ThumbDV used as an AMBE Server

TG9AOR
 

Hello Community. So as to check if I understand correctly, it is possible to insert the ThumbDV on a USB port on my Raspberry Pi 3 that has a DVMega installed. System is Compass Linux. So I may install AMBE Server as described in the Wiki, set it up as Repeater 2 on ircDDBGateway (Repeater 1 is the DVMega), and access it from wherever with my dummy repeater program on my personal device. Did I understand correctly?


Thanks.

Ambeserver setup issues

Abbot Carder
 

Hello,

I am having issues while following the instructions on this page. I am using the suggested develop of load. Every time I get to the test I get this error message. I am not sure what I am doing wrong or not doing.



Thanks for any help.

Thanks for all your help John. I believe I have my system up and running.

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

I play around on 2m packet a fair bit and am interested in checking out what DStar has to offer.  I'm always interested in means of getting MOAR SPEED out of these rigs.  


Is the PiDV plus my existing RPi2 boards a good option to dig in and start tinkering?  There are a few DStar repeaters around me.  I have two 2m/70cm FM-only radios and am not sure from the documentation how the PiDV interfaces with them or if it's a transmitter itself?


Is there a good starter document out there?

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...

I use a DV3K dongle in a mac and both Buster and DVTools work with it.

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.
