The thing was made in CHINA!!!  Need I say more?  They just got

buy ANYTHING made in China since that happened.  I recently walked out

RE: [Repeater-Builder] Re: RadioShack Recalls Power Supplies Due toElectrocution and Fire Hazards

[Eric Lemmon]

Bob,

Maybe they are, but probably not.  Christmas light sets must have a
polarized plug, in order to be NRTL listed.  The wider plug blade is
supposed to go into the wider slot of the receptacle which, in a
properly-wired outlet, will be the neutral (grounded) side of the power
circuit.  This arrangement ensures that the screw base of each lamp in the
string is close to  ground potential, minimizing the shock hazard if a
fingertip touches the metal when a lamp is replaced.

In your case, with reversed polarity on the power outlet, the lamp bases
will be hot (electrically) and thus pose a dangerous shock hazard.  It would
be a good idea to unplug the lights before changing out a lamp.  Of course,
if the light strings are not NRTL-listed and/or are polarized incorrectly,
the receptacle polarity becomes irrelevant.

73, Eric Lemmon WB6FLY

Has no one seen my reply to this & like messages?

It will be fixed, but by a professional. With my luck, the circuit
breaker 
is probably wired to the neutral line as well so all I'd do is end up 
killing myself trying to fix a simple problem. When I get the
electrician 
out here, I'll have him check all that. In the meantime, Christmas
lights 
are safe to use on that outlet.

RE: [Repeater-Builder] Cables on Duplexer

[John Transue]

Bob,

 

Thanks. I have someone with good equipment coming Sunday to check it out
and re-tune as needed. I'll let you know what we found.

 

Re the de-sense, there are two other antennas close by but both are for
much higher frequencies. The three feed lines all go down the same
conduit. We are using 7/8 Heliax and I believe the others are smaller
Heliax or hard line. 

 

I plan to replace the cables in the cabinet when new cables (now
ordered) are ready.

 

John

Re: RE: Re: [Repeater-Bui lder] Re: RadioShack Recall s Power Supplies Due toEle ctrocution and Fire Hazards

[Ron Wright]

Eric,

Yes having UL or any other on one part would not mean all is UL or CSA or any 
of the other certifications.  I would think this would be a violation, but 
guess not since the UL is on the piece that is UL listed or registered.

Most people don't realize that UL is not a gov certification...UL was, I think 
still is, a private business that has gotten the seal of approval of many gov 
and other agencies.  Most gov require it for equipment in businesses.  It is a 
good safety issue and looks good in court.

Also having UL does not mean the equip works or meets specs except for the 
safety and manufacturing spec of UL.  The equip could not work at all and be 
junk, but pass UL.  UL is primarily certifying the equipment meets UL safety 
specs...you will not get hurt if used properly (don't open the box and stick 
you tonge to the solder joints).

I've been thru one UL certification and it was a joke in a way.  They did do 
good engineering and done to their spec.  Only problem we ran into was a fan 
was not UL so they wanted to test it to make sure it would not cause a fire 
hazard if say someone put a screw driver in its blades.  We just replaced the 
fan with one that was UL.

As for the colors most of the certification agencies have cross colors such as 
the green w/yellow strip required by other countries.  UL will accept this as 
the safety ground.  The other colors can also be used in this manner.  One sees 
so many power supplies that have all kinds of certifications so they can be 
sold in many countries.

RE: Re: [Repeater-Builder] Re: RadioShack Recalls Powe r Supplies Due toElectrocution and Fire Hazards

[Eric Lemmon]

Ron,

Many people see a UL tag on the power cord and ASSUME that the equipment is
UL-listed as well.  Bad assumption!  There are a gazillion products coming
out of Asia that are equipped with UL-listed cord sets, but the equipment
itself might be junk and not qualify for listing.  Some imported equipment
may have counterfeit UL labels; a genuine UL label has a holographic feature
that is difficult to forge.  In any case, UL only inspects the design of the
product and periodic samples;  when units are manually assembled by cheap
labor, it is easy for mistakes to occur during manufacture.

Incidentally, UL (Underwriter's Laboratories) is not the only NRTL
(Nationally-Recognized Testing Laboratory); there are a number of Listing
Marks that are acceptable in the United States, and UL is just one of them.

Part of the wiring problem may be due to differences in color-coding of the
power cord wires.  In the United States, the standard color code for 120 VAC
cords is:  Black for hot, White for neutral (grounded conductor), and Green
for the equipment grounding conductor.  International cord sets use a
different color code:  Brown for hot (think "warm color"), Blue for neutral
(think "cold color"), and yellow/green for the equipment grounding
conductor.

I wonder how this happened. I am sure the supply is UL listed (no such thing
as US approved) so looks like something got over looked or a change occured
at RS manufacturing.

In the US the safety ground and neutral both go back to the same place in
the power panel (fuse box). Most of the time both are insulated with
different color wires and often the neutral is a size larger wire (not
allowed with new code), but with the RS supply this wire size would not be a
problem.

Yep fix it.  Simple thing to do after you turn off the breaker feeding it.  No

[Ron Wright]

The black wire is the hot and don't think this is the problem.

The neutral and safety grounds are reversed from what I have read.  Reversing 
these will solve the problem.

Don't mess with the black or hot wire.  If it is wrong then you had better have 
RS do the mod.

RE: [Repeater-Builder] Cables on Duplexer

[John Transue]

Bob,

 

Thanks. I have someone with good equipment coming Sunday to check it out
and re-tune as needed. I'll let you know what we found.

 

Re the de-sense, there are two other antennas close by but both are for
much higher frequencies. The three feed lines all go down the same
conduit. We are using 7/8 Heliax and I believe the others are smaller
Heliax or hard line. 

 

I plan to replace the cables in the cabinet when new cables (now
ordered) are ready.

 

John

OK, now I see your reply. Don't know why this text wasn't there on your 
original reply.

2 dB is rather high for a UHF duplexer. However, you've only moved the 
duplexer less than 2% of it's original frequency, so I doubt that any of

the cables would need to be replaced as a result of the frequency
change.

You're also experiencing a bit of desense as well. Might be worth 
rechecking the duplexer tuning & loss on good test equipment (spectrum 
analyzer with tracking gen. or better yet a VNA if you can get access to

one). However, there are many other possible causes of desense. The most

common I run into are mixes caused by bad hardware in the near field of
the 
antenna (other bad antennas, feedline, loose tower joints, etc.).

The cheap outlet checkers will detect reversal of the hot and neutral, but 
cannot detect reverse of the neutral and safety ground due to they both connect 
to the same point in the power panel.

The checkers will detect if no safety ground is present.

FW: [Repeater-Builder] Cables on Duplexer

Bob,

 

Here it is again. Let me know if my message doesn't appear. Thanks.

Bob,

 

I don't have a way to measure this accurately on the receive side, but
just using a signal generator and my ear, there appears to be about a 2
dB loss in the duplexer. 

 

On the transmit side, using a transmitter and Bird power meter, there is
a 2 dB loss in the duplexer. Power in: 94 w; power out: 60 w. Reflected:
2 w. 

 

I don't have a good way to measure the isolation, but using a distant
transmitter, that transmitter had to use about 2 w when the repeater
transmitter was on and only 1 w when the repeater transmitter was off.
It appeared to me that we were getting a little de-sensing.

 

The motivation for this re-tuning of the duplexer is that the repeater
doesn't hear as well as it used to, according to users. I am not
concerned about losing a couple dB on the TX side. I am hoping, though,
that a re-tuning will decrease the de-sensing and, perhaps, add a slight
increase in sensitivity.

 

The system does have a pre-amp that appears to give about 4 dB of gain. 

 

I look forward to your suggestions.

 

John

Is the duplexer not meeting its loss or isolation specs?

Re: Re: [Repeater-Builder ] Re: RadioShack Recalls P ower Supplies Due toElec trocution and Fire Hazards

[Ron Wright]

I believe RS has to take the supply back and rewire or fix it.  It sounds like 
an easy thing to do...just reverse the neutral and safety ground as the plug 
enters the supply.

If I had a number of these I would take back to RS and have them do it.  They 
should put a label on it stating the mod had been done.

I wonder if there are any charges such as return shipping charges.

Although one can say if your outlet is wire correctly there would not be a 
problem.  This is true, but with the millions of outlets in the world and maybe 
one in your own home you have not yet tried with the RS supply I would 
definitly want it wired correctly.

I wonder how this happened.  I am sure the supply is UL listed (no such thing 
as US approved) so looks like something got over looked or a change occured at 
RS manufacturing.

In the US the safety ground and neutral both go back to the same place in the 
power panel (fuse box).  Most of the time both are insulated with different 
color wires and often the neutral is a size larger wire (not allowed with new 
code), but with the RS supply this wire size would not be a problem.

I must have a half-dozen of these

true, they will NOT show ground/neutral reversal, but if your panel is wired

  My brother lived in a house with two wire plugs he changed to three wire
  plugs. He just jumpered the neutral and ground together on the plugs.

  It fooled the inspector with the little plug in light up gizmo.

  I highly recomend one of these to anyone working around electricity.

Yes there is a new version available from Fluke.
I have one as well as two of the older versions.
One is in my shirt pocket at all times !
If you ever tried to check a dead string of Christmas tree lights, then this 
thing is what you need.
It will show you where the bad bulb is located by not lighting up past the 
bulb.
If you check an outlet and see power on both the hot and the neutral, then 
the ground is missing.
They are very handy in checking a power panel to find the open breaker, or a 
blown glass fuse.

These are one of the best and simplest AC testers ever built.
