Simple to find - you get some of the free software that has a "waterfall"
graph that shows the bandwidth from 100 hz to 3Khz and look for the sound
"trails" - they are very distinctive - you can have multiple signals in a 3
Khz bandwidth - easy to use - look for psk31 software - most is free and
works thru your soundcard.

PSK31 is more of a conversational mode like CW or RTTY. I'm
not sure it has any error correcting/retry at all. It just has a very
good ability to pick a signal out of the noise. I wonder how you
QSO with a station you can't hear? How do you find it?

would like to know how PSK31 compares CLOVER for weak signal digital
modes? 73 Doug K7ABX


Can't say. I never ran Clover because it was overpriced and
proprietary.
I've never been crazy about overpriced and proprietary.

One fault of PSK31 is its NOT an error-checking mode grinding the
transmitter on and off looking for an ACK response. It's more like FEC,
but I don't know what it's FEC capabilities are to correct errors. I
think
Clover is also error correcting by grinding away until the data packet
gets
a successful ACK, isn't it? Not in the same league.

PSK31 simply copies when I can't even hear the station its copying in
all
the noise. It's not meant for data transfer, just text between stations
in
an open system. There is no "connected" mode, like packet or SITOR or
PACTOR or such.
