Starting at 24 MHz is just fine for chasing impulse noise like that from 
faults on the power distribution system, but is useless for chasing 
noise generated by most electronic sources like switching power supplies 
and clocks of various sorts.

Paul's suggestion of an SDR with suitable frequency coverage and user 
software seems a far better solution for chasing those electronic sources.
