<DIV><FONT face=Arial>Hi Maximo,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Well here are the main advantages:</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>- No USB drivers needed, Metis will use
the native Ethernet drivers of the OS being used</FONT></DIV>
<DIV><FONT face=Arial>- 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.</FONT></DIV>
<DIV><FONT face=Arial>- no USB drivers needed. </FONT></DIV>
<DIV><FONT face=Arial>- 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.</FONT></DIV>
<DIV><FONT face=Arial>- Assuming your home network is fast
enough you can access your HPSDR radio from anywhere on the network - and via
WiFi, wirelessly.</FONT></DIV>
<DIV><FONT face=Arial> At 192kHz sampling rate I can access
Metis anywhere on my home network. </FONT></DIV>
<DIV><FONT face=Arial>- no USB drivers
needed. </FONT></DIV>
<DIV><FONT face=Arial>- 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. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Oh, and did I mention, no USB drivers needed.</FONT></DIV>

Hi,<BR><BR>Fantastic job Phil. <BR><BR>What main inprovings will offer the

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
