[Elecraft] Receivers?

[Bill Frantz]

I have both a K3 and a KX3 and have used a K2. The principle 
reason I would consider buying a K2 is for the joy of assembling 
the kit.

When I compare the KX3 and the K3, I think of the KX3 as being 
about 90% of the K3, but many options are standard on the KX3 
but extra cost on the K3. (Note that the K3S is the same as the 
K3 in these examples.) Examples include:

The digital voice recorder -- standard on the KX3. Separate 
board for the K3. Two memories on the KX3 and 4 on the K3.

Dual Watch on the KX3 is a good example of the 90%. The same 
functionality is available on the K3 with the subreceiver. The 
difference between the two receive frequencies is limited on the 
KX3 while the K3 subreceiver is a separate receiver and can 
receive on different bands. Also, the dual watch needs to have 
wide enough bandwidth to cover both frequencies which can raise 
the received noise level.

General coverage: Standard on KX3, needs additional filter board 
on K3.

High stability local oscillator: Optional board for K3. 
Calibration procedure for KX3. (I suspect the K3's solution is 
more stable.)

100W amplifer: Internal on K3. A separate unit on the KX3.

The KX3 is a heck of a good value, and portable too.
