UDR Progress Report

Hello All,

Basil delivered  the IQ ADC/DAC driver earlier this month and Dennis has an initial port of the modem completed, so we are moving into RF characterization. Once the transmit chain has been checked out, I will be working on the PA, RX/TX switch and thermal characterization while Dennis proceeds with the receive chain.

I have started layout on prototype II. I anticipate a third spin on the prototype before moving to pilot production in China.

We will not accept orders until I have fully functional prototypes in hand and then there is a 8-12 week production cycle.

Best case is orders this year for delivery in late Q1.

The initial deliverable includes:

  • 9600 MSK and 4800 GMSK Modems
  • Support for AX.25 and D-STAR DV
  • Winlink Client/Server
  • APRS Tracker/IGate
  • D-STAR IrcDDB Gateway
  • Hi-Speed Test Mode*

D-STAR Voice using the AMBE add-on card will be released after initial shipments are complete.

*We are not implementing legacy 56k support as there is little installed equipment and our engineering efforts are better spent on faster modes with FEC. The Hi-Speed Test will allow us to prove out our hardware and start gathering channel characterization data.

Full support for Hi-Speed TCP/IP and D-STAR DD will be a free Software Update in Q3 2014.

Thanks to all of you for your patience and support,
Bryan Hoyer, K7UDR
