How to tell the bandwidth of an ASTRO conventional channel?

Post by w2sjw »

Guys,

I have a few jurisdictions near me that use ASTRO conventional for PD operation. Is there any way to tell whether the channel should be in 2.5k or 5k bandwidth mode? Is it something I could tell by looking at the emission designators in their licenses?

I'm pretty sure C4FM is 12.5KHz by default

Jeff,

Thanks for the quick reply - I was confused with the fact the radio still lets you set it at 2.5k or 5k, regardless of the fact that the channel has been set to ASTRO.

The deviation in P25 mode is always 2.83 KHz regardless of what the deviation is set to. The 2.5 or 5 KHz setting only applies when the mode is analog or mixed mode.

I will 2nd this in that the setting only applies to analog. P25 does not change.
