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: 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.

Is that software available has to be the next question. 😄 Dave

Re: PiDV Connection to a FM Radio
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.

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..

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..

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

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.

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.

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: 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.

PiDV or ThumbDV - for D-Star repeater?
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: 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: 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 Bryan K7UDR

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...

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
