I have used a Qt GUI Number Sink block for this purpose although it has
the rather disconcerting property of providing textual output as well
as a sliding scale, which can't be switched off.  You obviously need to
take the block's input before your AGC block (if any) and because it
comprises a linear display use logarithmic compression and/or some other
form of compression on that input in order to get meaningful results as
a signal strength monitor.
