Best Reference Book for Win 7 and Win 8.1?

[Jim Brown-10]

I've recently replaced one of my computers with a Win7-64 Pro machine,
and my XYL's with a Win 8.1 box. There are certain "wierdnesses" with
both of these OSs that I'm finding baffling, so I've decided that I must
RTFM.

I used to do this by grabbing a bunch of such books from the rack at
Borders or Barnes and Noble, and a cup of coffee, and buy the one (or
two) whose writing style communicated well with me. Here in Santa Cruz,
that option is no longer available. Suggestions?

73, Jim K9YC

Here's a start: some articles on Windoze 7 and 8.  A few of them have
links  to reference material you might want to download.

Microsoft has some on-line info and tutorials at windows.microsoft.com which
might be of help (try the "how-to" section.) If you need more in-depth info
MS Technet is a resource we "tecchies" sometimes go to. (Scroll down to
the "Info for" section and click on "IT professionals" to get to Technet. A
search of the Technet forums will sometimes yield good info.)

Otherwise, you could use the technique I've developed over a number of years
spent fighting with computers running Microsoft products:

1) Bang head against a concrete wall until head is bloody and throbbing with
pain.
2) Repeat as needed.

Hope this helps. 73, Al

re: Al Gulseth

Thanks Al for the reference to on line help. Al good.
BUT you are heading in the wrong direction with advice to,
'Bang head against a concrete wall'.

Instead please direct energy towards the computer.
After 56 years in electronics my advice has always been-
"One kick is maintenance, two kicks is abuse".

I wonder if anyone can offer some advice please?

I've just put together a KPA-500 linear amplifier kit and everything
seemed to work fine until I switched from standby to operate when I get
a 270v ERR message, which needs a hard reset.

The 60v line is present (68.5v) and the interlock works as it should do.

I've checked and there is no 270v line present for the PA T/R switch
reverse biasing - grey wire on PSU.

That is until the grey wire carrying the 270v line from the PSU, which
connects to P2 on the PA board is unplugged and then I can see the
required +270v. Clearly the PSU is working.

As soon as I reconnect the grey wire to P2, the volts disappear and R17
on the PSU board starts to get hot.

I've found a circuit diagram for the KPA-500 on the WB4KDI web site:

http://www.qsl.net/wb4kdi/Elecraft/index.html

Here it shows R17 in the 270v bias circuitry as a 10K rated at 1W.
However, R17 in my PSU is actually a marked 1K rated at 1W (measures 998
ohms) Is this the problem? Wrong resistor fitted in the factory?

I dunno whether this actually is the problem or whether Elecraft have
changed the circuitry since that earlier circuit diagram referenced
above was made available and the fault is elsewhere.

Sadly, there was no circuit diagram in the handbook provided with the
KPA-500.

Any thoughts please?

Thanks in advance!

Hi Keith,

Thanks for your comments and also to several others who replied
privately. I have now resolved the fault that was causing the +270v T/R
bias line to be shorted and the "270v ERR" hard fault to show.

As several others have discovered with the same fault, the problem was
C2, a faulty 0.01uF, 500v, 1206 SMD capacitor; part of the T/R circuitry
on the PA board, which was going short circuit when the 270v was
applied. The capacitor tested OK without volts applied, but on
inspection with a magnifier had a hairline crack at one end and fell
apart when I removed it.

C2 is easy to get at once the PA assembly is removed for inspection and
repair, but of course much of the KPA-500 has to be disassembled to do so.

Anyway, I have now replaced the faulty capacitor with a good one and all
is working correctly. I assume that R17 has been reduced in value from
10K to 1K on later versions of the KPA-500 and that value is correct.

Apparently, from comments received from several other folks, this is not
an unusual fault and Elecraft are well aware of the problem.

Luckily, I was able to fix the fault here in my workshop. Others have
not been so lucky and have had to return the PA assembly to Elecraft for
repair.

Now to test the newly built KPA-500 with my K3 and do the final
adjustments. I'm keeping fingers crossed there are no more nasty surprises.

Thanks everyone for their comments and help with this particular KPA-500
fault.

Best wishes
