Re: Yaesu FT-818ND Discontinued Manufacturing

You have a very simplistic view of the industry - you seem to believe that every hard-won technical advancement beyond superhet receivers with 'slabs of quartz' is a step backwards performance-wise and nothing more than an effort to build in planned obsolescence because anything more specific than a generic thru-hole component will ultimately render the device useless when it can't be replaced.
Then, in a startling turn, you attack Collins, the company that represented the state of the art in radio transceiver design when radios were built with your preferred discrete, off-the-shelf components!
My original statement still stands:
Yet, somehow Yaesu can't source filters for their radios...?Yaesu can sell those 'lumps of quartz' for $150/ea, if there was a source, they'd still offer them.

An SDR is taking everything and only tailoring it's output to end user expectations.
But at the end the DAY, unwanted signals still enter the "front end",there are still screwing up your
total dynamic range algorithms and FFT only sugar coats the problem.
But lumps of quartz have real RF rejection.
A good old fashioned superhet with tradition parts can be fixed.
An obsolete FET or whatever can be easily substituted for something else when it's blown.
A custom IC not publicly available, no chance.
I buy a rig to invest in, not a crappy iphone with built in obsolescence.
Any why is a company like Yaesu with? some 60 year heritage, commercial input from Motorola,
Marantz, Standard Horizon, Sommerkamp etc placing itself at the mercy of ONE single point of failure,
Colllins, a company who's peak was not long after WW2 FFS !
They can easily spend a few $'s, make a simple quartz growing lab and make their own.
It's what the Chinese do every day !!
