Cool. Is the source to these changes available anywhere?

Thanks,

Re: FT230 basic uart drives

Greetings,

The FT230X uses the default FTDI VID/PID, so it should be recognized with Windows Update.  If you don't have an Internet connection, or see the device under the "Other" devices tree in Device Manager, then run their EXE installer:


Unplug the ThumbDV, run the EXE, then plug the ThumbDV back in.  If you still have troubles after running the EXE, try right-clicking on the ThumbDV in the Device Manager, then select "Update Drivers"

thanks in advance


Re: Enough power to vocode in software?

myyahoo@...
 

I doubt that processing power has ever been the issue, we're talking about audio. However, even if the patent expires, reverse engineering the vocoder may not be trivial.

When it becomes legal, no one will be holding you back. Your task, should you accept it, is to

ENCODE/DECODE! :-)

Enough power to vocode in software?

randy@...
 

Hmmm...I wonder if the UDRX-440 would have enough processing power to encode and decode D-STAR in software?  The patent expires next year!


Open source software already exists...waiting for property rights enforcers to go away.

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

First make sure all other programs are closed including any apps. Check under device manager and serial ports to confirm which port you are using. If in doubt pull out the thumbDV while watching the com ports in device manage and you will see the thumb dv com port dissappear to confirm the right number. Use the magnifier program in windows to see the tiny text when choosing reflectors. Close the magnifier down when done with it because it seems to interfere with the thumbDV sound. I have been informed that pressing the space turns on the transmit button so you don't have to try to hit the tiny transmit button. I have had several crashes and a few lock ups. It's beta software. Otherwise it works pretty well. good luck

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,

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

You need to send a message to Fred to get the beta version.

Re: D-STAR Entry for $180...

Jim <prf10uk@...>
 

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

Is the range measured like a typical wifi dongle, 50-100',
depending on obstacles?

here is my digital dstar radio

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.
