Postage-stamp sized radio?
 

Having currently employment within a Japanese manufacturer of
WCDMA mobile phones and thus being exposed to the "Innards" of
such phones; following the historical challenges of making a transceiver
that would fit into a tobacco tin, is it perhaps now the time to
issue a challenge to come up with a complete transceiver design
fabricated to the size of a postage stamp?

Some of the circuits that I am engaged in testing have components
that are smaller than the smallest blob of solder I can melt!

Perhaps it is time to extend my soldering iron with a tip fashioned
from a dressmaker's pin?

Ahh a rehab course

see why not, but what's the point?

For mailing a radiogram, perhaps? Package tracking, though RFID seems
to the modus praesto.

Certainly many sinister reasons exist as well for such a small device.

It can't be smaller than Beanie's brain.

Idiot.

Why the attack? A postage stamp sized transceiver is certainly quite
feasible with today's technology. It won't be QRO, but an entire transceiver
can be implemented in that size ... do a web search on "Zigbee" and I'm sure
you'll find many examples

Idiot.

Why the attack? Why the _INFANTILE_ attack? It is
an unfortunate indication of the extent to which incurable
CBers, all those who buy their rigs off-the-shelf and
send them back to be repaired, are infesting Ham Radio.

I append a short article to assist.

What is Ham Radio?

Ham Radio is a technical pursuit for those who
are interested in the science of radio wave
propagation and who are also interested in the
way that their radios function. It has a long-standing
tradition of providing a source of engineers who
are born naturals.

Ham Radio awakens in its aficionados a whole-life
fascination with all things technical and gives
an all-abiding curiosity to improve one's scientific
knowledge. It's a great swimming pool, please dive in!

This excitement causes a wish to share the experience
with ones fellow man, and shows itself in the
gentlemanly traditions of Ham Radio.

Radio Hams are in a unique privileged position in that
they can construct and operate their own equipment! No-one
else has this privilege. Users, such as broadcasters,
the po lice and armed farces, CBers and mobile phone
users have to purchase ready-made gear. Manufacturers
are not licensed to operate their gear. Radio Hams
are qualified to design, build and then
operate their own pieces of equipment. They do this
with gusto, and also repair and modify their own
equipment. This is a privilege well worth the effort
to gain, and one to be jealously guarded.

The excitement that drives a Radio Ham starts with
relatively simple technologies at first, perhaps making
his own Wimshurst machine and primary cells. Small pieces
of test equipment follow, possibly multimeters and signal
generators. Then comes receivers and transmitters. It is with
the latter that communication with like-minded technically
motivated people takes off. The scope for technical
development grows with the years
and now encompasses DSP and DDS. There is also a great deal
of excitement in the areas of computer programming to
be learnt and applied.

The technical excitement motivates Radio Hams to compete
with each other to determine who has designed and manufactured
the best-quality station. This competitiveness is found in DXing,
competitions and fox-hunts.

-----OOOOO----

However, beware! A Ham Radio licence is such a
desirable thing to have that there are large
numbers of people who wish to be thought of
as Radio Hams when, in fact, they are nothing
of the kind! Usually such people are a
variation of the CB Radio hobbyist; they buy their
radios off the shelf and send them back to be
repaired; they are not interested in technical discussion
and sneer at those who are; they have no idea how
their radios work inside and have no wish to find out;
they are free with rather silly personal insults;
they have not satisfied any technical qualification
and their licences prevent the use of
self-designed-and-built equipment.

These CB types engage in the competitive activities
with their Cheque-Book-purchased off-the-shelf radios
in a forlorn effort to prove that they are Radio Hams.

No _REAL_ Radio Hams are deceived by such people!

Well do so - then do us all a favour and stick it up your arse!

Then, and only then, switch it on.
