If there is someone out there that can devise a circuit for receiver RF
front-ends that will clip stronger signals and noise, while passing weak
signals untouched, most existing modern radios could be instantly
transformed into super receivers.  The chips probably now exist.   > 73, Doug /

Years ago in (maybe the RSGB TT?) there was an analog, discrete parts, circuit which compared a delayed input to a rate of rise input and blanked or attenuated anything that came up faster than your desired signal. Was done at the IF level as existing parts needed a higher signal level to function. Filed it away somewhere as it looked promising as something before a Cheby sharp filter.
