"The speech processor, mic gain and ALC circuits need some design attention.
The transmitter in the K3 is very poor. The RF speech processor produces a
lot of IMD on the signal. It's a raspy and nasty kind of product that bleeds
from the transmit signal. What I was hearing was not pleasant. The K3 has
the infamous ALC induced leading edge splatter/IMD problem. Even the older
K2 is better in this area. If you test the K2 under same conditions at
5,10,15 and 20khz you get almost no IMD or splatter. As you reduce the power
level on the K2 between 50 and 70 watts there is no detectable splatter with
the speech processor set to 2:1 or 3:1 compression ratio. In contrast the
moment you turn the K3's speech processor on you can hear leading edge
splatter at 10,15 and 20khz. I might have a faulty unit and I am not really
sure."
======================================
I think, that the SOLARDX is really not K3 user.
And it IMD-problems are from another HAM-RIG - not K3.
All these problems I read in opinion for other radio.
