For One and All,

Up for your consideration is the simple fact that up until now
the USA and "The World as a whole has had a uniform general
Standard of {Common Reality} of an Analog AM/MW Radio Band;
an FM Radio Band and Shortwave Radio Bands. This allowed
a World-Wide-Commonality at least in some Radio/Receiver
Circuitry.

Does the Digital Radio Future Offer the same opportunity for a
World-Wide-Commonality in some Radio/Receiver Circuitry.

WHAT ABOUT - AM / FM DIGITAL RADIO ?

Will the be a unique Digital Radio Design for AM/FM Radios
built for sale in the USA ?

And a completely different Digital Radio Design for AM/FM Radios
built for sale in The-Rest-of-the-World ?

Will Digital AM/FM Radios sold in Mexico and Canada be using
the USA Digital Strandards or the Univeral Standard of The-Rest-
of-the-World ? Will Americans have to have a Second Radio to
Listen to Digital Radio Transmissions from The-Rest-of-the-World
including Mexico and Canada ?

What is the Canadian AM/FM Digital Radio Standard ?

What is the Mexican AM/FM Digital Radio Standard ?

What is the European AM/FM Digital Radio Standard ?
- - - Who Will Africa Follow ?

What is the Japanese & Korean AM/FM Digital Radio Standard ?
- - - What Will The Rest of Asia Do ?

What will become of the standard 'portable' AM / FM Shortwave Radio ?


WHAT ABOUT - DIGITAL RADIO MONDIALE (DRM) ? ? ?

With Respect To - Digital Radio Mondiale (DRM) will the next
generation of built for sale in the USA AM/FM Shortwave Radios
have DRM as part of their built-in Circuitry ?
About - Digital Radio Mondiale (DRM)
DRM = http://www.drm.org/.

Or in the future, will their be a new breed of Stand-Along Shortwave
Radio/Receivers that are "Shortwave Only" with built-in DRM Circuitry ?

About - Digital Radio Mondiale (DRM)
DRM = http://www.drm.org/.


GOING DIGITAL - Seems to be many paths headed-off in many
National {USA} or Regional {Europe} directions where the World
Wide Radio Listener is that last consideration [.]


I Have Questions ! - Do You Have Any Answers ? ~ RHF

Early domestic-market Western European FM radios would cover 88 - 100.
Then the band was stretched to 104 in the 60s. In the late 1970s/
early 1980s, the band was stretched out to its current 108 MHz.

True export models would cover the entire FM band 88-108. Any radio
that only covered the 88-100 or 88-104 bands seen in the Americas were
brought over by immigrants.

Domestic Japanese-market radios cover the FM band from 76 to 91. I
should know, I have a couple Japanese-market FM radios. The band
between 91 and 108 is used for VHF TV audio channels 1, 2 and 3.

Eastern-European/Russian FM radios cover the 66-74 megahertz band.
That would be what we use for TV audio for Channel 2, 3 and 4.

Using a Japanese radio, you can pick up USA TV audio channels 5 and 6.

The European radios in Ecuador, which were the majority in 1966, were known
brands like Telefunken and Grundig. Since there were no FM stations, there
were only about 16, 000 of them then. Almost all were 88 to 100 MHz,
including theone in my home. Most were consoles, with a record changer and
all... in a credenza sized piece of furniture that, then, cost about $500 or
more.

The export ones in LAtin America must have been ones intended for other
markets, as they were 76 to 100. Not many of them, though.

Never saw one of these, although the Czechs often tried to sell me
transmitters full of Svetlanas.

A friend did some consulting for J-Wave, an FM in Tokyo. They gave him a
radio. It tunes the non-com band nicely, of course.

I really only care about AM DXing; from what I have read about IBOC
digital radio, is that the digital part is transmitted as both
sidebands, so it really does affect the analog transmission, except for
adjacent channel interference, because there is more energy put into
the sidebands. I believe, that digital transmissions do not carry, as
far as analog, so in the case of a pure digital receiver, it will still
pick up the analog transmissions, once the digital sidebands fade. We
should be able to use our analog receivers, even though stations are
transmitting in digital, as many of them already are, for example, 700
WLW.

Most of the few vintage FM radios I saw in Colombia were all 88-108.
But those were mostly all transistorized. All the tube radios I saw
there were MW/SW only. I brought back two, a huge Grundig and a
smaller Philco-Tropic made in the UK.

My grandmother has her 1940s Philips MW/SW set.

As you said, German and Dutch brands ruled.

I remember seeing a couple Japanaese AM/FMs in a pawn shop. They were
88-108, but these were from the 1970s. Wayy too beat-up and battered
for my taste, so I didn't get them.

But then Ecuador and Colombia are two very different animals. I'm
pretty sure that Colombia got into the FM game much earlier than
Ecuador - at least in the major cities like Bogota (now-departed HJCK,
for instance).

Most Japanese analog-tuned portables cover 76-108 anyway, so that their
owners can take the radios outside the country and have them work. In
Japan they're marketed as FM/TV.

It's a different ball game with the digital units and home/car stereos,
though. Once again, this is just from the ones I've seen and played
with.

Here is an old Polish FM radio (not mine, unfortunately):

Oh yeah, that's about the only FM radio you can pick up with them.
Here's an OLD Sanyo add-on tuner made for the Japanese market:

and an old Pioneer table-top radio (FM only, and the dial knob is
missing)

http://radiomann.hp.infoseek.co.jp/H...F6-Pioniaf.JPG

Hope he still has it. Foreign-market electronics can be a cool thing,
well....if you're a nut-case like me and collect radios.... but that's
a whole different story.

DX Ace - You forgot to say :

Thus Sayest I - The DX Ace ! ) ~ RHF

DE,

But now imagine in 2006 doing the same thing - Impossible !

With each of these made-for the Japanese, German and
American Radio Market radios had a different Digital Audio
Broadcast (DAB) Standard ! ! !

Do you now Broadcast (Transmit) in each of the
Multi-Standards so that all Radios will work ? ? ?
-Or- Do you Broadcast (Transmit) using one standard
and miss some of your potential Listeners who have
Radios that can not receive your type of Digital Signal.

For Digital Audio Broadcasting (DAB) to work World Wide
there needs to be a 'uniform' World Wide Standard for
all Transmitters and Receivers. Unless the intent is to
Nationalize and Regionalize Radio Listening and therefore
Eliminate International {Trans-Regional} Radio Listening.

As bad as Digital Radio Mondiale (DRM) may be . . .
At least it is a World Wide Standard and may be in time
technology will evolve that will enable the reduction of
out-of-channel digital artifacts.

Why Is . . . Digital Radio needed below 30 MHz ?
WHY DRM = http://www.drm.org/system/whydigital.php
DRM TECH = http://www.drm.org/system/technicalaspect.php
DRM is the world's only, open standard digital radio system
for Short-Wave, AM/Medium-Wave and Long-Wave.
DRM has been endorsed by the ITU, IEC and ETSI.

IMHO - DRM should be the 'uniform' World Wide
Standard for all DAB below 30 MHz and a 'uniform'
World Wide Standard implemented for FM Band
Digital Audio Broadcasting (DAB) World Wide.

Then for good-or-bad at least there would be a new
World Wide "Standard" 'portable' AM / FM Shortwave
Radio that would be available for all Radio Listeners
around the World. And future Shortwave Receivers


hey - it's just one radio listener's opinion ~ RHF

To me a PC Based IBOC "HD" AM/FM Radio Plug-and-Play

a PC Based "HD" Radio -IMHO- before they would buy an

I'd rather have a stand-alone radio.

The circuitry can be made better (in theory) and it's just more
transportable. You can pick up the radio and carry it to the kitchen,
the living room, the porch....

Can't do that with a computer, unless you have one of those laptops
with REAL CHEESY tin-ear speakers.

But then, radio tuner cards are pointless to me unless you make a habit
of using the computer as a sort of "skimmer" or "logger"

That would have been later. When I went on the air, in 1966, the closest FMs
were in Lima and San José, CR. None at all in Venezuela and Colombia or
Panamá, and nothing north of Lima in Perú. There were many in Brasil,far,
far away, used as STLs.

HJCK's website says the station went on the air in 1950.

http://www.hjck.com/historia.asp

"founded on September 15, 1950 with the purpose of raising the culture
level of Bogota radio..."

By the way, HJCK turned around recently and LMAed their 89.9 FM
frequency to Caracol, which in turn, plugged in the "Las 40
Prinicpales" CHR format. *shudder*

HJCK is now only heard on the internet. Bummer.

At least Cali still has HJSA on FM, the classical station owned by the
Carvajal office/business services conglomerate

If you need a PC, why not just stream the audio in the first place. I'm
not a fan of toys that require a PC. The ability to hook one up is
always nice (radio programming, GPS trail playback, etc), but the
requirement to use a PC isn't good. Standards change, the OS changes,
then you are left with junk if the manufacturer doesn't support the
product.
