Philip,

I'm going to add External Clock as an unstuffed, untested, unsupported and consequently no-cost option.

I think it has merit and the elves seem to like it,

Are you asking for an external clock option to drive multiple UDRs from a common Clock?
Yes, precisely. If you can synchronize the phase of all the mixers and DACs and ADCs of a number of UDRs, each connected to a separate antenna, then you can do all sorts of neat spatial processing in software. What you have is an antenna array, but the phasing of the antennas is software controllable. You might call it MIMO, or beam forming, or spatial filtering, or field recording, depending on precisely what processing you are doing, and in what industry you are.

I'm not normally a fan of feature creep, but since this is something that requires hardware support, I thought it might be worth mentioning now. I imagine all the software that does the neat stuff can be implemented later, as long as the hardware has the necessary bolts, which is just phase coherence among multiple antennas.

Providing BER and RSSI are already in the plan, as well as socket access I/Q, modems, etc. -- The rest appears to be an application?

This is an open design radio, developers are free to experiment with various applications.  NW Digital Radio will provide the platform and a few applications, other applications will come from the community.

Re: Feature Creep

"John D. Hays" <john@...>
 

These type of signals are what Bryan is looking for -- I would just add that the UDR also runs in the 430 band, so they can have significant separation (in frequency domain) from repeater receivers (and transmitters).

E.g. if it is colocated on a site with a 444.9+ repeater [receiver at 449.9] and runs at 433.9, that is 16 mHz from the receiver and 11 mHz from the transmitter of the repeater.  2-3X the separation of the typical duplex pair.

[Please don't jump all over the use of particular frequencies, they are simply for illustration purposes.]

I see the TX inhibit input, but not the TX active output. Say I put
two of these at a site. How do I keep them from TXing at the same
time?

You use the colocated voice repeater example... maybe I want to
disable my repeater while the data radio is transmitting, not the
other way around :-)

What really excites me about a data radio like this is sampling the
receiver directly. I don't care if you implement any protocols before
selling it to me; I just want the SDR. I'm one of the guys who checked
the "Linux experimenter" box.

Will you add the receiver sampling specs to the datasheet?

Something simple like UDR1-band (UDR1-2, UDR1-4, UDR1-9, UDR1-12, etc) would both give room for future versions of the base UDR platform, as well as, define the supported band if a decision is made at some future date to support additional bands via different RF boards.

Have you ever thought about product names? It's kind of important.  A good name will identify a product in such a way that the observer is quick to understand the purpose of the product.

We have been thinking about the changes in the UDR56k-4 since it's first introduction.  At the time we had identified that the radio would be limited to a top data rate of 56 kbits.  This was in part due to the limitations of the modem/RF chip in our original design.  We have since changed our architecture into an I/Q Software Defined Modem (SDM) and will be delivering a modem that will likely exceed 100 kbits.

Steve, WA7PTM, contacted us and suggested we consider renaming the UDR56k-4 to reflect those changes and indicated we had a great resource --> the UniversalDigitalRadio Yahoo! Group.   We thought this was a great idea, thanks Steve.

We had been thinking about a model name change, but we thought Steve's suggestion was a great opportunity.

So, if you have a suggestion of what we should use for the name/model of the radio, here's your chance to change the destiny of all mankind :)

Please post your ideas.

Some guidelines:
  • We think it makes sense to keep UDR in the model number / name.
  • It should not infringe on any other trademark.
  • A Google search should not currently bring up an exact or very similar match
  • Keep it  short-ish.
  • Keep non-english meaning of the word(s) in mind (e.g. it shouldn't mean 'stinky eel' in Tongan)
  • Consider how it might relate to a family of products (e.g. a different band)

We will review your suggestions, and others developed in house. If there are several particularly good suggestions, we will create a survey where you can vote for your favorite.  

We reserve the right to use any or none of the suggestions.  

All suggestions become donated property of NW Digital Radio, without compensation. We will acknowledge the person or persons who came up with the chosen name.
