If it is the government it doesn't need a tap! They can/do record your
conversations right off the phone company's computer using a court order
(or not!). If you have a tap (Pvt.I.) it implies the information is
transmitted elsewhere and a "sniffer" will find the radio emissions.
However, the tap is more likely to be at the junction box down the
street or up on the pole where no b&e is required. Good luck.

Man you got my interest here. Are you saying they make a portable
phone with two units so you could both talk at the same time off of
it? If so, does it have a "find it" type ringer so the other person
would know you want them?

My wife and I both carry portable phones and walkie talkies during our
strawberry season. Phones for customers and walkie talkies to pass
messages between us. I'm in the field, she runs the counter. Pain in
the but to talk on both at the same time. It would be major handy to
have one unit do both.

For our application, we prefer cheap 2.4 gig phones. Range is well
over 1/8 mile unless a steel building is in the way. We got four units
on closeout for $40 each. My number one tuff requirement is a belt
clip and this is always the first thing to break.

The industry is dying, and any tech that tells you otherwise is either
incredibly naive or has a few bats in his/her belfry

I'm not in the repair business but do my share of it for fun. The "industry"
died a long time ago.
As the OP mentioned most consumer electronics is throw away garbage now. When
you can buy a new TV, VCR etc for $50 its not worth fixing. Its common sense

The complexity of todays junk is such that there are no longer any experts or
quick easy fixes (I'm sure there are some known common problems with certain
models that are easy). You need detailed service information to make heads or
tails out of anything. Service information cost money. Even armed with the
proper info its still more time consuming than most of the stuff is worth.Years
ago if you had the schematic of a television, radio, CB Radio etc it pretty
much covered hundreds of other models.

I would not even know where to find an electronics repair outfit in my area. At
one time they were on every street corner. All disappeared. Same goes for all
the small electronic distributors where you could walk in and buy a single
tube, transistor, IC or resistor and not have someone roll their eyes or
explain about the $50 minimum purchase. Same goes for Radio Shack. Unless its a
toy its not stocked and its special order. Forget parts.

Its all downhill from here. The human thirst for products with mostly useless
complex bells and whistles for the sole purpose of showing them off to their
friends will never die.

Technologically we are really good at all the wrong things. Like spending
millions on product testing to insure that it only lasts a short time or a
specified amount of time for warranty purposes. Now theres an exact science.

Why repair something thats really nothing more than a toy, incredibly complex
and designed to fail?

Have to agree with Robin, Loren. Stay at 900 or, if compelled to
move, go to 5.4.

I believe the FCC finally approved Amateur Radio as the primary user
of th elower half of 2.4 - effectively wiping out channels 1-6. There
may not be any interferrence now, but should there be any, the FCC
would issue the cease and desist letter to you. the high band is also
shared with others, including amateurs and may face the same fate in
the future.

The quality of the repair suggestions that you will obtain on the newsgroup
is totally dependent on the information that you provide in your original
post. If you include basic technical troubleshooting data, voltage
measurements, component testing results, visual inspection results, etc,
etc..... you may get some specific troubleshooting hints.....
......on the other hand if you post virtually NOTHING, you will more than
likely receive virtually NOTHING.
You may want to go to the website for this newsgroup at
http://www.repairfaq.org/
There, with some search time, you will find a wealth of troubleshooting
tips, repair procedures, component testing methods and IMPORTANT safety
information that will help you stay away from dangerous and lethal
electrical shock hazards inside your television..... note that these hazards
may still be present even when the television is turned off and unplugged
from the AC power.... be very careful.
If, after reading through the repairfaq, you are still not certain how to
proceed you might be best advised to take your television to a service shop
for a proper and safe repair.... or at the very least, obtain a repair cost
estimate so you can make an intelligent repair decision with facts instead
of internet wild guesses.
....... and yes, probably all the "poor resistors" need to be replaced.

[bigmike]

Hi Doug. I start out tinkering with electronics in my fathers shop back in
the early 1960s, and have been doing it ever since. I am lucky in the fact
that I am also a musician, and I started playing piano at age 6, and I get
to enjoy both professions, and they compliment each other.

My father sold the first TV in the town I grew up in over in Iowa. Like Dan,
I was heavy into Ham radio as a kid, and building anything and everything I
could afford to buy the part for. I worked with my father, while going to
college. After he retired, I took an offer to run one of the largest shops
in the midwest. I did this for several years, and finally decided to open my
own shop, which I did, and have been running it 25 years now. While working
in electronics, I also started playing piano in a country band back in the
80s, and we recorded a single that made it in into the top 40s on the
country charts. I found myself traveling all over the country to promote the
album, which never went any further However, it did give me the chance to
work as a session musician for many different artist, and to play with many
famous artist of the time, such as Merle Hagard, the Statler Brothers, and
Crystal Gale. So for a few years, I had a detour from electronics, until I
opened my own shop. So for the past 25 years, I have ran a shop during the
day, and played keyboards with several local bands on the weekends. I am now
getting ready to retire, because I have a degenerative desease that is
destroying the nerves in my lower back, and I have to use a walker to get
around now. My sons help me lift sets, but they have lives of their own to
live. While it hurts to have to close the shop, I will still stay active in
the electronics field, and I will now devote more time to music, because I
built a small studio in my house, and I want to go back to composing and
recording my own music. That was probably more than anybody wanted to hear,
but since my electronic profession is nearing an end after 40 years, what
the hell

As far as electronic repair goes nowadays, by all means, it has changed. We
use to have 3 electronic parts suppliers in the town I live in, now we have
none. The days of grabbing a couple of caddies and fixing most sets in the
home is over for many techs, especially independent ones. It seems obvious
that the day of the crt is nearing the end, since so much time and money is
being put into research for a better alternative. When they do away with the
HV stage in most sets, that will greatly increase the reliability of TVs.
Less heat, lower voltage and current requirements, and a lower number of
components will be the main reasons. I do feel sorry for those just coming
into the business, because it has changed so much, that even though it is
still fun to a degree, it's nothing like it use to be, at least not for me.
And since many homes will probably have huge widescreen HDTVs in them in the
near future, those will not be something fun to haul into the shop, so I
have no idea what direction that will take the serviceman. You better have a
lot of parts/boards/schematics and test equipment on hand is all I can guess


As far as relatives and friends wanting free or discount service, it goes
with the job. I don't mind doing repairs for my relatives, because most of
them offer to pay something for my time. I usually say no, except when the
parts are expensive. As far as friends go, it depends on how good a friend
they are Everybodys your friend when they need something from you. I just
usually tell them they are getting a good deal, whether they are or not

One big problem anymore is that fact that people are starting to have the
frame of mind that nothing they buy is going to last more than a few years.
So this makes them think about tossing many items that could be fixed. At
the same time, who can blame them though, when the cost of repair can be not
much different then buying new. Even when it's not, many people will think
their money is wasted on repair, since the unit will not run long enough to
make it worth the expense.

What I really miss about electronics, is all the electronic publications
that are no more. I always enjoyed building and experimenting with
electronics. It was a great hobby to have along side with repairing. I have
a lot of test equipment that I built over the years, that I still use today.
I have amps and preamps and effect units that I built, that I still use in
my music.

Shops are going to have to make some hard calls in the next few years about
what test equipment and parts to carry to service the newer sets. It's not
going to be cheap, and it's going to be hard for the independent techs to
compete with the factory authorized dealerships.

Anyway, that's it for me. Thanks for your input and asking for others
opinions.

Hi everyone...
I will start this post with a great Thank You to all who
have taken their time to post and share their knowledge
in this forum. It's been great reading your posts!

Now, I would like to share my opinion on doing repairs on
consumer electronics.
It's seems to me that as soon as someone finds out you are
into electronics, they have a light bulb goes on in their
head... POP.... Hey!... FREE electronic servicing.
Friends and so called acquaintances and co-workers dump
all kinds of broken electronic crap at your feet expecting
instant FREE service.
When you are not thrilled at the prospect, they may offer
to actually pay up to $10 for the parts.
What is it with people.
Are we all just a bunch of cheap skates,
tight-wads, and skin flints, trying to manipulate or leverage
our relationships and friendships to see how much we
can exploit others for our own benefit.
People are delusional, when it comes to servicing electronic
appliances etc.

I usually like to tell them that their article is made in the
3rd world like Indonesia, china, Taiwan or Mexico where people
work for as low as $1.20 a day. Maybe they could ship their
broken TV or VCR or stereo to China for servicing as people in
North America want at least $20-$60 a hour. (joke)

Ah! maybe I'm too cynical.....

All that aside, I still like tinkering in Electronics for fun.
But, to hell with servicing for profit, it's a non-starter.
Vendors are impossible to deal with, they hoard information,
charge ridiculous prices for their parts (if they have them),
Use non standard fittings and fasteners, anything just to foil
you up. The whole industry is set up to re-inforce the
"throw away when broken" mentality of our consumer society.

P.S. A note to Daniel Sofie....

Thanks for your great input here....
and you are right to suggest to unskilled hobbyist's to
take their gear in for professionel servicing.
People underestimate the complexity of electronic gear,
it's like they assume its about as simple as a light switch.
Ever heard this one before.."It's probably just the fuse"

One good thing the EU and/or UK govt. could do is to pass a law to
*require* all electronic equipment to be recycled down to the nuts and
bolts . All new equipment sold has a 10% sales tax added to pay for
proper recycling facilities , *with the tax cut to 2% if it is
specifically designed to be repairable and recyclable* .

In addition, any company that repairs consumer equipment should be
able to apply for a grant to cover running costs etc . Should keep

the standards of the consumer electronics industry. The ONLY rational for
not putting one in (or some other method of protection) is, to put it
bluntly, screw whoever dares use a non-original manufacturer adapter that
might cost 1/10th of the original replacement.

What about that Dell ATX power supply pinout affair a few years ago?

Remind me never to buy a Dell machine, ever again . Or Compaq . (more
non standard mucho mega$$$ power supplies, that blow up at the drop of

Whoever came up with that little ploy should be sat in a room , and
made to repair every single computer they caused to be destroyed .

Reverse polarity protection should be a standard feature required by
the CE regulations .

Please find a hole in my logic.

There's always more than one way to look at something. I don't think a
manufacturer should have to protect the end user from their own
stupidity. As was pointed out, it didn't burn the guy's house down

Typically it's just the power supply that gets UL approval, not the
printer.
That may be the main reason a lot of manufacturers use external wall
type
power supplies instead of building it in. They don't have to submit
the
product for safety testing.

Thanks for staying on topic. It makes a lot of sense to do this.
Especially if a company would use one adapter for several models of
its products. This is hardly the case with the company in question.
Voltages vary, prong polarity is inconsistent.

I'm not all that happy with the Epson solution, since we're talking
printers. Their 110 VAC power cord is permanently attached to the
box. Give that designer a star Most likely cheaper than
providing a detachable power cord.

Interesting .

Power supply problems, most likely. Bad caps, and/or undersize power

resistors that char the circuit board in those sets, and no longer make

Spread spectrum technology was originally used by the military. It involves
a frequency-division-type multiplex system, i.e. the transmission switches
frequencies across a spectrum of channels at a high speed during the call.
This increases privacy, because those listening to one frequency only, e.g.
with a scanner, won't hear the conversation, and reduces the susceptibility
to interference or jamming.
