John,

What power connector is planned for this; many EmComm units have standardized on the Anderson Power Pole, so it would be nice to have this as an option at least.

The units at Dayton were engineering prototypes. They show the right form

RF board to the Computer board, the SMA connectors will be replaced by a
single N connector, and the power connector will be installed.)

Some folks took pictures at Dayton, but no "official" photograph is
available. The illustration here

Does anyone have any actual pics of the new Digitail radio, that made it
debut at Dayton.

I think it from DW DIGITAL RADIO.

Hi Matthew,

It was good to meet you in person at Dayton.

The chassis connector will be a solid, high reliability connector. I don't have the model number handy, but it has leads for you to create your own mating interface like Anderson Power Poles.

Heard on the street

Steve <stevewa206@...>
 

Hi all,
I was with a small group of hams this weekend talking about the radio. One of them mentioned that he was not interested in the radio because he did not know Linux. I think there might be some marketing issues here. I do believe that there will be web pages for set up ans applications so a user does not have to use the Linux command line? Or is that later? 

Tons of non Linux users out there.

Re: Heard on the street

A user would normally access radio functions either via a Web Browser or custom application running on their own computer under its operating system.

Many devices people use every day run a form of Linux and the user never knows. IOS on the iPhone/iPad are based on a Mach kernel (like Linux) and Android is a Linux based OS. Most home Internet routers are also Linux based.

If one is going to write new protocols or applications, then they will probably need some level of Linux knowledge, though one could cross compile and file copy for some applications.

Full Duplex?

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

One thing I forgot to ask at Hamvention, is it capable of full duplex?

Re: Heard on the street

Several years ago, I was working as a CTO of a government organization. We were low on funds to purchase public access PCs that we put in the libraries for people to use, but had a room full of discarded desktop computers from a recent replacement project. We had no extra seats of Microsoft products for these computers.

We put a flavor of Linux and OpenOffice on those PCs, deployed them to 4 different libraries and had zero complaints.

After a bit of tweaking, Linux looked so much like Windoze that the casual user didn't notice a serious difference. Five years later, that practice is still in use - when used desktop PC's are replaced, they go to the libraries and to the jail for use, running Linux, costing the local government nothing. 

There is nothing to worry about. Linux is generally more stable that Windows XP and at least as easy to use. This is nothing to fret about.

Re: Full Duplex?

The model shown at Dayton is half-duplex only.  Some duplex applications will be possible using external hardware plus software, we'll have some application notes in the future.

I read a phrase of nearly exactly that wording in several places on the website...  If people are unwilling to research a product before purchasing it, maybe the product in question isn't right for them.  Just MY opinion.

Re: New file uploaded to UniversalDigitalRadio

"Karen Tadevosyan, RA3APW" <ra3apw@...>
 

Hi John,

well, UDR56K - sounds good and promising.

Can I have few questions:

- RF TX power 25W is for 100% TX cycle? No degradation or switching to low RF power level?
- any additional cooling systems for 25W RF power and 100% cycle?
- what is RX/TX time (TX delay)? Electronic or mechanical RX/TX switching?
- RX: conventional or SDR (I/Q)?
- bandwidth of I/F filters for different speed (switching filters)? Type of filters?
- two points modulation (VCO + VC-TCXO)?
- RX multisignal selectivity?
- direct interface to TRX?
- availability of description of internal interfaces?
- kit availability?
- do you plan to demonstrate any concept of UDR56K in Friedrichafen, Germany in June 22-24?

Good luck with the UDR56K project!

Karen, RA3APW

Group populated quickly :-)

"perryc" <canoeman@...>
 

Wow this group populated quickly, 93 members in 2 days.
This bodes well for this radio. Looking forward to seeing this in production.
I would like to dump my aging dvr2-2 data radios, and kpc3's on my hill top APRS digI, and make it an IGATE in one swoop.
And have a dedicated D-STAR rig at home and in the field ops.
Pics would be great, even if just production pics of beta.
Something to keep up interest, well we wait....?

I think the Linux OS is a great platform for development, if it had a Windows OS, I'm sure the price would be very high and limit developers somewhat.

No 2m but still an APRS igate?

Sander Pool <sander_pool@...>
 

Hi,

the radio looks interesting but without a 2m radio how could it reasonably be an APRS igate? I realize you can run APRS on many frequencies but it's not much use running an igate when no one is using your frequency. I'm asking because APRS is listed on the flyer. Actually it seems 2m is a more popular packet frequency for winlink2k as well but at least in that case there is no agreed upon frequency so you can run one on 70cm.

Thanks,

Sander W1SOP


Codec2

"nikropht" <nikropht@...>
 

I wanted to let this group know about the progress on Codec2. Codec2 is a fully open source DV codec being developed as a replacement for AMBE2000 see http://www.codec2.org/ for details.

Re: No 2m but still an APRS igate?

"kc5zrq" <kc5zrq@...>
 

Really? VHF? I operate APRS and RMS Packet using UHF at 9600 baud. It works so much better than 1200 baud packet on VHF. The noise floor on UHF is usually lower. A typical ham dual-band antenna has higher gain on UHF than VHF. The bandwidth of 9600 baud AX.25 is more narrow than 1200 baud. There is lots more unused spectrum on UHF than VHF. I want UHF!

The main reason I'd buy one of these radios today is to use as a home
digipeater and iGate for our 96UHF alternate APRS network. UHF and
9600 is plug and play with the Kenwood mobiles but doing 9k6 is a pain
with any other setup.

All you need to make an APRS alt channel is one (preferably two) IGate
on any other frequency. The hard part is getting folks to actually
make use of it. (9k6 is a disadvantage here too but that's another
discussion...)

Re: No 2m but still an APRS igate?

Sander Pool <sander_pool@...>
 


Right, if you have a local userbase that runs APRS on 70cm then this would be a great radio. It could even be an advantage that no one 'in the know' will be pinging your igate with 144.390 packets. But as a general purpose APRS igate it would not be very useful.

http://info.aprs.net/index.php?title=Frequencies

To be clear, I have nothing against UHF or any other frequency, of course. Clearly there are advantages to running 9600 baud packet over UHF. I was questioning the use of APRS in the flyer. I suppose anyone with the knowledge to set up a linux based APRS igate would not be confused and quickly see that it is not usable on the most often used frequencies.

Not just as a development environment; The stability of Linux makes it ideal for consumer grade products as well, which is why so many consumer grade products (like phones and TVs and routers and firewalls and... etc) use  it.
