Rich asked "On HF/MF skywave, is a 58% increase in power out (2db) noticable
at the
Rx end?"

That all depends upon how you define noticeable.  If your s-meter is sitting
at S-9, and assuming that 6 db per s-unit is the standard, that would mean
the s-meter would change from 54 db to 56 db - or 2 db over S-9.  If the
variation in signal strength is greater than that due to reflection, then it
would be difficult to detect a 2 db change and not noticeable.

However, if the signal was at or near the noise level, then 2 db increase
could make the signal more easily read.  A 2db increase is like Christmas to
someone using a single yagi for moonbounce.
