Every time I try to buy something there, even if I pay cash,
they try to get my address and phone number. I always have
to argue with them. "You don't need my phone number to send
your stupid catalog, and I don't want the catalog anyway."

But they still argue they need it. Eventually I win or
I walk out with my money and no product.


I've seen this exact post before. It was posted long time ago and
apparently the OP likes to repeat it, or maybe Wes Groleau decided to
reply to a really old post. It's old news. Obviously if it is store
policy where they refuse to sell without an SS number, give them a fake
one (and make it obviously a fake, like 123-456-0000) or just don't buy
from them. I've been at the grocery checkout and they wouldn't ring up
an item at the price they listed on their own shelf, I don't argue, and
I'll leave the whole mess on their counter so they have the fun of
putting it all back and I walk away. There are other stores. Let them
win the argument by losing the sale. Then go call the State Attorney's
Office to find out how to file a complaint and determine what other
action you can pursue against them.

By the way, I've never had Radio Shack ask for an SS number in the 30+
years that I've purchased from them. They have asked for a telephone
number which I refuse to divulge. They persist but I refuse and simply
put it, "Do you want the sale or not?". If I'm paying cash, they don't
ever get get any personal info. They might claim they need it for
warranty purposes but the law doesn't require you to register to
exercise the warranty (you only need to prove at claim time that you
were the purchaser).

Hi

Have an HP8444A tracking gen with blown Si-NPN oscillator transistor (4

hopefully. Any suggestions..

Thanks

Hi Colin,

In my list is no JEDEC type, but i have the data of the transistor

1854-0292:

FT min 1.6GHz @ IC 10mA
HFE min 25 max 150 @ IC 2mA
VCE min 15V
PD max 200mw
IC max 25mA
C CB 1,5pF
NF max 3.5dB

I found the 2N2857 is near in most
data, maybe a selected one?

I hope that helps a bit,

If you stretch a string on a globe from London to Florida, it will show
the 'great circle' route that's the shortest, and that should be your

In fact the Avalon Peninsuala in the most eastern part of the island portion

of the province of Newfoundland and Labrador, Canada, is a 'Way Point' for
many transatlantic flights headed to/from Europe.
Clear days Transatlantic flight con-trails, at 30,000 feet etc. can be seen
almost continuously.
That is why so many of the flights that were prevented from entering US air

Many US/Canada friendships were founded between grounded travellers that day
and eastern and western Canadians who voluntarily accommodated them during
the delay.
Cape Spear near St John's is the most easterly point in North America.
Marconi received the first transatlantic wireless telegraph signal near St

PS. Staff at the National Historic Park at Signal Hill, St. John's, which
incorporates the memorial and events which celebrate Marconi's first

"No, but sometimes you can see "Whales"! Smile

Greetings..

THIS question is a bit tough to answer. Why? Due to the fact that it
depends on how often you *really* use it (power up, power down), treat
it & to some extent how clean the power is to it if used on an external
supply. Temperature, humidity, salt, dust and even altitude comes into
play in its environment for "long-term durability" calculations. Of
course, the best source of relibility/durability figures will come from
one source - Fluke. Talking to a sales representative should answer
these questions if its use is THAT critical.

Good luck.

Not sure if you were interested in trying www.labx.com

LabX an online auction and classified website for lab and test
equipment. It's a marketplace, so you can sell it to end users
directly or dealers and will likely get a fair market price.

Anyways, it's a thought if you still have any pieces available.

Best Regards.

This isn't really a for sale posting.. (that's already out there). My
question is has anyone had experience selling used electronics
equipment to these used equipment dealers?.. I'm picking up a pickup
truck load of stuff tomorrow and I'm trying to see the best way to get
rid of some of it.

Including what I'm getting tomorrow, I've got

Sorenson DSC150-7 150v 7a adjustable DC power supplies
Valhalla Scientific 2301 and 2100 watt meters
Tektronix OF150, OF235 OTDRs
Tektronix 2215 & 2215A o'scope, and Phillips 3217 o'scope
some other fiber test equipment.

For example, I've got an e-mail into American Test Equipment in Va..
they show for sale an OF150 for $4295, and an OF235 for $7750. I don't
expect that much for the equipment, but what should I expect?.. 50%,
25%, 10%?..

Anyone comment on tech-systems electronics?.. They are showing $995
for the OF150, around $400 for the scopes..

Just wondering how I'm going to get rid of some of this stuff..
certainly I'd rather have it go to an individual rather than a reseller
if the price was the same.. if anyone is interested in buying or
trading the e-mail addy is correct.

Thanks,

Jim

If you have no experience in installing one,then you can possibly damage
your scope to where it's not worth anything anymore.

You are also going to need the proper ribbon cable set for the DM44 option.
And the DM44 service manual!!

I would not advise it.Buy or trade for a complete 465BDM44.

products.)

When I bought my 465B a number of years ago, I started thinking the
same thing. Fortunately, I had the complete service manual and I was
able to see how much work it would be to install, and I could also see
that it would make the scope much harder to get into if it ever needed
service.

Finally, I realized that most if its functions could be done better
with the newer instruments I already have. Do I gave up on this quest
and have never regretted it.

If you really want the DM44, you'd be much better off buying a
complete 465B/DM44 and selling your 465B.

BTW, the 465B is still a great scope. ;-)

I am not shure if the OP is just willing to replace the DM44 on his
465B . Or if he is going to install one on his 465B that is right now
without the dmm.

In the latter case, this would also mean some metal cut ourt in the
housing of the 465B scope. Hard to do withourt proper tools.

I'd go with Jim recommendation: Buy a complete 465B/DM44.

just my 2cts. ;-)

Hello all,

I am sorry for taking so long to get back to you all. It has just
been a rather busy week.

However I wanted to thank you all for the input. And, following the
consensus, I will, hold off buying a DM44 for my 465B as I do not
have the skill to install one, as well as that it simply ounds like a
bad idea trying to add a DM to the Tek.

Thanks everyone. I appreciate the help.

Respectfully,

Sam

Good morning,
a friend of mine have inserted this post on a Forum I created on my site
www.etantonio.it/en , this is the question :

"Someone knows something about LTA/WTA circuits?
I mean the best approach to the problem,
the best topology and all that can be usefull
to design an accurate and high-speed LTA?"

I don't know the answer, if you know it please post it just following this link:

Many Thanks,

Eng. Antonio D'Ottavio

Start with an N-input AND or equivalent.
Each input is driven from the output of a 3-state logic circuit; state
1 = NOT VOTED, state 2 = YES, state 3 = NO; reset all to state 1 at
power up.
The 3-state logic is wired to prevent a voter from changing the vote
after voting; both state 2 and state 3 lock out any inputs.
I designed and built such a beast about 50 years ago using relays;
rather simple.

Alter above suggestion as requirements dictate.

My solution has been to remove the display (carefully) and clean up the
"zebra" strips both top and bottom and clean the display and PCB. Then
replace (try not to put your fingers on the strips)
It has worked for me on a few meters I have played with

immune (or less-apt) from display fade?

I'm asking this because Fluke multimeters cost $300-$400 for the new
models replacing the 80 series.

What I want is the Fluke's alert beeps when a new min/max is sensed.
Are there any other brands of multimeters that have this feature?

Why do Fluke multimeter LCD displays fade? Any Fluke model immune?
