Does this mean that the wt of Lipo batteries doesn't count towards the 7 kg wt limit?

"The person in charge of a SUA which has a mass of more than 7 kg excluding its fuel but including any articles or equipment..."
No Steve, Lipos are not classed as fuel for purposes of definition, since they weigh the same charged as they do discharged.

Is a spectrum analyser really that much use? It can only give you a picture of the environment in the immediate vicinity of the receiver. You're potentially flying 500 m away and 120m up in an environment you cannot directly sample. You need to be able to identify and recover from bad situations as part of your basic piloting skills. This is based on personal experiences.
Our experience with RF interference was not caused by 2.4GHz/5+GHz transmissions, it was probably one of the mobile frequencies. Monitoring a single frequency band is really not that much use.I use the RF Explorer.
You can scan your take off and landing area for 2.4Ghz activity before flight, I agree with ZAxis about the distance issue but not all jobs need you to fly 500m away.
