As some know, I've had a pipe dream for over 50 years that someday
I'd produce a world beater RX but from older technology (and some
have responded in an abusive manner thereto, going against the
gentlemanly
tradition of amateur radio, shame on them :-( )
I've spoken in the past about how much I both admire and enjoy the haptic
and visual interface of the old Eddystone valve RXs, with the
flywheel-loaded
tuning knob and the slide-rule dial, but nowadays it would be senseless
not
to take advantage of the frequency range, stability and deltas of the
si570
magic chip oscillators.
So, until techology changes the goalposts once again, (and the project
goes with me to my grave!), what I now envisage, is an si570
controlled by a microprocessor, with a flywheel-loaded knob to drive it,
but
with the slide-rule dial still there, but driven by a stepper motor to
match
the tuning
of the si570, and a further stepper motor to drive the pre-selector
making
use
of the 4-gang tuning condenser waiting in the wings, that some kind
person
anonymously donated to me.
Thoughts anyone?
