[AA8K73 GMail]

NOTE:  next week's TeamSpeak session will be starting one hour 
earlier, due to the great effort in most of the U.S.A. to "save" 
daylight.


The 8/March TeamSpeak mp3 (62 minutes) 64 kbps is available at:

or

The audio in this session was leveled with Levelator.


This session:  status reports, issues, Pure Signal realistic 
effect limit, stress testing the 300,000 Logical Element array 
with many receivers to determine power consumption, new CW keyer 
design and amplifier switching.


Session text follows


20:40:36> *** You are now talking in channel: "OpenHPSDR"

21:13:07> "Greg ZL3IX": Will the new CW be QSK ready Phil?

21:13:53> "Phil-VK6PH": Subject to delays in the Rx path DSP code

21:18:38> "Greg ZL3IX": True about keying features.  I use my 
own external keyer anyway

21:19:58> "Ken N9VV": Greg, I can't hear my WinKeyUSB (K1EL) 
sidetone with headphones on to listen to the rig.  These changes 
sound like they will open a whole new SDR world to CW ops  I am 
very encouraged.

21:21:13> "Greg ZL3IX": I also use K1EL, but I use the PowerSDR 
sidetone

21:24:43> "John - AJ6BC": Scotty - I just reviewed your:

21:26:08> "Scotty WA2DFI": what did you think?

21:26:13> "John - AJ6BC": Where are the HPSDR-'Stick' schematics?

21:26:19> "John - AJ6BC": Pretty good.

21:27:24> "Bill - KD5TFD": love those empirically determined 
constants

21:34:02> "John - AJ6BC": Guys - can you post the URL to the paper?

21:43:42> "Bill - KD5TFD": We forgot to mention ... US changes 
clocks this weekend

21:44:28> "Dave - KV0S": Yes I was going to mention that as 
well. so we move to 1:00 UTC

21:44:31> "Bill - KD5TFD": We're moving forward an hour, so 
folks not changing time TS will be an hour earlier (I think)

21:46:24> "John - AJ6BC": Dave L. - is this a good e-mail for 
you:  kv0s.dave at gmail.com ?

21:48:44> "Dave - KV0S": Yes that address is good.

21:49:07> "John - AJ6BC": Did you get my last two e-mails?  One 
sent end of Jan, one sent today?

21:50:44> "John - AJ6BC": Great news Phil!

21:50:56> "Ken N9VV": Vision in both my eyes with "IOL" is 
better than all my adult life!

21:52:14> "Dave - KV0S": John,  Yes I did but I have a little 
busy at work,  I usually work on Radio mostly on weekends, Sorry

21:52:16> "Ken N9VV": N1EU says delay is only a "problem" if you 
want SHARP DSP FILTERS

21:52:52> "Bill - KD5TFD": sharper the filter, longer the delay 
.... basic dsp/physics

21:53:05> "John - AJ6BC": Dave - it is OK - just wondering if 
you got the e-mail.  Glad it made it OK.  No rush but let me know.

21:54:32> "Ken N9VV": 21:59:50> "Ken N9VV": Real World Ten-Tec 
Jupiter model #538 REAL QSK rig for sale <n9vv at wowway.com>

22:00:49> "Dave - KV0S": I need to go, talk to you next week.73

22:00:52> "Ken N9VV": K1EL has "Paddle sensitivity" to overcome 
bounce and problems with Begali paddles

22:00:55> "Warren - NR0V": 73 --- dinner time

22:01:03> "Scotty WA2DFI": 73 warren

22:05:49> "Rick - VE3MM": 73 all

22:05:55> "John - AJ6BC": 73's.

22:06:59> "John - AJ6BC": That is really interesting Ken.

22:08:16> "Ken N9VV": Doesn't it take a MOSFET/LDMOS PA take 
some ms to get to full power?

22:09:45> "Ken N9VV": Little pezio buzzer to generate sidetone

22:11:15> "Ken N9VV": Ah - FB FB, thanks Phil
