I used to build a pretty good sounding POTS line extender using 12.5 KHz and a compander. But yeah, ain’t nothing like a good old FM rig.

I'll sum it up. a.. All Two Way channels are getting narrower b.. Digital is the way things are going to continue to go c.. It ain't going back It doesn't matter that 95% of the geography doesn't need it. These trends are driven by the dense population areas that require more spectral efficiency and there isn't anything anyone is going to do about it. FirstNet is the same thing with different bands. Second, try 12.5KHz or 6.25KHz without digital and see what that crap sounds like. I lived through it and companding was a lot worse. Most of you aren't old enough to remember when the channel sizes were all 50KHz instead of 25KHz and everything sounded beautiful. Those days aren't coming back. No matter what vocoder is used some tuning to dialect and speech helps. Having said all that, some voices are not going to sound good on any narrowband. If you come from analog wideband to narrowband digital it all sounds like crap. You get used the the difference and there is no issue understanding words or intent. In short; everything sounds better wide band, there is no wide band, get over it. On Wed, Oct 4, 2017 at 5:05 PM George Skorup <[email protected]> wrote: P25 Phase-I uses the IMBE vocoder. Yeah, that kinda sounds like shit. Phase-II uses the AMBE+2 vocoder, but then you have the TDMA split into two time slots, i.e. half the bandwidth. Still better than IMBE. DMR/TRBO is also 2-slot TDMA using AMBE+2. I use it and don't think it sounds that bad at all. Add encryption overhead and it sounds worse, regardless of the vocoder used. Bandwidth, bandwidth, bandwidth. On 10/4/2017 9:27 AM, Matt Hoppes wrote: But it does. In a stressful situation the last thing you need is to not be able to understand communication on the radio.

For some reason digital radio get sold over and over and over to Public Safety as being the cats meow, but here in Pennsylvania is a great example of how it just doesn't work. We spend millions of dollars retrofitting a system just to start trying to go to another one. The last thing you need in a stressful situation is everyone sounding in the abbreviated and codex scaling down because the signal level going to repeater isn't good On Oct 4, 2017, at 10:13, Jason McKemie <[email protected]> wrote: The zones could have been wrong - it happens.

Does this seem odd to anyone else? I feel like if there is an alarm going off, the fire panel would indicate the room it was in. "The SWAT team utilized the alarm activated by the smoke to determine Paddock's location. But it still took SWAT some 20 minutes from the time they arrived at the hotel to pinpoint the exact room Paddock was located in, according to The Post."
