Like Jim B. said. The Aero Spectra is a true professional grade instrument which can even predict battery failure in a tx. The read out gives out put in db's, has a two phase refresh rate to see spikes in interference etc. The adjacent channel comparison when in zoom mode is an eye opener. You can visually tell who has a sloppy transmitter. This will put to rest all the arguments as to what kind of transmitters with which antennas are accurately spreading signal. JD
