I wouln't think the events are related. A working recceiver has a very
"feelable" ac Voltage on the LNB output.

There is not usually a ground on the receiver and the capacitive
leakage from mains to equipment provides the "tingle". I do ground the
receiver now when setting up a system on damp ground.

With no direct means of measurement a spud will detect Voltage and
polarity.

Plus gives a blue ring.

I did have a discussion with a marine Engineer who said that the spud
had to be a King Edward. I don't actually think this is the case, but
since the introduction of DMM's I never really had reason to check.

I have never had a tingle off the outer of an lnb plug before only this set
up.......I will get a new lnb because they a dirt cheap these days and I bet
the tingle will go but if it doesn't I will test the four cables for shorts
and re-plug them...just wondered with no horizontal signals and full scale
vertical it would be an lnb fault causing the "tingle"...... .thanks

No, not at all.

There was a time when wireless amateurs had to know some electrical

That was before the major skill requirement decended to figuring out

No Mains is ac. If you have leakage it is normally capacitive. DC does
not pass through capacitors.

Capacitors in fact are used to block DC and pass the ac component.

You may have a few class C amps that use this feature.

Now this is a difficult concept, so stay with it.

Your LNB will require a Voltage of around 18V DC.

Between the braid and inner, you will measure 18V DC.

The 18V DC can be present on a cable that is 70V ac or more above
ground.

Grabbing a humble spud would enable someone with a brain cell to
identify the polarity and where the ac component was introduced.

Do you go on air at all?

Does the nice man at the shop show you how to tune a wireless in?

you are a sicko ......dead simple each receiver is providing the voltage to
the lnb and there is a voltage on the outer of the F plugs at the lnb so
must be the lnb that is doing it and giving no horizontal signals to either
receiver....no?...and you know where you can stuff your potatoes....

if you think the lnb is switched by ac voltage I think you are the one
with
a problem not me.....go away


No Mains is ac. If you have leakage it is normally capacitive. DC does
not pass through capacitors.

Capacitors in fact are used to block DC and pass the ac component.

You may have a few class C amps that use this feature.

Now this is a difficult concept, so stay with it.

Your LNB will require a Voltage of around 18V DC.

Between the braid and inner, you will measure 18V DC.

The 18V DC can be present on a cable that is 70V ac or more above
ground.

Grabbing a humble spud would enable someone with a brain cell to
identify the polarity and where the ac component was introduced.

Do you go on air at all?

Does the nice man at the shop show you how to tune a wireless in?

AB

you are a sicko ......dead simple each receiver is providing the voltage to
the lnb and there is a voltage on the outer of the F plugs at the lnb so
must be the lnb that is doing it and giving no horizontal signals to either
receiver....no?...and you know where you can stuff your potatoes....

ROTFWL

Yes indeed, I see it all now.

Have you any more of these LNB's, it sounds like you have encountered
a source of perpetual motion.

Not a lot of use without an interpreter.

If the LNB supples the power to the cable a Sky expert isn't a lot of
use.

One of those Crystal danglers would be more appropriate, you know,
start a crystal swinging on a string.

Either that or prayer is good in such situations.

Daleks are still the most plausible really, they allow the laws of
physics to hold, no matter how unlikely the scenario.

Yes. They all do it. Absolutely all of them except early Amstrads. If a

shock off the dish.
