That doesn't look too bad to me.

0.3% is good enough and better than most for TCP. However, you should
run Skype Echo Test or talk with someone using Skype first, and then
check the UDP, not the TCP statistics. VoIP (and video) are both UDP,
not TCP.

Have to do that, but IIRC those numbers looked comparably good. I do not
think it's any packet error issue. It is very repeatable. Skype with
camera video works and the instant I switch to screen sharing it falls
apart. So we have resorted to low-tech, sketching stuff on paper and
holding it up to the camera. Then Skype doesn't fail. My Logitech camera
isn't very good though, no dynamic range to write home about, very
grainy picture because I am sitting with the back to a window.

Right click on the Windoze "Task Bar" (bottom of screen) and select
"Task Manager". Click on the "Networking" tab. Not the best monitor
but it should give you a clue as to the total network traffic.

I've used that sometimes but it doesn't really tell you how close things
are to a limit on the DSL side. It only reads a percentage, whatever
that means.

It's the percentage of your ethernet bandwidth. If you have a
100Mbit/sec ethernet connection to your router, and your DSL is
running at 1.5Mbits/sec, you'll see a tiny 1.5% maximum display on the
graph. This piece of brilliant design was brought to you by the
wonderful folks at Microsoft.

Shazam! They were quite smart then.

Parallel ports are so 20th century. Kinda sounds like an old router,
which may be the cause of the slow speeds. I've replaced various
Netgear WGR614 series routers that seemed to slow down after about 5
years in service. No failures, just a slow down. No clue what that
was about, but replacing the router with something more current made a
big difference. You might also look into the benefits of ethernet
connected laser printers. Incidentally, the typical complaint was not
VoIP problems but rather problems streaming YouTube and Netflix
videos.

Well, I tend to keep stuff that works regardless of how "modern" it is.
This old HP-5L is around 15 years old but keeps on humming. So I need LPT.

Other than Skype everything runs fine. Skype has had other problems in
the beginning but that got fixed when they released a newer version. The
screen sharing never worked right.

Also, QoS probably won't
help much because when I use Skype there is typically nobody else using
the Internet here. So all the available bandwidth is available to Skype.

It will help when you're transferring files at the same time that
you're talking on Skype or reading something on the internet at the
same time.

I never do that unless someone requests it during the call, and then we
all know it's going to come at the price of a rocky link. Until I can
get faster Internet. The amazing thing is, GoToMeeting will then slow
down the video but screen sharing keeps working. Because if implemented
correctly that really doesn't need any bandwidth to speak of if a static
drawing where only a cursor is moving. Same for the "etch-a-sketch"
function.

I think you mean the FCC ASR (Antenna Structure Registration).
http://wireless.fcc.gov/geographic/index.htm?job=licensing_database_extracts
Only towers that are over 200ft or are near an airport need to be
registered:
http://www.fcc.gov/help/antenna-structure-registration-asr-help
Few cell towers are over 200ft.

More:
http://www.towermaps.com/fcc.htm
Note that most cell sites are NOT registered with the FCC. If you
believe the CTIA, there are 300,000 cell sites in the USA:
http://www.ctia.org/advocacy/research/index.cfm/aid/10323
However, that doesn't include repeaters, microcellular, DAS
(distributed antenna systems), Small Cells, leaky coax in tunnels,
water towers, church steeples, and many building mounted sites that do
not involve a tower.

No, that's not it. This site had all cell towers listed, including
church steeples. ;-) The information included latitude longitude,
owner, network, and a bunch of other stuff.

Would be nice if you remembered that link. Because everything I tried
before getting my cell phone was incomplete as Jeff said. Since the guys
at the telco couldn't tell me either I literally drove down to where I
remembered was a collection cell antennas on a pole. Couldn't say which
companies were on there. Why don't they list that _on_ the pole? So I
asked around until I found someone on the Sprint network to see if he
gets full bars on that stretch of road. He did, so I knew I can make
this work from my lab. Sounds pathetic, but that was the only way.

Now that I have a very portable spectrum analyzer (Signalhound) I could
have found out immediately by driving there.

Yep. I have leaked data on tower locations from specific providers
and from the county planning department, but that goes obsolete every
few months. Cell sites are proposed, and dropped. Cell sites are
moved. Cell sites are replaced by DAS systems. I can barely keep up
with the local sites, and I suspect that the FCC would not be able to
do the same.

Because everything I tried
before getting my cell phone was incomplete as Jeff said.

The way it works is that FCC auctions the frequency and service by
market area. The auction winner and service provider can put as many
cell sites and they see fit to install within their authorized market
area. No need to register or license each radio with the FCC. When
cell sites were all located on towers, it was easy to find them in the
FAA ASR list. Today, with small cellular being a popular way to
circumvent local zoning hassles, the sites are no longer listed.

<http://802.11junk.com/jeffl/pics/office/slides/office-mess-02.html>
See the map on the wall at the right of the photo. That's the Cell
One map for Santa Cruz circa about 1998.

<http://802.11junk.com/cellular/Wireless-Cell-Sites.jpg>
That's a photo of the local cell sites circa 2002 from the county
planning department. They refused to give me a copy, so I had to

Many cell sites are sufficiently disguised that visual identification
is impossible.

You can sorta guess by the frequencies that are being used. I found a

Not required by FCC, PUC, or any other manufacturer of rules and

Careful. Sprint and Verizon roam into each others territories. Full
bars on one provider could be an indication of roaming into the other.
Check the roaming indicator.

If you want more detail, dive into the "field test mode" for the cell
phone to get the carrier and tower ID.

Ok, XP arrived 12 years ago, so I can't really complain (much).

The XP Task Manager wasn't really intended to do traffic monitoring.
For that, Microsoft provides the Performance Monitor.

Under "performance object" pick something interesting to graph, such

Don't say that. It's bad for the repair business. I'm certain that
if you look carefully, you can find something which needs fixing.

In about 2003, when I doing the local cell site maps, I announced that
I was going to organize a tour of the local cell sites. It was
intended as a joke, since I assumed that nobody would be interested.
About 20 people were interested enough to ask for schedules and fees.
However, in exchanging email, I found that none were particularly
technical. It took a while to determine what was happening. They
were into Orgonite and cell tower "gifting" in order to magically
detoxify the RF. I was expected to drive them around to the various
cell sites, where they would perform the "gifting" ritual.

There's a house going up across the valley, phone line is in a trench

below surfcae or less. Often exposed in the ditch.

To me this is a day and night difference. A new neighbor learned this as
well. The cable guys couldn't get his Internet going for over a month so
he took the slower DSL.

Git 'r done!

Sounds like he lives in 'Green Acres' and tried to use the
Hooterville TV & Bait Shop.

That's good, right? No engine problems. (just kidding)

Here's the only schematic I can find that shows the transistor and resistor on the board, but no info as to what the parts are. Also, can't find what is connected to the base, and can't get in to check the base signal.

If you can't get to the base of the transistor, how can you expect to replace it? Can you just solder a wire to the transistor? The point is to check if there are switching voltage, and what it is.

What is the size of the transistor? TO-92, TO-220?

I would suggest 13001 and 13003 respectively. These have huge break-down voltage, 600V and 400V. You might not need it, but won't hurt to have it.

Looking for the simplest way to this.

AC powered 9V wall-wart or 9V battery powering a circuit.
9V battery is alkaline so is not charged by 9V AC supply.
Load is < 50 ma.

When AC is on, power from the AC to 9v PS.
AC off, power from 9V battery.
9V battery only supplies power when 9V AC is off.

The catch: the 9V AC PS output may be lower than the 9V battery or
visa versa.

So a simple two diode scheme will not fly.
Minimum parts and no relays.
Suggestions please.

From a previous SED thread, where an unregulated wall-wart was
involved...


<http://www.analog-innovations.com/SED/PowerSwitching_Battery-Wallwart.pdf>

If I understand your situation correctly, it might be as simple as
using a barrel connector with a built-in switch (from R/S, as I
remember buying them)...

<http://www.analog-innovations.com/SED/PowerSwitching_OldGuy.pdf>

If you have a more complex situation, like wall-wart hard-wired in
place, I have other solutions to detect that it's live and switch
accordingly.
