Hi Audioguru
Hehe, not that old, theres a digital family called RTL, hehehe -
Hi both of you
How was it with the old RTL digital ICs, didn't they source more than sink?
Or was it an another family, that have PNPs output, only similar to RTL?

Hi
i m using yagi tv antenna
A TV antenna is not tuned to the FM band, and is not very good for DX-ing
at FM! Was the other two amplifiers not good enough for amplifying the signal?Hey SM2GXN, yours pdf file is not opening in my computer
It opened nice here, its an article from an australian mag, with an antenna amp.
Do you have Acrobat Reader installed?

Hi shaiqbashir
Do you have this book:
Engineering Electromagnetics, sixth edition, by William H.Hayt, Jr. & John A.Buck ?
If you have, please upload it!

Hi
password? yes, i do. the computer remembers it
You have to click out "remember password" and remember it by yourself!I have my speaker fixed! thanks a lot!
Did the powercord have plugs in each end?another question.. when my speaker got busted.....
Connect the respective RCA jacks to the soundcard output, there are cords
that will fit directly. The mic output on monitor connects to the mic input on
the soundcard. The headphone output you connect to a headphone, if you have one, the speakers then usally go out.

Hi MrHeckles
Try this first! As you see, i have added a resistor, that will draw the switcing
action inputs to ground, when the SW1 is open.

Hi MrHeckles
How much current? Voltage?
A little schematic would be nice!

Hi saso
What do you mean, helping you with the topic "hm" ? ??? ??? ???
//Staigen -
Ok, but dont you have some kind of password?
Did you replace your cord?
Do it have plugs in both ends?
//Staigen -
Ok, but powercords of this type usally have a plug at the other end too!

Hi Ante
Oh, was it that you meant, did he have to put the speaker apart to find that
error. Of course you look for outside damage first.
To Logan:
I dont see you at MSN anymoore, where are you?
//Staigen -
Good luck!

Hi Logan
arrow in the diagram
What diagram, did you forgot to attach that?it doesn't perfectly fit my adaptor (its terminals are flat), its loose
Wich adaptor?lets say,the two terminals of the plug touched each other, what would happen?
The power cord?
If the short was in the power cord i dont think the transformer inside the speaker is damaged! Check the power cord, and replace if open or bad! Check for voltage at the transformer, but be careful!
Hey, i just got your picture, replace the power cord!

Hi babykoh08
What is it you want to do? A PSU without any IC:s, using only transistors?
Or one of the 0 to30 Volts PSU:s described here on E-Lab?

Hi
I where just going to propose Intersil ICL 7216(i belive it is the name for it) IC
I am not sure about the name, i have the book in a place where i need daylight
to get it, i have a look at it tomorrow.

Hi
Propotional means that you could move slowly with the car by just press the
controls a little bit. If its only zero or full speed backwards and forward it is
probably not propotional, and will work just fine here. Use some 1N4001,
they are cheap and redily available. And, yes, you should use a diode
backwards over the relays.
PIV means Peak Inverse Voltage and is the max voltage the diode can stand
in reverse.
BTW, how is it going with your PSU?
//Staigen -
Hi
Was it a propotional control of the motors?
And was it digital?

Hi
Can you describe your antenna and topography?
Isn't the other two good enough?
Here are the links:
http://www.electronics-lab.com/projects/rf/003/index.html
http://www.electronics-lab.com/projects/rf/022/index.html
And you got one from SM2GXN
Hey SM2GXN, what do you think of using miller integrators as VHF amplifiers?
You, if anybody should know about this!
//Staigen -
Hi again Serge
Than i belive you have to supply us with lot more information about the IC!
Is it a Texas Instrument brand? ALL TI IC:s beginning with SN72... is linear
OP-AMP:s! And i have never seen a 28 pins OP-AMP in my whole life!
Is it linear or digital?
Also, its for his vifes translator. Translate what? From what? To what? How
old is this translator?
Is it possible for him to come online and discuss this directly in this forum?
It seems that hte more answers we get, the more questions arise.
Maybee someone else know more about this IC
//Staigen -
Hi Logan
I dont blame you, and i have to check this out! Here in sweden it is called
"Dator" and the translation is computer. And i have seen the "large box"
called computer elsewhere too. But i have never, until now, seen it called
CPU, because the CPU is the IC inside.
So folks, which is what? Maybee we all are right?

Hi Ante
The spark can have been virtual! She maybee belived she saw a spark.
//Staigen -
Hi Ante
With the speakers closed? ;D ;D ;D
//Staigen -
Hi Logan
the rectangular box with all the drives, slots, boards, cards, etc
That is the computer! If the lecturers tell you that it is the CPU, you can tell
them that they are wrong! Then you also have the periferal furniture too, the
monitor, the keyboard, the speakers, the mouse, the modem, the webcam and
so on.

Hey Logan
When doing this test, with the screwdriver, also hold your finger at the
metal part of the screwdriver, and dont hold in anything else, than your
body act as an antenna, and you hear a highpitched hum from the
speakers, if they are allright.

Hi
I suppose so, dont it do that for you? If so, the IC is surely damaged!
