Hi Hartmut,
Yes, it is very difficult. But you can make a personal estimation.
For example, i got no decode at YV7MAE although he did receive my
complete callsign in DFCW-90. But W4DEX got decodes although i am not
strong enough to leave my call in DFCW-10, i think ;-)
Compared to DFCW-90, WSPR-15 only needs 1/3 of the time and sends more
information (DK7FC JN49 30dBm). Anyway, from my point of view, if there
is no decode in WSPR but some clear traces giving a clear ID, DFCW-90
would win, regardless how long it takes and how much information is sent.
73, Stefan

What do you think, which QRSS mode is about as sensitive as WSPR-15,
from your subjective impression?
I would think it must be something arround DFCW-30. But we have to go on
with further tests. At least it is very promising!
Hi Stefan,
it's difficult to compare QRSS or DFCW with a digital mode. Last night
I only copied XGJ in QRSS60 mode. For a real comparison there is to
little activity.
