The ftdi devices have free and open licence-free drivers for all platforms.

In case anyone besides me wondered why the -33 dBm level was added, there's an advanced RF gain calibration in the K3 Utility which uses -33 dBm (in addition to -73 dBm) for even better linearity of the RF Gain (RX) control. More details should follow when Dick K6KR returns from Visalia and updates the K3 Utility.

Only as a "serial converter" using FTDI's own UID/PID. When one
needs to support a specific device, e.g., "Elecraft XG3," it is
necessary to license and certify the drivers at substantial cost
before some operating systems will install them. In any case, the
CPU side of the equation is only part of the issue ... and still
does not account for the additional cost/complexity/size on the
device side.

Yeah, just to prove those Italians on 40m really ARE 40 over 9...
Stacked 5 element yagis and push-pull 3CX5000A's.

Will be interesting to see if the phase noise is low enough to allow
us to run filter shapes down past -60 dB.

Zero dB will allow me to use a tuned rubber duckie per band for
precise pattern measurements and RX antenna sensitivity and null
adjustments. Turn it on, haul it way up in a tree, and go make
adjustments. Hope any auto turn off is an option. Also maybe a very
slow beep for power saving. Maybe even <long bleep> .... <long bleep>
K2AV/B 0. And then K2AV/B BATT when batt is low enough to drop
out of calibration. Maybe even cycle 0, -33, -73...

Isn't it awful how much new stuff we can dream up on top of a new
release. :>) But I ordered mine, so I've paid the dues.

Re: XG3 All-Band RF Signal Source/phase noise performance?

In reply to this post by wayne burdick

Someone asked about using the XG3 to measure the skirt attenuation of a
crystal filter.

If the phase noise is -105 dBc / Hz, then with a 500 Hz crystal filter
the filter skirts will disappear into the noise at about -105 + 10 *
log(500) = -78 dB. With a 2.7 kHz filter, it works out to -71 dB.

Re: New Elecraft product: XG3 All-Band RF Signal Source

In reply to this post by Doug Person-3

Cycles are oscillation measurements.

Mr Herz was a man who passed away many years ago.

I prefer the use of cycles, because they indicate the exact type of the
measurement, but I'm just an old geezer who prefers many aspects of the old
days.

Glad to hear that my selling of the old HP Analog Signal generator was a good
idea.

Not many people at all would understand the measure of inverse seconds.
Hz or cps are measured in 1/s increments.

You are an old English-speaking geezer (or at least an American-speaking
geezer.) But the modern metric system (SI, the International System of
Units) tries to name derived units after people so as to avoid the
problem of "cycle per second" not translating well into other
languages. (In not all languages does the word for "cycle" start with
the letter "c". After all, it was the French, not the English, who
first introduced the metric system.

That's why this English-speaking (and French- and German-reading) geezer
likes to follow the metric system style guide, found at
<http://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf>.

According to the USPS tracking my XG3 will arrive today.

After we celebrate my Grandson's return from his second tour in Afghanistan
tonight, I will be calibrating the my two K3's S-Meters and the P3 signal
levels.

An all around fun night at N5GE!
