I am probably showing my age but as a kid I recall the console radios
with a very cool tuning indicator called a Cat's Eye.

Some things are gone forever and are missed. Too bad there is not a
software version of the old cat's eye.

Doesn't an S-meter perform the same function?

I remember my grandparents having such a device on their big
living room radio set. I also remember opening the back of a small table
model radio when I was older (in my teens) and being surprised
to find that one of the tubes used in it had a catseye on it. Guess they
were using an old stock of tubes in the new radios and the catseye tuner was
just an unneeded function of the tube they used.

Yah, but it's not as sexy...

My recollection is that it was called Magic Eye tuning. Maybe
different manufacturers used different names.

I recall listening to the hiss of CW in a BFO-less wooden box radio
with the magic eye winking in time to the Morse.

Looking back, it seemed like a kind of expensive gimmick in a day when
squeezing maximum performance out of the minimum number of tubes was
the norm.

It depends on how you define function!

To tune a dial and watch that green eye close up is ... well ... nostalgic.

Takes me back to 'Gooney Boxes' [the early models].

So paint the S-meter needle and 60 dB over S9 a
phosphorescent green color? I'm sure the display
on my IC-756pro could have been programmed to
simulate a "Cat's Eye Tuner". Maybe someone should
notify ICOM that it should be a feature? :-)

It was a 6E5 vacuum tube. Great indicators and they were driven
by the AGC voltage.

Been there, done that, I think I remember the tube type was a 6E5.

I don't miss it at all!

My idea of cool is the Ten Tec Jupiter on my desk beside my computer.
It has a panel and a computer display, instant warm up no drift, more
filters than I will ever need. The spectrum display is just short of
magic. I don't want to go back.

Cecil, did you ever own or use an original GOONEY Box?

Turn the dials ... watch the green eye ... !

I don't have any meaningful tuning dials or functions on my IC-706MK IIg, IC-746
or IC-756 Pro III.

A GOONEY box was probably beyond the means of anyone in
my home town. However, I remember a Philco AM/SW radio
with a 6E5 tuning indicator. I never understood the
difference between tuning while looking at the "cat's
eye" and just tuning until it sounded the best.

Don't we do the same thingee when we touch up our modern rigs for either max S
meter or best sound?

But, you are correct in your observation.

In the Gooney box the cat eye appearance was given by a properly shaped metal screen hidding the upper half of a magic eye tube (e.g. 6E5).

Well, the 6E5 is nice (I have several radios using it) but not as much as the European EM4. Similar in appearance, it has two opposite triangular dark areas (instead of just one). When tuning a station, just when one of the two triangles has got fully lit, the second triangle begins to narrow down. In a way, it is similar to a bandspread tuning system. The synchronization between the two triangles is remarkable. But I am sure there also are US-made tubes doing the same thing.
