I would say that it depends. If you are already 20 or 30 over 9 at the RX end then probably not. If you are right at the noise floor be it noise generated by any factor (bad band conditions, atmosph

I would agree, with one added comment. The definition of dB, as I remember, 1dB is the unit of sound level change that is detectable by the human ear. So if you are at the noise floor, yes it will ma

In marginal conditions, such as daytime on the lower bands, or at the edges of a skip zone, etc, where the signal is at or in the noise, adding 2 db to your signal is helpful. For certain digital mod

The definition of db is 10 log (powerA/powerB) and has NOTHING TO DO with human perception. (Where DID that old wive's tale come from...) The landmark Bell Laboratories study on how well average peop

Another angle to consider. 1-2 dB better signal may not be discernible on any given QSO. But over the course of a 48-hour DX contest, it may mean several dozen more European QRP stations with indoor

Maybe another way to put that: in a 48 hour contest, you can bet some significant number of contacts will individually qualify as marginal conditions (as in QRP & indoor antennas), and the 2 db will

HUH? You mean if 2 dB makes the difference between a QRP European hearing YOUR KW or not, do you really think YOU will hear HIS 5W? I think you need to re-think this argument Pete :-) I'll go along w

As a purely logical matter, we must accept the fact that any increase in ERP produces a detectable difference in signal strength. Small increases in gain may require more perceptive instruments than

Is there a chance to read a signal that produces 0 (zero) dB S/N ? What does it happen increasing that signal by 2 dB ? Is it detectable a 2 dB S/N ? Two divided by zero is equal to ? ....sleep well.

A signal to noise ratio of 0 dB doesn't mean there is no signal but all noise; it means that the difference in amplitude of the signal and noise is 0 dB and that the amplitude of the signal and the n
