Select the desired channel and power level, click "Transmitter ON", then click Execute.
The reason why this is a temporary solution is because in some instances, the AFC and
AGC are not disabled, with the results that the signal will not be stable in frequency and
will not respond to AGC PDM adjustment. If this is the case, manually disable the AFC
and AGC using the "DSP Memory" dialog box shown below.
Choose the "Data" option in the "Address Space" field, type in the address, leave the
"subcount" entry at "1", then click Add button. The address will then be displayed in the
field in the lower half of the dialog box. Use this method to enter in both the AFC Disable
and AGC Disable addresses. These addresses can be obtained from R&D, and they can
change with software version. This is the reason this method is temporary.
Once both addresses are entered, check "Periodic Read On", then click Stop button. Then
click the Read button, which will display the values in both addresses. Both should be
"1". Change both to "0" by clicking on the "1", which will highlight the data in the
address, then you can edit the contents and change the "1" to a "0". Enter a return on
your keyboard to enter the new value. Once the contents of both addresses are changed
to "0", click the Write button, which writes them into the phone. This data will remain in
the phone until the phone is powered down.
