That's normal maintenance.

You use Turnpike. I've never tried it and know nothing about. Might it
send an e-mail reply rather than a newsgroup reply without your

If that's not exactly right, it's very close. I've also seen her
messages, in another newsgroup.
 
But she's inviting people to reply by e-mail, and with a very
occasional exception, I don't want to do that.

No, of course not. It's only for newsgroups.

I'm almost 82. When I was a lot younger, I used to like to repair some
things, if I could. But I was generally poor at fixing most things.

I might not have succeeded, but that's the kind of thing I might have
tried to fix. I would have suspected lint, and if my suspicion was
right, fixing it would probably have been easy. And worst case, if I
failed, I'd just buy him a new one.

I think you probably would have succeeded, It was fairly straight
forward (no loose parts flying everywhere), Don't undersell yourself,
I'm 85 and can still do it.

We're almost the same age. I'm about to turn 82. But my thought that I
might not succeed is not based on my age. I've never been good at
working with my hands.

Well, never without my choosing; in theory I could accidentally send the
wrong one (the Followup and Reply buttons are adjacent), but I don't
think I've actually done that in several decades of using it. What it
won't do is send _both_ at once, as its designers felt strongly about
that - irritating as I _occasionally_ _want_ to.

Well, s/he's not exactly inviting, just pointing out that if you _do_

The buttons are adjacent here too. I've occasionally done it
accidentally, but I've always caught it and fixed it before I pressed
Send. I use Outlook e-mail, not Agent's, so the Windows look very
different.

I suppose it's technically not an invitation, but to me, telling the
reader how to do it is so close to an invitation that I have no
problem with calling it that.
 
It's sort of like, "If you want to send me a check, my address is ..."

Hi Paul,
 
Here are more pictures of that IBM mouse, which I'm still using now that I
refurbished it (although I had to glue a side stick on it to keep my
fingers away from the right mouse button since it's a poor design for huge
hands like I happen to have).
 
Anyway, here are the pictures I took when I disassembled it:

<https://i.postimg.cc/3whH5J4v/mouse05.jpg>
<https://i.postimg.cc/fTXw6P21/mouse06.jpg>
 
The tilted LED simply lights up the middle mouse button (AFAICR).
 
If you want, I can snap a photo of the side stick I glued on to make it
less error prone, where I learned that it's critical for a mouse to have a
landing space for your right-mouse finger to "rest" without being too close
ot the right mouse button itself.

Hi Paul,
 
As you're aware, this isn't my first rodeo with trolls on Usenet,
where, tactically, I respond as a mirror to their implied intent.
 
Generally you are purposefully helpful, as am I.
o So I won't quibble about your answer (as it was a fair guess).
 
In addition, I will try to add technical value, as you tried to do.
o Since I act as a mirror to perceived implied intentions.
 
For that photo <https://i.postimg.cc/cHLndnbY/antenna.jpg>
o That antenna was bought a decade ago, but it's similar to these:
<https://www.streakwave.com/items.asp?Cc=ANT2%2E4FP>
Where, a fair modern comparison, might be this $35 15dBi antenna:
<https://www.streakwave.com/itemdesc.asp?ic=15-537>
With the spec sheet as shown here:
<https://www.streakwave.com/mmSWAVE1/Video/15-537.pdf>
 
That antenna is simply connected to my router inside the house, which then
beams 2.4GHz Wi-Fi signal at up to 600mW (about 27 dBi)
<https://www.rapidtables.com/convert/power/mW_to_dBm.html>
via this $80 radio attached directly to the back of that antenna:
<https://www.streakwave.com/itemdesc.asp?ic=BulletM2HP-US>
 
Note that for about the price of a typical SOHO router of about 15 to 20
decibels, this access point allows up to 27 dBi + 15 dBm = 42 dB, which is
vastly more powerful than any typical SOHO router access point you've ever
experienced in your entire life, I'd wager.
 
I repeat what the trolls accused me of not understanding, which they
themselves simply fabricated, which is that every 10 decibels is 10 times
the power so for there to be that many decibels difference, is huge, at
about the price as your normal consumer equipment is at the box stores.
 
Of course, this stuff isn't sold in the box stores, most likely, so you
have to simply KNOW about this stuff, which was, partly, the intention of
this purposefully helpful thread.
 
Bear in mind, the radio is always attached directly to the back of that
antenna, as is the radio attached directly to the back of this 2.4GHz Wi-Fi
antenna in my house right now.
<https://i.postimg.cc/nrkz5mgs/antenna01.jpg>
 
Likewise, the radio is attached directly to this 5GHz Wi-Fi antenna, Paul:
<https://i.postimg.cc/yNXw0TZS/antenna02.jpg>
 
Perhaps most importantly, this 2.4GHz WiFi radio is physically a part of
the antenna - which means you can't possibly separate the two - they're one
unit - which - of course - is why we refer to such things, colloquially -
as "aim the antenna" will ya...
<https://i.postimg.cc/CLBXc080/antenna03.jpg>
 
Please look at that latter situation, Paul.
 
If you remove the radio - the "dish" has a huge hole in it that does
nothing, since the "horn" is on the radio, and not on the parabolic dish.
 
The point is that the radio and the antenna are considered a single unit
(and, in fact, are only sold as a single unit), just as when you buy a new
car, the tires and wheels are sold as a single unit.
 
And, more importantly when you're trying to help people get stuff done,
when I write a tutorial for how to mount your tires at home:
<https://i.postimg.cc/WzZW9MvT/mount07.jpg>
You can assume, a priori, that everyone is well aware SUV tires & wheels
are different, but they are always directly attached to each other.
 
Just as when I write a tutorial for how to balance your tires at home,
<https://i.postimg.cc/28JK2bFB/mount58.jpg>
You can assume, a priori, that everyone is well aware SUV tires & wheels
are different, but they are always directly attached to each other.
 
The fact I'm trying to explain, is what you try to write something like a
o Tutorial for how to balance your SUV tires at home
o Tutorial for how to aim your WiFi antenna at home
All you should need to do is mention just once that when we say
o "mount the tires",
it's assumed intelligent adults know SUV tires are directly attached to wheels
Just as when we say:
o "aim the antenna",
it's assumed intelligent adults know WiFi radios are directly attached to antennas

Typo.
 
Since the trolls here can't everv add value, but can quibble about
meaningless typos like squabbling little girls, that was dBm, not dBi...
 
Likewise, with this typo...
 
> Note that for about the price of a typical SOHO router of about 15 to 20

Reverse the "i" with the "m" ... and add "EIRP", where this correction is
necessary becuase the child-like trolls will have a field day over a typo -
since they can't actually add on-topic technical value...
 
> just as when you buy a new car, the tires and wheels are sold as a single unit.
 
More correctly, since the trolls will have a field day noting there are
four of them, let's just say the wheels, tires, and car, are sold as a
single unit.... to keep the moronic trolls at bay ... because they can't
actually contribute on-topic technical value - so they quibble like
schoolgirls instead.

Yikes. In addition to the "dBi" and "dBm" thinkos...
<https://i.postimg.cc/DZccY2YD/decibels.jpg>
 
There was, in the sig, yet another typo ... "impedance" (not imedence")...
 
Note the main reason for having to correct the typos is that those silly
little girls on this newsgroup who have nothing to add, will endlessly
quibble about the typos just like you see happening in this thread about
"antenna" versus "radio", where, this set in my basement shows the antenna
and radio can be considered one unit for practical purposes such as the
instruction "aim the antenna, will ya".
<https://i.postimg.cc/XJChDCPr/spare-access-points.jpg>
 
As I noted with tires, those who quibble about the colloquial use of
something as common as decibels would never get to the more important
points, such as where we discuss in a tutorial how to mount the red dot
<https://i.postimg.cc/Pqq6GGj6/mount09.jpg>
versus what's different when we choose how to mount the yellow dot:
<<https://i.postimg.cc/4yxSFpSp/mount57.jpg>
 
Where the main point is that if we're trying to get something done,
then quibbling about the fact that tires and wheels are different is
something only those who have zero value to add, will quibble about.
 
Sure, those trolls are MOST of the posts in this thread.
o But the fact remains the trolls added _zero_ on topic technical value.
 
Having said that, almost always, the Wi-Fi radios we're talking about are
mounted directly to the antenna (just as SUV tires are mounted directly to
the wheels), there are cases when the Wi-Fi radio is simply "close" to the
antenna, as shown in this box I built myself a few years ago out of spare
parts:
<https://i.postimg.cc/DfQJq437/mikrotikrouter.jpg>
 
In that case, the radio is "close" to the antenna, as shown in this picture
which shows that the old desktop can be placed hundreds of feet from the
house in the barn, and it will still connect either to the access points
scattered about the property...
<https://i.postimg.cc/Gh22Sb2N/desktop.jpg>
Or, if needed, it can connect to access points literally miles away.

Hi Johann Beretta,
 
Here's a shot of the barn desktop which shows that setup better:
<https://i.postimg.cc/6QJqK6Cj/desktop02.jpg>
 
Notice that barn desktop has no WiFi card; it only has Ethernet.
 
And yet, it's connected by WiFi using this Mikrotik equipment:
<https://i.postimg.cc/yx4CgWYt/mikrotik-router-config.jpg>
 
Is that barn desktop connected to Wi-Fi over its Ethernet, or not?

You are astute enough to be worth further detail, as you know what you're
talking about (while others don't, so I simplified things for them).
 
For you, we can dive directly into the actual unexemplified details.
o Here is a more explicitly detailed set of pictures & screenshots & specs.
 
My desktop, at this very moment, doesn't even have built-in Wi-Fi, but it
does have built-in Ethernet (and yes, I'm using that term colloquially).
<https://i.postimg.cc/6QJqK6Cj/desktop02.jpg>
 
This is a shot of the radio configuration that Ethernet is tied to:
<https://i.postimg.cc/DfQJq437/mikrotikrouter.jpg>
 
The CAT5 out of the desktop connects to a $50 Mikrotik routerboard
<https://mikrotik.com/product/RB411>
o 300MHz CPU, 32MB RAM, 1xEthernet, miniPCI, serial port, RouterOS L3

With a 23dBm $50 card plugged into the routerboard's miniPCI slot
<https://mikrotik.com/product/R52NM>
o 2.4/5Ghz miniPCI 802.11a/b/g/n dual chain, 2x MMCX
 
Whose output is attached to a 15dBi $40 2.4GHz wiregrid antenna:
<https://www.streakwave.com/itemdesc.asp?ic=GD24-15-NM>
 
Where the signal strength, at this very moment, is about
-40dBm with a Tx/Rx CCQ of about 80%, S/N of about 75dB.
<https://i.postimg.cc/yx4CgWYt/mikrotik-router-config.jpg>
 
Does this detailed setup look more like what you were expecting to see?

If you only knew how many access points I can 'see', you'd be shocked
(I guess the theoretical number could perhaps be in the millions, in fact,
depending on antenna gain & radio sensitivity & noise floor on my side of
course, but I never counted them ... suffice to say it's a LOT).

Then you are using Google. Duck Duck Go uses Google to do the heavy lifting, then they display it as if it was their own. The only thing the contribute are filters for the results from Google.

Having worked on tube gear for well over 50 years, YES, you need a tube
tester, unless you want to stock replacement tubes for everything you
work on (not very practical). But you want a good quality tester. They
used to actually sell tube testers that did nothing but check if the
filament worked. Very useless. If the filament lights in the radio, the
filament works. Or use an ohm meter.
 
Back in my youth, drug stores had tube testers. Some did a halfway good
test, while others were pretty useless. But it gave you something to do
while the pharmacist spent an hour putting 20 pills in a bottle. Then
you went home, took your drugs and got too stoned to remember which tube
was the bad one. :)
 
I have three tube testers. All are very old. Yet they still work well.
The biggest problem with all of them are the paper roll charts. They
fall apart from age. Most of the data on them is available online. You
can either spend a lot of time making your own roll chart, or just print
individual sheets, punch holes, and put then in a notebook.
 
Buying an old RCA or GE or other brand tube manual is needed too. Or you
can now download them for free in .PDF format. Search for "RCA tube
manual" or similar.

** The OP is not going into the servicing business.
 
He has exactly one, old tube radio with no clue how to work on it.
 
A tube tester is the LAST thing he needs to spend money on.

Confusing post. Are you referring to the physical moving hand meter
itself, or are you referring to the whole box?
 
If the meter shows the full scale sensitivity somewhere on the face, you
can compute the resistance necessary to put in series with a 1.5 volt
battery and correctly apply the + and - to the meter movement and see if
it moves.
 
Alternately, put a 10k ohm resistor in series with your Ohmmeter leads
and test the combined resistance to see if you get 10k Ohms. If so, then
the meter is ok.

Since we are commenting on CB use. I too am glad all the kids and idiots
are gone on the CB Band. These days they're all on facebook instead.
I do tend to not understand what happened to all the truckers on the CB?
Channel 9 is really no longer needed. For emergencies, people can just
use their cellphone to call for help now. But truckers cant get instant
road conditions up ahead, or smokey reports on their phones. And you
cant talk to other truckers near you (unless you know all of them and
have their phone numbers). So for truckers or anyone on the road, the CB
still has a lot to offer. Not to mention its against the law to use a
cellphone while driving in many places now. But not the CB.
 
Two things I hope to never hear on the CB again are those annoying Roger
Beeps, and the echo mics. Neither served any purpose and just made the
CB hard to hear or worse.
 
One other benefit of CB was that a lot of times in the past, I'd just
talk on the CB to keep myself awake while driving late at night. And I
had a lot of interesting conversations, as well as finding out where the
truck stops are, where to get a good meal, and learning interesting
facts about the area I'm driving in.
 
I miss the good old days of CB. But not it's later days that partially
caused it's demise due to abuse. Then too, the internet has been on a
similar downward spiral. The early internet was both fun and useful.
These days its been taken over by that repulsive Facebook and if you
want anything useful, such as a repair manual, be prepared to give away
your identity to some crooks, and pull out your credit card. Or just
waste hours sorting thru all the bogus claims that say "FREE" manual or
whatever.
