Perhaps you're hearing cordless phones in the 902 - 928
MHz range and misidentifying them as cell phones. I get those signals too, but even a novice scanner enthusiast can tell the difference ... especially when these "mirror" signals remain active with identifiable traffic, and can be verified by any unblocked rig in the designated cellular range. For instance, a signal heard on 907.0750 MHz in (factory pre-set) step on my BC80, will show up as 886.3500 MHz in NFM@30k step on the unblocked radio. Nope ... I can't explain it boys, and I'm eagerly learning more all the time, but I figure a passion like ours knows no boundaries. It's just a matter of operating the equipment and acclimating to the mechanics of the trade. This is FUN stuff. I was impressed with the BC80XLT I reviewed in Sept. 2004 Monitoring Times. It is very simple to operate so it can serve as a good first scanner. The triple up-conversion circuitry performs much better than older style economy models employing a 10.8 or 10.7 MHz first IF, so it is suitable as a second "knock around" scanner or more advanced users, too. Interesting observation Bob ... as the seasoned veteran of a BC80XLT and new owner of an AOR MK3, that's just how I feel, although I'm a still more of a BC80-level user. However, that temporary status doesn't interfere with the sheer pleasure of catching smug cops talking to each other "privately" on their cell phones. I mean, the new breed of militant law enforcement can't very well discuss entrapping people on the unblocked airwaves, now can they? |

It's a 10.3625 MHz image. (Which probably means that
the scanner needs a bit of alignment.) Makes sense Al, and I'm sure that's the case here, but why would I want to align anything when I'm receiving the full cellular range on a BLOCKED Uniden scanner made in 1995? However, I'd really like to know what formula was used to come up with that "image" number. |
