Even when this feels good for a start, I am afraid it falls a bit
short, because from 15 to 6 watts there only a variation of 3.97 dB
to cope with a 9 dB variation in SNR, from -6 to -15 dB.
I feel it also should be correlated to the other guy's ERP.

Hi Julian and Ron,
I agree with you about the propagation being the
most important factor in JT9 QSOs. Using about
5 Watts, I have received reports from -27 to +5.
A power formula (that works for me and my antenna
as a starting point) is to reply to someone at the
absolute value in watts of his signal strength -- for
example, if I receive him at -06, I answer with about
6 watts; if I receive him at -15, I answer with about
|his sig strength| * 1 Watt) = my power out
I did have an issue about a month ago with TX: my
rig/laptop combination works best with the WSJT-X
internal DirectX sound drivers.
Tnx es 73 de Bill K WB2SXY
