Session text follows

20:34:26> *** You are now talking in channel: "OpenHPSDR"

21:02:58> "Bill - KD5TFD": woo hoo .. hearing below the noise floor!

21:06:08> "Bill - KD5TFD": 10c -- that the same vintage as a 15c 
or 16c?

21:07:06> "Mike - AA8K": I've got my slide rules. :)

21:07:09> "Bill - KD5TFD": neither my 15c, 16c, or 41cv still work

21:09:04> "Rick - VE3MM": yes the 10c is one of the voyager 
series, I believe the 15c is one of them

21:10:07> "Rick - VE3MM": I wonder if I can find my slide rules, 
I can't remember where I put them

21:10:40> "Bill - KD5TFD": Thankfully I never had to use Slide 
Rules, Punch Cards, or Tubes!

21:11:02> "Erik KM2G": I remember seeing tube testers in the 
front of Safeway, that's about as far as I've gotten.

21:11:45> "Rick - VE3MM": you are just a youngster Bill

21:11:51> "Bill - KD5TFD": I'd have to admit to remembering 
tubes in the TV as a young kid

21:12:19> "Erik KM2G": don't forget the big tube you were 
staring at, prob the last "tube" to be retired

21:12:26> "Bill - KD5TFD": ya

21:14:41> "Andy - KF5JLJ": here, but not getting out. Hot key 
ctrl-R not doing its thing...

21:15:08> "Erik KM2G": i'm using scroll lock these days

21:18:00> "Andy - KF5JLJ": Ahh, right ctrl, not ctrl-R :)

21:19:58> "Bill - KD5TFD": I'm @ 32 if anyone needs something tried

21:24:47> "Rick - VE3MM": we could use some propagation on 160 
right now!

21:30:08> "Bill - KD5TFD": varicode

21:31:54> "Erik KM2G": multiple beacons visible on the screen at 
once?

21:36:44> "Bill - KD5TFD": 100 khz over same time period/or same 
sweep rate?

21:41:15> "Bill - KD5TFD": you can align c#  .. just alloc what 
you need in C and pass the pointers ... you don't want C# gcing 
these thing typically

21:42:07> "Erik KM2G": the FFT library does provide memory 
allocation routines, look like they allocate too large a buffer 
and then return a rounded address.  couldn't get it working on c#

21:43:01> "Erik KM2G": For the code I've been in I wrote a 
library to call C# <-> C++ via naked C++ interfaces, in case 
that's useful for anyone to use

21:54:18> "Bill - KD5TFD":
