There used to be a really cool tuner made by Sequerra which I saw in
the 1970s which had this amazing feature on a built-in scope. None of
the other tuners made at that time which had scopes in them seemed to
have that function (I actually bought a Marantz ST600, though for the
AMAZING sound, not the scope)

Does anyone know why this technology died a death? Surely this could
be useful now, as well as being useful for broadband signal detection,
showing signal strength as well as how stable the signal is? Or has
the concept of having a scope in a tuner died a death for some
reason? Surely it should be easier now with the prevalence of LCDs
being used for everything in sight?

Or are there any WiFi applications which can simulate this function?

It adds to the tuner's cost without providing a feature most users need.

You can buy an inexpensive WiFi detector at RatShack and elsewhere.

See above.

FM is no longer a significant program source for many listeners, especially
with the decline in classical and jazz stations.

I would like it for diagnostic purposes, to see when (and by how much)
my cable company's signal drops off, as well as which nearby WiFi
signals are experiencing similar problems. I use RCN and their signal
wavers around like mad. No app l know of can show any of this: Most
of them are dependent on the beacon to show just whether there is
anything there or not and how strong it is when it is beaconing. I
wonder if what I am asking for is a practical impossibility? Surely
routers are transmitting all the time even if the beacon only
transmits at certain intervals. It would b interesting to see an app
like this show things like packet loss etc.
See above.

Dont take your point: In my area there are plenty of classical choices
and with a knob tuner, it is interesting to see where the stations are
and how strong they are, though this signal strength business doesnt
seem to be as important as it is with WiFi.

You're fortunate, but for the country as a whole, classical and jazz are in
a decline. And tuners are made to sell throughout a country, not just in one
area.

As for the demise of classical music FM stations, in the Monterey Bay
area, we have KBOQ:

In the SF Bay area, there is KDFC:
<http://www.kdfc.com>

.... which is only a faint shadow of its former self, now playing nothing
but "easy listening" classical pieces and war horses.

When I moved here, not only were there 2 FM classical stations, but KDFC
broadcast in *AM* as well (there were a couple of other classical AM
stations as well). So I'd say classical music radio is in a rather steep
decline.
