This is, any DL signal detected in any DL enabled

in any UL enabled filter blocks all DL filters

Simplex mode checkbox control is only visible in devices with such capability. It allows
signal flow only in one direction, either uplink or downlink, at any given time. The chosen
direction is made automatically based on signal detection which, in turn, depends on
squelch. Therefore, turning on simplex mode automatically turns on squelch, both in
uplink and downlink sections, and disables these controls for the user. Besides, it also sets
squelch mode to "Not Linked" and disables this control, too. This is necessary since
otherwise the lack of RF input signal in downlink would mute the uplink RF input, thus
blocking all communication. The look of the general control frame in simplex mode is as in
next image:
