Actually, my experience is different. If I transmit at the edges of the bandpass, my signal is attenuated due to the bandpass of the output stage. I hope I am saying this correctly. This is why I use split to ensure that the signal I transmit engages the full power of the KX3.
Now, I have read many times in this forum that the setup of audio based digital modes only needs to set the audio so you get 4 bars of alc (5th flickering) and then set the output power to 5w (in my case that is what I use). You set these independently of one another. Fine. I have done that. But, I have observed that if I don't use split mode and I respond to a cq at the edges of the bandpass (e.g., 200-300hz or 2500-2700hz), my signal is noticeably weaker. Have I misconfigured something on the KX3? The USB sound card I am using is many times wider than a typical USB signal. regards, Brian VE3IBW On Tue, Jul 4, 2017 at 2:38 PM, Bob McGraw K4TAX <rmcg...@blomand.net> wrote: > One anomaly which I've just observed with my K3S.
