TRX-1: Coast Guard P25

[waltmapb]

I am using the software to import the Coast Guard P25 VHF nets and assign to a scanlist.
When I create the scanlist the system always shows as analog although they should be digital P25 with a NAC of 193.

It seems that a conventional scanlist will only show the system as analog and it cannot be changed.

Since the objects are NFM and digital will they scan properly even though the system label in the scan list is analog?

The Coast Guard generally uses a NAC of N293, not 193.

My typo, correct NAC is 293.

Although the channels import as FM should not all P25 channels be NFM?

A P25 modulated assigned channel will ignore whether it is set for FM or NFM. P25 is digital modulation. Not FM or NFM so it makes no diff.

So what mode should be selected for a P25 conventional channel ?
the choices in Easy Scan are:
AM
FM
NFM
AUTO
DMR

Or does it even matter?

The FM and NFM setting uses different filters and could make a noticable difference to the reception.

P25 uses NFM bandwitdh for a channel.
