Another general topic we should consider is how messages of various types and handled in digital/packet ham radio. We need a great deal more interoperability and integration in our otherwise powerful

Tom, Are you still located in the Seattle area? There is a large number of us in the greater Seattle area that have signed up to buy. 73, Kenny, KU7M

Hi Tom, If you are still in Gig Harbor, the Puget Sound has the highest concentrations of pre-orders. The map will be forthcoming soon, just working through a technical blocker. The map will not be

How long until the UDR Network map is up? I'd really like to know if there are other pre-orders in my area. I suspect there are quite a few people waiting to place their pre-order until they see

One thing I have never been clear on. Will this radio do RF based D-star voice mode? I know the D-star is an option like the UT-118 is for my IC-2200H. Once added can I use the computer headset for

As noted, the UDR is not full duplex. However, it would be possible to create a repeater by attaching a node adapter, dvrptr, or similar device between the UDR and a separate receiver. G4KLX's

I stand corrected. -- Respectfully, W. Marshall Denny II Software Development Engineer 206 734 9242 cell For if you altogether hold your peace at this time, then shall relief and deliverance arise

Really, If the UDR can operate full duplex. Then with some software, it could be a Dstar repeater in a box, nice. -- Respectfully, W. Marshall Denny II Software Development Engineer 206 734 9242

The UDR56K-4 is not full duplex. The purpose of the independent port kit, is to support installation at hi-rf sites where filters or isolators are required. The vast majority of customers will not

PROS: Full-Duplex No T/R Switch time issues Con: External T/R Switch, less self contained

con: need to supply your own pinswitch or filter to use a single antenna and coax, pro: ability to work full duplex. -- 73 Andre PE1RDW

I would like to find the pros and cons on having the Independent Rx, Tx Ports: ? Gavin VA3XRR

Steve, WB4IZC, asks: "What will be the TX duty cycle of the new UDR56K-4? Does this figure very between tx output powers?" The UDR56K has a substantial heat-sink designed for high duty cycle

FEC can provide significant improvements in overall data speeds in a mobile environment - but it is only one factor that needs to be considered. Modulation mode, symbol rate, interleaving etc also

I will have a look at FX.25. But, with the flexibility that the UDR will give us. Lets keep all good ideas on the table until we have a good reason to remove it. The potential of FEC is not will

The problem with FX.25 is that in order to be backwards compatible they bundle the FEC bits at the end of the packet. As no-one to my knowledge has actually deployed FX25, I prefer a clean sheet

That sounds very much like the FX.25 protocol: http://en.wikipedia.org/wiki/FX.25_Forward_Error_Correction It's even backwards compatable with plain old non-FEC AX.25 equipment. Though it does not
