Vaughn, NW Digital Radio doesn't have any current project plans to implement either Fusion or Codec-2 on the UDRX-440. That being said, here are some thoughts for someone who would like to support

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

Jonathan Naylor, G4KLX -- developer of the open source D-STAR suite of software and contributor to the Linux AX.25 stack will be coming to Dayton Hamvention this year. He will be spending some time as

John, I have a question in connection with your comment, "Currently, the only DD network implementation is 128 kbps on 23 cm from Icom (ID-1 terminals, and RP-2D access point) and is half duplex (no

This is the vocoder chip and interface to the Pi or UDRX. This chip can vocode for APCO 25 Phase 2, but would require code for the P25 protocol, the modem, and RF chain. NW Digital Radio has no

We have changed the configuration of our DV3000 add-on board to use the same 26 pin header as the Raspberry Pi. The boards are working in the lab now and are headed off for application integration.

Is it possible to use two narrower filters switched for the high and low end of the band? Dave KA2OQZ

Thanks to all who contributed. We have a couple of inquiries in for custom filters, the NRE looks reasonable. In the mean time we'll move forward with the current design and plan on a UDRX-430 for

What about using a highpass with about 400 megs?!? Dg9bfc Sigi

The filter is required to suppress carrier feedthru on the TX side in the 350-380 range (Fc-IF). On the receive side it's a nice to have. We are working towards commercial certification, so some of

Also, I’m an “appliance operator” so I don’t understand the purpose of the filter. But I wonder why the radio would have a limitation that other amateur radios in the 440 band don’t have.

In Canada, band starts at 430mhz. Doug, ve7ept

Seems the same thing (or nearly) like the "hamnet" we have here in europe Tcpip based high speed network Dg9bfc Sigi

This view is probably heretical, but here goes. The US band plan is largely an accident of a lot of spectrum chasing a small use base, adopted in a very different time, assuming very different

In Northern California, packet and other data activity is in the 433, 434 and 438 range, with wideband channels in the upper of those two ranges. This is where we would intend to use the device.
