There is a standard in Region 1, but, to be honest, a standard which up
to now has almost totally been ignored by the industry.

I think this gets back to my comment about resolution. If you are
using a quantized bar-graph display it is easier to change the
calibration than to change the resolution. OTOH, three digits would be
nice or even an analog meter. (I actually still prefer analog meters
for a lot of things,
I just added a task to my future-K3-firmware list: allow the VFO B
display to optionally show signal level in dBm. Three digits. Just for
you, Brian :)
One can not help but love these guys.

On this reflector, I'm surprised no one has mentioned the XG1 and XG2 kits that
can be used to easily calibrate an S-meter *to* a known standard. I used the

enough!), and then to check the meter on my

Hallo Bill,
user-programmable. We now have the opportunity, given this new feature,
to experiment and see what really works best, and make a LOGICAL case
for establishing that as a standard.
6dB makes a lot of sense to me: 1 S-unit = 6db = factor 2 in voltage.
This is the Region 1
Very good.
I'm sure that, in order to facilitate better understanding, all contesters
are careful to give accurate S-meter reports in every exchange too.;-)

Hmm, peak rather than RMS voltage? If you are averaging then it needs
to be something
I do wonder what timing Wayne will use.
And don't forget attack/decay time for the peak-reading meter and
integration time for the RMS meter function. :-)
You could of course read a stream of values into a computer via the

I'm amazed by this thread. Most S meters are pretty much AGC
voltmeters. They register practically nothing until the signal is more
or less readability 9 and then whizz up to S9 or so after which they
may approximate to the +10, +20db calibration. Whatever the K3 has
