They DO have 3 levels of voice encryption/inversion, however, which is at least scanner proof.
X-Pand has absolutely no effect on squelch tail ("crash") elimination when listening to an XTN portable's transmission on another radio (Jedi, Waris, etc.).
On tranmissions w/PL, the XTN radio's PL reverse-burst is different from the Motorola standard, to be compatible with other manufacturers (Kenwood, etc.). Phase is inverted 180 degrees instead of the
M standard 270 degrees, causing other
M radios to not mute fast enough, causing the "crash".
In the XTN portables, X-Pand is enabled on frequencies whenever "narrow" (11k0f3e) bandwidth is enabled. Most of the frequencies in the 56-freq or 27 freq list are narrow-only but some are wide (16k0f3e) or narrow (11k0f3e) programmable. X-Pand is OFF whenever operating in "wide" mode on a frequency.
The UHF CLS series portables are narrow-only on all 56 UHF freqs in the list.
I have a pair of 15-channel VHF CP100 portables. They work great on MURS and that's what I use them for. The CP100 series portables look identical to the XTN portables but the model name/number is different and there are single and 15-channel models. The freq list is slightly different than the XTN portables in some models. I think the CP100 portables ARE the exact same radios as the XTN portables except for the different model name/number and the firmware inside the radio.
Battery life on my CP100 portables is very good and I would expect it to be the same on the XTN portables.
These radios (XTN and CP100 series) are LOUD when you crank the volume up, so you should have no trouble hearing them in noisy environments.
All of the freqs and programming instructions are listed in the owner's manual, so it pays to RTFM.
Good luck.
