APCO P-25

New digital modulation type, labelled as "APCO Project-25" P-25 pretty much is the same modulation that cell phones use. P-25 is supposed to give better voice quality, but there really is no differance. Plus I need to buy a new radio scanner now.

There are two types of P-25, 3,600 baud and 7,200 baud speeds.

white noise

(Repeater Term) is a scientific term used to describe a spectrum of broad band noise generated in a receiver's detector and sampled to control the receiver's squelch. This term is often incorrectly used in repeater work to describe the sounds heard when the received transmission is noisy and hard to understand, usually attributed to a weak signal and the repeater receiver limiters are not engaged.

Many people do not understand the correct usage of 'white noise'

PRC-77

the PRC doesn't stand for anything.

the PRC-77 (and the improved PRC-770) are military VHF FM transcievers, that have been used sence 1960, and are slowly being phased out because the US Army likes them.

Frequency Coverage:
30.0000 to 76.0000 MHz
channel spacing:
50 kHz
channels:
920
Power Output:
5 watts
Range:
10 miles on a bad day
5 miles when the VC are shooting at you
30 miles when you get back to base

PRC-77s are used as manpack radios (straped to the back of GIs and used for unit-to-unit communications), if you've ever seen the movie "Platoon", the PRC-77 is the radio that all the Americans are carrying on thier backs.
or they are installed as radios in Humvees and tanks. (i.e. all the antennas on military viecles are connected to PRC-77s.

widly copied by every NATO member, so all the good guys can talk to each other.

"Roger, get the PRC-77 on 41.75 and call HQ"
