On behalf of a friend (in Australia) who is thinking of a K2, can anyone
give an approximate idea of the time needed to build a K2 kit
Better still has anyone got a K2 to sell (In Australia)

Is your data mode set to DATA A? If so, there should be no difference
between LSB and USB. Tell us more about your setup and what you are

And of course, if you tune to a receiver spur that is influenced by

I enjoyed building my two K3's. To me it adds to the radio and the

I always enjoyed building kits and was looking forward to building a K3.
But my plans were altered by health issues and I had to go factory built.
And I found out 3 weeks ago when I tried to install the DVR option that it
was a god move.
Had real trouble just opening the radio up with 1 1/2 hands.
Just how did this post get in here? Isn't this the "Noisy K3 Receiver"

Using K3 + ALS600. About 40 Watts in gets about 425 Watts out from 2.3 to
4.1 MHz. No ALC. TX DLY = 020.

Hi Ken,

Note that the published specifications for the K3 say:
"Harmonic and Spurious: > 50 dB below Carrier (100W) typical."
So depending on which side of 50dB your spur is, it may be nothing to
worry about.

You will probably get a lot of opinions both ways. Those who spent the

glad they did. Most (nearly all?) who opted to do the kit, are probably

It only makes sense to buy factory built if you buy the K3 with all the
