Well I think that was the idea with the NRP tower, but this one will I guess be a bit more of a sore thumb, hence the kerfluffle.
Spectrum sweeper on my current stuff works a little differently, but I did used to get awesome success with Close Call on my old BC75XLT- worked a charm to find anything near me. I'd still use it if it would cover up to 900 mhz just to get the close-call feature.
