Dear Fellow Elecraftists,
I have been adjusting/measuring many HF rigs the last 10-15yrs or so,
using a calibrated Marconi generator.
From what I've found on S-meter accuracy, I conclude there is no such
thing as the 6 dB per S-unit. Offical tests in magazines and books
verify this too.

I can't argue with your preferences. The K1 is a fine rig, I'm sure. I have a
Wilderness Sierra (Wayne Burdick's predecessor to the K1), and I enjoy making
QSO's with it. However, when I hear a KW contest station on 80 meters working

This has certainly been an interesting discussion. Usually this question comes
up in asymmetrical situations-- where the op at one end is running QRP power
levels and/or using a marginal antenna, and the person on the other end is
running power that may be orders of magnitude higher than QRP
I don't pat myself on the back or feel that I have achieved something if I
manage to make a DX contact. I'm just plain thrilled.
Anyone can run the full legal limit to a tower mounted beam if they have
deep enough pockets and think it's important enough to spend that kind of
money. But do they
All these numbers are fun but do not mean much. What you do if you
run QRP is learn about propagation. If you have the prop, you work about
as well as a 100 watt station. If you don't, go do something else.
Yes if you run 1500 watts to a good antenna you will get the DX
first. At 5
Who does the work in QRP?
It always is the guy with the better antenna's :)
Amen to that.
I'm working on QRP-WAS, and I have to admit that most of my QSOs are
with hams that have some huge hunks of metal flying above their shacks.
Those are a lot easier for everyone involved! But I've also

Sometimes I use my 400mW Mizuho or HB rigs, sometimes I use the Omni 6 and
the Centurion at 1kW out.
The type of tool depends on the type of task. One's not any more fun than
the other as the saying goes, it's all good!

Great thread!
Before I make my point I would like to point out that I work almost always
qrp using my KX1.
One of my Christmas presents this year was a NOSS CW Tuning Indicator (SMD).
I built and installed it today and it works fine!
FWIW. I occasionaly tune into a 17 meter

boy...am I asking for trouble with THAT line! LOL.

In a ragchew or traffic handling, that may be true when the QRP signal is weak.
But this is NOT the case in DX'ing, as in, get your call across to work a
Unh?
How does one know your sig is QRP? Unless you send QRP with your
call (I never do).
Receiving QRP as weak sig is a MYTH!
I have heard QRO stations in the noise as well as QRP stations.
When propagation is there, does not matter what power you use, QRP
sigs is just as loud as QRO sigs,
I'm always amazed when contesting (especially on phone, er, I know,
what is that?) and part of the report indicates power level, such as Q
for QRP in the ARRL November Sweepstakes. More often than not if I get
a comment from the other station he/she usually says something like
Wow, great
The NCDF beacons are the best way to figure the difference, as the call and
the first dash are sent at 100 watts, second at 10, third at 1 and the last
at 100 mW. Yes, there are times when the AGC equalizes two, three, or even
the all dashes and you hear no difference between 100 W and 0.1 W. But
I believe that the work being done in a QRP QSO is done by the RX station, not
the TX station. That is, if there is any work to be done.
Sometimes propogation is such that QRP signals are Q5 and work just as well
as QRO. In that case, nobody is doing anything special.
The time the QRP op
I agree with Ron, 1000%
Unless you sign /QRP, how is a station to know you are QRP?
There are so many variables . propagation, antennas, location,
height above sea level, etc.. Let's say the station doing the listening
is in California. Your 5 Watts in Georgia may be a whole ton louder
All the rationalizations and anecdotal experiences aside, there is no escape
from the physical reality that a 100 watt station will be 13 dB stronger than
the same station running QRP 5 watts. Whether or not this 13 Db is crucial
depends upon propagation conditions and noise and QRM levels at
Well, lets deal with facts on your hypothetical QRO station:
Transmit power 500 watts S-9 +10 db
50 watts S-9 (+ 10 db over 9)
12.5watts S-8
3.1 watts S-7
You lose 1 S-Unit each time you're reducing power by 1/4.
One S-unit consists of 6db increase
