RE: [BCD396XT] LTR scan speed
- I've also wondered why LTR systems have such a long dwell time on Uniden
scanners. If there is no carrier present, they shouldn't take any/much
longer than conventional channels. If there is a carrier, I can see a
slight dwell to check and see if it is an LTR signal, and then decode. The
GRE scanners do fly through with no perceivable dwell in the absence of a
carrier, but obviously Uniden does things differently. Not a biggie, but
with several LTR systems, it does drag the overall speed down a bit.

Subject: [BCD396XT] LTR scan speed
I have a question about scanning LTR systems:
I'm curious as to why the unit sits on each LTR system for a "relatively"
long time (a full second or so), even though there's no carrier present on
any of the LCNs. With Motorola systems, if the control channel isn't
present, the unit flies right by it.
The hold time is set to zero on the systems, and they're relatively small
(only 2 or 3 LCNs each).
It seems logical to me that the scanner should be able to quickly sample the
LCNs (at conventional channel scanning speed) and simply keep going if
there's no carrier present. I'm assuming that there's a technical
explanation for this.
