Session text follows


20:40:21> *** You are now talking in channel: "OpenHPSDR"

21:03:43> "Bill - KD5TFD": woo hoo on the keyer phil

21:03:56> "Ken N9VV": Good on ya' Mate'

21:04:40> "Bill - KD5TFD": surely there must be some latency ... 
maybe a micro sec or two for gate propagation?!?!

21:04:59> "Ken N9VV": T/R latency to be worked on

21:05:28> "Bill - KD5TFD": just a physics thing ... got to take 
some time for the key close to propagate to the fpga ..

21:06:24> "Phil-VK6PH": latency is 33uS

21:06:39> "Bill - KD5TFD": tjat

21:07:10> "Bill - KD5TFD": that's pretty quick

21:07:23> "Greg ZL3IX": Any plans to put the new CW into Penny, 
Phil?

21:07:39> "John - AJ6BC": Hi! Hi!

21:07:55> "Phil-VK6PH": Yes, a little more difficult but I do 
intend to do that

21:08:04> "Greg ZL3IX": Great!

21:08:35> "John - AJ6BC": Scotty - just sent you the block 
diagram for Themis. - So, you should have Khronos and Themis in 
your inbox now.

21:12:58> "Scotty - WA2DFI": Thanks, John, got them!  Is there 
any way you can export a JPG?

21:13:19> "John - AJ6BC": Should be able to - let me try that - 
  back in a few.

21:14:53> "Bill - KD5TFD": wow

21:18:46> "Dave WW2R":

21:22:25> "John - AJ6BC": Scotty - just sent the JPG's.

21:23:47> "Bill - KD5TFD": Toasty

21:29:39> "John - AJ6BC": Guys, not to thrown a curve ball in 
this - but in the past week I have had some people ask about 
PXIe and 'Blade' computer backplanes - if we could go from 
'Atlas' to one of these- we can also get more traction in the 
industry I think.

21:29:58> "John - AJ6BC": We can design our own to keep costs 
down - I would suggest PXIe at this point.

21:30:05> "John - AJ6BC": *throw

21:33:02> "John - AJ6BC": NI says it is down now.

21:33:34> "Bill - KD5TFD": only $8799 for the chassis?!?

21:33:37> "John - AJ6BC": PXIE Hybrid is what we can think about.

21:33:47> "John - AJ6BC": Yeah - why we would need to roll our own.

21:33:52> "Bill - KD5TFD": ya

21:34:05> "John - AJ6BC": Same spec as PCIe.  Getting popular.

21:34:10> "Bill - KD5TFD": or find the cheap Asian knock offs

21:34:49> "John - AJ6BC": Ah, sure they are out there.  Don't 
know of any off the top of my head.

21:35:06> "Bill - KD5TFD": all new to me

21:35:09> "John - AJ6BC": Brand 'X' they talk about on that site.

21:36:50> "Ken N9VV": Note: July 2007 N8VB had SERDES (Optical) 
link to PCI bus

21:37:07> "Ken N9VV": "2.5 Gbps Serial Link:
The other end of the 2.5 Gbps interface will be a PCI and PCI 
Express board for the PC. This interface board will have a 
matching TI TLK2701 SERDES, a CYCLONE II EP3C25, a TI CODEC, and 
a PLX PCI or PCIe-to-local bus interface chip. The two boards 
can be connected by Cat6 copper or optical fiber through the SFP 
module interface."

21:37:36> "Ken N9VV": N8VB finished those interfaces and they 
worked quite well

21:43:24> "John - AJ6BC": Thanks - Phil - any opinions on the 
backplane?

21:44:16> "Phil-VK6PH": Need to review more before I comment

21:57:41> "John - AJ6BC": Election?

21:58:50> "Warren - NR0V": 73 all -- going to check on the
