I read recently a simpler definition of RX: The ability to receive desired
signal and reject ALL others!
With present day semiconductors sensitivity is easy, DSP and quarz crystal
technology helps with filtering.
Superheterodyne in still prelevant HF architecture and first IF should be
preferably three times above highest
input frequency in order to reduce intermodulation problems. However,
marketing gurus found a niche for
oldfashioned CW operators willing to spend thousands of dollars on gadgets with
better IMD3 at 2 kHz.
I wrote once that I experienced busy hamradio bands only in Silicon Valley at
WRTC-1996. I am sure
there are no strong nearby signals at CT3 with the exception of TV ones!
I guess QEX reading of G3RZP and SM5BSZ articles is difficult so we discuss the
size of main knobs instead.
