Typical radio promotion gimick.

Here is an excerpt from Chuck Blore's future book showing how
things were done 'back then'
-----------------------
When High Fidelity was a big deal in records,
Gordon's stations were all Hi-Fi Radio."

"What made them Hi-Fi. Was that just a name?"

"Oh no. He always made it seem very special. And very real. When we
began promoting "Hi-Fi is coming to radio" all the stations were told
to back off the higher frequencies of the actual signal a little bit
each day for two weeks.

Without anyone really noticing, at least that was the theory, the
actual stations signal gradually became kind of dull, and duller. But
then, we had the big announcement ... `Ladies and Gentlemen. Welcome a
new millenia in radio broadcasting. This is K E L P HI-FI RADIO' and
with that we slapped all those frequency adjustments back to normal
and, Oh God! What a difference."

-------------------------

Don't believe 50% of what you hear on radio promos, the ignore the
remainder

It's only the voices in your head. You've taken your tin foil hat off
again, haven't you.

Call letters of the station please?

Is this the same as "IBOC" digital radio ? AIUI this is the US digital
radio system, where radio stations broadcast a digital carrier close to
their analogue one. It is VERY different to the European DAB radio system
which is usually implemented in a different frequency band. (In the UK the
DAB system occupies Band III, whereas VHF FM occupies Band II)

He probably doesn't remember, but dollars to donuts he has a
recording of it on cassette tape somewhere...

When the broadcaster doesn't know what is going on with current technology,
it doesn't bode well for new technology. A snippet from that page:

=================================================================
What does it mean that 98.1 KING FM is broadcasting in HD Radio=3F Technology?

For those with digital receivers, the noise and interference that cause the
static, hiss, pops, and fades heard on today's analog radios will be
virtually eliminated.
=================================================================

There is no static, hiss, or pops on FM radio. Fading (which includes loss
of stereo) is the only artifact of a reduced-quality FM signal.

No, if the signal to noise ratio is that low, there *is* no usable signal
at all, and what you hear is the amplification of "nothing"...basically
the same thing you hear when you tune to a spot where no station exists.

True. If the signal fades, eventually you'll lose reception of *any* type of
radio transmission. AM, FM and digital simply die different deaths, viz-

AM - programme volume decreases and gradually disappears into noise.
FM - noise increases and gradually overwhelms programme.
Digital - nothing noticeable at all at first, then screetches and yelps and
suddenly disappears altogether.
