To change the gain on a variable gain TMA, enter the desired value of gain in the 2. New
Gain field, and click on Set Gain. In Figure 23-7, current gain was 6 dB, and a new gain
of 8 dB is being set. Note that for a fixed gain TMA, the Set Gain button is not available.
Also this screen displays a list of TMA subunits that has the same frequency bands (TMA Rx
and TMA Tx) as that of the current subunit. By selecting the checkbox “Change gain on other
subunits with the same frequencies,” the listed sub units will also be set to the New Gain value
when Set Gain is clicked. If this checkbox is not selected the New Gain value is sent only to the
current subunit.
