Howdy all,
I want to move a base station of a mobile radio system to a remote
location where I hope to get better coverage, but I want to keep the
mic and channel control in the present location.  I have access to

Recently, at a Radio Shack store at the telephone accessories section,
I noticed that telephone extension cords were available in lengths up
to 25 feet (but I didn't notice any that were longer).
Is that because 25 feet is the longest you can go before there's a

Can anybody suggest a news group for comments on items of domestic
electrical equipment?.
I am looking at buying a dvd recorder from ADSA and wondered if
anybody could comment on it

I'm about to buy a genie or wizard ESR meter and I was wondering if they can
be used to test SMD capacitors?
Any other tips for testing SMD capacitors of unknown value would be greatly
appreciated.

I've heard good things about the $35 CSI generic soldering stations that
look (and apparently work) like Hakko 936 units.  Commonly available from
http://www.circuitspecialists.com/ and http://www.mpja.com.
I've been looking for a good, cheap desoldering unit. The Hakko 808 is ...

I have a couple of laser power supplies that I'm looking for info on.
Is this the place to ask for such?

I'm being buried in wall warts and power strips.  I won't bother everyone
with the usual gripes about them but will ask some questions as to whether
my solution is feasible.
I've noticed that all mine are either 3, 4.5, 6 or (in one case) 9 volts

Anybody out there with a home brew calibrator for this
unit? Thanks, Don, donaldcontant_6@sympatico.ca

Would anyone know where I could find the schematics for a Directed 2400d
mono audio amp. 2400w @2ohms
This a car amp.

I got an old 1650B without system disk. Would somebody make a copy with
another 1650B? I will pay $10. Let me know. Thanks! I need it to debug
my board and can't afford a new one.

When I feed a 1V sine wave into both ch1 and ch2 of my Tek 2465A, and set it
to display the difference (invert ch2 and add the channels), I do not see
the expected flat line.  Rather, there are some bumps.
So, I presume this means that one or both input amps are not quite linear.

I have the following list of test equipment FS. All the equipment is
tried & true in super good cond. inside and out w/ shipping included in
the price (to the U.S lower 48). Please email any questions or requests
for info to: Homebrueletronics@yahoo.com

Can anybody help me find operator and service manuals for the
Tektronix AM502 differential plug in amplfier?
Thanks,

Hi,
I'm looking for a manual/schematic/parts list etc for the HP465A
amplifier.

my friend is trying to mend my external drive/enclosure. I said I'd try
to find a schematic for the pinout on the ribbon cable. The cable seems
to be different than the standard one. There seems to be a lot more and
finer wires, though the connector is standard. Please can anyone ...
