Re: Yaesu Digital support / Codec2 support
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

Advance Notice: D-STAR DV
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.

We have a couple of inquiries in for custom filters, the NRE looks reasonable.

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.

Re: SAW Filter limitations
Also, I’m an “appliance operator” so I don’t understand the purpose of the

amateur radios in the 440 band don’t have.

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

Re: SAW Filter limitations
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.
