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
