OT - Looking for the site with the SOUNDS of various digital comms...

[Tom Hammond-2]

A while back, maybe a year or so ago, someone had found a site which offered
audio snippets from various forms of digital communications (PSK31, PACKET,
MFSK, SLOW SCAN, etc.).  There are several digital 'sounds' I'm hearing
regularly, but I can't tell what they are because I have no frame of
reference
for some of the newer modes.

Can anyone provide the link to that web site?

Thanks,

73,

The FLdigi site has a nice set of waterfall displays and soundclips.

Another good way to hear what different modes sound like is to take  
your favorite sound card based digital mode program, direct the output  
of the program to the computer speakers instead of to the sound card  
that is connected to the rig (turn the rig off so there is no PTT  
action, just in case). And then select a mode and "transmit" away.  
You should hear what a particular mode sounds like on your speakers.

You can even use two computers to talk through an audio path --  
speakers of one computer to microphone of second computer -- and makes  
a convenient way of demonstrating digital modes to a ham club if you  
have two laptops that are equipped with built in microphones. (But be  
aware of multipath that because of the the low speed of sound in a  
small room, the duration of the multipaths off the walls of the room  
are about the same as the baud rate of transmission).  This is  
basically Einstein's model of telegraphy, but without the "cat." :-)
