I just uploaded the new firmware version which went smoothly.
After that I had to do some filter settings as I had my FM filter (yes, it

Normal procedure: go to Config, select a filter and

I agree that auto-spot doesn't seem as reliable as in earlier
versions. When I inject a continuous tone, it works fine, always
coming within a few Hz. For actual cw signals it now seems to be more
easily fooled, often tuning low - noticeably different to me, one who
uses the feature constantly.
After posting about my problem with not getting the dialled up power output
in DATA A mode, it occurred to me that perhaps it might be a good idea to

On Sun,
We've just completed the most extensive K3 firmware update ever. The
full list of changes is provided below.

(K3 Utility rev 1.1.4.1) or else you won't be able to load all
components of the upgrade. It's available on our K3
Wow, totally outstanding, Wayne. Congratulations on this major milestone!
Can't wait to see how it works. Looks like my K3 will have this revision
loaded in it when shipped, then.

The SSB transmit chain has had a major rework. The
results are very impressive.
1. The ALC is vastly improved. In fact you could say
that the K3's ALC is perfect because it does not
contribute any measurable levels of IMD to the SSB
signal.
2. The increase in IMD levels when you turn on the
