c_ntua i had read that project 25 is interoperable many times but had not stopped to consider exactly what that would require. it is more than just the police and fire but rather the whole government agencies such as utilities like water and electricity along with airports and fuel transportation with other safety agencies as health and welfare et cetera. so that for example some individuals from new york and california or where ever could go to something like katrina and just fit in with their system or where ever . there must be incompatibilities with the current system that i am unaware of.

on this point you are correct. it can be faked, but I have never misrepresented myself on this forum, and anyone reading this will back up that claim.
kinda hard misrepresent yourself when you will not directly answer any of the questions. ok you heard him say " I have never misrepresented myself on this forum, and anyone reading this will back up that claim. " so anyone willing to put your reputation on the line and step forward and verify and back up this claim of elkvis ? i would prefurr to hear from someone that is not a buddy of elkvis so lets see what we get ?

you are the one trolling for trolls. that is trolling and that makes you the only one here that is a trolloroidous. or if you were on skates a trollorollerroidus.

i gave you an opportunity to show that you have some skill that which you would expect from a amateur radio operator. i had asked only one question that you could not most likely pooggle the answer. i did not ask you to do the entire project 25 research. i did not ask you to do an entire thesis on the project 25. i did not ask you to an entire spiel. i only asked one question for a detailed answer which you could not answer. what you have done is a total loss of creditability.

As an Extra class amateur radio operator, licensed in the USA for the last 20 years, I have some knowledge of these things.
this sentence structure implies that you were licensed as an extra class amateur in the usa for the last 20 years. you said that you have some knowledge of these thing and yet fail to directly answer only one question. your sentence structure and grammar indicate that you have some very nigerian mannerisms. are you from nigeria ? do you have dreadlocks ?

there are two different coders in use. amr uses 4.75 to 12.2 kbs and evrc uses four different rates. the mbe separates the voice into four different frequency bands. then the dsp preforms a voice or noise analysis in each speech band and discards nonvoice. low bit vocoder is used for narrow band radio transmission. 64 thousand bits per second digitized. 2800 bits of forward error correction is added with 2400 bits signaling and 4400 bits voice to make the 9600 bits per second channel capacity. depending on which mode used. dialup buffers the audio while project 25 is live. it plays it as fast as it gets it. while one point of voice is played the electric charge starts to diminish thus causing a random starting location for the next bit of data. being played slower because of transfer rate the next point of data is farther away from the previous point or original signal. thus giving that breeze affect. it is like two paws scratching a chalk board with their nails. lets see how long it takes you to realize that i already put up the link to the files.

a faster speed will cure some of it but not all.
