Don't confuse Chrome OS with the Chrome browser. They're very different
things.
The latest Pixelbooks should be able to run Android apps natively, but if
you need to, you can use one of the tools like Crouton to enable running
Linux. I do that with my older Chromebook.

Anyone know if Elecraft utilities can be made to run on a Chrome OS? The

No. There is no power source in the ACC connector from the K3. Your use of the
12V connector is the right solution.

The resolution of the frequency being reported from the K3 to the KAT500 is 8
KHz. This probably does a better job explaining why the relays switch every 8
KHz than bin size. I would bet that once in a while you will find two adjacent
frequency segments that fall in the same bin, and no

There are instructions for doing so in the operating manual. It's kind

What happened to using a Simpson 260 or 270 or Triplet 603? Those are
actually better for finding a peak or null, which in both cases are only

find the life of a DVM to be zap.

They may be meaningless or they could be very useful. Finding a peak or null,

With my KPA500 and SSB rag chews I keep the fan on NORMAL. It does

There is a big difference between accuracy and precision.
Precision can be accomplished by adding the extra digits, but the
accuracy of the instrument will tell you how many of those extra digits
are to be considered.
Most digital voltmeters, even the cheap or free ones from Harbor
I do the same thing for the same reason when operating FT8 (40 watts out)
but at fan speed 1 - the temp then never goes even close to where it would

for lower noise and probably the same effect.

Yep, ur right Don. A freebie Harbor Freight digital voltmeter appears to
have a helluva lot better accuracy than reality.
Digital calculators on the other hand, ARE accurate.
This changes our mind-set, simply because we see all those digits past the

John,
It is good to hear that you have had success with a fan setting of 2.
Like most mechanical components, there is a wearout time, but I suspect
it is in the vicinity of 1000 to 5000 hours. That is a lot of operating
time.
If you are concerned about wearout, just turn the KPA off (or

Is there any harm in setting the fan at level 2 and just leaving it
there? I would think the fan might wear out a little faster, but how
much faster? The reason I ask is that when the fan control is set to

Petr and all,
Those digital instruments that show 2, 3, or 4 decimal places have given
us a false sense of accuracy.
For instance an instrument that is accurate to 5% and has a 4 digit
display can show us (when measuring a 5 volt source) anywhere between
4.750 volts and 5.250 volts and still
Hi Wes,
excellent!
Many thanks for this post which is nicely explaining what is going on about

In fact until now no one talked about the calibrations, uncertainties,
errors, accuracy, reading errors, uncertainties A, B and combined
uncertainties etc. In that case there
