its just me but RTL devices on the Pi seem temperamental, as I get PLL not locked often.  Wonder if its related to no real time clock or something.

Here is a basic guide.

Wondering if anyone has tried it? I recently tried giving it a go on a Raspberry Pi 2 (not sure that will have enough snot), but ran into endless problems with dsdcc and its output to the pi sound. I get "Error writing to output" when when I try and tell it to use-o ( Audio output device) hw:0,0 .  Same error after I install alsa-oss and do the modprobe to enable /dev/dsp.

The prior version of dsd supports port audio, this one doesn't appear to.

thumb dv set up

Jp Colville <colville500@...>
 

I need help setting up my thumb dv. can get it to connect but I don't hear anyone I'm not sure what to do. do I need to register with someone to start? what are the gateway settings to use. pretty new to this so if someone can start from the beginning that would be great


Re: New gnuradio repository for the AMBE3000 devices

 

I have added a couple of new blocks to the gr-ThumbDV OOT so that a more-or-less complete DStar receiver can be built. See the included image. I'm now thinking about what I need for DMR rf flow-graphs...

I guess these blocks should work with the PiDV as well. Somebody will have to let me know...

Re: ThumbDV vs DVDongle

 

Check out his blog post about the original dongle:


There is a newer dongle, DV3K, which is essentially the same as the ThumbDV. FTDI + DV3000

It’s normally $150 on sale for $145

The ThumbDV is $120 on sale for $100

Re: PiDV or ThumbDV - for D-Star repeater?

 

A D-STAR repeater keeps everything in the digital realm. Audio is neither encoded or decoded in the repeater. 

No AMBE device is needed the UDRC provides the modem and control via the dstarrepeater program. 

Otherwise the PiDV and ThumbDV are functionally the same. They just have different serial connection types.

Re: New gnuradio repository for the AMBE3000 devices

 

Okay, it really wasn't that difficult to design a "bare-bones" DStar transmitter with the addition of a few standard gnuradio blocks. By "bare-bones", I mean no DStar header, slow-data or termination flag. A commercial receiver might complain a bit, but it will receive and decode the audio just fine. A flow-graph for this simple transmitter is now included.


New gnuradio repository for the AMBE3000 devices

 

I have a new gnuradio OOT (out-of-tree) repository, gr-ThumbDV, at http://github.com/ac2ie.

This repository will build two blocks for encoding and decoding audio data. It can use either the AMBE-3000 DStar vocoder or the DMR vocoder. Additional AMBE-3000 vocoder methods can be easily added. The AMBE-3000 has dozens of available methods.

These are very basic blocks. No additional info is encoded or decoded. The encoded data will be about 35 times smaller than the original audio data. Each 160 16-bit audio samples is converted to 9 bytes, and vis-versa.

By themselves, these blocks are not suitable for building a DMR or DStar transmitter or receiver. My intention is to build additional blocks in this repository that will, when combined with these blocks, allow you to construct a DMR or DStar receiver or transmitter. While my other repository, gr-ambe3000, is more monolithic and for DStar only, this new repository will be more modular and flexible.


Re: ThumbDV with GnuRadio

 

Yes the PiDV is a serial device at 230400 -- though with the ThumbDV sale right now, it might be the better buy?

I'll leave to others, their experience with GNUradio on Pi 3, but I believe that it works.

On Wed, Dec 14, 2016 at 4:01 PM, Tom Early <ac2ie@...> wrote:

Short answer: I have no idea. I don't have a PiDV. If it's on a serial port and can do 230400 or 460800 baud, then maybe.

Are you trying to run gnuradio on a Pi? I'm not sure that's going to work very well, especially if you want any kind of reasonable bandwidth to/from you rf sink or source.
