Hi Dan
Go for the Digital Modes For Occassions by ZL1BPU, I have just
received this book and can't put it down. I have the other book as

Regarding matching the RTTY tones... matching a tone
is difficult for some people and easy for others.
For example, some people sing off key! Were you good
at matching the note of the pitch pipe in music
class? :-)

You said some RTTY signals did not sound the same as yours. I heard this

comments about matching the RTTY tones, his and mine. A few times
over the weekend I did note that my tones did not sound as musical as
the tones I was decoding. Looks like I need more practice with RTTY FSK.

started pushing the envelope (or should I say, squeezing the envelope) with
those 170 Hz tones... things were much simpler in those good ole days... your

It once was very easy to copy RTTY when *everyone* used
2125 and 2295 Hz tones. Then came the 200 Hz shift TNC's
and now you have sound cards and people that are up side
down with their tones. And please don't get me started on
no CR/LF after 70 or charters.
Andy,
I use only AFSK lately. I find it easier to net, just click on the
waterfall and there you go.
One asset of soundcard generated keying is that usually the tones are a
bit softer, due to the use of phase continuous keying, which may not
be the case with IF generated FSK inside the
