Hello all, Silly question: is anyone out there aware of whether there will be any available Codec2 or Yaesu digital support (From the team or from the community at large) for these formats on the UDR

Does anyone have ideas just how those of us living in the US near a PAVE/PAWS installation (e.g., most of California) are going to be able to operate this radio? I was really looking forward to ge

Would it be possible to expand the frequency range to 23 cm??? What tuner chip (rx and tx) do you use??? Why restricted to 1000 megs?? (there are now such nice wideband rx tx chips available from 3

We use the CMX991 IQ Transceiver which can operate from 100MHz to 1GHz, but that doesn't mean the whole radio design works over that range. The most likely next band will be 220MHz but as John says,

Is it possible to change the design and use a different chip?!? There are so nice chips that go 300-3 gig ... so then we would "loose" 2m (but that is not good for wideband data anyway) ... but we wo

Yes - of course! But..... I want a basic single band single feature (data!!!) radio yesterday! We can get more bands and more features with product updates.. Changes add months to the release cycle

Haa ha nice answer .. but does not help here I asked a serious question and also told a reason for changing ... If car manufacturer has made a new model ... and just before release it on the next c

Sigi, You asked what other group members think so I tell you what I think. Your design suggestions may very well be good ones. I don't know, but the UDRX is a commercial product for sale by what app

Ok ok ... I justwas thinking out loud ... Just thought with a different tuner chip it would be A LOT better And now in these sdr days ... it should be an easy task (yes not as easy as baking cakes .

As an R&D lab manager, I frequently have to address questions like this and weigh the answers. I'm not involved with the project itself, but from what I understand of where they're at in the process,

Turn your speakers on and listen to very weak signal CW running through the UDRX receiver. http://nwdigitalradio.com/receiver-sensitivity ------------------------------ John D. Hays K7VE PO Box 1223

Looking for testing resources / testing methods for installed UDRs at remote sites. - can the UDR be put into a loop back mode at the RF or modem stage remotely? - constellation display application of

Would it be possible/practical to set up GNUradio and a cheap SAT-TV SDR dongle as a quick, portable test set for the UDR's transmitter? It would be receive-only, of course, but having half the test

Use an rtl stick (dvbt usb stick) Then your favourite sr software (be it hdsdr, sdrharp or whatever) Route the audio to "soundmodem" and you can receive 1k2 or 9k6 packet Dg9bfc Sigi

Yes, it's the RTL stick that I was thinking about (I have a few of these already). I'm interested in the high speed modes that are now being developed, rather than the existing 1.2 and 9.6 kbps low sp

Brian, The remote location may or may not have internet access. The general concern for me is how do I prove that the initial installation is good - the grounding, cabling, connections etc - then a

Hi Adrian, We don't currently have any plans to offer the DV3000 in a USB or other factor. However, as Jonathan points out. The implementation of the dv3000d on the Raspberry Pi (and hopefully the
