I will be upgrading my K3s but it seems that people often do not pay the

Hi Bob,
The new frequency coverage is still part of the 160-meter band. If you need
quick access to the 600-meter range (~475 kHz), you can use any of several
different ways to get to it:
- the four per-band quick memories on 160 m
- the 100 general-purpose memories
- direct frequency entry
That is also my big reason for ordering, I like to play around down
there as an SWL. I'm 95%+ CW [really crummy hearing for SSB], I really
like the current QSK, and I'm looking forward to seeing if I can tell
any difference. I'm sure I could have if I was younger. :-)

Gareth,
That is NOT correct.
You must do things in order and all will work out properly.
First, the 100 Hz WWV subcarrier should be outside the passband of the
SSB filters, so it will have a very low amplitude.
It is better to use the alternating 500 and 600 Hz as well as the 'on
the minute'
Some users of the new synthesizer have also reported an improvement in the way
diversity mode sounds. This is due to a change in the way the receivers are
driven by the synths.
In diversity mode, as long as the main and sub crystal filter offsets are
matched, both receivers are driven by the
To me I thought it was worth it to get the extra range under 500 KC since I've
had an interest there since I was a kid.
I would say if it gives you something you want then it's worth it.
As far as actually hearing a difference, well that takes someone with a bit
better ears than me.
This has really gotten so far beyond anything rational.
Should I upgrade? Shouldn’t I upgrade? Will it matter to me since I only
operate on empty bands? What is Elecraft’s business model? What is the gross
margin on the new boards? What is air?
Good grief guys. Upgrade. Don’t upgrade.

You need to research the concept of the time value of money. As I
said before, if the benefit is useful to you now, by all means buy the
upgrade now. If it isn't, it simply becomes a race between inflation
and potential increases in cost whether or not it makes any sense to do
so.

The KX3 (or the K3 or K2) will not control its power output properly

The ALC meter on the K3 and KX3 is a combination of an audio level

Once I'd gone through my modified version of Wayne's process for adjusting
the VCO (i.e. adjusting the VFO to have the WWV 100Hz sub-carrier on
100Hz), I realised that this applied only to LSB FIL1.

Hi Bud,
I believe it's still beta. I'm running 1.35 on my P3 and 1.22 on my SVGA.
The freezes have been far fewer but it's still not 100%. However, the fact
that it is beta should not prevent you from using it. Beyond the occasional
freezes I have not seen any other problems with the firmware.
If you use SSB, and power consumption is a concern, you’re better off running
at 3W, since a more efficient output transformer winding is selected, reducing
transmit current consumption. For CW, you can run up to 5W in this
power-saving mode. You can tell if the hi-Z winding is selected
Unfortunately the shift in dial calibration between filter settings is due to
the limited resolution of the DAC converters that control the BFO. It is a
design compromise, not much you can do about it.

you need to run
