Re: FUSION support

wb1hbu@...
 

Hello,

I have Fusion decode working with the dsd program (rx only). I have the DVSI USB3000 and modified dsd to use it to decode D*, DMR, NXDN, and P25.

I am in the process of getting dsd to work on a Raspberry PI 2. I plan to use the DV3000.

I want to buy a thumbDV, but the paypal login button does not work on the order checkout page. Does NWDigitalRadio only accept credit cards and no direct paypal?

A couple of other hints.

Use the Quick Tune buttons (you may have to activate their display from the menu) for your favorite linking destinations, much easier to hit.

When in a pull-down menu (like the Repeater/Reflector list), the "left/right" arrow keys help navigate the list.

A little bluetooth keyboard/touchpad is handy.  http://smile.amazon.com/gp/product/B00FEZ3PCQ

Hi David,
My DV3000U is working great with my Samsung Notebook Windows 8 machine. I am having difficulty with my WinBook TW700, Windows 8.1 Tablet. I do have the Beta 1.5.8 software but have gotten errors trying it. Could you share with the group your settings? Not sure of comport, selections are 1 or 3. Tried both, no success. Other settings are difficult to see on the WinBook. Any way to increas the size of the text on display?
Thanks,

Re: preparing for UDRX delivery

bhhoyer@...
 

Hi Steve,

The UDRX works from 430 to 450 MHz so line A isn't a problem. Bandwidth is less than 5% so you could just make it resonant at 440 and be done.

Here in Western Washington the Band Plan lists:

430.8000 - 431.0000 Packet radio
439.8000 - 439.9750 Packet Radio
440.7000 - 440.7750 Packet repeater outputs
440.8000 - 440.9000 Packet simplex
441.0000 National Packet simplex frequency
445.7000 - 445.7750 Packet repeater inputs

Which suggests centering at ~ 438

Of course if you choose to do D-STAR you could be pretty much on any analog voice channel or even one of the splinter channels between analog.

I wouldn't over think it too much,
Bryan K7UDR


preparing for UDRX delivery

Steve <yahoo-udr@...>
 

I'm thinking of initially using a J-Pole antenna for the UDRX, so want to construct it for the right part of the band. Has anyone thought about where in the 70cm band UDRX communications would best fit (both North and South of Line A) so as to not disrupt other licensed users of the spectrum?

Thanks,
Steve

It will only be as good range as the wifi on your tablet , it's not a radio in that sense.....

David Warden <dwarden3@...>
 

All digital dstar "radio"! This was $180 to put together.

thumbDV plus one Winbook 7" tablet running Windows 8.1. I'm using WinDV 1.5.8 preview 1.

I was using Ambe server, dummy repeater, and ircddbgateway before I got Windv.

Has been working well so far. battery life on Winbook is somewhat limited, so I just leave it plugged in while monitoring reflectors.

Re: How fast are decodes

"John D. Hays" <john@...>
 

I don't have any data on speed of actual decode time.  These chips are usually used to handle one stream in slightly delayed real-time (e.g. they can keep up but there is a small amount of compute delay between input and output).  Also the ThumbDV is tied to a 230.4 kbps transfer rate.  I would plan on one ThumbDV per stream.

The DV3000 (GPIO version) can use trace-cut / jumper to increase the bps on the serial interface, but anything along that path is pure experimentation.

Ah! That is good to know about IMBE vs AMBE. Right now I am using OP25 and it doesnt look like it is too tough to dump the packets at the right level.

How much faster than real time can it decode a packet? How long would it take to decode 10 seconds of audio? Would it be 10 seconds? I am trying to figure out how many recordings I could queue up and have it keep pace.

Re: How fast are decodes

"John D. Hays" <john@...>
 

Luke,

Richard is correct, the AMBE3000F chip in the ThumbDV is a single stream vocoder.  It only vocodes the audio stream, not the P25 (or other transport) protocol.

Since it is a USB device, you can plug in several which will each appear on their own "COM" or "tty" device to the OS.   Plug in as many as your computer / OS / USB busses can handle for parallelism. Each appears as a 230.4 kbps serial device.

Your software will need to remove the AMBE stream from the P25 protocol (for each channel), buffer it into packets and send it to the ThumbDV, for each packet of AMBE it will return a packet of PCM encoded audio back (and visa-versa).

It will not decode IMBE (P25 Phase 1), only P25 Phase 2.

Given the price of dongles, you might want to try a hybrid approach, and offload a stream or two and do the others in software?

How fast are decodes

Luke Berndt <lukekb@...>
 

I have a system setup to record a trunked radio system. At times I am recording 3-4 P25 voice channels. I am doing the decode in software but it needs a lot of CPU. I am interested in using the USB dongle. I was thinking of capturing the raw streams and then passing them through the dongle. How much faster than real time is the decoder? How many simultaneous recordings could I have going on and still keep up? Would it changes with p25 phase 2?

And I will thank you for staying the course and providing a great radio at a reasonable price.  Don't be tempted to make a radio that is all things to all people, and priced accordingly. 

I intend to vote using my decision to buy...I'm sure Michael will exercise his prerogative too.

After we deliver the hundreds of units to which we are committed, we will evaluate the market and determine how to best allocate our resources. Your input is just one of many requests we have had for the future of the UDR and it will be given our sincere consideration.

Re: RF access point application confirmation

Robert Copelan <rcopelan@...>
 

There are some pretty small companies,  some people even not a company but working on their own that are delving into the bleeding edge hardware and software.  The large number of resources of a company like Motorola, Icom, Yaesu or Kenwood are simply not available to them. 

The really leading stuff relatively open hardware like the DV3000 devices, DVMega boards, DVRPTR boards, GMSK modems like Moencomm's board are out there for us to take and use.  There is NO offer from the people that produce them that there will be total turnkey software or solutions developed for specific use cases that each of us might have.  Result is that we get some darn good hardware at reasonable prices.    The  UDRX, the upcoming Moencomm board and  ConnectSystems'  CS-7000 will be welcome additions to that list.   

Yes, not everyone is a programmer and not everyone's requirements will be met.  One thing is for sure:  We are moving at an ever increasing speed in hardware and software development these days (not just in amateur radio).   If a requirement isn't met today then it might be in the future and maybe by a source that hasn't even surfaced so far.    

I'm thankful we have these folks doing things even if it keeps my wife wondering what gadget I'll get next and why my wallet stays empty.  ;-)

If the UDRX doesn't do what you want, what are you going to do to move it forward?
