Well, I have had the SR7 for a while and there a only a couple things I'm dissapointed with from it. One is it's "Spec Mode", which is basically the only reason I bought it. I was under the impression when I bought it that it would tell you the exact frequency of the radar, but that is not how ever what it does.
The way it works:
- Hones into general frequency, generally only for a weak signal, IE 24.100
- Selects from the closest freqency, IE 24.122, 24.158, 24.169, 24.190 are my most common, but never any numbers in between.
It works basically the same as that great "Lock Out" feature, by breaking it down into 8 segments of K band. I guess all Escort products work this way. That being said, I don't think it can accurately identify multiple sources on close to the same frequency.
