I have been qrv HSCW for a while now, here are a few links
for more information. I use Cool Edit '96 for tx and rx. Here is what a
ping looks like with Cool Edit.
You can see "0gu s2 s2 kb0v" It's about .6 seconds long that's
from a sked with KØGU
This picture shows how AGC can make the signal stand out better with CoolEdit96

Correctly identify the callsigns in Whoisit.wav and get your name here!
The signal is almost out of the receiver passband, and not very strong, so it was one of the hardest pings I have ever decoded.
Just email me (see the bottom of the page) the correct answer and get my warmest personal regards as well as you name here! (WOW!!)
