[hpsdr] OzyII<> Metis

[Phil Harman]

Hi Maximo,

Well here are the main advantages:

-     No USB drivers needed, Metis will use the native Ethernet drivers of the OS being used
-     Very fast data transfer to/from the PC.  At 1Gigabit I've measured 936Mbps from Metis to the PC. Mind you  my Ethernet Switch         and        PC threw up their hands at that speed.  But in the future who knows how fast our PCs will be.
-    no USB drivers needed. 
-    Lots of room in the FPGA for interesting future developments.  We are only using about 18% of the 40,000 LEs in the FPGA.  This leaves plenty of room to add a soft core uP, multiple receivers  etc.
-    Assuming your home network is fast enough you can access your HPSDR radio from anywhere on the network - and via WiFi, wirelessly.
    At 192kHz sampling rate I can access Metis anywhere on my home network. 
-    no USB drivers needed. 
-   Enough spare room in the FPGA to do a complete transceiver e.g. all filtering, AGC, NR and demodulation so that the audio could be down to 8ksps.  That way you have a 'networked' transceiver that could be accessed remotely over the Internet. 

Oh, and did I mention, no USB drivers needed.

  Hi,

  Fantastic job Phil. 

  What main inprovings will offer the PowerSDR/Metis over Magister version?

  Thanks

  All, Here's the latest news regarding OzyII. I've completed testing the Alpha PCB and it checks out OK. I also have code for UDP/IP, DHCP, ping and Discovery working. We can also load a new image into the FPGA flash memory via the Ethernet connection and restart the board without needing to cycle the power. The board will also automatically detect the speed of the network it is connected to and select accordingly. There is also the facility to force the board to run at 100T in order to reduce power consumption if desired. I only have I2C to add and we will have a first release of the FPGA code ready. Bill, KD5TFD, has also built an Alpha PCB and has it working with Mercury and KISS Konsole. Bill is presently adding support for the board in PowerSDR(TM). We are currently preparing to produce a small run of Beta boards prior to production. These will have a few minor corrections and some re-positioning of components to make automated manufacturing and hand assembly easier. TAPR are also preparing for production and will make their own announcement regarding expressions of interest etc. shortly. We have decided not to call the board OzyII but rather 'Metis'. Since the board does not provide any SDR1000 interfacing it really does not follow on from the original Ozy name. Metis is the Greek goddess of wisdom and deep thought, but her name originally connoted "magical cunning" . It had been prophesied that Metis would bear extremely powerful children - which sounds promising for future projects! 73 Phil...VK6APH
