I've never operated JT65, so maybe some of you experts
can answer a beginner's question.  Searching on line,
it is difficult to get a definitive answer to how much
advantage it has over CW, but the number seems to be
around 10 dB.  Maybe not even that much if the receiving
station is using an SDR with very narrow CW bandwidth.
So a CW station with a legal limit amplifier
gets out better than a JT65 station without an amplifier.
But I keep hearing about JT65 stations running low power,
not even 100W barefoot.  It seems like if we could get
antenna challenged stations to run high power on CW,
there would be no need for JT65 in the first place.
Do any significant number of 160 meter QSO's occur on JT65 at
legal limit power levels, like they routinely do on EME?

Having WAS on 160 Qrp posted on the wall always reminds me of the effort of 
operating and the time spent learning about antennas that actually work over 
the long haul distances required.
  Instead of taking many minutes many of the qsos were quick and snuck in 
between static crashes as opposed to slow and determined.
  To each his own. Work whatever mode works for you.  Does using ssb rather 
than cw change the value of the Q? Only in the eye of the beholder. Not so much 
to the been there done that kinda guy.

Make this a great day

WSJT-X 1.7.0

There is JTDX, based on WSJT-X, but with some additional tweaks for the HF user.
