The SignaLink supported software page has a nice summary of software
decoders see http://www.tigertronics.com/sl_soft.htm
If "universal" means automatic selection of the correct decoding mode,
that would be a challenge!

I have not been on the air for a year or so, but decided to get back
on. I was listening to a DX station around 1833 when a digimode
station up roughly around 1837 came on with a LSB "spurious" signal on
1833. His signal was a series of slowly changing stepped tones. I
don't know what mode that was. His unwanted sideband suppression was
about 40 dB, but that was not nearly enough. He was 15 dB out of noise
with his unwanted sideband.
Does anyone know of a universal software to decode signals? Since the
FCC does not require a CW ID, I think that is the only way to identify
stations.
I assume:
1.) Operators are unlikely to accept they have a problem if they are
getting good reports on the intentional signal
2.) Some rigs just should not be used for digimodes (this was a
sideband suppression issue)
3.) Those who unwisely placed digimode subbands next to popular weak
signal areas, especially when sideband selection produces a supurious
that falls in weak signal areas, are unlikely to rethink the poor
placement or poor advice on selecting sidebands
4.) With a little work to convince them, most digital ops with radio
problems would avoid operating
