- I have an interesting GIF image from Funk Amateur (Feb/1999) that shows the relative width of CW signals at 20wpm and a clean PSK31 signal. If anybody is interested in looking at this, I have placed

- The noise floor does NOT drop - and, of course, the noise power is larger compared to the original cw signal. However.... There is a curious psycho-acoustical phenomena dealing with noise - a weak si

- If a modern synthesizer is used to key the radio and the radio is not running in full QSK mode (or if separate synthesizers are used for RX and TX), I suspect that the only time settling and bounce s

- Please explain why my 100W produces S9 signals in Europe. If I put on my 500W amplifier, the signal in Europe sometimes increases to S9+20 (no Lulu, this not a case of S-meteritis). Of course, more o

- etc... Although I don't really understand this area at all, it seems to me to be reasonable to assume that there are definite non-linearity's in the ionosphere. How do the various layers change durin
