Steve:
Being you are the VP of engineering...any insights to the shipping date
for the first batch of 6x00 radios?
Unfortunately, I'm on the second batch likely to ship after the first of
the year..

In the FLEX-6000, the DSP is done in the radio. If you pull up a
panadapter, place a slice receiver on the display and start listening to
the audio, the computer is not involved in anything except commanding the
radio and displaying the panadapter. You can turn off your computing and
audio will continue playing out the radio. A big DPC hit might make your
display stutter, but it will not affect your audio.

But shouldn't DPCs be much less an issue if at all with the 6000 series?

Absolutely! Windows is pretty good about handling more than 1 ethernet
device.
Word of warning, get an Intel card. By all means, do not get a card using
an Atheros chipset (yes, this will prompt hundreds of people swearing by
the excellent performance of their Atheros ethernet service on their
motherboard, but just take it from some who works on a lot of people's
computers that Atheros has the worst drivers out there.
Second word of warning: Realtek chipsets can be okay but their drivers
seem to flip-flop on generating DPCs. For instance the very latest set of
drivers from Realtek causes DPC spikes in the 300-600 us range. Just
falling back to the previous version restores its DPC good behavior.
I will bet on Intel ethernet drivers more than any other brand I have
supported/installed. You can get a good card for 30-40 bucks, why take
chances!

Can ine simply put a second Ethernet card in the computer?

Subject: Re: [FlexEdge] Computer requirements for 6000 series
Michael is correct. SmartSDR-Win will put more stress on your graphics
subsystem than PowerSDR, but don't don't go out and buy high-end 3D
graphics card. Most recent GPUs will have enough horsepower.
We are putting together the Quick Start Guide for the networking
requirements. I recommend that you connect the FLEX-6x00 to a switched
100 Mb/s Ethernet port for best performance, your PC should also be
connected that way as well. Most Internet routers, including
thewireless ones, have switched Ethernet ports on them. Do be careful
of very low-cost 10/100/1000 consumer Ethernet switches as they may
radiate RFI when an Ethernet cable is connected to them, in which case
you may need some mix 43 ferrite beads on the Ethernet cables to cut
down on RF emissions from the switch itself.
Speaking of Ethernet cables, CAT 5e or better is recommended. Do not
use shielded twisted pair (STP) cables as this will create ground loops
unless you cut off one end of the STP cable to break the shield,
replace
it with a plastic RJ45 connector and connected the shielded end to a
well grounded FLEX-6000.
How much client to radio (server) network bandwidth you will need will
be dependent on the number of panadapters / active slices and the
nature
of the streamed audio for said slices. GigE will not be a
requirementand
you might be able to use 10BaseT with an 8-slice display, but you will
be getting close to maxing out that bandwidth. One caution with
wireless client connections; the bandwidth quoted for your wireless
connection is the theoretical maximum and you will never achieve those
throughput speeds in real world applications. Also the bandwidth quoted
accounts for both the RX and TX paths, so you will need to divide your
theoretical maximum bandwidth in half to get an idea of the actual
bandwidth you are working with.

Does anyone know if this is correct?
