Craig;
I can't comment specifically on the TX IMD performance since I wasn't
involved with that part of the design. The comments I made referred to
excessive broadband amplitude and phase noise that some transmitters
generate that can cover 100's of kHz of bandwidth. If you live near such a
transmitter running a kW of power, you can hear the transmissions across
much of an amateur band. We do understand that problem and worked to
minimize it as much as we reasonably could.

I was intrigued by Johns KI6WX comments on the K3's transmitter
design.

The K3 is designed to not only receive signals in a noisy RF
environment, but also to generate a much cleaner signal in transmit
How good is the transmitter IMD performance? I was also wondering
if the issue of TX ALC induced IMD was addressed? A problem thats
so common in many Japanese radios. Would the K3 meet the NTIA
Redbook Standard?
I was also wondering what final PA transistors or FET's are used
in the K3?
