Just noticed I have lost all the horizontal channels on both satellite
rxs......is it as simple as a duff lnb or coupled with the fact I am
getting
a shock off the outer of all the f connectors could it be a cable/plug
fault
.....I get the shock with either rx switched on or both on so probably
not
the rx.????...not got any test equipment here at the static van so
probably
start with bringing down a new four way lnb the next time I come down ?
....if that doesn't cure it check all the cables for shorts? ....anybody
had
this fault?...


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.

you're having a laugh shirley ? .....


No, not at all.

There was a time when wireless amateurs had to know some electrical
and electronic theory.

That was before the major skill requirement decended to figuring out
how to open the box the latest LED festooned pile of garbage came in.

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