"For an answer to your question about relative sensitivities of CW, WSPR, and some of the other modes implemented in WSJT, let me suggest going to the "References" link on the WSJT web site, http://physics.princeton.edu/
and select reference #11. Table 3 on page 9 gives the information you asked about. The difference given there is about 11 dB, in favor of WSPR over ear-and-brain CW. For most operators, the difference is more like 15 dB."

As WSPR is so effective I asked Joe, K1JT, what the difference is between WSPR and "ear-and-brain" CW. This is his very helpful reply:

Hello Roger, thank you for this entry. I came back to this entry several times. The data you refer to, enables us to determine the power that should be used in WSPR compared to CW by ear. Thanks. 73, Bert
