I bought a K2 SN 670 to complete my collection Elecraft.
I now have K1, K2 and K3 + P3.
The K2 serial number is very low and I think some changes are essential
and others less so. Can anyone tell me what mods are the really important?
I also have a problem that occurs very frequently: when I

I just noticed that when the Manual NTCH is engaged and the frequency of
the notch is set using VFO B - the main VFO is locked. You cannot change
frequency with VFO A, however the frequency can be controlled via HRD.
This lock can be toggled off by pressing the A/B button.
Is this a feature?

Go to the Elecraft website and download the K2 A to B instructions. That

You may want to also download the instructions for those mods as well.

Not much has changed in the KX1. About the only changes have been a

Congratulations on your K2. Once you have it

Yes, but that does not answer my question. I could have been more clear I
guess. I am thinking that this 3.5 to 7 watt range is to achieve 100 watts

to be lower.

There are two sources of frequency drift: the TCXO of the K3 and the
LO of the transverter.
The combined error determines the final frequency stability.
Upgrading to the TCXO-3 improves K3 frequency stability by
ten. Adding the EXREF board improves this.
To improve the transverter LO, it

I have heard a few stories about the difficulty of installing the KRX3
sub-receiver into a K3. Is there a consensus as to whether this is difficult,
moderate, or reasonably easy straight-forward to install.

Not difficult,just involved. A second DSP board needs to be mounted

If you can afford it, go for a second K3. No need for the sub-rx and some
of the other options. A pair of K3s is arguably the ultimate SO2R
configuration. At least for my pea brain, two identical radios is much
easier to handle than different ones, even ones as conceptually similar as
K3 and KX3.
