You can still do eme on CW, just it will take a bigger antenna array
and 1000w to be heard. JT-65 enables a station with a couple 10
element yagis or one longer yagi and 150w the ability to do eme on
2m. That is a huge attraction.
One takes about $5,000 and the other $500-800. You see the 10-dB
advantage applies to the cost as well! ;-)
CW is still prevalent on eme at 1296 and above. I still hear plenty
of CW around 14.020. It is the main mode used on LF and MW. but
digital modes are demonstrating they are superior in weak-signal as
well as emcomm.
WSPR on 10-MHz has been copied at 120 microwatts.
