When operating split with receive slice A and transmit slice B the signal strength of A decreases when engaging slice B. This just started doing this. I am not sure I am overlooking something or I have an issue.
Sometimes when you open the 2nd slice the audio output of the 2nd combines with the first and makes it more difficult to hear if you're listening to a weak signal. I always mute the 2nd slice unless I'm listening to the pileup and the DX signal is strong enough to be heard in the output. You can also leave the DX signal "centered" between L and R ears (speakers) and move the slice 2 off to the right ear - that often helps when trying to hear both at once. That is my experience, anyway. Hope it helps.
