[Lowfer] " XR " D.C. USB XMTR Progress

[Andy - KU4XR]

Greetings all:

Moving at the incredible speed of the great slimey slug; minute
progress is being made. Unfortunately not on the actual Xmtr 
itself. Still procurring parts, robbing PC boards and such, and
trying to determine ( from my own way of thinking ) what will be
the easiest, and effective circuit for each stage of the Xmtr.

My most exciting part of the project so far, came over the 
weekend, when my wife managed to talk me into going to the local
flea market. I'm glad she did !! I bought a Toshiba Laptop for
$ 50.00, loaded with XP-PRO. It's a 366 MHz P-II with 194 Megs
of memory and a 7 GB HDD. I wasn't sure that system could handle
XP-PRO, but after hours of pushing it to the edge, it works fine.
I have loaded JASON, and MultiPSK to use for MFSK-16 & 8, and 
Spetrum Lab to use for S/MT Hellschrieber, and DFCW. I figured
that Spec Lab would be the program that would kill the machine,
but surprisingly, this little critter has performed exceptionally.
The program that has facinated me the most is S/MT Hell. Once I
began to figure out how to work the DigiMode terminal ( Wheeew ),
I started to see what Hellschrieber can do. I started experimenting
with the program parameters, which are user adjustable; and I 
have the program running the characters " X R  in a 3 Hz vetical
bandwidth. It takes 10 minutes to Xmit the sequence at the baud
rate I'm trying, .025 sym/sec. I have no idea what WPM, or QRSS
speed that would be, but using a 5 second scroll rate in SpecLab
QRSS 10 mode, and a 70 Hz window; the image is pristine, with 
no noise of course !! I can invision a great QRSS image 
generator here. With digimode and the S/MT Hell 7/5 font, I can 
set the vertical BW at 1 Hz, and a tone length of " Whatever ".
This will be the program that I will be experimenting with I'm
sure, quite alot.

As with any project; I just need to get that first component on
the board, and the adrenaline will take over from there.
