Yes. I posted the text from the manual two days ago in the KX3 list. "The RX I/Q outputs from a receiver are not “flat” over an infinite frequency range; the signal-conversion process results in some slope (decrease in gain) as you move farther from the center frequency. In the case of the KX3, the signal will be reduced by about 2.5 dB at +/- 24 kHz, 4 dB at +/- 48 kHz, and 7 dB at +/- 96 kHz. The spectrum amplitude on the display, including the apparent noise floor of the receiver, will “roll off” by these amounts." (page 26)
I would not be surprised if they corrected for this in the PX3. wunder K6WRU On Apr 5, 2014, at 1:55 PM, Barry LaZar <[email protected]> wrote: > Good question.
