No, that\'s not how they worked.

Radios of that era had a setting named \"phone\".

You mean \"phono\". Just an AUX input but lower voltage.

Right.


And a socket. You
connected the output of the \"electric gramophone\" pickup to the phone
input of the radio, which was actually the audio amplifier section.

The radio could have a switch to disable the radio section or not, in
which case you would have to \"tune out\" the stations.

Some didn\'t think to turn off item A when using item B?!

Not a question of thinking, but of manufacturing price.

A switch doesn\'t cost much. Surely if you tune out, you get hiss.

Exactly. It\'s weird that they survived for so long without words to
differentiate colours which most of use see as being different. The various
colours at the blue end of the rainbow (blue, indigo, violet) are not as
easy to differentiate, and I can understand *those* being thought of as

It is now a legal and recognised sign to following drivers, on a fast
road, such as a motorway or dual-carriageway, that you are approaching
standing traffic and slowing quickly to a stop. As such it needs to be
activated quickly and without having to take your eyes off the road.

I\'ve never done such a thing. If someone hits the back of me they should
have been paying more attention. And since I\'m not one of those cunts who
blacks out their windows (should be illegal), the person behind can see
what\'s happening in front of me and gets an earlier warning I\'m likely to
slow down.

True, it\'s their *fault* if they hit me from behind, but if I warn them far
enough ahead, I might be saving my car from being damaged: the car is just
as crumpled no matter whose fault it is ;-)

In my last car, braking hard (emergency breaking) brought on the
flashers.

That\'s just what I was thinking would be a good idea.

It\'s a bloody stupid idea - I can see the car is braking due to the red
lights. Or I could if they didn\'t have such bright tail lights nowadays.
And what\'s wrong with variable brightness brake lights? I don\'t want to
flash my hazards without my permission, showing everyone I braked too
late.

It\'s well known that flashing lights attract the attention more quickly than
steady ones: that\'s why ambulance lights and \"wig wag\" red lights on level
crossings flashing, and why \"important\" warning lights on an appliance
flash.

As long as it\'s not confusing, I don\'t have a problem with giving extra
\"force\" to a warning than the minimum which might be sufficient. However I\'d
want to give the warning long before I was braking so hard that the
automatic hazard flashers were triggered. I\'ve not had to do an emergency
stop in either my car (registered in 2008) or my wife\'s (2015) because I
usually manage to anticipate hazards far enough ahead, but AFAIK they don\'t
have automatic hazard flashers. Maybe I should find a deserted bit of dry
straight road and try braking as hard as I dare (which is probably not as
hard as an emergency stop!) and see if the lights trigger. There may be a
limiting speed: for the same degree of braking force, they may only trigger
if you are going over (for example) 50 mph, and I don\'t want to brake in an
emergency from such a high speed unless it really is essential, not just as
a test.

The word \"México\" would be pronounced different in Spain than in Mexico.
Spaniards would want to write it now as \"Méjico\". The problem is, the
pronunciation of the letter \"x\" evolved differently in Spain than in
central/south américa, and Mexicans insist we write it with \'x\' and
pronounce it \'j\'

I used to live in San Antonio, Texas, which is located in Bexar county.
Locals pronounce it <baer>, rhymes with bare and bear, so you can always
tell if a non-local is talking because they say the \'x\' sound and create
two syllables.

But a real Mexican would pronounce it Behar, right? Two syllables,
English h, Spanish j.

That question shall go unanswered because I don\'t live there anymore,
and I didn\'t think to ask a real Mexican while I was there.

I noticed the h/j sound in Mexico when I was there, but the word didn\'t
come up that often. I think I noticed it more *before* I got to
Mexico, again from the cowboy movies, the westerns, where they
pronounced it Mehico, English h, maybe a guttural h. Those cowboy
movies were pretty good.

there was no word recognized as \'blue\' in extant texts. The white statues
furthered the idea until someone noticed the very colorful paint jobs had

No more difficult than a factory which makes 40/60/100/150 watt bulbs.

I remember in the late sixties visiting my mother village (Spain). They

was not metered.

Surely you could add more bulbs without them knowing? And what about non-bulb things?

Not just bulbs. All electrical appliances. While at university, I had a

would obviously had many more items.

Easy enough to have a tapping on the element to change voltage with a switch. I have a travel iron which puts the elements in series or parallel depending on the voltage you select, so you get the same power output.

The radio could have a switch to disable the radio section or not, in
which case you would have to \"tune out\" the stations.

I have been lucky enough that there was no strong station at the
frequency. I left a note inside so I or the next owner doesn\'t have to
hunt for it.

I don\'t think that would have been legal, certainly not in the UK.

I doubt it was illegal at that short a distance. You can (or could
recently) buy a transmitter to convert something (mp3?) into FM to go to
your car stereo. It wouldn\'t get far outside the car.


I remember reading an ancient book on building your own radio, and they
mentioned regenerative receivers with only a single valve. Some would
emit back on the receiving antena, so they said don\'t do this, it is
illegal and nasty on your neighbours. Better use two valves, isolating
the oscillator from the antena.

Sounds like a good way to annoy a neighbour you hate and prevent them listening to the radio station you don\'t like.

If course it wasn\'t (in the UK). Mains was AC or DC, and 120V (or so)
to 250V (or so).

I knew that mains was sometimes DC, but I didn\'t know that it was
sometimes as low as 120 V. I that, AC or DC, it was always around 240 V
(actual for DC, or RMS for AC).

Old mains radios had a switch at the back to set the voltage. Easier
with AC than DC as it just switched the tap on the mains transformer.
For DC there was a dropper resistor. If it had to work on 120V AC/DC the
set was designed for the lower voltage and had to dissipate the extra
power in a resistor, often built into the mains lead.

What no buck convertors?

It is now a legal and recognised sign to following drivers, on a fast
road, such as a motorway or dual-carriageway, that you are approaching
standing traffic and slowing quickly to a stop. As such it needs to be
activated quickly and without having to take your eyes off the road.

I think that the legal way to do it here is touch the brake lightly
several times to make the red lights blink.

\"touch the brake lightly\" when you need to do it hard?

Tapping the brake means \"there\'s a cop ahead, do not overtake me\".

When the deer jumps out of the hedge in front of you and stays
mesmerised and stationary in the headlights?

The one I hit didn\'t. It was too busy chasing the females. It didn\'t stand a chance at 90mph, especially when the canoe on the roof sliced it in half.

That cost me £40 to repair!
