My observation - from the Western U.S. (Utah) is that JT9 is now almost 
nonexistent, effectively replaced by FST4-120 - I have only copied one 
or two stations using JT9 in the evenings, down from a dozen or more 
just a few weeks ago.

Monitoring both FST4W-120 and WSPR, I would guesstimate that about 20% 
of the number of stations are copied using FST4W-120, the remainder 
using WSPR.  I have simultaneously monitored other FST4W variants (300, 
900, 1800) on occasion and have not yet seen much there.  Again, this is 
from the perspective of my geography.

It's probably fair to say that more stations are still monitoring WSPR 
than FST4W-120.  At the moment, it doesn't appear that one can divine 
from the GUI at wsprnet (or at VK7JJ) whether someone is received via 
FST4W-120 or WSPR as the "spot type" coding does not (yet) appear 
differentiate between the two 120 second modes.
