picket fencing

(Repeater Term) A condition experienced on VHF and above where a signal rapidly fluctuates in amplitude causing a sound akin to rubbing a stick on a picket fence. If a repeater user's signal isn't strong enough to maintain solid access to the machine's input (such as when operating from a vehicle passing beneath underpasses or through hilly terrain), the signal would be hard to copy because of a pronounced, rapid fluttery or choppy characteristic.

We can't copy you, you're picket fencing really badly.

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.
