Narrow vs. wideband in out of tune radio

Post by Renamon »

I have a radio taht need to be tuned a little. When it recieves a signal (analog or digital) it unmutes slightly quicker with a wideband signal than it does with a narrowband signal.

Does that sound normal? My logic tell me yes, since in narrowband there is less signal for the radio to grab onto... :D

Maybe. S/N ratio is what squelch circuits work on, but PL/DPL circuits shouldn't care as long as they decode. Someone would have to do experiments to prove whether it matters or not.

When I said digital, I was meaning P25. It seems P25 narrowband unmutes "slower" than wideband P25. This is in the clear, with fast unmute disabled.

I have also noticed that it is just this one radio too, all the others have the same "speed" so to speak. So there could be other factors at work here.

Jeff,

Believe it or not, we have a wideband ham P25 repeater here, or at least the owner claims it to be that. Actually we have two, with one wide and the other narrow.

On P25 wide refers to mixed mode. P25 by definition is always narrow. The analog would be wide and I suppose the receiver is wide but the P25 transmit is narrow.

The repeater operator is probably referring to Wide Pulse mode used in simulcast systems.
