Response to
Query
Tx Power Level
Increase N/A 3 bytes Query only.
Returns the increase in Tx power level, in dB (from the nominal setting) due to the action
of AUPC.
Range is 0.0 to 9.9 dB
Responds x.x if AUPC is disabled.
Example: PLI=2.3 N/A PLI? PLI=x.x
(see Description of
Arguments)
Tx Clock Source TCK= 1 byte,
value of 0 thru 2 Command or Query.
Tx Clock Source, where:
0=Internal
1=Tx Terrestrial
2= Loop-Timed
Note: When TCK is changed from Internal to Non-Internal, Clock Extension Mode will be
automatically changed to 0=None if it was 1=TxLock. Reply: TCK+
Example: TCK=0 (selects Internal) TCK=
TCK?
TCK*
TCK# TCK? TCK=x
