PiDV or ThumbDV - for D-Star repeater?
Konrad Roeder -- WA4OSH <konrad.roeder@...>
I want to use UDRC-II to control a D-Star Repeater. Should I be using a PiDV hat, or a ThumbDV? What are the hardware and software implications?

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.

Re: ThumbDV with GnuRadio
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.

Does the GnuRadio block work with a PiDV hat as well?

FYI,

I currently use my ThumbDV and two Baofeng 888's on D_Star, audio reports are good and my pal who lives in the next street has used his IC706 for D_Star via my 888 while I am in control of my station. It's a useful learning project Regards, Ian..

Dave N2OA
Thank you.. Yeah that’s not pretty but it might be worth playing with.. It’s times like this that make me wish I had gotten into software J It would be a great product if someone could simplify the software and package all the pieces into one nice little box with a display to give any rig digital capability..

You can get there, but it is kind of ugly at this point UDRC <--> dstarrepeater <--> ircddbgateway <--> DummyRepeater <--> AMBEserver (with PiDV or ThumbDV)
Audio goes in and out of DummyRepeater.

Re: PiDV Connection to a FM Radio
The PiDV and ThumbDV are serial devices for encoding and decoding audio to and from AMBE. They do not connect to a radio or provide modulation or demodulation. The UDRC can provide the modem to talk to a radio. However, for a complete solution you would need both and software to handle the protocol, radio, and audio.

PiDV Connection to a FM Radio
Dave N2OA
I'm interested in a PiDV but want to know if it's capable of modulating and demodulating the signals off of the packet port on a FM rig? I can't seem to find any documention on the device to answer the question. Thank you, Dave KA2OQZ

Re: ThumbDv and Windows 10
George, This is probably a problem with WinDV, which is supported by DUTCH*Star -- NW Digital Radio manufactures the hardware, but software support comes from the authors. You can pull down ThumbTest.exe from https://nw-digital-radio.groups.io/g/ambe/files to test if your ThumbDV is communicating. If it passes this test, then the issue is not with the ThumbDV. What you may wish to try is to remove all references to the DUTCH*Star software from the Windows Registry then reinstall. John

ThumbDv and Windows 10
mi0ceo_geo@...
Hi all I am having a problem with the Dv Node for windows 1.5.8 preview3. When I start it up in windows 10 it runs for about 5 seconds then stops. Windows then puts up the report "WinDv not responding" I have to close the programme with task manager. I have tried the compatibility mode to run WinDv but still it stops after about 5-10 seconds. I can still see the call signs changing but no sound from my system. When I try to close the programme it plays 5 or 6 dings then windows again puts up the report "WinDv not responding". I have reloaded Windows with nothing but WinDv but still this problem persists. HELP Best George MI0CEO

Re: Thumbtest error
Andrew O'Brien
Gee, like the old days. I remember some old packet radio issues where the solution was "com 3 " rather than "3" after a Com prompt. i will give that a try. Thanks Andy K3UK

Re: Thumbtest error
Hi Andy, Make sure your ThumbDV is at COM3 (I am assuming that from the 3 you typed in), you can do this by observing Device Manager while plugging and unplugging. Then try COM3 as the input rather than simply '3'.

DV3000 one of the first boards and Pi 3
kb8pmy@...
So I have been running this on a raspberry pi one. That burned up a few weeks ago. I had to move the board to the pi 3. I have bluetooth turned off. It is raspbian headless. I can not get ambeserver to read the board on /dev/ttyAMA0. It says it can not find the start bit on the DV3K board. BUT the phyton script sends results back.
