Re: Motorola HT1250 receive audio delay

Many times, the RX/TX delay is improperly set.
I still do not 'get' why this particular setting has a minimum setting of 1 second to switch from RX to TX.
This makes no sense to not make this setting more adjustable, as in allowing mS changes instead of that 1 second setting.

since you admit to operating the duplexer at below the minimum split, you are losing any separation of TX and RX, allowing one to cause desense to the other, I.E..TX into RX side.
