Does anyone know if they exist and if they do where I can
purchase one? Dick Smith and JB don't have any as of yet.

I got an MP3 player much smaller than a walkman and it has an FM radio.

John said:He said *digital*.
With the CPU, logic decoding and the rest, there's lots of hardware
overhead there, would likely be a while before we see the size of
digital sets approaching the size of current smaller crop of FM receivers.
Clifford said:Funny that, because you can get a dual-channel digital TV receiver
in a USB stick format. The radios will come, they just have a
smaller market. It's nothing to do with the chip size. Some of
these USB receivers have an ARM9 processor in them, so they could
be easily programmed as radios instead of TVs.

David said:Leading Edge have a very nice little digital radio - the Digitech AR1745
Frankly I can't for the life of me work out what's wrong with analog
radio that we need to ditch it and replace all our old receivers with
digital ones. Pointless waste of money.

Phil said:Be a shame to lose AM band radio though, would mean the end of super simple
recivers like "crystal sets".
Every second kid still builds one of them - right ???

Clifford said:Looks nice, is also sold under its original branding as Redsun RP300,
but it's a digitally-tuned analog radio, not a digital radio.

John Tserkezis said:You bring up an interesting point. What will the schools of tomorrow
bring?
Ok boys and girls, today, we're going to build a digital radio receiver:
First we have to learn about radio theory,
Then digital.
Then RF design in the commercial radio band
Digital design in logic, microprocessor, and DSP.
Embedded software design, and audio stream decompression techniques.
On the hardware side, first we learn about basic soldering.
Then PCB manufacture,
Then surface mount soldering.
Easy, that bit should only take about a decade or so.
The hard bit is the encryption, because we would be violating any number of
licences to teach you about the very last critical bit that would make your
radio useful at all.
Since that technique is not viable, we'll do it the easy way.
We'll get you to go to the Aldi's around the corner and buy a $25 receiver
from them.
If you manage installing the batteries and getting it to work, we'll
consider it a pass.

electronics. Things like flashing LEDs and PIC programming didn't cut
it. Nothing other than a fully fledged robot would do.
It's a whole new world guys. Get used to it.
