Checking for Interference on a Receive Channel
You can use the Signal Level page (Diagnose > RF Interface > Signal
Level) to look for sources of interference across a range of receive
frequencies.
The chart on this page has two lines. One shows the current RSSI
measurement for the selected frequency. The second shows a historical
trace of peak RSSI readings on that frequency.

Marshaling or Transmit Delay
As an IP connected base station, transmitters must buffer the signal to be
transmitted so that variations in delay in the IP network do not cause the
transmitter to underrun.
Non-simulcast channels use a configurable transmit delay. The amount of
transmit delay required varies with the QoS (specifically jitter) of the IP
transmission network.
Transmitters in a simulcast channel must all begin transmitting
simultaneously, therefore the configured value of the marshaling duration
must allow for the worst case network delay, including delay variation
(jitter).
