[Elecraft] Fwd: K4 distortion

[Raymond]

> The K4 will sample the output signal, feed it to the unused rcvr ADC and develop a correction signal to the transmitter. There is a RF sample in port that can be used to feed external sample to ADC. The transmitter monitor option in the P3 moves into the K4.
> ADC is separate small module that can be changed to allow for technology improvements
