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. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kW?, 144-1.4kw, 432-100w, 1296-testing*, 3400-?
