KX3 DX

Just worked TX5T on 14.028 with 5 watts on the KX3. I don't usually
brag, but this was a nice QRP contact.

Re: KX3 DX

Scott,

I don't usually brag either, but this is not about me, rather my KX3.

On Saturday morning last, on 14.221, I worked a pileup while activating Porthcawl Lighthouse for the first time during International Lighthouse and Lightship Weekend. I was scribbling down QSOs at a rate of one a minute at one point. The sea water take off clearly helped.

KX3, 10W, SSB, Buddipole horizontal 20m dipole at 5m height. Outstanding performance from this kit (and in the rain too!)

Admittedly, the Rx plays a part, but the ham on the other end of your signal
can't tell the difference between a KX3 and a 6AQ5.

As the saying goes, "Five watts is five watts".

I think what you're actually saying is that you're amazed at what can be
accomplished at QRP power levels.

Remember, if you are being received at 20 dB over S9 while running a
kilowatt, you'll still be S5 at 100 milliwatts.

Re: KX3 DX

What you just posted is a combination of fact, fiction, and oversimplification.
I can absolutely discern the difference between signals received from better and lesser transceivers if the disparity in transmitted signal quality is sufficiently large.
Conversely, I am routinely complimented of the "clean" quality of the signals I send and the fidelity maintained in them from folks that have no idea what my equipment is.
Not ALL 5 watt transmissions are created equally.... that can be demonstrated both qualitatively as well as quantitatively.
Some transceivers are superior to others. Tyat is a simple fact. Even with two identical transceivers, one then must consider proper calibration, setup, and ancilliary equipment.... power supply, microphone (huge potential diff especially in concert with pre-processing of signal put into transceiver front end), grounding, and then of course.... the ANTENNA SYSTEM composed of everything from the antenna connector to the tip(s) of the radiator(s) and return paths.
5 watts into a dummy load is most definitely not the same as 5 watts into a practically perfect radiating system....
Even into 2 practically perfect radiating systems, ground, elevation, et al. come into play....
Enough of that... point made...
To the OP....Great QRP contact, N9AA.... keep it up, Scott!

OK I'll give you that. A 592 signal WILL in fact, sound different from a 599 signal.

The saying is an oversimplification. The KX3 includes two important
tools to increase talk power on SSB -- TX equalization, which can be set
to emphasize speech intelligibility and minimize power wasted below 400
Hz, and amplitude compression and peak limiting, which brings quieter
speech sounds closer to the level of louder ones. When set for about 10
dB of compression on voice peaks, it makes 5 w the equivalent of 50W,
and the TXEQ settings add 3 dB, making 5W the equivalent of 100W.

These tools, which are called "audio signal processing," have been used
in broadcasting since at least the '50s. They are also built into the
K3, K3S, and KX2.

Re: KX3 DX

So if I utilize these same compression and hpf adjustments and
equalization my 100W will sound like 1KW?? maybe on paper..

Re: KX3 DX

In reply to this post by Curt Nixon

That was unnecessary.... It was neither asserted or even remotely
suggested that 5 W or 100W could be made to "sound like 1 KW"...

IN FACT, power level has little to do with HOW something sounds...
volume? yes, quality? Not nearly as much.

The POINT that I and Jim (more succinctly) were trying to make it that
not ALL 5 W signals are equal.... not by any stretch of the imagination
of by any level of desire.

All things being equal... a PROPERLY formed 5W signal will be "heard"
(more accurately "understood") by a larger "audience" than a POORLY
formed 5 W signal....
And a properly formed signal will likely be understood by more folks
than a poorly formed signal pushed out at higher power.

PS -

Not sure why, but there seems to be a lot of cranky folks spoiling for
an argument/fight lately...

Chill out, guys!

73,

Re: KX3 DX

Well..he DID use the term "equivalent".....

I get it, but you know what it will sound like if everyone starts
crankin on that compression knob :)

I agree with everything else you just said BTW

Re: KX3 DX

In reply to this post by Scott Manthe-2

Strange, cranking up the compression doesn't seem to be affecting my 5 watt CW signal much :-)
In keeping with the discussion, I use a small amount of compression and no TX equalization on SSB and have had good success and audio compliments at 10 watts.
