I found "IEC 60169-2" on
http://www.itwissen.info/definition/lexikon/Antennenstecker-antenna-connector.html
(The text is German, though).

Another search for "IEC 60169-2" led here:
http://en.wikipedia.org/wiki/IEC_169-2#Belling-Lee

So, "Belling-Lee", as others pointed out, would be correct.

Nothing that you would understand. Leave electronics to those who
know what they are doing, but practice your pathetic trolling somewhere
else.

Thats the nice thing about freedom of choice. You can go to the shop down
the road from me . Pay an upfront 17 GBP and 80 percent of the time and 2
months later, he says he cannot get the replacement part - sorry, no refund.

At least he's honest that it can't be properly repaired. Most of my
repair work can from people who had been screwed by hacks who patched
things together just long enough to get paid. I either repaired the
item, or told them it wasn't worth the money.

They were all free to chose, and chose wrong the first time.

Anyone any experience? Coil is fine. This is almost hair-fine
phosphor-bronze ribbon suspension , not hairspring and jewels. A ribbon, top
and bottom, holds the coil frame and passes current. Each ribbon is soldered
to the frame then passes through a hole in the offset-rotatable anchor ,
passes over the rounded edge of an open end of a U-shape of manageable size
phosphor bronze spring , and soldered along the arm of that spring. The
solder point to the frame has failed from a jar / knock. So both U springs
are now opened to a V in comparison. I have tried solder to the end of the
fine ribbon and the stub on the frame, both take solder fine but not joined
up yet. There is enough length of fine ribbon on the broken side to resolder
to the coil frame , pass thru the hole and anchor off , on its u-spring
anchor farther along than originally.
But how to bring the open-U springs back to proper U before soldering the
anchor point. A matter of making a jig to compress or some sort of external
spring over them ? And of course I've not seen a functioning movement. I'm
assuming setting up as U and then opening out a bit with the jigs removed,
or would the jig need to compress to more than U and then open out to U with
jigs removed, normal use.
Pushing down on the spring of the good end and letting the coil frame drop,
with gravity, it seems to be centrally aligned over the pole piece, when
the spring is a proper U viewed on side.
Where would one find , even robbing, short lengths of such rbbon if it was
required?

A couple of years back, a colleague gave me a professional Ferrograph audio
test set. This has a large format precision meter on the front, which has
the same vertical 'twisty' ribbon as the coil / needle suspension scheme. It
was broken when I got it. As there was little chance of being able to get a
replacement movement, I figured that repair was worth a go. As I recall
(it's been a while ago now) I simply fed the wire back through the hole in
the U-frame and held the frame in tension pushing down on pointy tweezers in
one hand, whilst using the soldering iron in the other hand. I had
pre-tinned both the wire and the frame, and simply bent the end of the wire
over with the tip of the iron, whilst letting a small 'blob' of solder
previously fed onto the iron's tip, flow into the joint. I was absolutely
amazed when I let go of it all, and blew on the pointer. It went from one
end of the scale to the other, as smooth as you like. No issues with
centreing or sensitivity or whatever. I seem to think that I struggled
slightly to get a good zeroing action from the zero offsetting screw in the
perspex cover, but I did manage it in the end. I can't remember why, or how
I got it to zero in the end, but I did, and it has remained correct since.
The unit is in daily use, so it has been an effective and long-lasting
repair.

Make no mistake, it was a delicate and fiddly procedure, with lots of
holding of breath and magnifying glasses and so on, but quite do-able for
the likes of you who enjoys challenges like this. Go for it. You've nothing
to lose.

Likewise no chance of a replacement . Reminds me Test Instrument Services,
Totton Hampshire no longer seem to do this and meter rewinds , keeping
ancient ship-bourne engine/generator monitoring meters of the world's
merchant ships going
Certainly a job fully under a x4 or so illuminated inspection lens. This
Sifam one you can rotate suspension anchors at either end , but there is no
user accessible adjustment of zero once the meter scale is set in the
housing.

I think the sensible route would be . A loop of copper wire around each U
spring and twisted ends until parallel spring arms. Offer up the ribbon and
solder up and then while a finger over each spring, in turn, cut the copper
wires and gently release finger pressure. I'd rather have too little tension
in the U sptrings and so the fine ribbon, than too tight.

I've never needed to repair that type of meter movement, but it sounds as
though what has been described is likely to be the Taut-Band type of meter
movement.

I never looked inside one but all those broken Pye/Cambridge? moving spot
galvanometers presumably had that system. While at it anyone know what the
suspension is in Megger insulation tester? that dead springless movement,
jewelled without hairspring? - I've never looked insiside the meter movement
of one

First try to attach the ribbon to the frame. You might want to remove
the magnet first (if it isn't a core magnet type meter).

Remove the solder from the U-spring, especially near the open end with
solder sucking wick.

You have to press down the spring at the broken side more than the final
position so it will pull the other side into position one it's released.
You have to try that out. Too few tension is just as bad as too much
tension, because the frame wouldn't be in the right position then.

Solder the ribbon to the U spring near the turn of the U. Release the
spring, check if the tension is right (axial position of the frame). If
it is, you can now slightly adjust the axis of the frame now by pushing
the ribbon left or right. Now fix the ribbon near the open end of the
U-spring. Check that the pointer moves smoothly over the whole range by
slightly blowing at it.

Re-attach the magnet/scale (if removed).

Check equilibration (set the pointer to about 25% of the range and check
that it doesn't move when the meter is tilted back/forth; repeat for 75%).

Set the pointer to zero. Check sensitivity. If you can adjust
sensitivity at the electronics, do so. Else you have to move the
magnetic shunt (small iron strip at the magnet) to adjust sensitivity.

Who cares which 'grows' fastest. If you want to believe in mythological
beings, fine. Don't force others to believe it so you can reinforce your
belief.

The only way to defend yourself against imbeciles is to speak the truth.

I haven't measured the output of a "100W" CFL. However, they're subjectively
quite bright, on the borderline of "too bright to stare at".

Are they as bright as a 100W incandescent? The light is spread over a larger
area, so it might not look as intense. Regardless, the opinions of some
reviewers that these are not "truly" 100W equivalents are suspect.

I have exactly the same four-bulb package shown. All the EcoSmart CFLs I've
bought have given good service -- at least one year of several-hours-daily
operation -- including the one in my den, which runs upside-down. When they
"die", they start erratically and fail shortly afterwards.

Why, Phil, do you want people to think you're a sociopath? Are you afraid
people might not respect you?

One of these days, you're going to run into someone less tolerant than the
people in this group, and he'll smash your head in. No doubt your dying
words will be "I was just joking". Well, I'm not amused, nor is anyone else
here.

Why don't you just join Bin Laden? You're probably too old for him, but one
never knows. Perhaps the two of you can drop in on Chris and Satan.

Hi,

have a look at

(for measurement on electronics)

or

Holy crap! That's some detailed analysis.

You know, you've got the material for a pretty good magazine article

The return channels (T) are used for internet, VOIP and to order pay
per view. I used two T channels on the system I maintained near
Cincinnati. One on the main loop, and the other to connect a sub split
to a mid split community loop. The interface between the two cable
companies was a single Hetrodyne Signal Processor to convert the alien
system's channel 12 to T-10, which was fed back to our headend. The
amplifiers required two pilot channels. We used 2 and 12, so our
forward signal was on Ch 2. This was fed into their system, and routed
to their headend. They were already set up with a Ch 6 feed from one
school, so we let them keep control of the loop. I designed the
headend, which was another pair of RCA HSP, as well as the pole mounted
HSP at the interconnect. I set the levels in the shop, and was only off
.1 dB at the interconnect point. Not bad for hardline that was hung
five years earlier, and never spliced. :)


The biggest problem with the return channels is noise. Every source
connected adds noise to the system. Some return amps were switchable to
disable them, allowing the CATV operator to route a single source to the
headend. This made sense when it was used for nothing more than live
remote feeds. Fiber breaks it into small enough nodes that there is no
need for switching, and in most cases, no amplifier for that direction.

It was still better than the original copper braid coax. Even double
copper braided with a silver plated copper center conductor was
horrible. That wire sold for over $1 a foot in the early '80s. Most
ingression/radiation problems with foil shielded coax is from bad crimps
at the connectors, or wire that has pin holed and water got inside,
which wicks in the dust and salt on the jacket. That eats the foil.
