[Elecraft] Interesting Read: Dinosaur Concepts - why are we always so conservative?

[Paul - WW2PT]

"However, the radio hobby industry perseveres with narrow-band design
concepts even to 
the present day - usually with automatically-switched front-end BPF's, the
rare exception 
being the tracking preselectors in the pioneering JRC NRD-545 (1998)."

Not to quibble over details but JRC's varactor-tuned front end filters
predated the NRD-545 by 12 years and two models -- it debuted (at least in
their amateur receiver line) with the NRD-525 in 1986 and was carried over
to the NRD-535 in 1991. It was also incorporated in the JST-135 and
JST-145/245 treansceivers, both of which also preceded the NRD-545 by years.
(Not sure about the JST-125, never did get my paws on one of them...)

73 de WW2PT <-- your friendly resident JRC quibbler. ;-)
