It would be helpful if the OP would give a city or zip code where they
live.
 
Here in Chicago, the local "channel 2" I beleive is still on a vhf channel.
 
They are digital 2 and 2.1 but the transmitter is either on the old channel
7 or 13.
 
People who install those uhf only antennas find out about that the hard way.
 
So it's possible the vhf side of the tuner failed or the outside antenna got
damaged somehow, the vhf channels would be the longer/longest elements.

** But the OP claims he has TWO sets on the same antenna - one of which is 100% OK.
 
That's gotta be a set fault.

Does your neighbor still get those channels?
Maybe there not transmitting.

In Chicago, WBBM 2.1 and 2.2 are now duplicated on WMEU 48.3 and 48.4.
That was probably done due to issues with them being on RF12 (VHF Hi)
and many people using antennas that are UHF only. WMEU is a low-power
Class D station, but it transmits from the Willis (Sears) tower and has
pretty good range.

Hey Phil I think that's a new line, good on you.
Ya, I missed her line, "Next thing I did was to swap the cable
connections at each TV."
So she has other TVs that receive channel 2.x.
When a newsgroup produces so much ire in you life, why do you keep
reading? Or is being pissed off all the time, just your life's excitement?

Sounds like a computer controlled carburated engine. Those were a bad marriage. When they finally got to fuel injection it was much better. Seems like GM was the first, while others stuck with the clunky barbs with the enrichment solenoid. A pure mess really.

Hah, mee too. But around here in the winter they use a lot of salt...
and I guess that just brings the ground closer... (I'm happy
if I get 200k.) I buy little commuter cars, and just can't find many
with a stick... so my last two cars have been auto.
I down shift going down my hill, but that's about it.

2009 date but no PbF statement anywhere seen.
Strange protect cct, +140V on the red supply and +65V on the black,
continuity to +ve of the main bridge rect, but not for the -ve tab.
Time to take the amp apart to get to the othe rside of the ps board, no
obvious failings there topside. For the moment the smokey staining above
one of the 4 TOP66 I'll take to mean it was taking more than its fair
share of the remaining 3 after the base resistor failed on one of the 4.

No, they are Amish. Almost all my neighbors are Amish, except for one
very old retired farmer who I doubt even knows what the internet is.

I can not see it from my rooftop. There is a woods between my house and
the road. But even without the trees, I could not see the town, unless I
drive to the top of the hill (I live in a valley). My land ends at
almost the top of the hill, and I can probably see the town if I was to
climb a tree, or even stand on top of a full hay wagon full of hay. But
if I go another 50 or 70 feet higher (up the private road), I can easily
see town. (If this is not making sense, my driveway is a shared private
road. Between the county road and my farm, there is cropland. The
driveway is shared by myself and the farmer who owns that land. (He does
not live there, it's just crops). This roadway (driveway) is 2/3 of a
mile from the county road to my house. [and, yea, I have to plow the
whole friggin thing when it snows].
 
Yes, that town has high speed internet, and has public WIFI at the
library and at a fast food restaurant. As well as a lot of secured WIFI
signals (at businesses) that I can see on my laptop, when I am in town.
I regularly sit in the parking lot at that restaurant and use the WIFI
from my car, even when they are closed.
 
You lost me, when you started talking about "point to point wireless
link, and WISP".

I was looking at those cellphone boosters on ebay. Since I can get a
semi-usable signal on the roof, I thought about putting a yagi antenna
on my tv antenna tower and running that into the house. Part of my
problem is having a house with metal siding and roof.

Getting my Amish neighbors involved is not gonna happen :)
 
But I did sign a petition to get better cell service, after I raised
hell with some of the law enforcement people in the area. This occurred
about 20 months ago, when I saw a building on fire in another small town
nearby. I had a vehicle breakdown, and I was unable to call anyone for
help, because there is no cell signal at all in that town. So, while I'm
trying to fix my truck in cold weather, I notice a building on fire a
block away, and I cant even call the fire dept. This was during the
night, that town consists of about 100 population and no one drives up
that town's roads during the night. I finally woke someone up by banging
on doors, but by the time they called the fire dept, that building was a
total loss.
 
After I bitched like hell to the fire dept and other law enforcement,
that petition was created. It was passed around that town and other
nearby small towns. It was at the bars and public buildings, and got
around 250 signatures. The cell company in the area said they were
planning to build a new tower. (But from what I have heard from the
locals, they said that same thing 10 years ago). Nothing has changed.

I hate having to cope with dialup, and worse yet, I can not establish a
decent connection using my US RObotics modem on any computer with
Windows XP. I can only connect using Window 98. I dont mind Win98, in
fact I like it, but the newest browser I can use if Firefox 3.x. At
least half the websites no longer work for me. So I mostly just use
usenet and email most of the time now, but some websites still work. If
they dont load after 10 minutes, I know they will never load.
 
I may be emailing you soon....

The rotor is probably denser than the wheels, it might dominate.
One quick way to test a 400uF 330VAC capacitor, would be
to put a smaller known-good capacitor in parallel with it. If that
makes a big difference, the old capacitor needs replacement.
 
Look for a date on the capacitor (and if you replace it, write a date on
the new one); tracking the history sometimes simplifies things.
