Re: USB touch screen

"John D. Hays" <john@...>
 

I would recommend powering it separately (either directly or through a USB hub), but the USB connection is there and its a matter of having a driver (Debian Linux).  A simple text based interface would put less tax on the processor, but I have run X-Windows over Ethernet to an external system without a problem.

There is also the option of the Web interface on WiFi to an iOS or Android device (phone or tablet), or possibly custom application written to do the same  over those devices.

The CPU on the radio is from the same manufacturer as this  http://www.mimomonitors.com/products/mimo-plug  -- though a different generation and slower (800 Mhz.) speed.

Hi Everybody,

I know it's early days and all... and I'm probably thinking way too much this early on in development...

I've been thinking of ways to control the UDR56K-4 without having a PC connected.

Would the processor in the radio be powerful enough to drive a USB connected touch screen... something like the Mimo Monitors products?

A very functional but simple control system could be quite easy to come up with that works on a small LCD screen.

Just an idea...

Processor architecture, gnuradio

Darren Long <darren.long@...>
 

Hi,

Can we get any ideas on what processor architecture, amount of RAM and
internal storage the device will have, please. Even the vaguest hints
are welcome at this stage. I'm wondering if gnuradio might find its way
in there somehow.

This is a quick screen shot of what the interface for winlink mail looks
like. There will be more detail in the upcoming app note on the website.

Let's walk thru it.

When I sit at my home station doing RMS mail I typically have a TNC
connected to the serial port/radio and the following windows open.

An email client
A console window to control connecting
A spreadsheet of local gateways containing frequency and other parameters

Now with the UDR 56K on the network I just open a browser window and point
to the IP Address.

The email client is on another tab. It's neomail, a free webmail program
but you could configure your regular email client to handle things.

The lower left frame is the control console. It's shell in a box and has
sshed into the UDR. On shipping software, this will default to display
only, but you can enable it in preferences and drive everything from the
command line.

The right frame is also shell in a box running ax25spy. I love this
feature. When I run airmail I can see the process but I can't see any other
packet traffic. This way I get both at the same time. Think of it as a
debug window.

And finally the upper left has a table which contains my local gateway
info. The difference here is that it actually controls the radio, so all I
have to do is click on a gateway and the frequency switching and connection
is automatic. I can even check one or more gateways and have the system
auto-connect to each of them in succesion.

You can export/import the table in csv format.

Lots more to come in the months ahead including multi-user login support.

Re: P25?

Here is the manual for the AMBE 3000 (the 3003 is the same but with three vocoder paths) -- http://www.dvsinc.com/manuals/AMBE-3000_manual.pdf

On page 84 see the footnotes.  

The marketing literature does claim IMBE compatibility http://www.dvsinc.com/products/usb_3k.htm  --  I don't find IMBE mentioned at all in the manual.

If it does support IMBE, that would be a bonus and a developer would be able to incorporate it as part of their stack.

Seeing that P25 Phase 2 is almost the same as DMR, how do they do it?! Phase 2 will do the same as DMR, use time slot 1 only on simplex. It will work, just only one time slot - one user at a time.

Keep in mind that P25 II TDMA is only capable of network repeater operation (read that "trunked"). Simplex is not supported on Phase II, as there is no way to accomplish the sync requirement for 2 subscriber sets in direct simplex mode, thus infrastructure is required.

Re: P25?

"William Stillwell - KI4SWY" <wkstill@...>
 

Well, if you don’t know how to “generate” data stream, decoding it is the first hurdle.

 

Ie, when “dstar” first came into light, ICOM didn’t freely publish the TCP/IP stack, it had to be “deciphered” and applications where written, application were used, to “gather the data” on how it worked.

 

DSD would be a great tool for understanding how the over the air protocol works for different modes, then one can work on building a transmit stream.

 

Before everyone was using GMSK modem chips for their “nodes”, but now people are using sound cards, and dsp chips doing it all in software.

 

You want to transmit P25? NXDN? DSTAR? And you want to do it now? Sorry to say, check out ebay.

 

I own 3 Dstar Radios (down from 5 and a repeater), and 2 NXDN radios and an NXDN repeater.

 

The cost of NXDN is way less then D-Star which is the sad part.

 

MTRTRBO is also looking very good price wise as well, (considering a “new” icom D-star Repeater w/Gateway server cost you 4K + (pc’s are not free, neither is the official icom gw software) if doing all “ICOM” labeled. MOTOTRBO Repeaters are around 2K ? I am not sure if it comes with the IP Option. Or how much more on top of the 2K.

 

There are a LOT of licensed operators who run scanners in their cars, and shacks, there great tools.
