[GreenKeys] [Fwd: Re: Questions about some signals on the air.]

[Richard Knoppow]

    I've been successful in copying KSM, W1AW and a couple 
of QSOs using MMTTY. Feeding the sound card from the 500 ohm 
output of my R-388.  May switch to the 4 ohm output because 
its pretty high level. I just downloaded the current version 
of MMTTY, the one I've been using is a couple of years old. 
I did get it to work in the past using an SP-600-JX as the 
source. The R-388 works like a charm. Mine has been modified 
to have a product detector and slow AVC.

    I am pretty sure from comparisons to a couple of web 
sites that have recordings of various kinds of signals that 
what I heard is SITOR. There does not seem to be a freeware 
decoder for this and I am not quite curious enough to buy 
software for it.

    I am sure this is all very elementary to most on this 
list but its still a bit of a thrill to see the computer 
printing out the jingle bells.  Also, it will copy almost 
down to the noise level.  That is interesting because I have 
another program that will read CW but when the signals are 
fading and noisy I can easily out copy it by ear and I am 
not that good.

     My thanks to all of you who corresponded with me. My 
question may have been a bit silly but I get very curious 
about things.  Perhaps if I wasn't a nosy person to begin 
with I would never have gotten interested in Teletype.
